Abstract

The invention discloses a wave plate screw assembly. The wave plate screw assembly is mainly characterized in that a rod body of a locking part is provided with at least two propping parts; meanwhile, a broaching part is provided with clamping points; in the locking process, the broaching part can be stably and effectively driven to rotate by the locking part through clamping of the propping parts and the clamping points; the cutting capacity and effect of the broaching part are improved; when the propping parts are clamped onto the clamping points, the broaching part can be effectively corrected, and the condition that the broaching part is likely to skew when screwed in is eliminated.

Description

technical field [0001] The invention relates to the technical field of screws, in particular to a corrugated plate screw assembly. Background technique [0002] refer to figure 1 The known corrugated plate screw 1 includes a rod body 11, a screw head 12 provided at one end of the rod body 11, and a locking portion 13 opposite to the screw head 12 and provided at the other end of the rod body 11; wherein, the rod body 11 There are two symmetrically arranged hole reamers 111 and a plurality of circumferentially arranged screw teeth 112 , and the aforementioned hole reamer members 111 are symmetrically arranged between the screw teeth 112 and the screw head 12 . When locking, use the locking part 13 and these screw teeth 112 to screw into the corrugated board A and the skeleton B, and at the same time, these hole reaming parts 111 cut a rotary cutting hole larger than the diameter of the rod body 11 on the corrugated board A, so that An appropriate gap is generated between th...
