Detailed Description

The present application is described in further detail below with reference to figures 1-3.

Example 1:

the embodiment of the application discloses a titanium alloy bolt. Referring to fig. 1, the titanium alloy bolt comprises a nut 1 and a screw 2, wherein one side of the nut 1 is integrally connected with one end face of the screw 2; the horizontal cross section of nut 1 is regular hexagon, has seted up hexagon socket hole 3 in the upper surface of nut 1, and hexagon socket hole 3 can cooperate with interior hexagonal spanner.

Each inner wall of the hexagon socket 3 is parallel to each outer side wall of the nut 1 correspondingly, each outer side wall of the nut 1 is provided with a threaded hole 4, the threaded hole 4 penetrates into the hexagon socket 3 from the outer side of the nut 1, and a support rod 5 is screwed on the threaded hole 4; when wearing and tearing and the side of sliding take place for certain one side of interior hexagonal hole 3, can be at this side spiro union bracing piece 5 for on the outside of hexagon spanner including one side butt of bracing piece 5, it is spacing to carry out interior hexagon spanner, make can not take place relative slip between interior hexagon spanner and the nut 1, can drive nut 1 and rotate, realize conveniently wearing and tearing and the interior hexagon bolt of side of sliding to interior hexagonal hole 3 and rotate and take out.
