[0034] Detailed description of the method of use: In the present invention, when the bolt loosening detection device needs to be used to detect the tightness of the bolt, first move the connecting tube 1 to drive the clamping plate 307, place the bolt in the middle of several clamping plates 307, then start the electric push rod 302 to drive the slip ring 301, so that the slip ring 301 moves along the arc surface of the round block 12, and the slip ring 301 drives several top plates 303, so that the oblique waist side of the top plate 303 presses the oblique waist side of the adjusting plate 306, and the adjusting plate 306 drives the positioning plate 305, so that the positioning plate 305 moves along the positioning rod 30 The side of 4 drives the clamping plate 307 to move in the direction close to the bolt. When the clamping plate 307 drives the rubber pad 308 to abut against the bolt, the clamping limit of the bolt can be completed. Then the controller 6 is operated to start the servo motor 7. The servo motor 7 drives the active roller 9 to rotate. The active roller 9 drives the driven roller 11 to rotate with the help of the belt 10. The driven roller 11 drives the rotating rod 2. The rotating rod 2 drives the round block 12 and the clamping plate 307 to rotate, so that the clamping plate 307 drives the bolt. When the bolt rotates, the rotating rod 2 will drive the rotating plate 5 to rotate. At this time, the personnel can Whether the rotating plate 5 rotates can be used to judge whether the bolt is loose. When the rotating plate 5 rotates, it means that the bolt is in a loose state at this time. It only needs to continuously drive the servo motor 7 to drive the clamping plate 307 to rotate, and the clamping plate 307 drives the bolt to tighten the bolt. When the bolt is tightened, the electric push rod 302 is started to drive the slip ring 301 to move in the opposite direction, and the slip ring 301 drives the top plate 303. At this time, the positioning block 310 on the top plate 303 will move along the inner wall of the positioning hole 309, and the positioning block 310 will use the positioning hole 309 to drive the adjustment plate 306 and the top plate 303 to move synchronously The top plate 303 drives the positioning plate 305, and the positioning plate 305 drives the clamping plate 307 to separate from the bolt, thereby completing all the steps of the bolt loosening detection operation.

[0035] When the block 12 is adjusted to a suitable position, the adjusting ring 45 is rotated with the help of the anti-slip grooves 47 so that the adjusting ring 45 can move along the arc surface of the slide bar 44 and drive the gasket 46 to separate from the connecting plate 42. When the gasket 46 is separated from the connecting plate 42, the block 12 is pulled to drive the connecting rod 41. At the same time, the block 12 can drive the connecting plate 42 to move the slide bar 44 along the inner wall of the sliding hole 43 on the connecting plate 42. When the block 12 is adjusted to a suitable position, the adjusting ring 45 is rotated with the help of the anti-slip grooves 47 so that the adjusting ring 45 drives the gasket 46 to abut against the connecting plate 42, thereby completing the position limitation of the block 12 and the splint 307. Among them, the gasket 46 can increase the friction force of the adjusting ring 45 close to the connecting plate 42, thereby achieving the effect of making the adjusting ring 45 abut against the connecting plate 42 with the help of the gasket 46.
