[0025] Please see Figures 1-4 This utility model provides a novel screw with an anti-slip thread structure, including a screw assembly 100. The screw assembly 100 includes a first screw 101, an anti-slip thread sheet 102 fixedly connected to the upper end of the first screw 101, a plurality of first anti-slip thread engagement teeth 103 provided at the lower end of the anti-slip thread sheet 102, a first hexagonal head 104 fixedly connected to the upper end of the first screw 101, a second hexagonal head 105 sleeved on the side surface of the first hexagonal head 104, a first anti-slip ring 106 and a second anti-slip ring 107 respectively sleeved on the side surface of the first screw 101, a second anti-slip thread engagement tooth 108 provided on the opposite sides of the first anti-slip ring 106 and the second anti-slip ring 107, and a third anti-slip thread engagement tooth 109 and a fourth anti-slip thread engagement tooth 110 respectively provided on the opposite sides of the first anti-slip ring 106 and the second anti-slip ring 107.

[0026] In one specific embodiment, the tension generated by the screw assembly 100 through its components significantly enhances the anti-slip performance of the new screw, thereby improving its safety. During use, the first screw 101 is first threaded into the workpiece. As the first screw 101 penetrates deeper into the workpiece, the second anti-slip thread engagement tooth 108 at the lower end of the second anti-slip ring 107 embeds into the workpiece. Simultaneously, the first anti-slip thread engagement tooth 103 at the lower end of the anti-slip thread sheet 102 engages with the second anti-slip thread engagement tooth 108 at the upper end of the first anti-slip ring 106. At the same time, the third and fourth anti-slip thread engagement teeth 109 on the opposite surfaces of the first and second anti-slip rings 106 and 107 engage with... When the first screw 101 is in use, the longitudinal tension of the second anti-slip thread engagement tooth 108 at the lower end of the second anti-slip ring 107 can initially enhance the anti-slip thread performance. Combined with the tension of the third anti-slip thread engagement tooth 109 and the fourth anti-slip thread engagement tooth 110, it can prevent the relative rotation of the two, thereby significantly enhancing the anti-slip thread performance of the new screw and improving the safety of its use. When the second hexagonal head 105 is damaged at the edges, the first hexagonal head 104 can still allow the first screw 101 to be used, and at the same time facilitates the replacement of the second hexagonal head 105, thereby further enhancing the anti-slip thread performance of the new screw and improving its safety of use.

[0031] Please refer to Figures 3-4 The first anti-skid ring 106 and the second anti-skid ring 107 are both made of stainless steel.

[0032] In a specific embodiment, the first anti-skid ring 106 and the second anti-skid ring 107 made of stainless steel can avoid rust and prolong the service life.

[0033] Working principle: in use, first, the first screw 101 is threadedly connected inside the workpiece, and as the first screw 101 penetrates into the workpiece, the second anti-skid wire engagement tooth 108 at the lower end of the second anti-skid ring 107 is embedded in the workpiece, while the first anti-skid wire engagement tooth 103 at the lower end of the anti-skid wire piece 102 and the second anti-skid wire engagement tooth 108 at the upper end of the first anti-skid ring 106 are engaged, and the third anti-skid wire engagement tooth 109 and the fourth anti-skid wire engagement tooth 110 on the opposite faces of the first anti-skid ring 106 and the second anti-skid ring 107 are engaged. When the first screw 101 is used, the longitudinal tension of the second anti-skid wire engagement tooth 108 at the lower end of the second anti-skid ring 107 can preliminarily enhance the anti-skid wire performance, and the tension of the third anti-skid wire engagement tooth 109 and the fourth anti-skid wire engagement tooth 110 can prevent relative rotation, so as to significantly enhance the anti-skid wire performance of the new screw, thereby improving the use safety of the new screw. When the second hexagonal head 105 is damaged, the first hexagonal head 104 can still enable the first screw 101 to be used, and the second hexagonal head 105 can be replaced, thereby further enhancing the anti-skid wire performance of the new screw, thereby improving the use safety.
