The clamping mechanism 4 includes a first screw 401 rotatably connected to one side of the connecting plate, a movable sleeve 402 is screwed to the outer wall of the first screw 401, a limiting plate is fixed to the top end of the pushing plate 301, the movable sleeve 402 is slidably connected to the limiting plate, and a mounting plate 403 is fixed to the end of the movable sleeve 402 away from the first screw 401, and a clamping plate 404 is installed on the side of the mounting plate 403 away from the movable sleeve 402.

[0021] It should be noted that the turntable 302 is driven to rotate by the first motor 305, and the rotation of the turntable 302 drives the moving block 304 to move, thereby moving the pushing plate 301, which can move the connecting plate and drive the clamping mechanism 4 to move, so that the overall size of the device can be adjusted, which is more practical. In addition, by rotating the first screw 401, the first screw 401 rotates to drive the moving sleeve 402 to move, and the movement of the moving sleeve 402 drives the mounting plate 403 to move, which can drive the clamping plate 404 to move, so that the workpiece can be clamped between multiple clamping plates 404.

[0022] like Figure 1 、 Figure 3 and Figure 4As shown, a fixed plate 9 is fixed to the bottom end of the push plate 301. A rotating sleeve 8 is rotatably connected to the adjacent sides of the two opposing fixed plates 9. A rotating rod 7 is inserted between the two rotating sleeves 8. A limit bar is fixed to the outer wall of the rotating rod 7, and the inner wall of the rotating sleeve 8 is adapted to the rotating rod 7 and the limit bar. After the rotating sleeve 8 passes through the fixed plate 9, a first rotating wheel 11 is fixed to its outer wall. After the first screw 401 passes through the connecting plate, a second rotating wheel 12 is fixed to its outer wall. A belt 10 is provided between the first rotating wheel 11 and the second rotating wheel 12. A fixed frame is fixed to the other side of one of the two opposing fixed plates 9.

A plurality of support legs 2 are mounted at the bottom end of the workbench 1.

[0023] It should be noted that the second motor is started by the controller 6, and the second motor drives the rotating sleeve 8 to rotate. The rotation of the rotating sleeve 8 causes the first rotating wheel 11 to rotate, and the rotation of the first rotating wheel 11 drives the rotating rod 7 to rotate, so that the rotating sleeve 8 opposite thereto can be rotated, so that the relative first rotating wheel 11 rotates to drive the belt 10 to move, and the movement of the belt 10 drives the second rotating wheel 12 to rotate, and the rotation of the second rotating wheel 12 drives the first screw 401 to rotate.

[0024] Working principle: The first motor 305 is started by the controller 6, and the first motor 305 drives the turntable 302 to rotate. The rotation of the turntable 302 drives the moving block 304 to move, thereby moving the pushing plate 301, which can move the connecting plate and drive the clamping mechanism 4 to move. In this way, the overall size of the device can be adjusted, which is more practical. In addition, by rotating the first screw 401, the first screw 401 rotates to drive the moving sleeve 402 to move, and the movement of the moving sleeve 402 drives the mounting plate 403 to move, which can drive the clamping plate 404 to move, so that the workpiece can be clamped between multiple clamping plates 404. When the pushing plate 301 moves, the rotating sleeve 8 slides on the outer wall of the rotating rod 7.

[0025] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is limited by the accompanying embodiments and their equivalents.
