[0009] Preferably, the slider is in a T-shaped structure, and the slider is slidably connected to the mounting frame.

[0010] Preferably, one side of the movable block is inclined, and the movable block forms a detachable structure through screws and nuts.

[0011] Preferably, the reserved opening is integrated with the screw through slotting, and the inner side of the screw is a hollow structure.

[0012] In summary, due to the adoption of the above technical scheme, the present application has the following beneficial effects:

[0013] 1、In the present application, when people connect the bolt, the inclined side of the movable block first contacts the nut, and then the movable block is pushed into the installation frame in the screw, and the nut continues to connect with the screw, and then the movable block is removed by the cooperation of the nut, the connecting rod and the spring, and is supported on one side of the nut, so that the connection between the nut and the screw is strong and will not fall off.

[0020] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0021] REFERENCE Figures 1-4The top of the screw rod 1 is provided with a flange screw head 2, and movable blocks 3 are installed on both sides of the outer wall of the screw rod 1. The movable block 3 is connected to a connecting plate 10 on one side of the screw rod 1, and a connecting rod 4 is fixed on one side of the movable block 3 inside the screw rod 1. The inner side of the connecting rod 4 is a hollow structure, and the connecting rod 4 and the connecting plate 10 are through-set. By setting the inner side of the connecting rod 4 as a hollow structure, it is convenient for people to insert the screw into the movable block 3, pass through the connecting rod 4, and then connect it with the nut 5, which is conducive to the installation of the movable block 3. The other end of the connecting rod 4 is abutted with a nut 5, and the other end of the nut 5 is connected to a spring 7. The top of the nut 5 is fixed with a slider 6, and the screw 1 A mounting frame 8 is installed on the inside, and one side of the inner wall of the mounting frame 8 is connected to the other end of the spring 7. One side of the movable block 3 is inclined, and the movable block 3 constitutes a detachable structure by a screw and a nut 5. When the bolt and the nut are connected, the inclined side of the movable block 3 first contacts the nut, and the movable block 3 is squeezed and moved into the mounting frame 8. After the abutment is released, it can be moved out of the mounting frame 8 and supported on one side of the nut, which is convenient for preventing the bolt from loosening when being connected. The slider 6 is T-shaped, and the slider 6 and the mounting frame 8 are slidably connected. The slider 6 moves along the inner top of the mounting frame 8, so that when the spring 7 is reset, the nut 5 and the slider 6 can be pushed to move in the horizontal direction.

[0022] A reserved opening 9 is provided on the outer wall of the screw 1, and the reserved opening 9 forms an integrated structure with the screw 1 through slotting, and the inner side of the screw 1 is a hollow structure. The setting of the reserved opening 9 is mainly to facilitate people to place the combination composed of the movable block 3, the connecting plate 10 and the connecting rod 4, and to facilitate people to complete the installation of the movable block 3 through the threaded connection work of the screw and the nut 5.

[0023] Working principle: When in use, the staff first connects the hexagonal flange bolt and the nut. As the nut moves along the threaded area to the movable block 3, the inclined side of the movable block 3 first contacts the nut. After the movable block 3 is squeezed, it moves into the installation frame 8. After the abutment is released, it can be moved out of the installation frame 8 and supported on one side of the nut, which is convenient for connecting the bolt and prevents it from loosening. When the movable block 3 is severely worn, people can replace it by removing the screws at the movable block 3.

[0024] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
