[0024] The threaded rotating rod 35 is composed of a threaded shaft end and a knob end, and a buckle cover 34 is mounted on the outer side of the rotating shaft 31 through a groove.

[0025] Four column end structures are arranged inside the baffle plate 32 , and the column ends of the baffle plate 32 are inserted into the sides of the grinding wheel 33 through positioning holes.

[0026] The clamping component 36 includes two oppositely arranged clamping blocks 365 . The vertical section of the clamping block 365 is a trapezoidal structure. A clamping pin 366 is connected to the right side of the clamping block 365 , and the clamping pin 366 is inserted into the side of the grinding wheel 33 through a clamping slot.

[0027] The right side of the bottom end of the clamping block 365 is connected to a movable block 363, and the movable block 363 is embedded in the limiting plate 362 through a limiting groove. The bottom end of the movable block 363 is connected to a supporting spring 364, and the bottom end of the supporting spring 364 is connected and fixed to the inner wall of the limiting groove of the limiting plate 362.

[0028] Two limit plates 362 are provided, and the two limit plates 362 are connected and fixed via a guide shaft 361 . The guide shaft 361 is inserted into the interior of the rotating shaft 31 through a guide groove, and the guide shaft 361 is threadedly sleeved on the surface of the threaded rotating rod 35 .

[0029] Two guide rails 43 are symmetrically connected to the inner side of the bracket 42, and the guide rails 43 are embedded in the base 1 through guide grooves.

[0030] The threaded shaft end of the threaded rotating rod 35 can be inserted into the inside of the rotating shaft 31, and the knob end of the threaded rotating rod 35 is located outside the rotating shaft 31. By twisting the threaded rotating rod 35, the position of the clamping component 36 can be conveniently adjusted. When the threaded rotating rod 35 is rotated, the buckle cover 34 can be buckled on the outside of the rotating shaft 31, and then the threaded rotating rod 35 can be blocked to prevent the threaded rotating rod 35 from rotating and moving easily. When the grinding wheel 33 is sleeved on the surface of the rotating shaft 31, The right side of the grinding wheel 33 is fitted to the disc end of the baffle plate 32, and the column end of the baffle plate 32 is inserted into the positioning hole of the grinding wheel 33, and then the grinding wheel 33 can be guided and positioned to ensure the convenience of installation of the grinding wheel 33. When the grinding wheel 33 is installed on the surface of the rotating shaft 31, the guide shaft 361 moves on the surface of the threaded rotating rod 35, and the movement of the guide shaft 361 can drive the limit plate 362 to move, so that the limit plate 362 moves and pushes the clamping block 365 to move, and the clamping block 365 moves.

The guide groove on the side of the machine base 1 can guide the guide rail 43 to ensure the stability of the bracket 42 when it moves up and down, and to prevent the bracket 42 from deviating and shaking during movement.

[0031] Working principle: According to the attached Figure 2 With attached Figure 3 As shown, when the grinding wheel 33 is disassembled and assembled, the grinding wheel 33 can be sleeved on the surface of the rotating shaft 31.
