[0032] In an alternative embodiment, sliding rods 44 that slide up and down are provided on the left support block 42 and the right support block 43 through through holes. A limit disk 45 is fixed to the top of the sliding rods 44. A transparent limit cover 46 is fixedly arranged between the bottom ends of the two sliding rods 44. The transparent limit cover 46 is connected to the dust collector 41 through a hose 47.

[0033] In this embodiment: The drilling area is covered by the transparent limit cover 46, and then the dust collector 41 is started to adsorb the debris inside the transparent limit cover 46 through the hose 47.

[0034] In an alternative embodiment, the pressing component 2 includes a T-shaped support 21 fixed on the top of the processing support 1. A pair of guide rods 22 and a cylinder 23 are arranged on the top of the T-shaped support 21. A moving seat 24 is sleeved on the two guide rods 22. The top end of the piston rod of the cylinder 23 is fixedly connected to the bottom of the moving seat 24. A return spring 25 is sleeved on the guide rod 22 at the bottom of the moving seat 24.

[0035] In this embodiment: The cylinder 23 moves to drive the moving seat 24 to slide downwards on the guide rod 22 and compress the return spring 25, and finally drive the drilling mechanism 3 and the transparent limit cover 46 to move downwards.

[0036] In an alternative embodiment, the drilling mechanism 3 includes a motor support 31 fixed on the moving seat 24, and a rotating shaft movably arranged on the moving seat 24. A motor 32 is installed on the motor support 31. A driving wheel 33 is fixed to the output end of the motor 32. A driven wheel 34 is fixed to the top end of the rotating shaft.

[0038] The working principle of the present utility model:

[0039] The driving wheel 33 is driven to rotate by the motor 32. The driving wheel 33 drives the driven wheel 34 to rotate through the belt 37, thereby driving the drill bit 36 on the drill chuck 35 to rotate. Then, the moving seat 24 is driven to slide downward on the guide rod 22 by the movement of the cylinder 23, and the return spring 25 is compressed. Finally, the drilling mechanism 3 and the transparent limit cover 46 are driven to move downward. The transparent limit cover 46 first fits with the plastic part, and the slide rod 44 is pushed to slide upward in the through holes of the left support block 42 and the right support block 43, and the spring sleeved around its outer periphery is compressed. Then, the dust collector 41 is started to adsorb the debris inside the transparent limit cover 46 through the hose 47, preventing the debris from being inhaled into the lungs by the human body and ensuring the physical health of the workers.
