Embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained, shall fall within the protection scope of the present invention.
- 3 are please referred to Fig.1, a kind of embodiment provided by the utility model：A kind of outer-hexagonal bolt, including rounded stops 1,
First bolt head 2, gear 5, packing ring 7, thread screw 9, filled cavity 12 and threading hole 14, rounded stops 1 are coated with bag
Glue 4, rounded stops 1 are provided with two pieces altogether, and on 2 distribution in a center of symmetry of the first bolt head, and the surface of rounded stops 1 is opened
Equipped with hexagon ring so that hexagonal cavity 3 is unobstructed, and the inside of the first bolt head 2 is inlaid with hexagonal cavity 3, the first bolt head 2
It is regular hexagon structure with the second bolt head 6, and the circumcenter of the first bolt head 2 and the circumcenter of the second bolt head 6
Overlap so that the first bolt head 2 frictional force smaller when rotating, is connected with the second bolt head 6, tooth at the right side port of gear 5
The outer wall of wheel 5 is provided with circle strip clockwise, and the strip is mutually closely connected with the inner wall of the first bolt head 2 so that gear 5
It can only rotate clockwise, and the right side of the second bolt head 6 is provided with flange gasket 15, the right of packing ring 7 is provided with smooth surface screw rod 8,
Length ratio between smooth surface screw rod 8 and thread screw 9 is 1:2, and smooth surface screw rod 8 is integral structure with thread screw 9 so that
The intensity increase of the outer-hexagonal bolt, and the inside of smooth surface screw rod 8 is interspersed with newel 13, the surface engraving of thread screw 9 has
Screw thread 11, and the bottom of thread screw 9 is equiped with bar tail 10, bar tail 10 includes bar tail sleeve 101 and tail pad 102, and bar tail 10 falls
