[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model provides a technical solution: Figures 1-6 The anti-loosening screw with a connecting assembly shown in the figure includes a screw rod 1, a sliding groove 12 is opened inside the screw rod 1, a telescopic groove 3 is opened at the bottom of the screw rod 1, a telescopic block 4 is slidably connected inside the telescopic groove 3, a protrusion 5 is arranged above the telescopic block 4, and the protrusion 5 is arranged in a "V" shape. An extension port 6 is opened on the outside of the screw rod 1 near the top of the protrusion 5, and the extension port 6 is connected to the sliding groove 12. A reset block 7 is arranged between the protrusions 5, and the top of the reset block 7 is rotatably connected to a rotating rod 8, and the rotating rod 8 is rotatably connected to the inner side of the screw rod 1 near the top.

[0025] During operation, the screw 1 is rotated into the fixed threaded hole, and the protrusion inside the threaded hole will push the telescopic block 4, and the telescopic block 4 will slide inside the telescopic groove 3 opened in the screw 1, so that the telescopic block 4 pushes the protrusion 5, so that the protrusion 5 slides along the sliding groove 12. When the sliding groove 12 reaches the position of the extension port 6, it will protrude from both ends, so that the protrusion 5 fixes the screw 1 again, thereby achieving a double fixation effect. When disassembly is required, the rotating rod 8 is rotated to press the reset block 7 downward, so that the reset block 7 pushes the protrusion 5 to make the protrusion 5 fall out of the extension port 6. At this time, the screw 1 can be rotated to take out the screw 1, which solves the problem of looseness caused by single rotation fixation in the past and improves the stability after fixation.

[0026] The reset block 7 is arranged in an inverted trapezoidal shape, the top position of the protrusion 5 close to the reset block 7 is rounded, a lifting assembly is arranged on the top of the rotating rod 8, the lifting assembly includes a rotating sleeve 10, the rotating sleeve 10 is fixedly connected to the top of the rotating rod 8, a fitting opening 11 is opened on the top of the rotating sleeve 10, a nut 2 is fixedly connected to the top of the screw rod 1, an insertion groove 9 is opened on the top of the nut 2, and the rotating sleeve 10 is rotatably connected inside the insertion groove 9.

[0027] During operation, insert the wrench into the nut 2 along the insertion slot 9, embed the wrench into the fitting opening 11, rotate the wrench to drive the rotating sleeve 10 to rotate, so that the rotating sleeve 10 drives the rotating rod 8 to rotate inside the screw rod 1, and the rotating rod 8 controls the lifting position of the reset block 7. After fixation, the nut 2 can be rotated to drive the screw rod 1 to rotate, so as to install and fix the screw rod 1. When the rotating rod 8 drives the reset block 7 to press the convex block 5, the convex block 5 disengages from the outlet 6. At this time, the screw rod 1 can be manipulated by the nut 2 for disassembly or installation, solving the problem of looseness after installation caused by a single clamping structure and improving the convenience of disassembly.

[0028] The nut 2 is hexagonal. An expansion and contraction assembly is arranged above the expansion and contraction block 4. The expansion and contraction assembly includes a spring 15. The top of the spring 15 is fixedly connected with a pushing block 16. The pushing block 16 abuts against the bottom of the convex block 5. The outside of the pushing block 16 is slidably connected with a sleeve 14. The sleeve 14 is fixedly connected to the top of the expansion and contraction block 4. The spring 15 is arranged inside the sleeve 14 and is fixedly connected to the top of the expansion and contraction block 4. A limiting assembly is arranged outside the screw rod 1. The limiting assembly includes a sliding plate 13. There are two groups of sliding plates 13 symmetrically fixed outside the expansion and contraction block 4. The sliding plate 13 is slidably connected inside the sliding groove 12.

[0029] During operation, due to the rotatable structure of the nut 2, the nut 2 can drive the screw rod 1 to rotate, so as to achieve the effect of installation or disassembly. When the rotating rod 8 is rotated to drive the reset block 7 to press down, the convex block 5 will press the pushing block 16, causing the pushing block 16 to press the spring 15 and the spring 15 to contract. At this time, the pushing block 16 will contract along the inner wall of the sleeve 14, so that the convex block 5 can be disengaged from the outlet 6, thus achieving the effect of disassembling the screw rod 1. When the reset block 7 disengages, the expansion and contraction block 4 will push the spring 15 and the pushing block 16 to drive the convex block 5 to protrude from the outlet 6. When the expansion and contraction block 4 moves up and down, the sliding plate 13 can slide inside the sliding groove 12, so as to limit the expansion and contraction block 4.

[0030] Working principle: Insert the screw 1 into the fixed threaded hole. The protrusions inside the threaded hole will push the telescopic block 4, and the telescopic block 4 will slide inside the telescopic groove 3 opened on the screw 1, enabling the telescopic block 4 to push the convex block 5, so that the convex block 5 slides along the inside of the sliding groove 12. When the sliding groove 12 reaches the position of the outlet 6, it will protrude from both ends, allowing the convex block 5 to fix the screw 1 again, thus achieving the effect of double fixation. When disassembly is required, rotate the rotating rod 8 to press down the reset block 7, so that the reset block 7 pushes the convex block 5 to disengage the convex block 5 from the outlet 6. At this time, the screw 1 can be rotated to remove the screw 1, solving the problem of loosening caused by single rotational fixation in the past and improving the stability after fixation. Insert the wrench into the nut 2 along the insertion groove 9, embed the wrench into the fitting opening 11, rotate the wrench to drive the rotating sleeve 10 to rotate, so that the rotating sleeve 10 drives the rotating rod 8 to rotate inside the screw 1, and the rotating rod 8 controls the lifting position of the reset block 7. When the fixation is completed, the nut 2 can be rotated to drive the screw 1 to rotate, thereby installing and fixing the screw 1. When the rotating rod 8 drives the reset block 7 to squeeze the convex block 5, the convex block 5 disengages from the outlet 6. At this time, the screw 1 can be manipulated through the nut 2 for disassembly or installation, solving the problem of loosening after installation caused by a single clamping structure and improving the convenience of disassembly. Due to the rotatable structure of the nut 2, the nut 2 drives the screw 1 to rotate, thereby achieving the effect of installation or disassembly. When rotating the rotating rod 8 to drive the reset block 7 to press down, the convex block 5 will squeeze the push block 16, causing the push block 16 to squeeze the spring 15 and making the spring 15 contract. At this time, the push block 16 will contract along the inner wall of the sleeve 14, so that the convex block 5 can be disengaged from the outlet 6, thus achieving the effect of removing the screw 1. When the reset block 7 disengages, the telescopic block 4 will push the spring 15 and the push block 16 to drive the convex block 5 to protrude from the outlet 6. When the telescopic block 4 moves up and down, the sliding plate 13 can slide inside the sliding groove 12, thereby restricting the telescopic block 4.
