Embodiment Construction

[0011] The following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0012] see figure 1 , the embodiment of the present invention includes:

[0013] A waterproof screw, comprising: a screw body 1, a waterproof section 2 and a tapping section 3.

[0014] The waterproof section 2 is connected to the tail end of the screw body 1, and the tapping section 3 is connected to the tail end of the waterproof section 2. Both the waterproof section 2 and the tapping section 3 are cylindrical, so The cross-sectional diameter of the attacking section 3 is greater than or equal to the cross-secti...
