[0037] Specifically, by setting up the adjustment mechanism 5, the adjustment block 502 on the threaded rod 501 is moved to achieve contact with the push block 503, thereby pushing the connecting plate 504 to move, thereby pushing the movable block 505 to move to the side away from the center of the circle, thereby reducing the distance between the grinding rod 404 and the grinding block 403, thereby achieving the purpose of changing the grinding particle size.

[0038] like Figure 4 As shown, an armrest is connected to the front of the adjustment block 502 for rotating the adjustment block 502 .

[0039] Specifically, the armrest is provided to facilitate the rotation of the adjustment block 502 , thereby achieving the purpose of adjusting the movable block 505 .

[0040] like Figure 4 As shown, a movable rod 506 is connected to the front of the movable block 505, and a fixed plate 507 is also installed in the installation groove of the grinding turntable 402; one end of the movable rod 506 movably passes through the fixed plate 507; a spring 508 is provided on the outer wall of the movable rod 506 for pulling the movable block 505 to move.

[0041] Specifically, the spring 508 is provided to pull the movable block 505 to move on the fixed plate 507 through the movable rod 506, so as to achieve the purpose of returning to the center of the circle.

[0051] When the grinding particle size needs to be adjusted to be smaller, the handle is turned to rotate the adjusting block 502 so that its outer wall moves closer to the inside, which pushes the push block 503 to move, and then pushes the connecting plate 504 to move, thereby driving the movable block 505 to move, thereby pushing the distance between the grinding rod 404 and the grinding block 403, so as to achieve grinding of smaller particle size;

[0052] By rotating the handle in the opposite direction and under the action of the spring 508, the movable block 505 is pulled to move and reset, thereby expanding the distance between the grinding rod 404 and the grinding block 403, thereby grinding larger particles.

[0053] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
