Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0041] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components.

[0043] The elastic positioning member of the embodiment of the utility model is described in detail below with reference to the accompanying drawings.

[0044] Reference Figures 1 to 3 As shown, the elastic positioning member provided according to the embodiment of the utility model includes a housing 10, a positioning member 20 and an elastic member 30;

[0045] The shell 10 is made of stainless steel, so the shell 10 is not easy to rust, has high hardness, is not easy to be damaged, and is convenient to use.

[0046] The positioning member 20 is movably disposed in the housing 10, and the elastic member 30 is disposed in the through hole 11 and connected to the positioning member 20, and is used to push the positioning member 20 out of the housing 10 when the positioning member 20 is not acted upon by an external force. Preferably, the elastic member 30 is a telescopic spring.

[0047] The positioning member 20 is used to support and position the parts. It is connected to the elastic member 30. Therefore, when the positioning member 20 is compressed, it can properly avoid the parts and compress the elastic member 30. In this way, the wear between the positioning member 20 and the parts can be reduced to a certain extent. When the positioning member 20 is not compressed, it can be lifted up and reset by the elastic member 30, and then it can be reused. The elastic member 30 adopts a telescopic spring, so it has good elasticity.

[0048] Specifically, when the present application is in use, the parts are matched with the positioning piece 20, and the parts will exert a certain pressure on the positioning piece 20. After the positioning piece 20 is pressed, it will appropriately avoid the parts. In this way, the friction between the parts will be reduced, thereby reducing the wear between the two. To a certain extent, the service life of the present application can be improved.

[0049] According to the elastic positioning member provided in the embodiment of the utility model, when positioning the parts, the wear between the parts and the elastic positioning member can be reduced, and to a certain extent, the service life of the application can be improved.

[0050] Advantageously, in one embodiment of the utility model, a through hole 11 is provided inside the housing 10, an upper annular stopper 111 is provided at the upper end of the inner wall of the through hole 11, and a lower annular stopper 112 is provided at the lower end of the inner wall of the through hole 11;

[0051] The positioning member 20 is disposed in the through hole 11 and is limited in the through hole 11 by the upper annular limiting member 111 ; the elastic member 30 is disposed in the through hole 11 and is limited in the through hole 11 by the lower annular limiting member 112 .

[0052] That is to say, the positioning member 20 and the spring member are both arranged in the through hole 11, and are located between the upper annular limit member 111 and the lower annular limit member 112, so that the upper annular limit member 111 can block the positioning member 20 from above the positioning member 20, and the lower annular limit member 112 can block the elastic member 30 from below the elastic member 30, so that the positioning member 20 and the elastic member 30 can be assembled together inside the shell 10.

[0053] Advantageously, in an embodiment of the present invention, the housing 10 , the upper annular stopper 111 and the lower annular stopper 112 are integrally formed.

[0054] In this way, the production and processing of the upper annular limiting member 111 and the lower annular limiting member 112 can be facilitated, which is beneficial to improving production efficiency.

[0055] Advantageously, in another embodiment of the present utility model, the positioning member 20 includes a seat body 21 and a supporting ball head 22;

[0056] The seat body 21 is disposed in the through hole 11; the supporting ball head 22 is a hemispherical structure and is disposed on the upper surface of the base;

[0057] When the supporting ball head 22 is not acted upon by an external force, the elastic member 30 forces the seat body 21 to abut against the lower surface of the upper annular limiting member 111 , and the supporting ball head 22 passes through the through hole 1111 on the upper annular limiting member 111 .

[0058] The seat body 21 can be made of stainless steel material, and its outer diameter is smaller than the aperture of the through hole 11 in the shell 10, but larger than the aperture of the through hole 1111 on the upper annular limit member 111. In this way, the seat body 21 can move inside the through hole 11 and can be limited by the upper annular limit member 111. In other words, when the supporting ball head 22 is not pressed by parts, that is, when it is not subject to external forces, the elastic member 30 can push the supporting ball head 22 out of the through hole 1111, and the seat body 21 can be against the lower surface of the upper annular limit member 111, and then be limited in the through hole 11 by the upper annular limit member 111 without completely separating from the shell 10.

[0059] Advantageously, in some embodiments of the present invention, the support ball head 22 is made of POM material.

[0060] POM material is a type of synthetic resin material, also called polyoxymethylene resin. It is a white or black plastic particle. Its regular molecular structure and crystallinity make its physical and mechanical properties very excellent. It is often used to replace metal plastics. It has the characteristics of high hardness, light weight, high rigidity and high wear resistance. Therefore, the support ball head 22 is made of POM material, which can further reduce the wear between it and the parts, which is beneficial to the protection of this application and the parts.

[0061] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
