The docking cover 14 is threadedly connected with the end of the first rigid tube 11. A first filter screen 15 is clamped inside the docking cover 14. The top of the first filter screen 15 is mutually attached to the end of the first rigid tube 11. The bottom of the first filter screen 15 is located inside the bellows 13.

[0026] A handle 23 is fixed to one end of the casing 1. An anti-slip sleeve is fixed to the outer wall of the handle 23, which is beneficial for the operator to hold and use.

[0027] A control button 22 is fixed to the top of the casing 1.

[0031] Working principle: When using this clamp sleeve weld grinding tool, first insert the plug 25 into the socket, then press the control button 22 to make the motor 2 powered on. Then the motor 2 drives the first bevel gear 4 to rotate through the first rotating shaft 3. Then the first bevel gear 4 drives the grinding disc 7 to rotate through the second bevel gear 6 and the second rotating shaft 5, so as to be able to grind the clamp sleeve weld;

[0032] When the first bevel gear 4 drives the second bevel gear 6 to rotate, the second bevel gear 6 can also drive the third bevel gear 17 to rotate. Then, the third bevel gear 17 drives the fan blade 18 to rotate through the third rotating shaft 16, so that the gas inside the second fixed cover 12 is discharged through the second rigid tube 19, making the inside of the second fixed cover 12 in a negative pressure state. Under the action of the pressure difference, the outside air and the dust generated by grinding enter the inside of the inner cavity 9 through the dust suction holes 10. Then, the air enters the inside of the second fixed cover 12 through the first rigid tube 11 and the corrugated tube 13, and is finally discharged through the second rigid tube 19, and the dust in the air is filtered by the first filter screen 15;

[0033] When the dust inside the first filter screen 15 needs to be cleaned, rotate the docking cover 14. Since the docking cover 14 is threadedly connected to the first rigid tube 11, the docking cover 14 and the first rigid tube 11 are separated, and the first filter screen 15 can be poured out from the inside of the docking cover 14 for cleaning.
