On the basis of the above embodiments, the present invention proceeds with detailed descriptions of technical features and functions thereof, so as to help those skilled in the art fully understand the technical solution of the present invention and reproduce it.

As shown in fig. 1, 3 and 4, the main body 1 is formed by bending a plate, and the cross section of the main body may be circular, and a notch 5 is formed on one side of the main body 1 for easy processing and assembly. Jaws 2 which are integrally formed with the body and are formed by upwardly extending plate bodies are distributed on the top of the body 1. In order to realize that the claw 2 fixes the inner induction head better, the claw 2 is close to the central position of the body 1 gradually in the process of extending upwards, and thus the induction head can stretch the claw 2 outwards after penetrating through the body 1 so as to realize stable connection with the connecting piece.

An upper limiting plate 3 is formed by bending the top of the clamping jaw 2 outwards, and a sufficient gap is reserved between the inner surface of the upper limiting plate 3 and the outer surface of the clamping jaw 2. The free end of the upper limiting plate 3 is in contact with the corresponding surface of the mounting part 12 when in use, so that the clamping and stable connection between the connecting piece and the mounting part 12 can be completed by matching with the lower limiting plate 4 described in the following paragraphs. Bottom distribution at body 1 has downwardly extending's plate body, outwards buckles in downwardly extending's plate body and body 1 bottom hookup location department, forms the utility model discloses in lower limiting plate 4. The upper surface of the lower limiting plate 4 is attached to the surface of the corresponding mounting portion 12 in use.

As shown in FIG. 2, the induction head of the present invention is an injection molding, the top of the induction head is a wear part 6, and the bottom of the wear part 6 is a clamping part 7. The clamping part 7 is a step structure formed by removing redundant materials on the induction head. The lower part of the clamping part 7 is a conical part 8, the bottom of the conical part 8 is a body connecting part 9 with a cylindrical structure, the bottom of the body connecting part 9 is a wear head limiting part 10 formed by an annular boss, and the outer diameter of the wear head limiting part 10 is larger than that of the body connecting part 9. Grooves are symmetrically processed on two sides of the clamping portion 7, the conical portion 8, the body connecting portion 9 and the wear head limiting portion 10, the grooves on the two sides are communicated with the wear portion 6, and the single lead 11 is bent at the position of the wear portion 6 and then placed into the grooves on the two sides.

When the clamp spring self-locking connecting piece is used, the clamp spring self-locking connecting piece penetrates into a through hole of the mounting part 12 through one end of the clamp claw 2 and the upper limiting plate 3, the mounting part 12 can be a brake shoe, and the upper limiting plate 3 is extruded from the through hole of the mounting part 12 to enable the clamp claw 2 to generate elastic deformation.
