The fixed block 602 is fixedly connected to the bottom of the connecting member 1. A mounting groove 603 is provided inside the fixed block 602. The circular plate 604 is arranged inside the mounting groove 603. The slider 605 is symmetrically fixedly connected to the upper and lower sides of the circular plate 604. The positioning column 607 is fixedly connected to one side of the circular plate 604, and the positioning column 607 extends out from the side of the fixed block 602 close to the nut 5. The first spring 606 is fixedly connected between the side of the circular plate 604 away from the positioning column 607 and the inner wall of the mounting groove 603.

[0026] Further as Figure 1 、 Figure 2 and Figure 3 As shown, it is worth noting that a sliding groove adapted to the slider 605 is provided inside the mounting groove 603;

[0027] The slider 605 is provided to slide inside the slide groove, thereby stably driving the circular plate 604 to slide inside the installation groove 603, thereby ensuring the stability of the movement of the positioning column 607.

[0028] Further as Figure 1 、 Figure 2 and Figure 3As shown, it is worth noting that the outer portion of the nut 5 is evenly provided with positioning grooves 601, and the size of the positioning column 607 is adapted to the positioning groove 601;

[0029] The provided positioning groove 601 can limit the nut 5 rotated to various angles, thereby improving the practicality of the mechanism.

[0030] Further as Figure 1 、 Figure 2 and Figure 3 As shown, it is worth noting that the push block 608 is fixedly connected to the front of the circular plate 604, and the front of the mounting groove 603 is provided with a through slot for the push block 608 to slide, and the limiting component 609 is arranged above the side of the through slot away from the nut 5.

[0031] According to the above working process, it can be known that: through the fastening mechanism 6, the positioning column 607 can be inserted into the positioning groove 601 set on the outside of the nut 5 to fix the position of the nut 5, thereby locking the nut 5 to prevent the nut 5 from loosening, thereby improving the fastening ability and anti-slip performance of the nut 5 and avoiding the problem of loosening or falling off.

[0032] Further as Figure 2 、 Figure 3 and Figure 4 As shown, it is worth mentioning that the limiting assembly 609 is composed of a fixed plate 6091, a vertical rod 6092, a baffle 6093, a lifting plate 6094 and a second spring 6095. The fixed plate 6091 is fixedly connected to the front of the fixed block 602, the vertical rod 6092 is slidably connected to the inside of the fixed plate 6091, the baffle 6093 is fixedly connected to the top surface of the vertical rod 6092, the second spring 6095 is fixedly connected between the baffle 6093 and the fixed plate 6091, and the second spring 6095 is sleeved on the outside of the vertical rod 6092.

[0033] Further as Figure 2 、 Figure 3 and Figure 4 As shown, it is worth noting that the lifting plate 6094 is fixedly connected to the top surface of the baffle 6093;

[0034] The provided lifting plate 6094 can facilitate the user to pull the lifting plate 6094 upwards, thereby driving the bottom end of the vertical rod 6092 to be pulled out from the inside of the limiting groove 6096, thereby improving the convenience of using the mechanism.

[0035] Further as Figure 2 、 Figure 3 and Figure 4 As shown, it is worth noting that the top surface of the push block 608 is provided with a limiting groove 6096 adapted to the vertical rod 6092, and one side of the vertical rod 6092 is provided with an arc surface;

[0036] Through the provided arcuate surface, when the fixation of the positioning column 607 on the nut 5 is released, the push block 608 is pushed to the side away from the nut 5. When the arcuate surface contacts the vertical rod 6092, the vertical rod 6092 is squeezed to move it upward until the push block 608 moves to the limiting groove 6096 and is below the vertical rod 6092. The vertical rod 6092 is reset by the elastic action of the second spring 6095, so that the vertical rod 6092 is inserted into the limiting groove 6096 to fix the position of the push block 608.

[0037] This solution has the following working process: when in use, the washer 4 is placed between the nut 5 and the connecting member 1, and the lifting plate 6094 is pulled upward to drive the vertical rod 6092 to move, so that it disengages from the inside of the limit groove 6096, releasing the position fixation of the push block 608. At the same time, under the elastic action of the first spring 606, the circular plate 604 is driven to move, and the positioning column 607 is driven to move so that it is inserted into the inside of the positioning groove 601, thereby fixing the position of the nut 5 and making it stably installed under the connecting member 1. Then, the bolt 2 is screwed into the inside of the connecting member 1, the washer 4, and the nut 5 in turn, and the installation of the bolt 2 is tightened through the cross groove 3 above. At the same time, the fastening mechanism 6 below fixes the position of the nut 5, thereby locking the nut 5 and preventing the nut 5 from loosening, thereby improving the fastening ability and anti-falling performance of the nut 5 and avoiding the problem of loosening or falling off.

[0038] When the nut 5 needs to be replaced, the push block 608 is pushed toward the side away from the nut 5. When it contacts the curved surface of the vertical rod 6092, the vertical rod 6092 is squeezed to move it upward until the push block 608 moves to the limit groove 6096 and is below the vertical rod 6092. The vertical rod 6092 is reset by the elastic action of the second spring 6095, so that the vertical rod 6092 is inserted into the inside of the limit groove 6096, fixing the position of the push block 608 and completely releasing the connection between the positioning column 607 and the nut 5. The nut 5 can then be disassembled and replaced.

[0039] In summary: through the provided fastening mechanism 6, the positioning column 607 can be inserted into the positioning groove 601 provided on the outside of the nut 5 to fix the position of the nut 5, thereby locking the nut 5 and preventing the nut 5 from loosening, thereby improving the fastening ability and anti-slip performance of the nut 5 and avoiding the problems of loosening and falling off; through the provided limiting component 609, the vertical rod 6092 can be inserted into the limiting groove 6096 to limit the position of the positioning column 607, and release the fixing of the positioning column 607 on the nut 5, thereby facilitating the disassembly of the nut 5 from the bottom of the connecting member 1, facilitating the disassembly and replacement of the nut 5, and improving the practicality of the structure.
