     Via above design, the stopper  14  would be brought to swing by pressing the pushing button  92  of the pushing member  9  for letting the last tableware  5  trapped by the stopper  14  to slide out for facilitating the user to take it out. Meanwhile, the pushing rod  91  of the pushing member  9  pulls the tableware  5  in the bottommost layer to displace and fall onto the inclined chute  19  arranged below. Then the fallen tableware  5  in the bottommost layer slides to the tableware takeout outlet  100  and is trapped by the stopper  14 . In such a way, a next automatic taking out cycle is prepared. 
     It should be noted that, in the embodiment 2, the detachable magazine  3  in the embodiment 1 also can be employed. Meanwhile, the first adjusting and stopping block  10  and the second adjusting and stopping block  4  in embodiment 1 also can be mounted in the embodiment 2. In additional, the fixedly mounted magazine  3  in the embodiment 2 also can be employed in the embodiment 1. 
     Embodiment 3 
     The present embodiment is different from the embodiment 1 or 2 in follows. As shown in  FIG. 9 , the stopping plate  14   b  of the stopper  14  is located at a position where the handle  5   b  of the tableware  5  stays after sliding along the inclined chute  19 , that is, being approximately close to the tail end of the inclined chute  19  arranged below. A rotating structure  60  is provided on one side of the stopping plate  14   b  facing the inclined chute  19  for preventing the tableware  5  from returning during its pulling out. The rotating structure  60  can be arranged at the tail end of the inclined chute  19  arranged below or between the tail end of the inclined chute  19  arranged below and the stopping plate  14   b  of the stopper  14 . 
     The rotating structure  60  comprises a rotatable holding member  601  for holding the food taking part  5   a  of the tableware  5  and an inserting hole  602  for passing through the handle  5   b  of the tableware  5 . The rotatable holding member  601  only rotates toward a direction of the stopping plate  14   b  and resets along the way it comes. A block  603  for preventing the rotatable holding member  601  from rotating in a direction deviating from the stopping plate  14   b  is arranged on one side of the rotatable holding member  601  deviating from the stopping plate  14   b.    
     In this embodiment, there are two rotatable holding members  601  arranged separately at opposite directions for forming the inserting hole  602 . The two rotatable holding members  601  are rotatably arranged via the rotation shaft  604  respectively. In other embodiments, there can be only one rotatable holding member  601  with the inserting hole  602  opened therewith and the rotatable holding member  601  can also be rotatably arranged via the rotation shaft  604 . 
     In the process of taking the tableware  5  out, the stopper  14  would bring the pushing member  9  to move, so as to push the tableware  5  in the bottommost layer to fall off, there is a possibility that the tableware  5  is not completely removed, and the user will push the tableware  5  back toward the inclined chute  19 . Then, in the process of taking the tableware  5  out again, the tableware  5  may fall again, which results in the falling of a plurality of tableware  5 . However, in the present application, such situation can be avoided by designing a rotating mechanism  60  that rotates only in the direction facing the stopper  14 . 
     Embodiment 4 
     The present embodiment is different from the embodiment 1, 2 or 3 in follows. As shown in  FIGS. 9-10 , a lower surface of the pushing portion  9   a  of the pushing member  9  is provided with a receiving member  70  for receiving the handle  5   b  of the tableware  5  which is displaced. The receiving member  70  and the pushing member  9  move synchronously with respect to the first bearing block  8 . One end of the receiving member  70  is connected with the lower surface of the pushing portion  9   a  via a connecting piece  701 . The other end of the receiving member  70  is a receiving portion  702  formed by projecting relative to an end portion of the pushing portion  9   a . A movement space  703  for a displacement relative to the first bearing block  8  is formed between the lower surface of the pushing portion  9   a  and an upper surface of the receiving member  70 . 
     In the present embodiment of the present application, a penetrating hole  704  is provided on the first bearing block  8  for passing through the receiving member  70 , while the receiving portion  702  of the receiving member  70  is inserted into the penetrating hole  704 . Accordingly, the pushing portion  9   a  moves along the upper surface of the first bearing block  8 , while the receiving member  70  moves along a hole wall of the penetrating hole  704  during the movement. 
     In the other embodiment, the receiving member  70  is located at a lower surface of the first bearing block  8 , and the clearance space between the lower surface of the pushing portion  9   a  and the upper surface of the receiving member  70  along the longitudinal direction approximately matches the thickness of the first bearing block  8 . The pushing portion  9   a  moves along the upper surface of the first bearing block  8 , while the receiving member  70  moves along the lower surface of the first bearing block  8 . 
     After bringing the pushing member  9  to pushing the tableware  5  in the bottommost layer to fall off by the stopper  14 , the handle  5   b  of the tableware  5  would fall onto the receiving portion  702  of the receiving member  70 , rather than fall off immediately. When the stopper  14  and the pushing member  9  are reset, the receiving member  70  would also be reset to withdraw back and then the tableware  5  falling onto the receiving portion  702  of the receiving member  70 , would fall off really. In such a way, the situation of the falling of a plurality of tableware  5  would be avoided similarly. 
     Embodiment 5 
     The present embodiment is different from the embodiment 1, 2, 3 or 4 in follows. As shown in  FIGS. 9, 11 and 12 , a prompter  80  for indicating whether the tableware  5  is about to be used up is installed at a side end of the magazine  3 . 
     The prompter  80  comprises a rotating member  801  which automatically rebounds after rotation, such as through a torsion spring. The rotating member  801  is provided with a pressing handle  802  formed by protruding upward from the rotating member  801  for rotating by pressing the stacked tableware  5 . The rotating member  801  is provided with a first indication layer  810  for indicating that the tableware  5  is sufficient and a second indication layer  820  for indicating that the tableware  5  is about to be used up at its outer circumferential surface. The rotating member  801  is mounted in a frame body  830 , whose outer side is arranged with a display port  803  for displaying the first indication layer  810  and the second indication layer  820 . The display port  803  can also be provided with a perspective window. The first indication layer  810  and the second indication layer  820  may be ink layers of different colors formed by coating or pattern layers formed by etching. In one embodiment of the present application, one end of the first indication layer  810  is connected with one end of the second indication layer  820 . In another embodiment of the present application, there can be separated distance between the first indication layer  810  and the second indication layer  820 . 
     As long as the pressing handle  802  is pressed to rotate through the stacked tableware  5 , the first indication layer  810  is displayed by the display port  803 . When the stacked tableware  5  is about to be used out, the pressing handle  802  would automatically rebound, such that the second indication layer  820  is displayed by the display port  803 . 
     Whether the stacked tableware  5  is about to be used out can be shown by the prompter  80 , such that the tableware  5  can be supplemented into the magazine  3  whenever necessary. 
     Embodiment 6 
     The present embodiment is different from the embodiment 1-5 in follows. As shown in  FIG. 9 , the housing body  1  is mounted with at least one sliding body  30  on which the magazine  3 , the support assembly  678 , the inclined chute  19 , the pushing member  9  and the stopper  14  are formed on each sliding body  30 . Moreover, a bottom end of each sliding body  30  is slidably connected with the housing body  1  via a sliding mechanism  40 . 
     In the present embodiment of the present application, the sliding mechanism  40  comprises a guide rail  401  formed at a bottom side of the housing body  1  and a sliding groove  301  formed at the bottom end of the sliding body  30 . At least one pulley  402  is installed on both sides of the guide rail  401 , and moves along the sliding groove  301 . There can be one or more pulley  402  on both sides of the guide rail  401 , which depends on the actual requirements. 
     It should be noted that the sliding mechanism  40  shown in  FIG. 9  is only schematic, as long as the sliding mechanism  40  can make the sliding body  30  sliding, it falls into within the protection scope of the present application. 
     Through the above design, the sliding body  30  can be freely slidden out and installed to supplement the new tableware  5  or for maintaining. 
     Embodiment 7 
     The present embodiment is different from the embodiment 1-6 in follows. As shown in  FIG. 9 , a stopping blocking member  710  provided for preventing the tableware  5  from turning around is arranged above the inclined chute  19 . Through this design, the turning of the tableware  5 , especially the knife in the inclined chute  19  is avoided. The food taking part  5   a  of the tableware  5  may not be hold by the stopping plate  14   b  of the stopper  14 , but passes through the recess hole  14   c  and/or the inserting hole  602  of the rotating structure  60 , which results in that the tableware  5  in the magazine  3  may not fall off. 
     The self-service device for taking tableware according to the present application has a neat appearance, and can be operated and taken out in a hermetically sealed environment, so the tableware is clean and hygienic. Furthermore, just one piece of tableware can be taken out for one time, and the receiving and taking out of the tableware is very portable and quick, thus the usage of the self-service device for taking tableware is economical and environmental protected.
