     DESCRIPTION OF EMBODIMENTS 
       [0045]    As shown in  FIG. 1 , referring to the first embodiment of the portable food processor of the present invention, the portable food processor comprises the container  100 ′, container cover member  200 ′ and the food processing member  300  within the container  100 ′. The container cover member  200 ′ comprises the cover that closes the aperture of the container  100 ′, the pull rod member  230 ′ that protrudes on top of the cover, and the transmission device  250 ′ that is arranged in the cover. The pull rod member  230 ′ rotates the food processor member  300  relative to the container  100 ′. The spinning of the food processing member  300  relative to the container  100 ′ allows the draining, cutting up or mixing of the food. 
         [0046]    As shown in  FIG. 2 ,  2   a , in this embodiment, the cover is assembled from the upper shell  210 ′ and the lower shell  220 ′. The upper shell  210 ′ and the lower shell  220 ′ are securely attached together by screws or equivalent fasteners, and the cavity between the upper shell  210 ′ and the lower shell  220 ′ is where the transmission device  250 ′ can then be placed. The lower shell  220 ′ fits onto the aperture of the container  100 ′, so that lower shell  220 ′ covers the aperture of the container  100 ′. The pull rod member comprises the sliding track  231 ′ and the pull rod  233 ′ within the sliding track  231 ′ that is between the upper shell  210 ′ and the lower shell  220 ′. The pull rod  233 ′ fits into the sliding track  231 ′, so that the pull rod  233 ′ can slide back and forth on a level plane. 
         [0047]    Preferably, a handle is mounted to an end of the pull rod  233 ′, an elastic member adapted for allowing it to be pulled and be extended is mounted to an other end of the pull rod  233 ′. In this embodiment, the elastic member is a spring  233   b ′. An end of the spring is mounted to the convex member  233   a ′ on the pull rod and the other end of the spring is mounted to the upper shell  210 ′. By using the handle to pull the pull rod  233 ′ out of the sliding track  231 ′, the spring  233   b ′ will return the pull rod  233 ′ back into the sliding track  231 ′, so it is easy to operate. 
         [0048]    As shown in  FIG. 2 , the handle  236 ′ can be of D-shape, there is a connecting rod  237 ′ which connects the handle and the pull rod  233 ′. The connecting region between the connecting rod  237 ′ and the pull rod forms a step  237   a ′, there is sleeve connector  238 ′ is arranged on the connecting rod  237 ′, an end cap  239 ′ is arranged at the end of the connecting rod  237 ′. There is a positioning rod  237   b ′ arranged at the end portion of the connecting rod  237 ′ that passes through the connecting rod  237 ′, the sleeve connector  238 ′, and the end cap  239 ; so that the end cap  239 ′, sleeve connector  238 ′, and the connecting rod  237 ′ are securely connected in position. There are sleeve apertures  236   a ′ at both ends of the D shape handle. One side of the D shape handle is fixed in position between the step  237   a ′ and the sleeve connector  238 ′, and the other end is fixed in position between the sleeve connector  238  and the end cap  239 , so that the D shape handle is formed by the sleeve connector  238 ′ set between the two ends. This secures the D shape handle in position at the end of the pull rod  233 ′, and ensures that the D handle  236 ′ can rotate on the axis of the connecting rod  237 ′. When in use, the hand would hold onto the D shape handle  236 ′ to move the pull rod  233 ′ in reciprocating movement conveniently. One of the side edges of the pull rod  233 ′ has a gear rack  235 ′, to mesh with the gear in the transmission device  250 ′, so that the pull rod  233 ′ drives the transmission device  250 ′ that in turn rotates the food processing member  300 . 
         [0049]    As shown in  FIG. 2   a , the handle  234 ′ can be T shape. The T shape handle  234 ′ comprises a top handle shell  234   a ′ and the lower handle shell  234   b ′, there are convex element  234   c ′ on the upper handle shell  234   a ′ and lower handle shell  234   b ′ and the groove  233   a ′ on the end of the pull rod  233 ′. By allowing the upper and lower handle shell  234   a ′,  234   b ′ to secure in position at the end of pull rod  233 ′, the T shape handle  234 ′ is therefore mounted at the end of the pull rod  233 ′. When in use, the hand would hold onto the T shape handle  234 ′ to move the pull rod  233 ′ in reciprocating movement conveniently. An improvement would be to include a concave region  211 ′ on the cover at the end of the sliding track  231 ′ (the pull rod end that is closest to the T shape handle), the concave region  211 ′ and the T shape handle  234 ′ corresponds; when the pull rod  233 ′ slides into the sliding track  231 ′, the T shape handle  234 ′ fits into concave region  211 ′, so that the cover appears uniform in shape. The handle at the end of the pull rod can be other shapes as desired. 
         [0050]    As shown in  FIGS. 2 and 4 , the transmission device  250 ′ comprises the driving gear member  251 ′, the driven gear member  252 ′, and the driven shaft  253 ′. In particular, there is a first positioning rod  221 ′ located on the top and near the side of the lower shell  220 ′ close to the edge of the upper shell, there is an aperture  212 ′ located on the upper shell  210 ′ corresponding to the positioning rod  221 ′. The driving gear member  251 ′ comprises a positioning knob  213 ′, the upper transmission gear  251   a ′ and the lower transmission gear  251   b ′ which are able to be rotated coaxially. More specifically, the positioning knob  213 ′ goes through the aperture  212 ′ and extends above the upper shell  210 ; the lower portion of the positioning knob  213 ′ has a larger circumference than the aperture  212 ′. Furthermore, the positioning knob  213 ′ has a convex element  213   a ′ at the bottom of the positioning knob  213 ′, there is an aperture  251   a   1 ′ adapted to be corresponded to the convex element  213   a ′ being arranged at the top end surface of the upper transmission gear  251   a ′ near the center shaft position, there is an aperture  251   b   1 ′ adapted to be corresponded to the first positioning rod  221 ′ being arranged at the bottom end surface of the lower transmission gear  251   b ′ near the center shaft position (see  FIG. 5   b ). By arranging the appropriate shaft&#39;s dimension, upper and lower transmission gears  251   a ′,  251   b ′ are able to be rotated coaxially and can be fixed in position on top of first positioning rod  221 ′ and through the aperture  212 ′ in the upper shell with the positioning knob  213 ′, thereby positioning the driving gear member  251 ′ on the first positioning rod  221 ′. The upper transmission gear  251   a ′ meshes with the gear rack  235 ′ on the side of the pull rod, the lower transmission gear  251   b ′ meshes with the driven gear member  252 ′. If it is required by the user, the first positioning rod  221 ′ can be arranged on the top of the upper shell  221 ′, and correspondingly the driving gear member  251 ′ can be set on the first positioning rod  221 ′, so that the pull rod  233 ′ can rotate the first positioning rod  221 ′ by moving the driving gear member  251 ′. 
         [0051]    In this embodiment, there is a second positioning rod  222 ′ arranged on the top and near the side of the lower shell  220 ′ close to the edge of upper shell  210 ′. One can arrange a screw hole in the middle of the driven gear member  252 ′, so that the driven gear member  252 ′ can be fixed in position on the top and close to the edge of the lower shell  220 ′, which means the driven gear member  252 ′ sits in the cavity between the upper and lower shells  210 ′,  220 ′. The driven gear member  252 ′ comprises the upper driven gear  252   a ′ and the lower driven gear  252   b ′ which are able to be rotated coaxially, the upper driven gear  252   a ′ meshes with the lower transmission gear  251   b ′, and the lower driven gear  252   b ′ meshes with the driven shaft gear members  253   b ′ on the driven shaft  253 ′. Similarly, if it is required by the user, the second positioning rod  222 ′ can be arranged on top of upper shell  221 ′, and then the driven gear member  252 ′ is arranged on the second positioning rod  222 ; or one can use the same positioning method as driving gear member to arrange the driven gear member  252 ′ onto the second positioning rod  222 ′. 
         [0052]    As shown in  FIG. 4 , inside the sliding track  231 ′ which is formed by the upper shell and lower shell  210 ′  220 ′, there is an aperture  231   a ′ on the wall of the sliding track. The upper transmission gear  251   a ′ is arranged between upper and lower shells  210 ′,  220 ′ through the aperture  231   a ′ and meshes with the gear rack  235 ′ on the side of the pull rod inside the sliding track  231 ′. When the pull rod  233 ′ is moved, the gear rack  235 ′ on the side of the pull rod  233 ′ meshes with the upper transmission gear  251   a ′ of the driving gear member, in turn rotating the driving gear member; the lower transmission gear  251   b ′ of the driving gear member meshes with the upper driven gear  252   b ′ of the driven gear member, in turn rotating the driven gear member  252 ; the lower driven gear  252   b ′ of the driven gear member meshes with the driven gear  253   b ′ on the top of the driven shaft, in turn rotating the driven shaft  253 , thereby rotating the food processing member  300 . 
         [0053]    To ensure the driven shaft  253 ′ only rotates in one direction when the pull rod  233 ′ is moved back and forth, it is preferable to install a clutch  410  in the transmission device. In this embodiment, the clutch  410  is installed in the driving gear member  251 ′. Specifically, as shown in  FIGS. 5   a ,  5   b ,  6   a ,  6   b , and  6   c , the clutch  410  includes the toggle wheel  411  and the pawl  412 . In order to arrange the toggle wheel  411  and the pawl  412  in position in between the upper transmission gear  251   a ′ and the lower transmission gear  251   b ′, there is a housing between the upper and lower transmission gears  251   a ′,  251   b ′. In which the toggle wheel  411  and the pawl  412  are both arranged inside the housing. In this embodiment, there are three pawls but there can be one, or two, or more as needed. 
         [0054]    Specifically, in this embodiment, there is a ring shape convex element  414  on the bottom end of the upper transmission gear and a concave region  415  on the top of the lower transmission gear. When the ring shape convex element  414  and the concave region  415  couple together, it forms the housing for the toggle wheel  411  and the pawl  412 . There are toggle pieces  411   a  around the toggle wheel and a center hole  416  in the middle. In this embodiment there are 3 toggle elements  411   a  evenly distribute circumferentially around the toggle wheel  411 . There is a position limiting concave region  413  inside the ring shape convex element  414  that is shaped around the toggle wheel  411 ; in the center of the position limiting concave region  413 , there is a positioning rod  418  which corresponds to the center aperture  416 . When the center aperture  416  is arranged on the positioning rod  418 , the toggle wheel  411  can rotate axially around the positioning post in a set direction. 
         [0055]    The concave region  415  of the lower transmission gear is of a ring shape; there are teeth  419  in the curved walls of the concave region  415  forming the ratchet groove  415   a . There is an aperture  414   a  in the ring shape convex element  414  of the upper transmission gear; this allows the pawl  412  to extend out from the position limiting concave region to connect with the teeth  419 . There is a positioning aperture  413   a  on the bottom of the position limiting concave region  413  which matches up with the shaft  412   a  that stands up on the top of pawl  412  (see  FIG. 6   c ), positioning the pawl  412  within the position limiting concave region  413 ; there are convex elements  411   b  at the end of the point of contact between each of the toggle elements  411   a  of the toggle wheel and the position limiting concave region. The bottom of the position limiting concave region has a corresponding curved concave element  413   b  to the convex element  411   b , which rotates around the toggle wheel axis along the curved concave element for a certain angle of rotation. The degree of angle is determined by the size of the curvature of the curved concave element  413   b.    
         [0056]    As shown in  FIGS. 6   a  and  6   c , when the upper transmission gear  251   a ′ rotates, the upper transmission gear  251   a ′ rotates coaxially with the pawl shaft  412   a  as it corresponds with the position hole  413   a  of the limiting groove, so that the pawl shaft  412   a  moves towards the toggle elements  411   a  of the toggle wheel. At this time the convex element  411   b  of the toggle wheel will be stationary but the curved concave element  413   b  at the bottom of the position limiting concave region and upper transmission gear will rotate coaxially with the upper transmission gear  251   a ′. That is the curved concave element  413   b  will slide with respect to convex element  411   b , causing the distance between the convex element  411   b  and the pawl shaft  412   b  to decrease. The toggle element  411   a  will drive the pawl  412  to rotate around the pawl shaft  412   a , hence pushing the pawl  412  towards the outer edge of the convex element  414 , causing the pawl  412  to catch with the teeth  419  in the concave region, driving the lower transmission gear  251   b ′ to rotate. At this time, the clutch is in the engaged position, with the upper transmission gear  251   a ′ rotating in sync with the lower transmission gear  251   b′.    
         [0057]    As shown in  FIGS. 6   b  and  6   d , when the upper transmission gears  251   a ′ rotates in reverse direction, the upper transmission gear  251   a ′ rotates in reverse direction with the pawl shaft  412   a  as it corresponds with the position hole  413   a  of the position limiting concave region, so that the pawl shaft  412   a  moves away from the toggle element  411   a  of the toggle wheel. At this time the convex element  411   b  of the toggle wheel will be stationary but the curved concave element  413   b  at the bottom of the position limiting concave region and upper transmission gear will rotate in reverse with the upper transmission gear  251   a ′. That is, the curved concave element  413   b  will slide in reverse to convex element  411   b , causing the distance between the convex element  411   b  and the pawl shaft  412   b  to increase, the toggle element  411   a  separates from the pawl  412 , the teeth  419  in the concave region drives the pawl  412  to rotate in reverse around the pawl shaft  412   a , so that the pawl  412  separates from the teeth  419 . At this time, the clutch is in the disengaged position, so that the upper transmission gear  251   a ′ will not drive in sync with the lower transmission gear  251   b′.    
         [0058]    Through the clutch, when the pull rod  233 ′ is moving back and forth, when the gear rack  235 ′ is traveling in one direction, the upper transmission gear  251   a ′ through the clutch  410  automatically engages, driving the lower transmission gear  251   b ′ to rotate coaxially, thereby activating the driven gear which activates the driven shaft  253 ′ to rotate. When the gear rack  235 ′ is moving in reverse direction, the clutch  410  is automatically disengaged, so that the upper transmission gear rotates in reverse direction, but the lower transmission gear  251   b ′ still rotates in the original direction from inertia, thereby maintaining the effectiveness of the portable food processor. The way the clutch does it automatically makes the operation very convenient. 
         [0059]    The said clutch  410  may also be arranged in the driven gear member  252 ′ when it is needed, in which the toggle wheel  411  and the pawl  412  of the clutch  410  can be arranged in the region between the upper driven gear  252   a ′ and the lower driven gear  252   b′.    
         [0060]    As shown in  FIGS. 4 and 3   a , in this embodiment, there is a shaft aperture  223 ′ at the center of the lower shell  220 ′ and the driven shaft  253 ′ is rotationally mounted to the shaft aperture  223 ′. The bottom portion of the driven shaft  253 ′ passes through the shaft aperture  223 ′ and extends below the cover to correspond with the food processing member  300 . There is a driven shaft gear member  253   b ′ on the top of the driven shaft  253 ′ that meshes with the lower driven gear  252   b ′. To ensure that the driven shaft can move freely in the lower shell, in this embodiment, there is a center aperture  224 ′ in the center of the lower shell  220 ′, a latch plate  258 ′ at the center aperture  224 ′, and a shaft aperture  223 ′ in the center of the latch plate  258 ′ that corresponds to the driven shaft and there are latch hooks  258   a ′ around it. Correspondingly, there are latch apertures (not shown in the above figures) for the latch hooks  258   a ′ near the center of the lower shell  220 ′. By inserting the latch hooks  258   a ′ into the latch apertures at the bottom of the lower shell, the latch plate  258 ′ is positioned in the center of lower shell  220 ′. To increase the inertia when the driven shaft  253 ′ is rotating, a clump weight  254 ′ can be mounted to the driven shaft  253 ′ so that both rotate coaxially. The clump weight  254 ′ can be directly positioned on the driven shaft, or alternatively positioned on the connecting shaft which rotates coaxially with the driven shaft. Specifically, as shown in  FIGS. 3   a  and  4 , the clump weight  254 ′ is coupled to the driven shaft  253 ′ and positioned between the driven shaft gear member and the shaft aperture  223 ′ of the latch plate in this embodiment. 
         [0061]    The food processing member  300  may consists of working members for different purposes, such as blade accessory, mixer accessory, etc. according to what processing is needed in the container  100 ′, so that the food inside the container can be processed in various ways. In this embodiment the food processing member  300  will use the strainer basket member as an example for further explanation. 
         [0062]    As shown in  FIGS. 3 and 3   a , in this embodiment, the said strainer basket member comprises the strainer basket cover  361  rotationally connected to the bottom of the driven shaft  253 ′ and the strainer basket  362  rotationally positioned inside the food processor; the strainer basket cover is attached at the aperture of the strainer basket. Specifically, the strainer basket cover  361  and the strainer basket  362  may be locked together with a latch assembly. There is a center hole  361   a  in the center of the strainer basket cover  361 , that corresponds to the tapped end  253   d ′ at the bottom of the driven shaft  253 ′, with a locking nut  259 ′ at the bottom of the driven shaft. The center hole  361   a  of the strainer basket cover is placed over the tapped end  253   d ′ of the driven shaft and the strainer basket cover  362  is secured to the lower end of the driven shaft  253 ′ with the locking nut  259 ′, so that the strainer basket cover  361  is positioned at the lower end of the driven shaft  253 ′ and rotates coaxially with the driven shaft  253 ′. In the center of the bottom portion of the strainer basket  362  there is a concave part (not shown in the above figures) and there is a corresponding convex region (not shown in the above figures) on the bottom of the food processor. When the strainer basket is placed into the portable food processor, the driven shaft  253 ′ passes through the strainer basket cover  361  to rotate the strainer basket  362  along the center axis, therefore dispelling the water from inside the strainer basket  362 , succeeding in straining the water. 
         [0063]    In this embodiment, the food processing member  300  is not limited to the strainer basket member; another working member to consider is the blade assembly. As shown in  FIGS. 1 and 3   b , in this embodiment, the blade assembly of the portable food processor of the present invention comprises the connecting shaft  255  which coaxially couples to the bottom of the driven shaft, the center shaft  310  that is coaxially coupled to the bottom of the connecting shaft, and the blades  340  that are installed on the center shaft. As such, the top of the connecting shaft is coaxially coupled to the bottom of the driven shaft; that is the connecting shaft is rigidly connected to the driven shaft, specifically, to arrange a screw hole on the top of the connecting shaft  255  that corresponds to the bottom part of the driven shaft. There is a first center aperture  311  on the top of the center shaft  310  that corresponds to the bottom portion of the connecting shaft  255 . It is preferable that the lower part of the connecting shaft  255  is a hexagonal column  255   b , the first center aperture  311  is a hexagonal shape hole that corresponds to the connecting shaft  255 , so that the driven shaft  253 ′ through the connecting shaft  255  drives the center shaft  310  to rotate coaxially. There is an aperture (not shown in the above figures) at the bottom of the center shaft  310  and there is a convex element  113  (see  FIG. 10 ) at the inside bottom of the container  100  below the connecting shaft  255 . The aperture at the bottom of the center shaft corresponds to the convex element  113 , this positions the center shaft  310  rotationally connected to the bottom of the container  100 . If it is required by the user, the driven shaft can directly couple to the top of the center shaft, so that the driven shaft directly rotates the center shaft coaxially. 
         [0064]    Around the center shaft  310 , there are connection plates  330 . The connection plates  330  extend out from the shaft column radially and have positioning convex member  331  on the connection plates  330  that correspond to an end of the blades  340  that has position holes  341 . Screws or similar fasteners can be used to secure the blades  340  onto the connection plates  330 , so that the blades  340  will rotate around the center shaft  310 . According to need, there can be additional blades  340 . The blades distribute circumferentially on the center shaft column and when the center shaft is activated the blades rotate around the center shaft chopping up the food that is inside the container. 
         [0065]    As shown in  FIGS. 7 ,  8 ,  8   a , and  9   a , in the second embodiment of the portable food processor of the present invention, the portable food processor includes the container  100 , container cover member  200  and the food processing member  300  within the container  100 . As such, the container cover member  200  includes the cover that closes the aperture of the container  100 , the pull rod member  230  that protrudes on top of the cover, and the transmission device  250  that is arranged in the cover. The pull rod member  230  rotates the food processor member  300  relative to the container  100  through the transmission device  250  and the spinning of the food processing member  300  relative to the container  100  allows the draining, cutting up or mixing of the food. 
         [0066]    As shown in  FIGS. 8 ,  9  and  9   a , in this embodiment, the cover is assembled from the upper shell  210  and the lower shell  220 . The upper shell  210  and the lower shell  220  are securely mounted together by screws or equivalent fasteners, and the cavity between the upper shell  210  and the lower shell  220  is where the transmission device  250  can then be placed. The lower shell  220  fits onto the aperture of the container  100 , so that the lower shell  220  covers the aperture of the container  100 . 
         [0067]    The pull rod member comprises the sliding track  231  on the top surface (the top of the container cover member  200 ) of the upper shell  210 , the sliding track cover  232 , and the pull rod  233 . The sliding track cover  232  and the sliding track  231  correspond on the top of the upper shell  210  to form the gear rack, the pull rod  233  corresponds with the gear rack, so that the pull rod  233  can move back and forth inside the gear rack on a level plane. Specifically, the sliding track cover is arranged on the top surface of the upper shell  210  with screw  216 . Preferably, when holding a handle  234  and moving the pull rod  233  horizontally, the handle  234  and the pull rod  233  are rotationally connected by a shaft, it is preferable for the shaft to be perpendicular to the direction of the pull rod when it is moving but within the same level plane, this way when pulling on the handle  234  on the level plane, the handle  234  and pull rod  233  can rotate a little, so that the operation is not all stiff, and the action a little lively. One side surface of the pull rod  233  has gear rack  235  that meshes with the gear of the driving gear member, so that the pull rod  233  can drive the driving member to rotate the portable food processing member. 
         [0068]    As shown in  FIGS. 8 ,  9  and  9   a , the transmission device  250  comprises the driving gear member  251 , driven gear member  252 , and the driven shaft  253 . As such, there is a first positioning rod  221  located on the top and near the side of the lower shell  220  close to the edge of the upper shell, the center of the driving gear member  251  has a screw hole, the driving gear member  251  is fixed in position on the first positioning rod  221  through this screw hole by a screw, so the driving gear member  251  is positioned on top and near the side of the lower shell  220  close to the edge of the upper shell, therefore the driving gear member can be positioned in the cavity between the upper and lower shells  210 ,  220 . The driving gear member  251  has the upper transmission gear  251   a  and the lower transmission gear  251   b , the upper transmission gear  251   a  meshes with the gear rack  235  on the side of the pull rod  233 , the lower transmission gear  251   b  meshes with the driven gear member  252 . 
         [0069]    There is a second positioning rod  222  located on the top and near the side of the lower shell  220  close to the edge of the upper shell  210 , can also have a screw hole at the center of the driven gear member  252 , the driven gear member  252  is fixed in position on the second positioning rod  222  through this screw hole by a screw, so the driven gear member  252  is positioned on top and near the side of the lower shell  220  close to the edge of the upper shell, therefore the driven gear member  252  can be positioned in the cavity between the upper and lower shells  210 ,  220 . The driven gear member  252  has the upper driven gear  252   a  and the lower driven gear  252   b  that rotate in sync on the same shaft, the upper driven gear  252   a  meshes with the lower transmission gear  251   b , and the lower driven gear  252   b  meshes with the driven shaft gear member  253   b  which is on top of the driven shaft. 
         [0070]    As shown in  FIG. 8 , inside the sliding track  231  of the upper shell, there are apertures  217   a  and  217   b  in the corresponding sliding track wall and sliding track cover  232 , this allows the upper transmission gear  251   a  that is in the cavity between the upper and lower shells  210 ,  220  to access and mesh with the gear rack  235  on the pull rod that is inside the gear rack of the sliding track. When the pull rod  233  moves, the gear rack  235  on the side of the pull rod  233  meshes with the upper transmission gear  251   a  of the drive gear assembly, in turn rotating the drive gear assembly; the lower transmission gear  251   b  of the driving gear member meshes with the upper driven gear  252   a  of the driven gear member, in turn rotating the driven gear member  252 ; the lower driven gear  252   b  of the driven gear member meshes with the driven shaft gear member  253   b  on the top of the driven shaft, in turn rotating the driven shaft  253 , thereby turning the food processing member  300 . 
         [0071]    To ensure the driven shaft  253  only rotating in one direction when the pull rod  233  is moved back and forth, preferable to install a clutch  410  in the transmission device, the configuration of the clutch can be the same as in the first embodiment. 
         [0072]    In this embodiment, there is shaft aperture  223  located at the center of the lower shell  220 ; the driven shaft  253  is rotationally connected at the shaft aperture  223 . The bottom portion of the driven shaft  253  passes through the shaft aperture  223  and extends below the cover to correspond with the food processing member, there is a driven shaft gear member  253   b  on the top of the driven shaft  253  that meshes with the lower driven gear  252   b.    
         [0073]    In the present invention, the food processing member  300  may consists of working members for different purposes, such as blade accessory, mixer accessory, etc. according to what processing is needed to select from the different working member to use in the container  100 , so that the food inside the container can be processed in various ways. In this embodiment the food processing member  300  will use the mixer accessory as an example for further explanation. As shown in  FIG. 12 , the mixer accessory  300   b  comprises the center shaft  310   b  and two blades  350 ; one edge of the blade  350  is attached to the surface of the center shaft  310   b  circumferentially, the blade  350  can be manufactured as one with the center shaft  310   b  or securely attach to the center shaft  310   b  by other means. There is a center hole (not shown in the above figures) on the top of the center shaft  310   b  which corresponds to the bottom of the driven shaft  253 , so that the driven shaft can drive the center shaft to rotate coaxially with the driven shaft. If the bottom of the driven shaft follows the first embodiment as a threaded portion, then the center aperture would be a screw hole; if the bottom of the driven shaft is hexagon in shape with tapped end, then the center aperture will need to match the hexagonal shape of the tapped end; can follow the example of blade accessory in the first embodiment, by adding a connecting shaft between the driven shaft and the center shaft, so that the driven shaft turns the center shaft to rotate coaxially. There can be an aperture  312   b  located at the bottom of the center shaft which corresponds to the convex element in the inner bottom of the container  100 . In use, the driven shaft turns the center shaft to rotate, the blade  350  rotates around the center shaft  310   b , thereby mixing the food inside the container  100 , succeeding in the purpose of mixing the food. 
         [0074]    In order to increase inertia to the rotation of the driven shaft  253 , clump weight  254  can be added that turns in sync with the driven shaft  253  on the driven shaft  253 . Specifically, as shown in  FIGS. 8 ,  10 ,  10   a , and  11 , referring to the second embodiment, it is preferable to use a disc shape clump weight  254 , it is highly recommended to use a high density material for its construction, to increase inertia. There is a hexagonal shape connecting hole  255   a  on the top of the connecting shaft  255 , the bottom of the driven shaft has a corresponding hexagonal rod  253   a  to the connecting aperture  255   a  and the top of the driven shaft has a through hole  253   c , the screw passes through the through hole  253   c  of the driven shaft to screw into the top threaded portion of the connecting shaft  255 , this mounts the driven shaft  253  and the connecting shaft  255  in place and positions one on the top and one on the bottom of the lower shell  220 , and the connecting aperture  255   a  of the connecting shaft corresponds to the post  253   a  of the driven shaft thereby limiting any movement between the driven shaft  253  and the connecting shaft  255 , this way it is possible to fix the clump weight on the driven shaft, the driven shaft  253  via the connecting shaft  255  rotates the food processing member. If it is required by the user, the connecting aperture  255   a  and the post  253   a  can be of a polygon or a specialized shape, as long as it can eliminate any movement between the driven shaft  253  and the connecting shaft  255 . The clump weight is mounted on the same axis as the connecting shaft  255 , specifically, there is a hexagon shape shaft shoulder  255   d  at the top of the driven shaft and upper edge of the lower shell, there is a hexagon shape center aperture  254   a  at the center of the clump weight that corresponds to the shaft shoulder  255   d , therefore the clump weights rotates in sync with the driven shaft  253 , can vary the inertia when the driven shaft rotates. Similarly, as in the first embodiment, the clump weight can also be attached on the same axis at the lower part of the driven shaft. 
         [0075]    In the embodiment above, it is possible to install the first convex element  111  (see  FIG. 10 ) on the inner surface of the container  100  as well as along the axis line, that is the first convex element  111  goes from the top of the inner wall of the container  100  along the inner wall surface towards the bottom, this first convex element  111  can increase the friction between the food and the food processing member  300  when the food processing member  300  is rotating; so that the food will be chopped up more efficiently. The first convex element  111  can increase to four or more. In the embodiment above, two concave regions  112  can be installed on the outside surface of the container  100 , these two concave regions  112  evenly spaced on the surface of the container  100 , to make it convenient to hold onto the container  100  when it is being used, so that the container  100  stays in place, and the user can use the other hand to activate the pull rod member  230 , to operate the food processor. Furthermore, with the two concave regions  112 , the user can switch hands to operate, leading to higher efficiency in processing the food. In this embodiment, the two concave regions  112  becomes a concave region inside the container  100 , these concave region  112  in a way increases the friction to the food being processed inside the container  100 . The said four convex elements  111  can be divided into two groups; each group includes two of the convex elements, the convex elements of each group uses the concave region  112  as the center to space evenly apart, that is the two convex elements are evenly spaced on either side of the each concave region  112 .
