Detailed Description

In order to make the above objects, features and advantages of the present invention more clearly understood, the present invention will be further described with reference to the accompanying drawings and examples. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the present invention is not limited to the limitations of the specific embodiments of the present disclosure.

In a first embodiment, please refer to fig. 1, the present invention provides a technical solution: the utility model provides a firm wear-resisting novel numerical control cutter, including blade 1, one side sliding connection of blade 1 has tool bit 2, threaded hole 3 has all been seted up on blade 1 and tool bit 2's surface, it is connected with fixing bolt 4 to rotate between

screw hole

3, 3 equidistance arrangements in one side of tool bit 2 of screw hole, through setting up multiunit screw hole 3, the length that makes tool bit 2 can obtain adjusting, screw hole 3 meshes with fixing bolt 4 mutually, through setting up screw hole 3 with 4 intermeshing of fixing bolt, when fixing bolt 4 when 3 rotations of screw hole, fixing bolt 4 then can constantly remove in screw hole 3 this moment.

Referring to fig. 1-4, a spring 5 is mounted on one side of the cutter head 2 opposite to the threaded hole 3, a positioning ball 6 is fixedly connected to one end of the spring 5, positioning holes 7 are formed in the inner wall of the cutter body 1, the positioning holes 7 are equidistantly arranged on the inner wall of the cutter body 1, the positioning holes 7 are spherical, and the cutter head 2 with different lengths is positioned by arranging a plurality of groups of positioning holes 7.
