Both transmission gears 310 are meshed and transmission-connected with the end gear 311, which improves the flexibility of the overall device and can drive the state of two fastening bolts 21 at the same time, further ensuring the stability of the tool body 1. The side of the friction ring 35 is provided with friction grooves for enhancing the friction between the tool body 1, and the columnar head 31 is provided with a hexagonal socket that can be matched with a hexagonal wrench. The shape of the slide plate 32 is consistent with the shape of the hexagonal socket. A sliding groove for passing the connecting rod 313 is provided on the first transmission shaft 36, and both ends of the connecting rod 313 are fixedly connected to the friction ring 35.

[0027] Working principle: first, put the tool body 1 on the output shaft of the cutting power equipment, then insert the hexagonal wrench into the hexagonal hole of the columnar head 31, and squeeze the slide plate 32. Because the slide plate 32 and the connecting rod 313 are fixedly connected through the slide rod 33, and the friction ring 35 is fixed on the connecting rod 313, the friction ring 35 will slide inside the first transmission shaft 36 after sliding with the slide plate 32, so that a gap is generated between the friction ring 35 and the tool body 1. Then, the columnar head 31 is driven to rotate by the wrench, and the first bevel gear 37 fixedly connected to the columnar head 31 through the first transmission shaft 36 is synchronously rotated on the tool body. 1 rotates internally, the first bevel gear 37 meshes with the second bevel gear 38, the second bevel gear 38 is fixed on the second transmission shaft 39, and the second transmission shaft 39 is fixedly connected to the transmission gear 310 and the disc shaft 23 respectively, so that the transmission gear 310 and the disc shaft 23 rotate synchronously, wherein the disc shaft 23 drives the square rod 22 fixedly connected thereto to rotate, and the fastening bolt 21 slidably connected to the square rod 22 is also threadedly connected to the auxiliary nut 25 fixed inside the tool body 1. Therefore, after the disc shaft 23 rotates, the fastening bolt 21 will be screwed out of the tool body 1 and then screwed into the cutting power device The two transmission gears 310 are meshed with the end gear 311 which is rotatably connected to the tool body 1 through the auxiliary bearing 312. When one transmission gear 310 rotates, the other transmission gear 310 rotates synchronously under the transmission of the end gear 311, and the other transmission gear 310 is also fixedly connected to the other disc-shaped shaft 23 through another second transmission shaft 39, so that the other fastening bolt 21 is synchronously screwed out of the tool body 1 and then synchronously screwed into the output shaft of the cutting power device, and then the tool body 1 is fixedly mounted on the cutting device through the threads on the two fastening bolts 21. The hexagonal wrench is then pulled out, and under the action of the return spring 34 fixedly connected to the slide plate 32 and the cylindrical head 31 at both ends, the slide plate 32, the slide rod 33, the connecting rod 313 and the friction ring 35 slide back, eliminating the gap between the friction ring 35 and the tool body 1, so that the friction pattern on the friction ring 35 contacts and cooperates with the tool body 1. At this time, a friction force that limits the rotation of the friction ring 35 can be formed, thereby limiting the rotation of the first transmission shaft 36, the first bevel gear 37, the second bevel gear 38 and even the second transmission shaft 39, and further locking the state of the fastening bolt 21.
