The positioning installation collar 301 is inserted into the inner ring surface of the connecting pin body 1. The fixing block 302 is fixedly connected to the inner ring surface of the connecting pin body 1. A nut 303 is fixedly connected to the side surface of the fixing block 302. An extension threaded rod 304 is inserted into the inner ring surface of the 3-ring. A wear-resistant rubber gasket 306 is fitted onto the outer ring surface of the extension threaded rod 304. A limit push plate 307 is fitted onto the outer ring surface of the extension threaded rod 304. A cover plate 309 is fitted onto the outer ring surface of the limit push plate 307. A connecting plate 310 is fixedly connected to the side surface of the cover plate 309. A connecting ring 311 is inserted into the inner ring surface of the connecting plate 310. A limit opening 30 is provided on the inner ring surface of the positioning and mounting collar 301. 5. The inner ring surface of the cover plate 309 has a snap-fit ​​opening 308. In use, the connecting ring 311 needs to be unfolded, and then the connecting plate 310 needs to be pulled. This allows the cover plate 309 to be removed from the limiting push plate 307. Next, the extension threaded rod 304 needs to be turned. Through the limiting action of the fixed block 302 and the nut 303, the limiting push plate 307 can be pushed, thus unfolding the connecting pin body 1. The anti-slip pad 5 on the outer ring surface of the connecting pin body 1... The connecting pin body 1 can be positioned and engaged using an anti-slip positioning mechanism, thus effectively preventing the connecting pin from coming loose. When the connecting pin is inserted, the positioning support plate 402 will first contact the inner surface of the item to be installed. After the connecting pin is further inserted, the positioning support plate 402 and the limiting rod 403 will move and adjust on the positioning connector 401. With the support of the spring 404, the positioning support plate 402 can be used to position and engage the connecting pin during installation.

[0026] Furthermore, the positioning and clamping mechanism 4 includes a positioning connector 401, a positioning support plate 402, a limiting rod 403, a spring 404, and a plug-in opening 405. The spring 404 is fixedly connected to the outer ring surface of the positioning connector 401, and the limiting rod 403 is fixedly connected to the side surface of the spring 404. The positioning connector 401 is installed on the side surface of the limiting rod 403, and the plug-in opening 405 is opened on the inner ring surface of the positioning connector 401. The positioning connector 401 facilitates the use and limiting of the limiting rod 403.

[0027] Furthermore, an anti-slip pad 5 is installed on the outer ring surface of the connecting pin body 1, and the anti-slip pad 5 is arranged around the connecting pin body 1 with the connecting pin body 1 as the center point. The anti-slip pad 5 arranged around the connecting pin body 1 with the connecting pin body 1 as the center point can facilitate the anti-slip connection of the connecting pin body 1.

[0028] Furthermore, a connecting plate 310 is sleeved on the outer ring surface of the limiting push plate 307, and the size of the snap-fit ​​opening 308 and the cover plate 309 are matched.

[0029] Furthermore, the positioning support plate 402 is connected to the positioning plug 401 via the limiting rod 403, and the plug opening 405 and the limiting rod 403 are matched in size. The plug opening 405, which is matched in size with the limiting rod 403, can facilitate the use and limiting of the limiting rod 403.

[0030] Furthermore, the spring 404 connects the limiting rod 403 and the positioning connector 401, and there are multiple springs 404. The multiple springs 404 facilitate the connection between the springs 404 and the positioning connector 401.

[0031] Furthermore, the nut 303 is connected to the connecting pin body 1 via the fixing block 302, and the fixing block 302 is arranged around the nut 303 as the center point. The fixing block 302 arranged around the nut 303 as the center point can facilitate the stable connection of the nut 303 to the connecting pin body 1.

[0032] Working principle: When the connecting pin needs to be used, the connecting pin with anti-loosening structure needs to be inserted into the desired position like a traditional connecting pin. Then, the connecting ring 311 needs to be unfolded, and then the connecting plate 310 needs to be pulled. This allows the cover plate 309 to be removed from the limiting push plate 307. Next, the extension threaded rod 304 needs to be turned. Through the limiting of the fixed block 302 and the nut 303, the limiting push plate 307 can be pushed, thus unfolding the connecting pin body 1. The anti-slip pads 5 on the outer ring surface can be used to anti-slip position and engage the connecting pin body 1, thereby effectively preventing the connecting pin from falling off. When the connecting pin is inserted, the positioning support plate 402 will first contact the inner ring surface of the item to be installed. After the connecting pin is continued to be inserted, the positioning support plate 402 and the limiting rod 403 will move and adjust on the positioning connector 401. With the support of the spring 404, the positioning support plate 402 can be used to position and engage the connecting pin during installation.
