A fastener for preventing loosening includes: a fixing bolt 10 and a fixing block 20, wherein the inner side wall of the fixing block 20 is fixedly connected to the center of the outer edge of the fixing bolt 10, an adjustment component 30 is provided on the outer edge of the fixing bolt 10, and an anti-loosening component 40 is provided on the outer edge of the adjustment component 30;

[0023] The adjustment assembly 30 includes two adjustment rods 31 disposed on the outer edge of the fixing bolt 10. The adjustment rods 31 are each provided with a threaded hole 32 adapted to the fixing bolt 10 on one side thereof near the fixing bolt 10. A threaded rod 33 is rotatably provided on the inner side of each adjustment rod 31. An adjustment block 34 is sleeved on the outer edge of each threaded rod 33 and slidably connected thereto. A lifting block 35 is fixedly mounted on the left and right sides of each adjustment block 34. A positioning hole 36 is provided on the surface of each lifting block 35 near the center.

[0024] When the device is in use, one hand fixes the adjusting rod 31 and drives the fixing bolt 10 to rotate through the fixing block 20, so that the fixing bolt 10 is adjusted to a suitable position inside the threaded hole 32, and the distance between the two adjusting rods 31 is adjusted to a suitable position, thereby facilitating the device to tighten objects of different thicknesses and improving the practicality of the device.

[0025] The anti-fall-off assembly 40 includes a hexagonal nut 41 disposed on the outer edge of the adjustment rod 31. A sliding block 42 is slidably disposed on the inner side of the hexagonal nut 41. A sliding groove 43 is formed on the inner side of the hexagonal nut 41 for the sliding block 42 to slide left and right. A positioning rod 44 is provided inside the sliding groove 43 and is fixedly connected to the positioning hole 36. An elastic member 45 is provided inside the sliding groove 43 and on the outer edge of the positioning rod 44 to drive the sliding block 42 to slide.

[0034] The second step is to pass the adjusted rear fixing bolt 10 and the adjusting rod 31 through the object to be tightened, and the knob 38 is rotated by the tool, and the knob 38 drives the threaded rod 33 to rotate, and the threaded rod 33 drives the adjusting block 34 to move up and down, and the adjusting block 34 drives the lifting block 35 to move up and down inside the lifting port 37 to the set height, and pull the pulling block 46 outward, driving the positioning rod 44 to slide outward, and the positioning rod 44 drives the sliding block 42 to slide inside the sliding groove 43, and squeezes the elastic member 45, causing it to deform and shrink, and at the same time, causes the positioning rod 44 to shrink to the inside of the hexagonal nut 41, and the hexagonal nut 41 is threadedly connected to the surface of the two adjusting rods 31, and the positioning rod 44 is squeezed by the reaction force of the elastic member 45 to be inserted into the inside of the positioning hole 36, thereby restricting the hexagonal nut 41, reducing the possibility of loosening of the device, and increasing the overall practicality to adapt to use in a vibration environment.

[0035] Compared with the related art, the anti-loosening fastener provided by the utility model has the following beneficial effects:

[0036] By cooperating with each other in the various components of the device, the hexagonal nut 41 is threadedly connected to the surface of the two adjusting rods 31, and the positioning rod 44 is squeezed and inserted into the inner side of the positioning hole 36 by the reaction force of the elastic member 45, thereby restricting the hexagonal nut 41, reducing the possibility of loosening of the device, and increasing the overall practicality to adapt to use in a vibrating environment. In conjunction with the function of the adjustment component 30, the distance between the two adjusting rods 31 is adjusted to a suitable position, thereby facilitating the device to tighten objects of different thicknesses and improving the practicality of the device.
