When it is necessary to grind up and down, the placement plate 43 is loosened to let the driving spring 44 drive the placement plate 43 to move its position. By setting the support frame 41, the slide rod 42, the placement plate 43 and the driving spring 44, the position of the motor 2 can be fixed to a certain extent, and the grinding of the cylinder body 1 is convenient.

[0023] The upper surface of the placement plate 43 is fixedly connected with a sleeve 46, and the sleeve 46 is sleeved on the surface of the motor 2. The side wall of the placement plate 43 is fixedly connected with a handle 45; when working, the handle 45 is pushed to allow the handle 45 to drive the placement plate 43 to move. By setting the sleeve 46, the position of the motor 2 in the placement plate 43 can be limited.

[0024] The surface of the sleeve 46 is rotatably connected to a rotating rack 47, and the surface of the rotating rack 47 is covered with a soft sleeve 48; when working, the rotating rack 47 is pushed to allow the rotating rack 47 to drive the soft sleeve 48 to rotate, and the soft sleeve 48 is squeezed on the surface of the motor 2. The rotating rack 47 and the soft sleeve 48 can reduce the possibility of the motor 2 falling out of the placement plate 43.
