In order to affect the processing quality, a frosted pad 56 is fixedly connected to the outer wall of the arc-shaped tooth 55 away from the annular groove 54. The frosted pad 56 is provided to increase the friction between the arc-shaped tooth 55 and the oil distribution plate, thereby reducing slippage during clamping.

[0026] Reference Figure 3-Figure 4 The adjusting mechanism 6 includes a slide groove 61, which is provided on one side outer wall of the fixture 53. The inner walls on both sides of the slide groove 61 are slidably connected with mounting brackets 62. The bottom outer wall of the mounting bracket 62 is fixedly connected with a limiting rod 63.
