The grinding wheel body 2 is sleeved on the sleeve column 7 through the provided mounting hole 22, and is positioned and fitted with the sleeve column 7 through the use of the positioning pin 6 through the provided positioning hole 4, and the provided limiting grooves 5 are used to cooperate with the use of the limiting block 14;
[0024] like Figure 3 and Figure 4As shown, a group of left-right symmetrical positioning pins 6 are fixedly installed on the front end wall of the grinding wheel rod body 1, and a sleeve column 7 is fixedly installed on the front end wall of the grinding wheel rod body 1 and located between the positioning pins 6. An inner cavity 8 is opened inside the sleeve column 7, and a group of upper and lower symmetrical through-holes 9 communicating with the inner cavity 8 are opened on the outer wall of the sleeve column 7. A threaded hole 10 communicating with the inner cavity 8 is also opened on the front end wall of the sleeve column 7. After the grinding wheel body 2 is sleeved on the sleeve column 7, the positioning pin 6 will be inserted into the positioning hole 4, and the inner cavity 8 opened in the sleeve column 7 is used to cooperate with the movable plate 11, and the limit block 14 can be inserted into the limit groove 5 through the through-hole 9 opened, and the threaded hole 10 opened is used to cooperate with the screw 19 to realize the thread rotation operation;
[0025] like Figure 5 and Figure 6 As shown, the screw rod 19 is threadedly connected to the threaded hole 10, and a rotating block 20 is fixedly installed at the rear end of the screw rod 19, and a knob 21 is fixedly installed at the front end of the screw rod 19. Turning the knob 21 will drive the screw rod 19 to realize the threaded rotation and backward movement operation in the threaded hole 10, and drive the rotating block 20 to rotate in the convex groove 13. At the same time, the movable plate 11 is pushed to move by the rotating block 20;
