In practical application, the first through groove 13 and the second through groove 14 are preferably set to be V-shaped grooves, which is easy to implement.

In this embodiment, as shown in fig. 3, as mentioned above, the bench clamp further includes a supporting seat 6 and a driving assembly, the supporting seat 6 is screwed on the base 1, the supporting seat 6 is located on the other side of the movable clamp body 3 relative to the side where the movable jaw 5 is located, and the supporting seat 6 and the movable clamp body 3 are spaced apart from each other. The driving assembly comprises a screw rod 7 penetrating through the supporting seat 6, one end of the screw rod 7 is rotatably connected with the movable clamp body 3, the other end of the screw rod 7 is provided with an operating part 8, and the screw rod 7 is in threaded fit with the supporting seat 6. Of course, one end of the screw 7 is rotatably connected to the movable clamp body 3, and reference may be made to the structure of the rotary connection in the prior art, which will not be described again.

In addition, in the present embodiment, as shown in fig. 1 to 4, the vise further includes a protrusion 9, the protrusion 9 is formed on two sides of the base 1 along the sliding path of the movable vise body 3, and correspondingly, a through groove 301 for passing through the two protrusions 9 is formed on the movable vise body 3, and the protrusion 9 and the through groove 301 are in clearance fit. As a further setting, the top of the protruding portion 9 is provided with a chamfer 900, so as to be beneficial to increasing the gap between the protruding portion 9 and the penetrating groove 301, reduce the influence on the movable clamp body 3 after the protruding portion 9 is damaged, and meanwhile, if a workpiece is placed or falls onto the protruding portion 9, the chamfer 900 can reduce the damage degree of the protruding portion 9 and the workpiece to a certain extent.

For improving the whole use effect of the bench clamp, as shown in fig. 5, corresponding to the protruding part 9, an adapting groove 600 adapted to the cross section of the protruding part 9 is arranged on the supporting seat 6, the protruding part 9 is inserted in the adapting groove 600 to form a butt connection between the protruding part 9 and the supporting seat 6, when the bench clamp is used for clamping a workpiece, the force is favorably transmitted between the protruding part 9 and the supporting seat 6, and the whole stability of the bench clamp is favorably realized to a certain extent. And a chamfer 900 is provided at the insertion end of the boss 9 to facilitate the cooperation between the boss 9 and the support seat 6. Wherein the chamfer 900 arrangement of the insertion section is not explicitly shown in the figures; and the adapting groove 600 is opened on one side of the supporting seat 6 facing the convex part 9, and is not arranged through the supporting seat 6.

When the bench clamp for student practice in the embodiment is used, the screw 7 is controlled by driving the operation part 8, the distance between the movable jaw 5 and the fixed jaw 4 is increased to accommodate a workpiece to be clamped through the relative movement of the screw 7 and the supporting seat 6, and then the operation part 8 is driven reversely to enable the movable jaw 5 to be close to the fixed jaw 4, so that the workpiece is fixedly clamped. In this process, if the workpiece falls off due to stable clamping, due to the arrangement of the protruding portion 9, the workpiece can be prevented from being in hard contact with the guide sliding surface of the movable clamp body 3, thereby ensuring stable use of the bench clamp.

When the movable jaw 5 needs to be replaced, the screw connection relationship between the movable jaw 5 and the movable clamp body 3 is firstly released, then external force is applied to slide and draw out the movable jaw 5 along the direction of the mounting groove 11, so that the movable jaw 5 and the movable clamp body 3 are detached, and if the movable jaw 5 needs to be mounted on the movable clamp body 3, the reverse operation is performed. Of course, the procedure for replacing the fixed jaw 4 is the same as that for replacing the movable jaw 5, and will not be described again.

In the bench clamp for student practice, the protrusions 9 are arranged on the two sides of the base 1 through the sliding path along the movable clamp body 3, so that the bench clamp can support a workpiece to be clamped, and the workpiece is prevented from being in hard contact with the main guiding matching surface of the movable clamp body 3, so that the matching surface is damaged, and the working precision and the good using effect of the bench clamp can be guaranteed. Simultaneously, the fixed jaw 4 and the movable jaw 5 are detachably mounted on the fixed jaw body 2 and the movable jaw body 3 respectively, and the supporting seat 6 is screwed on the base 1, so that the fixed jaw 4 and the movable jaw 5 are convenient to disassemble and assemble, and the maintenance and the replacement are facilitated.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
