Anti-slip screw

The anti-slip screw comprises a screw rod, the front face of the screw rod is connected with a control structure, the control structure comprises an edge block, notches, a vertical rod and a circular plate, the rear end face of the edge block and the front face of the screw rod are integrally formed, the notches are machined in the outer wall of the edge block at equal intervals, and the vertical rod is connected with the notch. According to the anti-slip screw, the vertical rod in the control structure is inserted into the notch, then the vertical rod is held to rotate, and then the edge block is driven to rotate through the notch, so that the screw is normally used and is convenient to screw; and the use limitation is eliminated. 本实用新型公开了一种防滑脱螺钉，包括螺杆，所述螺杆的正面连接有控制结构，所述控制结构包括棱块、槽口、竖杆和圆板，所述棱块的后端面与螺杆的正面一体成型，所述棱块的外壁等距加工有槽口，位于顶部所述槽口的内壁与竖杆的外壁底部相插接，所述棱块的正面与圆板的后端面相固接，该防滑脱螺钉，通过控制结构中竖杆插入槽口的内部，然后握住竖杆转动，进而通过槽口带动棱块转动，使螺钉正常使用，旋拧方便，消除了使用局限性。
