As shown in Fig. 1-13, this embodiment proposes a buckle for assembling the part 3 to be installed, the part 3 to be installed has a fixing hole 33, the buckle includes: a female buckle body 1 and a child buckle body 2, wherein:

The female buckle body 1 has a through hole 11 arranged axially along itself and a plurality of cantilevers 12 arranged around the through hole 11. The cantilever 12 is provided with a clamping part 121 on the side facing the through hole 11, and the clamping part 121 connects the through hole 11 It is divided into a first space 111 and a second space 112 .

The sub-buckle body 2 includes a rod body 21 slidably arranged in the through hole 11, the outer peripheral side of the rod body 21 is provided with a first protrusion 211, and the sub-buckle body 2 includes an initial state in which the first protrusion 211 is located in the first space 111, the first protrusion 211 is located in the second space 112 in the locked state and the first protrusion 211 is located in the dismounted state of the through hole 11 .

Wherein, when the sub-buckle body 2 is in the locked state, the first protrusion 211 supports the inner side of the cantilever 12, so that the extension width of the cantilever 12 is greater than the inner diameter of the fixing hole 33 of the component 3 to be installed; state and dismounted state, the extension width of the cantilever 12 is smaller than the inner diameter of the fixing hole 33 of the component 3 to be installed.

In this application, the rod body 21 of the sub-buckle body 2 slides from the first space 111 into the second space 112, and the inner side of the cantilever 12 is supported by the first protrusion 211 on the outer peripheral side of the rod body 21 and the cantilever 12 is deformed outward. , the extension width of the cantilever 12 is greater than the inner diameter of the fixing hole 33, and then the component to be installed 3 is fixed.

Out of the through hole 11, the cantilever 12 returns to its original shape, and the extension width of the cantilever 12 is smaller than the inner diameter of the fixing hole 33, so that the buckle can be separated from the component 3 to be installed, which can effectively solve the situation that the self is damaged during disassembly, and increases the duplication of the buckle. the number of times used.

In the related technology, the sub-button and the female buckle of the buckle or the mother-of-the-box are locked and fixed by threading or clamping. The buckle is forcibly separated, and in the process of forced separation, it is easy to cause the deformation of the buckle's own structure or the extrusion deformation of the fixing hole 33 of the part 3 to be installed, which will affect the number of times the buckle can be reused or cause damage to the part 3 to be installed. However, in this application, when the buckle is disassembled, the sub-buckle body 2 continues to slide along the axial direction of the through hole 11, and slides in a direction away from the first space 111, and the cantilever 12 is opened during the sliding process. The angle gradually decreases until the cantilever 12 returns to its original shape, so that no hard extrusion occurs between the buckle and the component 3 to be installed, thereby protecting the structure of the buckle itself and the component 3 to be installed.
