[0030] It should be noted that when the staff needs to control the grinding depth of the workpiece, first, the power mechanism 3 can drive the grinding disc 6 to operate normally, and at the same time rotate the rotating rod 71. When the rotating rod 71 rotates, it can drive the connecting tube 9 to move, and then the movement of the connecting tube 9 can drive the first gear 75 to rotate. When the first gear 75 rotates, it drives the second gear 8 to rotate, so that under the action of the second gear 8, the rotating tube 73 can be driven to rotate, and then the rotating tube 73 can drive the moving rod 74 to move, and then the moving rod 74 can drive the power mechanism 3 to move, and when the power mechanism 3 moves, it drives the sliding rod 11 to slide inside the fixed tube 10, so that the power mechanism 3 and the grinding disc 6 can be driven to operate normally.

[0034] A second bolt 23 is provided inside the rear cover 2 , and the outer side of the second bolt 23 is threadedly connected to the inner side of the handle 1 .

[0035] It should be noted that: when the staff needs to disassemble the power mechanism 3 and the sliding block 72, they first rotate the first bolt 22 so that the first bolt 22 is disengaged from the first screw hole 20 and the second screw hole 21, and then under the action of the second spring 16, the sliding block 72 can be driven to move through the top plate 17, so that the sliding block 72 can be inside the handle 1, and then the power mechanism 3 is pulled, and the sliding block 72 and the power mechanism 3 can be disassembled.

[0036] refer to Figure 1 and Figure 5 As shown, a third clamping block 24 is fixedly connected to the outer side of the bottom rod 5 , and a chuck 26 is fixedly connected to the top of the grinding disc 6 .

[0037] A third bolt 25 is provided inside the chuck 26 , and a third clamping groove 27 for use with the third clamping block 24 is provided inside the chuck 26 .

[0038] It should be noted that: when the grinding disc 6 needs to be disassembled, the third bolt 25 is first rotated so that the third bolt 25 is disengaged from the inside of the chuck 26 and the third clamping block 24, and then the grinding disc 6 is rotated so that the third clamping block 24 moves inside the third clamping groove 27. When the third clamping block 24 moves to the specified position inside the third clamping groove 27, the grinding disc 6 is pulled, and the chuck 26 is moved, so that the grinding disc 6 can be disassembled.

[0040] When the staff uses this device to grind the workpiece and needs to adjust the grinding depth, they first make the grinding disk 6 work normally, and then the staff rotates the rotating rod 71. When the rotating rod 71 rotates, the connecting tube 9 can be driven to rotate through the first clamping block 12, and then the connecting tube 9 can drive the first gear 75 to rotate when it rotates. When the first gear 75 rotates, the rotating tube 73 can be rotated through the second gear 8, and then the moving rod 74 can drive the power mechanism 3 to move. When the power mechanism 3 moves, it can drive the grinding disk 6 to move, so that the grinding depth can be adjusted by controlling the number of rotations of the rotating rod 71, which makes it convenient for the staff to process the workpiece at different grinding depths, thereby improving the workpiece processing efficiency to a certain extent.
