[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," "the other end," and the like, indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They are not intended to indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "provided with," "connected," etc. should be understood in a broad sense. For example, "connected" can mean 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 an indirect connection through an intermediate medium, or it can be internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0022] like Figures 1 to 4 As shown, this embodiment is an anti-drop-off plug pin, comprising a pin pin guide seat 1 and a pin pin body 2, wherein a placement groove 11 is provided inside the pin pin guide seat 1, and the pin pin body 2 is snapped into the placement groove 11, and a plug end 26 is fixedly installed on the top of the pin pin body 2, and the top of the plug end 26 passes through the outside of the pin pin guide seat 1, and two slide grooves 27 are provided on both sides of the top of the pin pin body 2, and sliders 28 are slidably connected in the four slide grooves 27, and a spring 22 is fixedly connected to one side of the two sliders 28, and the spring 22 is close to the top of the pin pin body 2. A spring 21 is fixedly connected to one side of the pin needle body 2, and one end of the spring 21 is fixedly connected to one side of the pin needle body 2. During the process of inserting the pin needle into the connector, the spring piece 22 is subjected to pressure and moves axially along the slide groove 27 through the slider 28. The elastic force of the spring 21 gives resistance to the two spring pieces 22, and the spring pieces 22 contact the inner wall of the connector, thereby effectively preventing the pin needle from falling off. At the same time, the spring piece 22 slides along the slide groove 27 through the slider 28 to facilitate the pin needle to be pulled out later, which is convenient to use and improves the practicality of the pin needle.

[0023] Furthermore, a rubber pad 23 for increasing the friction between the pin needle body 2 and the connector is provided on the side of the spring piece 22 away from the pin needle body 2. The rubber itself has good damping properties, which increases the friction between the pin needle body 2 and the inner wall of the connector, thereby improving the anti-falling effect of the pin needle body 2 of the utility model.

[0024] Furthermore, the spring piece 22 is arranged in an arc shape, and the arc-shaped spring piece 22 itself can withstand a large deformation and maintain stability, thereby increasing the service life of the spring piece 22.

[0025] Furthermore, the spring 21 is a conical coil spring 21. When the conical coil spring 21 is subjected to external load pressure, it provides a resistance force boundary and pushes back to resist the external pressure, thereby enhancing the resistance of the spring 22 to the inner wall of the connector, thereby improving the anti-falling effect of the pin needle body 2.

[0026] Furthermore, the pin needle guide seat 1 is provided with a limit platform 12 on both side walls of the placement groove 11, and a limit groove 24 is provided at the connection between the pin needle body 2 and the pin needle guide seat 1. The limit groove 24 and the limit platform 12 are snap-fitted together. The pin needle body 2 and the pin needle guide seat 1 are snap-fitted together through the limit groove 24 and the limit platform 12, thereby improving the stability and firmness of the snap-fit ​​between the pin needle body 2 and the pin needle guide seat 1.

[0027] Furthermore, a cover plate 13 is provided at the front end of the pin needle guide seat 1, and a through hole is opened in the cover plate 13. The cover plate 13 is also provided with a screw (not shown in the figure). A first screw hole 25 is opened inside the pin needle body 2. The screw passes through the through hole and is fixedly connected to the first screw hole 25, which facilitates the fixing or disassembly of the pin needle body 2.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
