Detailed description of the invention
Being specifically described this utility model below in conjunction with the accompanying drawings, as shown in Figure 1-2, a kind of novel screw, including nail
Body 1, described rivet nut 1 is provided with external screw thread 2, and described rivet nut 1 one end is provided with ailhead 3, and the cross section of described ailhead 3 is tetragon, institute
The multiple side surfaces stating ailhead 3 are equipped with protruding 4, and described ailhead 3 is set with expanding sheath 5, and described expanding sheath 5 one end has ten
Word groove 6, described expanding sheath 5 inner surface has multiple groove 7；Described groove 7 and protruding 4 shapes, size matches；Described
Centered by expanding sheath 5, position has the round table-like structure of rectangular channel 8.
The feature of the present embodiment is, rivet nut 1 is provided with external screw thread 2, and rivet nut 1 one end is provided with ailhead 3, the cross section of ailhead 3
For tetragon, multiple side surfaces of ailhead 3 are equipped with protruding 4, ailhead 3 are set with expanding sheath 5, and expanding sheath 5 one end has ten
Word groove 6, expanding sheath 5 inner surface has multiple groove 7, and simple in construction is easy to use, good fixing effect, practical, has
Novelty.
In the present embodiment, hand-held rivet nut 1 one end, the ailhead 3 being located at rivet nut 1 one end is inserted expanding sheath 5 centre bit
In the rectangular channel 8 put, and the projection 4 of ailhead 3 is made to be embedded into the groove of expanding sheath 5, so that rivet nut 1 is fixed on expansion head,
It is buckled in cross recess 6 with instrument again and screw is hammered into desired location, this screw, exert a force during use little, and simple in construction, user
Just, good fixing effect, practical, there is novelty.
Technique scheme only embodies the optimal technical scheme of technical solutions of the utility model, the technology of the art
Some variations that some of which part may be made by personnel all embody principle of the present utility model, belong to this utility model
