Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0020] Depend on Figure 1 , Figure 2 and Figure 3It is given that the improved anti-slip locking nut of the utility model has an inner wall of the first nut 100 evenly provided with an action groove, and the inner wall of the action groove is slidably connected with a clamping block 101, which is convenient for clamping and fixing the bolt, and the clamping block 101 is made of rubber material, which is convenient for deformation and fitting with the outer wall of the bolt for limited clamping, and the inner cavity of the action groove is slidably connected with a pushing block 102, which is convenient for pushing the clamping block 101 to move for clamping, and the right side wall of the pushing block 102 is fixedly connected with a fixing ring 103, which is convenient for driving the pushing block 102 to move, and the right side wall of the fixing ring 103 is rotatably connected with a second nut 104, which is convenient for limiting and fastening the first nut 100 through the second nut 104, and the left side wall of the second nut 104 is provided with an annular groove, and the fixing ring 103 is located in the inner cavity of the annular groove.

[0021] In this embodiment, the first nut 100 and the second nut 104 are synchronously screwed and fixed on the bolt. After the first nut 100 is screwed to the specified position, the component is fixed, and then the second nut 104 is continued to be rotated to move it on the bolt, and the fixing ring 103 is pushed to move by the second nut 104, and the pushing block 102 is pushed to move by the fixing ring 103, and the clamping block 102 is pushed to move by the pushing block 102, so that the clamping block 102 clamps and fixes the bolt. At this time, the second nut 104 moves to the side wall of the first nut 100, and the first nut is limited and fixed by the second nut 104, which can make it easy for the device to tighten and prevent the first nut 100 from slipping, and prevent the first nut 100 from sliding and loosening due to vibration, which is beneficial to the connection and tightening of the device.

[0022] The outer wall of the first nut 100 is provided with a sliding groove, and the inner wall of the sliding groove is slidably connected with a tooth frame 105, which facilitates the second nut 104 to be clamped and limited by the tooth frame 105. The outer wall of the second nut 104 is evenly provided with grooves, and the tooth frame 105 matches the grooves.

[0023] By pushing the tooth frame 105 to move in the inner cavity of the sliding groove, the clamping frame 105 is moved to the inner cavity of the clamping groove, and the second nut 104 is limited by the clamping frame 105, so that the first nut 100 and the second nut 104 can rotate synchronously, which is convenient for the first nut 100 and the second nut 104 to be screwed onto the bolt, and the device can facilitate the connection between the first nut 100 and the second nut 104, so that the first nut 100 and the second nut 104 can rotate synchronously, which is beneficial to the screw connection operation.
