[0024] The anti-slip fastening assembly 1 includes a nut body 101, through which a plurality of horizontal fastening rods 102 evenly distributed in an annular shape are passed, and a plurality of horizontal through holes adapted to the horizontal fastening rods 102 are provided on the nut body 101, and the horizontal fastening rods 102 pass through the horizontal through holes on the nut body 101, and the horizontal fastening rods 102 are used in conjunction with the horizontal through holes on the nut body 101, and a plurality of vertical guide columns 103 are fixedly installed on the upper surface of the nut body 101, and a circular top plate 104 is fixedly installed on the top of the vertical guide column 103, and an annular lifting plate 105 is slidably sleeved on the outer side of the vertical guide column 103, and a vertical guide column 103 adapted to the vertical guide column 103 is provided inside the annular lifting plate 105. The vertical guide column 103 passes through the vertical guide hole on the annular lifting plate 105, and the vertical guide column 103 and the vertical guide hole on the annular lifting plate 105 are slidably matched. A return spring 106 is sleeved on the outer side of the vertical guide column 103 and located between the upper surface of the nut body 101 and the lower surface of the annular lifting plate 105. The upper surface of the outer end of the horizontal fastening rod 102 is movably connected to the side of the annular lifting plate 105 through a connecting inclined rod 107. One end of the connecting inclined rod 107 is rotatably matched with the upper surface of the outer end of the horizontal fastening rod 102 through a hinge seat, and the other end of the connecting inclined rod 107 is rotatably matched with the side of the annular lifting plate 105 through another hinge seat. A limiting hole 108 is provided on the annular lifting plate 105;
[0025] The limiting assembly 2 includes a strip rotating plate 201, the bottom of which is rotatably connected to a T-shaped shaft 202, which is fixedly mounted on one side of the nut body 101, and a U-shaped bracket 203 is fixedly mounted on the top of the strip rotating plate 201, a limiting column 204 is passed through the interior of the U-shaped bracket 203, the inner end of the limiting column 204 passes through the strip rotating plate 201, and the inner end of the limiting column 204 is inserted into the corresponding limiting hole 108, an annular baffle 205 is fixedly sleeved on the middle of the limiting column 204, a telescopic spring 206 is sleeved on the outer surface of the limiting column 204 and located between the U-shaped bracket 203 and the annular baffle 205, and a fixed pull ring 207 is fixedly mounted on the outer end of the limiting column 204;

At this time, the telescopic spring 206 will shrink and shorten, and the inner end of the limiting column 204 will move out from the limiting hole 108, and the limiting column 204 will not The annular lifting plate 105 is limited again. At this time, due to the elastic force of the return spring 106, the annular lifting plate 105 will be squeezed and move upward. Since the upper surface of the outer end of the horizontal fastening rod 102 is movably connected to the side of the annular lifting plate 105 through the connecting oblique rod 107, when the annular lifting plate 105 moves upward, several horizontal fastening rods 102 will gather inward at the same time. At this time, the inner end of the horizontal fastening rod 102 will be squeezed on the threaded rod, thereby forming a fastening to prevent the nut body 101 from falling off.
