The lifting column 205 is located on the inner side of the side tube 200, and a mounting ring 206 is fixedly provided on the bottom inner side of the side tube 200. The bottom of the limiting rod 202 passes through the inside of the mounting ring 206. Multiple groups of jacks 203 are evenly opened along the circumferential direction of the lower ring 201. The lower ring 201 is located on the top outer side of the tool rod 101, and the lower ring 201 is fixed on the tool rod 101. The side tube 200 is fixed on the outer side of the E-type nut 102. Through the designed limiting mechanism, the E-type nut 102 can be limited during use, reducing the probability of the E-type nut 102 being loosened due to vibration during use, resulting in the loosening of the fixed chamfering cutter head 103, thereby improving the processing effect and quality of the chamfering tool on the workpiece.

[0025] In this embodiment, preferably, a protective component is provided on the outside of the chamfering cutter head 103, and the protective component includes a protective tube 300. A sponge layer 301 is fixedly provided on the inner wall of the protective tube 300.

[0027] The working principle and use process of this utility model:

[0028] When the utility model is in use, the E-type nut 102 is first sleeved on the outer bottom of the chamfering cutter head 103, and then the bottom of the chamfering cutter head 103 is passed through the E-type jacket and inserted into the inside of the cutter rod 101, and then the E-type nut 102 is rotated downward to be screwed together with the outer top of the cutter rod 101 through a thread. During this process, the bottom of the limiting rod 202 on the E-type nut 102 is inserted into the inside of the corresponding insertion hole 203, and the limiting rod 202 can be squeezed downward under the expansion and contraction action of the fixing spring 204. During use, the limiting rod 202 inserted into the insertion hole 203 can limit the E-type nut 102 to reduce the probability of loosening. When it needs to be disassembled, it can be operated according to the opposite principle mentioned above;

[0029] When moving the chamfering tool, the sponge layer 301 on the protective tube 300 is put on the top outer side of the chamfering head 103. At this time, the top of the chamfering head 103 is inserted into the groove in the sponge layer 301, which can protect the top outer side of the chamfering head 103. When the chamfering tool needs to be used, it can be operated according to the above-mentioned principle.
