[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] This invention allows for long-term stable use without loosening or falling off. Tightening the first tightening end allows the threaded post to be inserted into the workpiece. Tightening the auxiliary limiting nut locks and limits the fixed nut, ensuring its secure and stable operation. Tightening the second tightening end allows the auxiliary stabilizing threaded post to be inserted into the auxiliary threaded hole, causing the extrusion rollers to rotate and extrude at the bottom of the extrusion limiting disc. This provides sufficient extrusion support to the bottom of the extrusion limiting disc, ensuring that the auxiliary limiting nut and the fixed nut can be securely installed on the threaded post for a long time without loosening or falling off, resulting in stable fastening performance.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4The present invention provides an embodiment of a special alloy fastener with anti-loosening function, comprising a first screw-on end 1, a threaded post 2, a fixed nut 3, an auxiliary limiting nut 4, a compression limiting disc 5, and an auxiliary support 6. The first screw-on end 1 is fixedly connected to the top of the threaded post 2. The fixed nut 3 is threadedly rotatably mounted on the threaded post 2. The auxiliary limiting nut 4 is threadedly rotatably mounted on the threaded post 2 and is located at the bottom of the fixed nut 3. The compression limiting disc 5 is fixedly connected to the bottom of the auxiliary limiting nut 4. An auxiliary threaded hole 7 is provided in the middle of the bottom end of the threaded post 2. The auxiliary support 6 is provided at the bottom end of the threaded post 2.

[0018] The auxiliary support 6 includes a second screw end 8, a fixed support frame 9, a support tray 10, an extrusion wheel 11, and an auxiliary stabilizing threaded post 12. The support tray 10 is fixedly connected to the upper end of the second screw end 8, the auxiliary stabilizing threaded post 12 is fixedly connected to the middle of the upper end of the support tray 10, the fixed support frame 9 is evenly fixedly connected to the upper end of the support tray 10, and the extrusion wheel 11 is rotatably engaged inside the upper end of the fixed support frame 9.

[0019] The auxiliary stabilizing threaded post 12 is adapted to the auxiliary threaded hole 7. The auxiliary stabilizing threaded post 12 is threaded into the inside of the auxiliary threaded hole 7, and the auxiliary stabilizing threaded post 12 can rotate and move inside the auxiliary threaded hole 7 for adjustment.

[0020] The extrusion roller 11 is located at the bottom of the extrusion limiting plate 5 and can provide extrusion support.

[0021] A compression ring is provided at the bottom of the first screwing end 1 to assist in the compression contact between the limiting nut 4 and the fixing nut 3, thereby playing a role in stable support and limiting.

[0022] Working principle: By using a tool to screw the first screwing end 1, the threaded post 2 can be screwed into the interior of the workpiece. By screwing the auxiliary limiting nut 4, the fixed nut 3 can be locked and limited, making the fixed nut 3 firm and stable during use. By screwing the second screwing end 8, the auxiliary stabilizing threaded post 12 can be screwed into the interior of the auxiliary threaded hole 7, so that each extrusion roller 11 rotates and extrudes at the bottom of the extrusion limiting plate 5, which can fully extrude and support the bottom of the extrusion limiting plate 5. This allows the auxiliary limiting nut 4 and the fixed nut 3 to be firmly set on the threaded post 2 for a long time without loosening or falling off, and the fastening and locking performance is stable.
