[0014] The utility model provides a special-shaped screw. Compared with the prior art, it has the following beneficial effects:
[0015] 1. This special-shaped screw rod is screwed into the groove hole by screwing the fixed rod body into the groove hole, and the fixed threaded rod body is rotated with the fixed rod body, so that the fixed threaded rod body is screwed into the bottom groove. The fixed threaded rod body and the fixed rod body are double fixed, so that the special-shaped barb can be stably fixed and connected. The user needs to replace the special-shaped barb with different curvatures, and the barb with different curvatures is replaced by rotating for fixed use, thereby avoiding the need to purchase a variety of barbs with different curvatures to meet actual needs due to the inability to adjust the curvature of the barb. The inventor believes that the above problems can be solved by replacing barbs with different curvatures, and the problem of reducing the material cost of the enterprise can also be reduced.
