Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
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 embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-3, a kind of coiled hair fastening screw, including screw terminal 1 are please referred to, the middle position at 1 top of screw terminal is successively
A word groove 2 and hexagonal indentations 3 are provided with, the two sides of screw terminal 1 are all provided with short handle 4, the bottom end setting in 1 outside of screw terminal
There is a limited block 5, the bottom of screw terminal 1 is provided with screw rod 6, the top in 6 outside of the screw rod and bottom for being located at screw terminal 1 is provided with pad
Circle 7, the outside of screw rod 6 is provided with the first external screw thread 8.
The utility model is by being all arranged short handle 4 in the two sides of screw terminal 1, when manually being tightened, can pass through two groups
Short handle 4 carries out the phenomenon that borrowing power, being not in skidding between hand and screw terminal 1, tightens fixed effect to can reach, real
Stronger with property, by the way that a word groove 2 and hexagonal indentations 3 is arranged at the top of screw terminal 1, and a word groove 2 and hexagon are recessed
Slot 3 is not interfere with each other, and when tightening screw, not only the bottom end of manifold screwdriver can be caught in one by manifold screwdriver
In word groove 2, being tightened with auxiliary, when can not find screwdriver, also the bottom end of interior six side can be sticked into hexagon by interior six side
In groove 3, tightened with auxiliary, utilization is more flexible.
Fig. 1, Fig. 2 and Fig. 3 are please referred to, the two sides of screw terminal 1 are all provided with threaded hole 9, and one end of told short handle 4 is provided with
With mutually matched second external screw thread 10 of threaded hole 9, short handle 4 is detachably connected with screw terminal 1, and the utility model passes through setting phase
The threaded hole 9 and the second external screw thread 10 mutually cooperated can be by short handle 4 and screw under the action of threaded hole 9 and the second external screw thread 10
