Specific embodiment
Below in conjunction with the accompanying drawings and embodiment is further described to this utility model：
Embodiment one：Referring to shown in Fig. 1～3, a kind of screw tap fixed mechanism, including body, the body includes connecting portion 1
And fixed part 2, the bottom surface of the connecting portion 1 is connected with the top of the fixed part 2, and the connecting portion 1 is integrated with fixed part 2
Structure, the section of the connecting portion 1 is in tetragon；The bottom of the fixed part 2 is provided with a location hole 3, and the location hole 3 is many
Side shape location hole；The bottom outer-edge of the fixed part 2 faces down and is extended with 4 pieces of arc extension boards 4, wherein, arc extension board 4
Top outer edge surface is flushed with the bottom outer-edge face of fixed part 2, and the bottom of arc extension board 4 is outward-dipping, that is, per described in block
