[0012] Furthermore, the main body is provided with seven metal pins, which are distributed on the main body at appropriate sizes.
[0013] With the above technical solution, metal needles are evenly installed at the bottom of the main body.
[0014] Furthermore, the depth of the circular grooves on the upper grinding stone is controlled to be 0.5-2mm each time.
[0015] Using the above technical solution, the depth of the circular grooves on the upper grinding stone can be controlled according to the usage requirements each time.
[0016] Furthermore, circular grooves are scraped into the grinding stone, with the distance between every two grooves being relatively evenly distributed and ≤40mm.
[0017] Using the above technical solution, the spacing between the grooves in the upper grinding stone circle can be controlled according to the usage requirements. Beneficial effects
