An auxiliary structure 4 is arranged on the surface of the screw 1. By setting the auxiliary structure 4, the staff can rotate the screw 1 without tools, thus facilitating the staff to disassemble the bolt.

[0029] Next, specifically describe the specific settings and functions of its limiting structure 3 and auxiliary structure 4.

[0030] Referring to Figure 2 、 Figure 5 and Figure 6As shown in the figure, in this embodiment: The limiting structure 3 includes two mounting holes 311, both of the two mounting holes 311 are opened on the surface of the nut 2, the inner wall of the mounting hole 311 is threadedly connected with a tapered rod 309, and a connecting groove 310 is opened on the surface of the tapered rod 309. The inner walls of both of the two mounting holes 311 are slidably connected with elastic sleeves 308, a short rod 312 is fixedly installed on the inner wall of the elastic sleeve 308, and the elastic sleeve 308 can be stuck on the inner wall of the connecting groove 310 so that dust will not block the connecting groove 310. Both ends of the two short rods 312 away from each other are fixedly installed with connecting blocks 303, a round rod 302 is fixedly inserted into the interior of the connecting block 303, a fixing plate 301 is slidably sleeved on the arc surface of the round rod 302, and the surface of the fixing plate 301 is fixedly connected with the nut 2. A round block 307 is fixedly installed at one end of the round rod 302 away from the connecting block 303, and the connecting block 303 can assist the staff to move the short rod 312. Connecting cylinders 304 are slidably sleeved on the arc surfaces of both of the two round rods 302, push cylinders 306 are slidably sleeved on the arc surfaces of both of the two round rods 302, a spring 305 is sleeved on the arc surface of the round rod 302, and both ends of the spring 305 are fixedly connected with the connecting cylinder 304 and the push cylinder 306 respectively. The push cylinder 306 can move away from the fixing plate 301 under the elastic force of the spring 305. While the push cylinder 306 moves, it drives the push cylinder 306 to move. While the push cylinder 306 moves, it drives the round rod 302 to move. While the round rod 302 moves, it drives the connecting block 303 to move, achieving the effect of assisting in moving the connecting block 303.

[0031] Referring to Figure 3 and Figure 4 As shown in the figure, specifically, the auxiliary structure 4 includes a rectangular hole 44, the rectangular hole 44 is opened on the surface of the screw 1, a rotating plate 45 is slidably connected to the inner wall of the rectangular hole 44, a bearing hole 41 is opened on the surface of the screw 1, the bearing hole 41 is communicated with the rectangular hole 44, and a support rod 43 is slidably connected to the inner wall of the bearing hole 41. The surface of the support rod 43 is fixedly connected with the rotating plate 45. Two elastic pads 42 are fixedly installed on the surface of the rotating plate 45, and the surface of the elastic pad 42 is slidably connected to the inner wall of the rectangular hole 44.

The elastic pad 42 can also assist the staff to rotate the rotating plate 45.

[0032] Working principle: After installing the bolt assembly, pull the connecting block 303. The connecting block 303 slides away from the nut 2. While the connecting block 303 slides, it drives the short rod 312 to slide. While the short rod 312 slides, it drives the elastic sleeve 308 to slide. After the elastic sleeve 308 slides a certain distance, the elastic sleeve 308 slides out of the inner wall of the mounting hole 311. Then rotate the connecting block 303. While the connecting block 303 slides, it drives the short rod 312 to rotate. After the short rod 312 rotates a certain angle, stop rotating the connecting block 303. Then insert a tool into the inner wall of the connecting groove 310. Then rotate the tapered rod 309 by means of the connecting groove 310. The tapered rod 309 moves in the direction close to the screw 1 by means of the thread. After the tapered rod 309 moves a certain distance, the surface of the tapered rod 309 presses against the thread of the screw 1. At this time, the nut 2 is limited on the screw 1. Then rotate the connecting block 303. While the connecting block 303 slides, it drives the short rod 312 to rotate. After the short rod 312 rotates back to its original position, stop rotating the connecting block 303. Then release the connecting block 303. At this time, the push cylinder 306 can move away from the fixed plate 301 under the elastic force of the spring 305. While the push cylinder 306 moves, it drives the push cylinder 306 to move. While the push cylinder 306 moves, it drives the round rod 302 to move. While the round rod 302 moves, it drives the connecting block 303 to move. While the connecting block 303 moves, it drives the short rod 312 to move. While the short rod 312 moves, it drives the elastic sleeve 308 to move. After the elastic sleeve 308 moves a certain distance, the elastic sleeve 308 blocks the mounting hole 311 on the nut 2, so that dust will not block the mounting hole 311 and the connecting groove 310. By setting the limiting structure 3, after installing the bolt, the nut 2 can be limited on the screw 1, so that the nut 2 will not fall off the screw 1, improving the stability of the bolt.

[0033] When there is no tool to disassemble the bolt assembly, slide and rotate the rotating plate 45 by means of the support rod 43. After the rotating plate 45 slides a certain distance, stop sliding the rotating plate 45. Then rotate the elastic pad 42 to rotate the rotating plate 45. While the rotating plate 45 rotates, it drives the screw 1 to rotate, achieving the effect of assisting in rotating the screw 1, so as to disassemble the bolt assembly. By setting the auxiliary structure 4, the staff can rotate the screw 1 without tools, thus facilitating the staff to disassemble the bolt.
