In the embodiment of the application, after the third buckle in the first connecting piece of fixed knot structure, the fourth buckle in the second connecting piece and the fifth buckle in the third connecting piece cooperate, can carry out the compactness with first connecting piece, second connecting piece and third connecting piece and block, reduced buckle quantity, solved simultaneously under the limited circumstances of fixed knot structure inner space, increase the problem of the design degree of difficulty.

Optionally, a first limiting member is further disposed on the first connecting member near the third buckle, and the first limiting member is located on one side of the third buckle near the third connecting member;

and a second limiting part is further arranged at a position, close to the fourth buckle, on the second connecting piece, and the second limiting part is positioned at one side, close to the third connecting piece, of the fourth buckle.

In this embodiment of the application, the first limiting part and the second limiting part are used to limit the fifth buckle 301 toward one side of the third connecting part, and at this time, the appearance surface of the third connecting part is pushed against the outer side of the housing, so as to fix the third connecting part along the axial direction, and the third connecting part cannot be separated from the housing.

While preferred embodiments of the present application have been described, additional variations and modifications of these embodiments may occur to those skilled in the art once they learn of the basic inventive concepts. Therefore, it is intended that the appended claims be interpreted as including the preferred embodiment and all such alterations and modifications as fall within the true scope of the embodiments of the application.

Finally, it should also be noted that, in this document, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or terminal that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or terminal. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other like elements in a process, method, article, or terminal that comprises the element.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
