[0018] The anti-loosening assembly includes a pushing rod 4, a mounting groove 5, a first slide groove 6 and a second slide groove 7. The first slide groove 6 is obliquely opened on the side wall of the nut 3 and the first slide groove 6 passes through the nut 3. The mounting groove 5 is opened on the side wall of the screw rod 2 and the opening size of the mounting groove 5 is consistent with the opening size of the first slide groove 6. The mounting groove 5 is coaxial with the first slide groove 6. The bottom end of the pushing rod 4 is tilted downward and inserted into the first slide groove 6 and finally falls into the mounting groove 5. The second slide groove 7 is opened at the bottom of the first slide groove 6 and the axis of the second slide groove 7 is parallel to the first slide groove 6. The bottom end of the pushing rod 4 is fixedly provided with a first fixing block 8, and the bottom end of the second slide groove 7 is fixedly provided with a second fixing block 9. The first fixing block 8 is extended in the second slide groove 7. A telescopic rod 10 is provided between the first fixed block 8 and the second fixed block 9, and the rod body of the telescopic rod 10 is sleeved with a spring 11.

[0019] Furthermore, a feed groove 12 is provided above the rod body of the push rod 4, and a feed hole 13 is provided at the bottom of the feed groove 12 on one side close to the mounting groove 5. The feed hole 13 is vertically penetrated and provided on the push rod 4. When the push rod 4 is pulled out, the feed hole 13 can be located in the gap between the nut 3 and the screw rod 2.

[0020] Furthermore, a first washer 14 is provided between the nut 3 and the bolt head 1, and the first washer 14 is movably sleeved on the outside of the screw 2. The first washer 14 can act as a buffer to prevent the nut 3 from being damaged due to excessive tightening.

[0022] In the embodiment of this utility model, please refer to Figure 1-Figure 3When in use, the device can assist the nut 3 in tightening better through the anti-loosening component in the nut 3. First, the screw rod 2 is passed through the object to be tightened, and then the nut 3 is installed. The nut 3 is rotated and set below the object to be tightened. The worker first pulls out the push rod 4 slidingly set in the first slide 6. By rotating the nut 3, the object is tightly pressed between the nut 3 and the bolt head 1. A first washer 14 is set between the bolt head 1 and the nut 3 to protect the object and prevent it from being crushed. When the object is fixed, the worker can pour the anti-loosening glue into the feed trough 12 opened above the push rod 4. The bottom end of the feed trough 12 has a feed hole 13. When the worker pulls out the push rod 4, the feed hole 13 is located in the thread gap between the nut 3 and the screw rod 2. At this time, the anti-loosening glue will slowly fill between the nut 3 and the screw rod 2. The second washer 16 at the bottom of the nut 3 is engaged with the through groove 15 at the bottom of the nut 3, which can effectively prevent the anti-loosening glue from overflowing from the bottom. Since the object has been tightly pressed between the nut 3 and the bolt head 1, the anti-loosening glue can form a layer of anti-loosening glue film after the nut 3 is tightened, effectively preventing the nut 3 from loosening due to vibration, and the initial tightening work is now completed. After the anti-loosening glue has been filled, the worker releases the push rod 4. Since the bottom of the push rod 4 is provided with a first fixing block 8, the second fixing block 9 is provided in the second chute 7, and a telescopic rod 10 is provided between the first fixing block 8 and the second fixing block 9. The telescopic rod 10 is sleeved with a spring 11. When the worker releases the push rod 4, the first fixing block 8 will pull the push rod 4 along the direction of the first chute 6 and move diagonally downward. At this time, the end of the push rod 4 will be engaged in the installation groove 5 on the side wall of the screw rod 2, and the entire tightening work is now completed. The inclined push rod 4 will automatically insert the push rod 4 into the installation groove 5 due to the tension of the spring, which can not only provide tightening strength to the nut 3 on the side, but also add anti-loosening glue, effectively preventing the nut 3 from loosening due to vibration. It can effectively reduce the problem of loosening of automotive fasteners due to vibration.
