Clamping, by contractility and the frictional force of torsion spring, so as to prevent nut loosening, so that reach locking purpose.Additionally, due to
The initiating terminal of torsion spring stretches out loose slot, compares manual toggle initiating terminal and there is pain, be thus provided with rotation ring, by revolve ring come
Initiating terminal is stirred, so as to the point contact in operating process is converted to face contact, so as to improve affected comfort level, reduces pain
Sense.
Can be preferably as concrete scheme of the present utility model：The side wall of the rotation ring is provided with non-slip texture.
By above-mentioned setting, the frictional force of finger contact rotation ring is improved, prevents from skidding.
Can be preferably as concrete scheme of the present utility model：The outer end of the rotation ring is provided with elastic ring, the elasticity
Axial movement of the snare located at the side wall spacing rotation ring of light hole section.
By above-mentioned setting, elastic ring is tightened up in light hole section so that rotation ring can not come off from light hole section, and revolve ring
Can be rotated in light hole section, such that it is able to drive initiating terminal action.
Can be preferably as concrete scheme of the present utility model：The outer face of the thread segment is provided with cannelure, institute
State cannelure and be embedded with Magnet.
By above-mentioned setting, Magnet is embedded in cannelure, when tightening nut is carried out, as Magnet has magnetic
And nut can be magnetized, can adsorb on bolt from what, for some eminence installation sites, nut is easy in installation process
Drop, by the absorption of Magnet, can effectively prevent nut from dropping, be easy to user that quickly nut is nested on bolt.
Can be preferably as concrete scheme of the present utility model：The non-slip texture is circumferentially divided uniformly around rotation ring for some
The strip bulge of cloth.
By above-mentioned setting, relatively simple for structure, the easily enforcement of strip bulge, and the skidding of finger can be prevented.
In sum, this utility model has the advantages that：
1st, it is more convenient than relatively labor-saving to operate, and will not injure finger；
2nd, installation is more convenient, can be positioned and be adsorbed.

Specific embodiment
This utility model is described in further detail below in conjunction with accompanying drawing.
Embodiment 1：As shown in Figure 1-2, a kind of stop nut, nut body 2 include thread segment 22 and light hole section 21, screw thread
Section 22 has one section of female thread such as hex nut, and light hole section 21 has through hole of one section of internal diameter more than internal thread diameter, through hole
Interior torsion spring 3 can be installed, the trend of torsion spring 3, internal diameter, pitch and female thread are consistent, near interior on the side wall of light hole section 21
It is provided with loose slot 1 at screw thread, loose slot 1 is long waist shaped, the initiating terminal 31 of torsion spring 3 extends loose slot 1, the end end of torsion spring 3
32 are connected on the side wall of light hole section 21, are arranged with the rotation ring 4 around the rotation of 21 axis of light hole section, rotation on the lateral wall of light hole section 21
