BACKGROUND OF THE INVENTION 
   1. Field of the Invention 
   The present invention relates to a cutting apparatus, and more particularly to a multipurpose cutting apparatus comprising a cutting table, a straight cutter, a multipurpose cutter and two adjusting assemblies. 
   2. Description of the Prior Arts 
   A conventional paper cutter sold on the market generally comprises a cutting table and a straight cutter which is moveable on the rail of the cutting table. The cutting strength of this conventional paper cutter is great, however, the straight cutter is only able to cut the paper in straight lines, and the user has to use other cutters if when a curve line is required to made. Thus, the applicability of the conventional paper cutter is limited. 
   The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.

   DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
   Referring to  FIGS. 1–4 , a multipurpose cutting apparatus in accordance with a preferred embodiment of the present invention is shown and comprises: a cutting table  10 , a straight cutter  20 , two adjusting assemblies  30 , a second rail  40  and a multipurpose cutter  50 . 
   The cutting table  10  is oblong-shaped is provided at either end thereof with a rail seat  11 , and a first rail  12  disposed between the two rail seats  11 . At both ends of the cutting table  10  opposite the two rail seats  11  are provided a pair of lateral-slide grooves  13 , respectively. A positioning groove  131  is formed between each pair of the lateral-slide grooves  13 . On the surface of the cutting table  10  is provided a cutting pad  60  which is made of cut-resistant material and located between the two pairs of lateral-slide grooves  13 . A plurality of through holes  61  are formed on the cutting table  10  in response to the cutting pad  60 , and a chamber  14  is formed at a side of the cutting table  10  for storage of cutter blades. 
   The straight cutter  20  is movably and detachably mounted on the first rail  12  of the cutting table  10  to cut the objects (such as: paper, film, and etc) in straight line, and the straight cutter  20  can be dissembled from the first rail  12  by removing the fixing member  21 . 
   The two adjusting assemblies  30  are fixed in the lateral-slide grooves  13  of the cutting table  10 , respectively, and each of the adjusting assemblies  30  comprises a base  31 , a slide member  32 , a positioning member  33  and a nut  34 . 
   The slide member  32  has a reverse U-shaped leg  321  slidably engaged in the lateral-slide grooves  13 , and a locking end  324  of the reverse U-shaped leg  321  is located at the bottom of the lateral-slide grooves  13 . A vertical positioning hole  322  and a horizontal pivot hole  323  are formed in the slide member  32 , respectively. 
   The positioning member  33  is screwed with the nut  34  after passing through the vertical positioning hole  322  of the slide member  32  and the positioning groove  131  of the cutting table  10 , so as to control the movement of the slide member  32 . 
   The base  31  is provided at an end thereof with a horizontal pin  311  which is inserted in the horizontal hole  323  of the slide member  32 , and is further provided with a horizontal projection  312 . The horizontal projections  312  of the bases  31  of the two adjusting assemblies  30  are located opposite each other. 
   The second rail  40  is disposed between the horizontal projections  312  of the bases  31  of the two adjusting assemblies  30 , and is provided in the direction of the surface of the cutting table  10  with an antiskid unit, such as sponge (not shown). 
   The multipurpose cutter  50  includes a housing  51 , a cover  52 , a shaft  53 , a cutter blade  54 , an elastic member  55  and a lateral cover  56 . The housing  51  is slideably mounted on the second rail  40 , and the cutter blade  54  can be replaced at any time according to the user&#39;s needs. 
   For a better understanding of the invention, its operating advantages and specific objects attained by its uses, reference should be made to  FIG. 5 . 
   To use the straight cutter  20 , the user can rotate the base  31  of the adjusting assemblies  30  about the slide member  32 , so as to cause the second rail  40  move upward. Meanwhile, the multipurpose cutter  50  is raised upward, and the cutter blade  54  is turned around to face upward. At this moment, the object to be cut (such as paper, film) can be inserted to the cutting table through the space under the multipurpose cutter  50 , so as to be cut in straight lines by the straight cutter  20  on the first rail  12 . 
   To use the multipurpose cutter  50 , the user only needs to change the cutter blade  54 , and then to lower down the multipurpose cutter  50  by adjusting the base  31 , so that different cutting lines (such as: wave cut line, all kinds of laces, perforated line, and etc) can be carried out by using different cutter blades  50 . 
   After the multipurpose cutter  50  is turned upward by using the base  31  of the adjusting assemblies  30 , the cutting pad  60  will be cleared automatically, furthermore, the user is able to remove the lateral cover  56  and replace the cutter blade  54  easily. 
   To adjust the multipurpose cutter  50 , the positioning member  33  of the adjusting assemblies  30  can be loosened relative to the nut  34 , so as to allow the π-shaped leg  321  of the slide member  32  to move along the two lateral-slide grooves  13  (the locking end  324  of the slide member  32  can stabilize the adjusting assemblies  30 ). After the slide member  32  pushes the second rail  40  to a predetermined position, the user can tighten the positioning member  33  relative to the nut  34 , so as to re-fix the second rail  40 . By this way, the multipurpose cutter  50  can be adjusted quickly and easily. 
   It will be noted that the straight cutter  20  and the multipurpose cutter  50  are disposed at both sides of the cutting table  10 , respectively, and the multipurpose cutter  50  can be adjusted flexibly, so as to improve the flexibility of the cutter to produce more different sized products. 
   The adjusting assemblies  30  can enable the multipurpose cutter  50  to be adjusted more flexibly, and the cutting pad  60  is large enough for enabling the object to be cut into different sizes, and the through holes  61  are designed to enable the user to remove the cutting pad  60  by inserting fingers through the through holes  61 . 
   Referring to  FIG. 6 , which shows a multipurpose cutting apparatus in accordance with another embodiment of the present invention, the multipurpose cutting apparatus of this embodiment is generally similar with that of the first embodiment, and the difference is that each of the bases  31  of the two slide assemblies  30  in this embodiment is provided with a locking bolt  313  which is sized in response to the size of the positioning groove  131  of the cutting table  10 , and the locking bolt  313  is inserted in the positioning groove  131 . This locking bolt  313  is designed to enable the base  31  of the two adjusting members  30  to be positioned in the positioning groove  131  more stably (enabling the second rail  40  to be positioned firmly), so that the multipurpose cutter  50  can be prevented from oscillation during operation, thus improving the processing effect. 
   It is to be noted that the second rail  40  also can be disassembled easily. 
   While we have shown and described various embodiments in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
