When the insertion rod 307 is separated from the insertion hole, the spring 309 is in a compressed state. Through the provided positioning structure 300, the cutter 301 can be quickly limited and fixed. When it is necessary to quickly limit and fix the cutter 301, by completely inserting one end of the cutter 301 into the slot 303, then while pulling the insertion rod 307, rotating the rotating handle 306 to drive the threaded rod 305 to be threadedly inserted into the threaded hole 304 to fix the mounting block 110 and the cutter 301, and then releasing the insertion rod 307, the insertion rod 307 is inserted into the corresponding insertion hole under the elastic action of the spring 309 to lock the threaded rod 305, so as to quickly limit and fix the cutter 301.

[0033] The grinding assembly 200 includes a driving motor 201 fixedly installed on the top of the support table 5. A machine box is arranged outside the driving motor 201. A material receiving frame 202 is fixedly installed on one side of the upper end surface of the machine tool body 1. The output end of the driving motor 201 penetrates through the bearing to the inside of the material receiving frame 202 and is fixedly installed with a grinding cutter 203. Through the provided grinding assembly 200, the cutter 301 can be effectively ground. When it is necessary to grind the cutter 301, by starting the driving motor 201 to drive the grinding cutter 203 to rotate, the grinding cutter 203 grinds the cutter 301, and at the same time, the ground debris falls into the material receiving frame 202 for collection, so as to effectively grind the cutter 301.

[0035] Meanwhile, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0036] During operation, first, one end of the tool 301 to be polished is completely inserted into the slot 303. Then, while pulling the insertion rod 307, the rotating handle 306 is rotated to drive the threaded rod 305 to be threaded into the threaded hole 304 to fix the mounting block 110 and the tool 301. Then, the insertion rod 307 is released. Through the elastic action of the spring 309, the insertion rod 307 is inserted into the corresponding jack to lock the threaded rod 305, so as to quickly limit and fix the tool 301. Then, the electric push rod 3 is started to drive the moving box 4 to move below the grinding tool 203 in the grinding assembly 200. Then, the first driving motor 101 is started to drive the first rotating rod 102 to rotate. Through the mutual cooperation between the bumps 6 on both symmetric sides of the first rotating rod 102 and the grooves symmetrically provided on the inner wall of the sleeve rod 103, the sleeve rod 103 is driven to rotate. The sleeve rod 103 drives the driving bevel gear 106 to rotate. The driving bevel gear 106 drives the driven bevel gear 108 to rotate. The driven bevel gear 108 drives the mounting block 110 at one end of the connecting rod 109 to rotate, so as to rotate the tool 301. By starting the second driving motor 112 to drive the cam 114 on the second rotating rod 113 to rotate, while the cam 114 rotates, the transmission rod 115 is driven to perform a circumferential rotation. The transmission rod 115 drives the Y-shaped bracket 116 to rotate up and down. While the Y-shaped bracket 116 rotates up and down, through the mutual cooperation between the arc-shaped block 403, the ball 404 and the I-shaped limit block 405, the tool 301 can be driven to move up and down, so as to perform multi-directional adjustment on the tool 301 in the positioning structure 300. At the same time, the driving motor 201 is started to drive the grinding tool 203 to rotate, and the grinding tool 203 grinds the tool 301. Meanwhile, the ground debris falls into the material receiving frame 202 for collection.
