[0026] Reference Figure 3 - Figure 5 The cleaning component includes a suction fan 13, which is fixedly connected to the rear end of the workbench 1, and a dust suction pipe 14 is fixedly connected to the top of the suction fan 13. A collection box 15 is slidably connected inside the workbench 1, and two card slots 17 are provided at the rear end of the collection box 15. Two card blocks 19 are slidably connected inside the workbench 1, and the two card blocks 19 are respectively clamped in the two card slots 17. The rear ends of the two card blocks 19 are fixedly connected to pull rods 20, and the outer circumferences of the two pull rods 20 are both sleeved with springs 21. Two limit slots 1 are provided inside the workbench 1. 8. The two clamping blocks 19 and the two pull rods 20 are respectively slidably connected inside the two limit grooves 18.

[0027] Specifically, the suction fan 13 is fixedly connected to the rear end of the workbench 1, and is used to suck the waste generated during processing into the collection box 15 through the chip suction pipe 14. Slots 17 are set on both sides of the collection box 15, which are used to insert the block 19 into the slot 17 to fix the collection box 15 inside the workbench 1.

[0028] Working principle: when it is necessary to fix the polycrystalline diamond composite sheet, the starting motor 7 drives the threaded rod 8 to rotate, so that the moving block 9 drives the slider 2 10 to move, thereby driving the rotating frame 2 to move through the driving rod 11, thereby driving the four sliders 1 5 to move. When the slider 1 5 moves, the four baffle rods 4 are driven to move around the rotating rod 3 respectively, so that the baffle 6 at the other end of the baffle rod 4 clamps the polycrystalline diamond composite sheet. When it is necessary to release the clamping of the polycrystalline diamond composite sheet, the driving motor 7 is reversed to reverse the rotating frame 2, so that the baffle 6 no longer clamps the polycrystalline diamond composite sheet.

[0029] When it is necessary to clean the waste chips, the vacuum fan 13 is started to suck the waste generated during processing into the collection box 15 through the chip suction pipe 14. When cleaning the waste chips inside the collection box 15, the handle 23 is pulled to drive the pull rod 20 to move. The pull rod 20 will pull the block 19 out of the slot 17, so that the collection box 15 loses its restraint. The collection box 15 can be removed for cleaning by pulling the handle 16. When installing the collection box 15, first pull the handle 23 to make the block 19 enter the limit slot 18, install the collection box 15 back to its original position, release the force on the handle 23, and the spring 21 releases the tension to clamp the block 19 into the slot 17, and the installation is completed.
