Description of the embodiments
Embodiments of the present utility model will be further described with reference to fig. 1 to 5.
The specific structure of the embodiment is as follows: the screw comprises a cylindrical screw 1 and a tip 2 at one end of the screw 1, wherein the other end of the screw 1 opposite to the tip 2 is provided with a tip 11, and the peripheral wall of the screw 1 is provided with threads. The peripheral wall between the root 12 and the tip 2 of the screw 1 is provided with a number of fine threads 13.
The end head 2 comprises an integrally formed force application part 21 and a limiting part 22, wherein the limiting part 22 is arranged at one end of the force application part 21, the diameter of the limiting part 22 is larger than that of the force application part 21, the limiting part 22 is in a flat disc shape, a cross groove 210 is formed in the center of the force application part 21, the outer peripheral wall of the force application part 21 is in a hexagon shape, after a screw driver stretches into the cross groove 210 to twist a screw and connect with a wooden plate body B, the screw driver can be sleeved outside the force application part 21 through a hexagonal wrench to twist again, so that the end part is further extruded towards the direction of the angle steel A, and the connection strength is improved.
