FIELD OF THE INVENTION 
     The present invention relates generally to a work box, and more particularly to a multifunctional work box which can be used as a workbench, a workpiece holder, a tool container, etc. 
     BACKGROUND OF THE INVENTION 
     The conventional workbench is limited in design in that it can not be used as a tool container. Similarly, the conventional tool box is designed simply for keeping the tool; it is not provided with means enabling it to be used as a workbench, a workpiece holder, and so forth. In addition, the conventional workbench or tool box can not be carried around easily. 
     SUMMARY OF THE INVENTION 
     The primary objective of the present invention is to provide a multifunctional work box which is designed for use as a tool box, a workbench, a workpiece holder, etc. 
     It is another objective of the present invention to provide a multifunctional work box which can be easily carried around. 
     In keeping with the principle of the present invention, the foregoing objectives of the present invention are attained by a multifunctional work box comprising a base and a face board pivoted to the top of the base. The base is provided with a receiving compartment having an open top. The face board may be used as a workbench. The face board is provided on the upper surface thereof with a cutting auxiliary device, and in the underside thereof with a clamp for holding a workpiece.

     DETAILED DESCRIPTION OF THE INVENTION 
     As shown in all drawings provided herewith, a work box  10  embodied in the present invention comprises a base  20 , a face board  40 , a cutting auxiliary device  50 , and a clamp  60 . 
     The base  20  has a receiving compartment with an open top  21 . The compartment is provided in the front side wall thereof with a front opening  22  via which a drawer  23  is received in the compartment. The drawer  23  is intended to contain tools and articles. The compartment is provided in the bottom edge of the front side wall thereof and the bottom edge of the rear side wall thereof with a locating plate  24  which is provided with two through holes  241 . The work box  10  can be thus fastened on a workbench by a plurality of fastening bolts, which are received in the through holes  241  of the two locating plates  24 . The compartment of the base  20  is further provided in the left side wall thereof and the right side wall thereof with a saw receiver  25  of a U-shaped cross section for keeping a rough saw  251  and a finishing saw  252 . The base  20  is further provided in the left and the right side wall thereof with a handle  26  to facilitate the holding and the moving of the work box  10  with the hands. 
     The face board  40  is of a rectangular construction and is disposed in the open top  21  of the compartment of the base  20 . The face board  40  is provided at the center of two short sides thereof with a pivot  42 . The base  20  is provided with two pivot slots  28  corresponding in location to the two pivots  42  of the face board  40 . The face board  40  is fastened pivotally with the base  20  by the pivots  42  which are received in the pivot slots  28 . The compartment of the base  20  is covered by the face board  40 . The face board  40  is provided respectively in two short sides thereof with a retaining pillar  44  which is separated from the pivot  42  by a predetermined distance. The base  20  is provided in the top end thereof with four retaining slots  29  corresponding in location to the retaining pillars  44 . When the upper surface  401  or the underside  402  of the face board  40  faces upward, the retaining pillars  44  are received in the retaining slots  29  so as to locate the face board  40 . The base  20  is further provided in the top end thereof with two retaining pieces  30  fastened pivotally therewith such that the retaining pieces  30  can be swiveled to engage the upper surface of the face board  40  so as to fix the face board  40  which is used as a workbench platform. 
     The cutting auxiliary device  50  comprises a rectangular bottom plate  51  which is disposed on the upper surface  401  of the face board  40 , and two side plates  52  extending upright from two sides of the bottom plate  51 , thereby resulting in the formation of the cutting space  53  which is defined by the bottom plate  51  and the side plates  52  and is intended to accommodate a workpiece. The two side plates  52  are provided with six tangent slots  54 , which are formed in pair and in six sets, with two tangent slots  54  of any one set being coplanar for receiving a saw blade. The saw blade is capable of working on a workpiece in various angles. 
     The clamp  60  comprises an outer clamp body  61 , an inner clamp body  66 , and a threaded rod  68 . The outer clamp body  61  is formed of a bottom plate  62  which is disposed in the underside  402  of the face board  40 , two clamping plates  63  forming therebetween an angle of 90 degrees and extending upright from the bottom plate  62 , and a threaded rod seat  64  disposed on the bottom plate  62  for setting up the threaded rod  68 . The inner clamp body  66  has two clamping surfaces  67  parallel to the two clamping plates  63  of the outer clamp body  61 . The inner clamp body  66  is connected with one end of the threaded rod and is driven by the threaded rod to displace toward the two clamping plates  63 . A workpiece  69  is therefore held securely in place by the inner clamp body  66  and the outer clamp body  61 . 
     The drawer  23  of the base  20  is provided in the top thereof with a tray  32  for collecting the minute particles, such as sawdust. The base  20  is provided in two sides of the top thereof with a metric scale  34  and a British scale  35  for measuring the length of the workpiece. 
     The face board  40  may be provided with another cutting auxiliary device  80  as shown in FIG. 7, or an angle gauge, in place of the cutting auxiliary device  50  and the clamp  60 .
A multifunctional work box comprises a base and a face board pivoted to the top of the base. The base has a receiving compartment with an opening facing upward. The compartment is intended to keep hand tools. The face board is used to cover the compartment and to serve as a workpiece platform. The face board can be swiveled to enable its underside to face upward.
