The bottoms of the two first positioning plates 6 are fixedly connected with movable blocks 24. The two movable blocks 24 are slidably installed in the movable grooves 10 opened on the positioning platform 3. The bottom of the movable block 24 is fixedly connected with the movable plate 7. The two movable plates 7 are provided with a fixed side plate 25 on the side away from each other. The fixed side plate 25 is fixedly connected to the bottom of the positioning platform 3. The first double-ended screw 8 is rotatably connected between the two fixed side plates 25. The two ends of the first double-ended screw 8 respectively pass through the two movable plates 7 and are respectively connected to the two movable plates 7 by threaded cooperation. The side wall of the fixed side plate 25 is also rotatably connected with a rotating handle 9, and the rotating handle 9 is fixedly connected to the first double-ended screw 8.

[0022] When in use, the rotating handle 9 is rotated to drive the first double-headed screw 8 to rotate, thereby controlling the distance between the two movable plates 7 and further controlling the distance between the two first positioning plates 6 .

[0023] The positioning table 3 is fixedly connected to the processing table 2 by a plurality of fixing bolts. The upper surface of the processing table 2 is provided with a receiving groove 4 for accommodating the first adjustment component. The upper surface of the processing table 2 is also provided with a receiving side groove 5 for accommodating the rotating handle 9.

[0024] The first adjustment assembly can be stored through the storage groove 4, and the rotating handle 9 can be stored through the storage side groove 5.

[0025] Both sides of the bottom of the first positioning plate 6 are fixedly connected with guide blocks 22 , and both ends of the positioning platform 3 are provided with guide grooves 23 , which are slidably engaged with the guide blocks 22 .

[0026] The guide block 22 and the guide groove 23 can make the first positioning plate 6 move more stably.

The bottom of the two second positioning plates 11 are fixedly connected with the slider 15. The two sliders 15 are slidably installed in the slide groove 12 opened on the upper surface of the positioning platform 3. The second double-headed screw 13 is rotatably connected in the slide groove 12. The second double-headed screw 13 passes through the two sliders 15 and the two ends are respectively connected to the two sliders 15 by threaded cooperation. The side wall of the positioning platform 3 is rotatably connected with an adjusting piece 14, and the adjusting piece 14 is fixedly connected to the second double-headed screw 13.

[0028] When in use, the adjusting member 14 is rotated to drive the second double-ended screw 13 to rotate, thereby controlling the distance between the two sliders 15 and further controlling the distance between the two second positioning plates 11 .

The locking bolt 21 penetrates the fixed cross plate 17 and is connected to the fixed cross plate 17 by threaded cooperation.

[0030] When in use, after the metal part is fixed by the two first positioning plates 6, the locking bolt 21 is rotated to move the locking bolt 21 downward. The bottom of the locking bolt 21 will contact the clamping plate 16 and drive the clamping plate 16 to move downward, thereby clamping the upper end of the metal part. At this time, the reset spring 19 will be stretched. When the metal part needs to be removed, the locking bolt 21 is rotated in the opposite direction. Under the action of the restoring deformation of the reset spring 19, the clamping plate 16 will move upward and return to its initial position.

[0031] The bottom of the clamping plate 16 is frosted.

[0032] Such an arrangement can increase the friction between the clamping plate 16 and the metal part.
