Specifically, the driving rod 23 includes a limit cap 231 mounted on one end of the fixing sleeve 21 and a screw 232 disposed on the limit cap 231 and disposed in the fixing sleeve 21; the screw 232 is in threaded connection with the lifting sleeve 22. Thus, the limit cap 231 is erected at one end of the fixing sleeve 21 and cannot penetrate through the fixing sleeve 21, the screw 232 connected to the limit cap 231 is limited by the limit cap 231 when rotating and can only rotate without moving along the axis of the fixing sleeve 21, the lifting sleeve 22 is in threaded connection with the screw 232, the lifting sleeve 22 can only move along the fixing sleeve 21 through the matching of the limit stop 221 and the limit groove 211, and therefore when the driving rod 23 is rotated, the lifting of the lifting sleeve 22 can be effectively achieved through the screw 232, and the driving mode is simple, fast and simple in structure.

Specifically, the elevation sleeve 22 is provided with a scale corresponding to the limit stopper 221. In this way, in the process of lifting the lifting sleeve 22, the lifting range of the lifting sleeve 22 can be determined by observing the relative position of the limit stop 221 and the scale provided on the lifting sleeve 22, which can help to more accurately adjust the angle of the grinding plate 200.

In particular, the support arm 1 is detachably connected to the grinder arm 100 by means of a clamp 11. More specifically, the clamp 11 comprises a hollow frame 111 which is sleeved on both the grinder arm 100 and the support arm 1, and a fastener 112 which is screwed with the hollow frame 111; the fastening member 112 passes through the hollow frame 111 and abuts against the support arm 1. Therefore, the angle adjustment tool of the whole grinding plate 200 of the grinding machine and the arm 100 of the grinding machine can be effectively and conveniently disassembled and assembled, when the support arm 1 and the arm 100 of the grinding machine are required to be fixed, the support arm 1 and the arm 100 of the grinding machine are only required to be arranged in the hollow frame 111, and then the fastener 112 penetrates through the hollow frame 111 and is screwed and abutted to the support arm 1 to realize the fixation. More specifically, the hollow frame 111 includes a first frame 1111 and a second frame 1112, the first frame 1111 is further provided with a groove on a side facing the second frame 1112, and the second frame 1112 is provided with a protrusion matching with the groove facing the first frame 1111, thereby facilitating assembly of the first frame 1111 and the second frame 1112.

Specifically, referring to fig. 2 and 3, the supporting arm 1 is provided with a threaded hole 10 corresponding to the fixing sleeve 21, so that the fixing sleeve 21 can be fixed on the supporting arm 1 by threaded connection, and the lifting sleeve 22 is disposed through the threaded hole 10, that is, the lifting sleeve 22 can pass through the threaded hole 10 and extend into the fixing sleeve 21.

Specifically, the pressing assembly 3 comprises a pressing seat 31 arranged on the lifting sleeve 22 and an abutting piece 32 rotatably connected to the pressing seat 31; the contact point of the abutment 32 with the abrasive plate 200 is disposed offset from the axis of rotation of the abutment 32. Thus, when the lifting sleeve 22 is lifted, the lifting sleeve 22 can drive the pressing base 31 and further drive the abutting piece 32 to push the grinding plate 200 to perform the angle adjustment of the grinding plate 200, and since the abutting piece 32 is rotatably connected with the pressing base 31 and the rotation axis of the abutting piece 32 deviates from the rotation axis of the abutting piece, the abutting piece 32 and the grinding plate 200 can have a plurality of abutting positions by rotating the abutting piece 32, so that the angle of the grinding plate 200 can be adjusted at a plurality of positions.

More specifically, the pressing base 31 is arc-shaped and the abutting pieces 32 are universal wheels, and the number of the abutting pieces 32 is two and is respectively arranged at two ends of the pressing base 31.
