Problems solved by technology

[0005] The purpose of the present invention is to solve the shortcomings in the prior art, such as: when the thickness of the two boards to be fastened is too large, the screw sleeve and the screw body are respectively inserted into the punching places of the two boards. At the beginning, there was a deviation in the alignment of the holes and the setting of the hole diameter was too large. The screw sleeve and the screw body may not be connected after a long time of orientation adjustment. Then a hexagon T-shaped butt screw body is proposed.

Abstract

The invention discloses an inner hexagonal T-shaped butt joint screw main body. The inner hexagonal T-shaped butt joint screw main body comprises a screw main body and a thread sleeve matched with thescrew main body, wherein an internal thread groove is arranged in the middle of the small head end of the thread sleeve; a butt-inserting ring groove arranged in the thread sleeve is arranged in theperiphery of the internal thread groove; a screw part matched with the internal thread groove is arranged at the small head end of the screw main body; an inserting groove, a limiting chute, an installing groove and a long hole are sequentially arranged in the screw main body in a communicating mode; a butt-inserting rod is inserted into the inserting groove in a sliding mode; and a rack plate isarranged in the limiting chute in a sliding mode. Through the effect of the butt-inserting rod longer than the screw part after extending out, butt insertion with the butt-inserting ring groove in theend of the thread sleeve can be achieved in advance and quickly, due to the fact that the area arranged in the circumferential direction of the butt-inserting ring groove is larger, butt insertion after finding is easier, and the thread sleeve can be centered by rotating the screw main body after butt insertion of the butt-inserting rod and the butt-inserting ring groove, the axis of the thread sleeve and the axis of the screw main body are located on the same line, and threaded connection assembly of the thread sleeve and the screw main body is greatly facilitated.
