Cooperation between limiting slot further ensures good bonding strength and stability.
The utility model is further arranged to：The limit section is equipped with several limiting tooths, and the both sides of limiting tooth are equipped with
Supporter, supporter include the joint face A being connect with limiting tooth, with limit section outer wall the joint face B and supporting surface that connects, prop up
Support face is in arc-shaped, and the opening direction of circular arc is towards outside limiting tooth.
By using above-mentioned technical proposal, limit section is equipped with several limiting tooths, in order to improve the structure of each limiting tooth
Intensity by being respectively equipped with supporter in the both sides of each limiting tooth, and supporter is set as including connecting with limiting tooth
Joint face A, the joint face B and supporting surface being connect with limit section outer wall, by the basis that is connected to of joint face A, B, and lead to
It crosses supporting surface to be supported, improves structural strength, further set supporting surface to be in arc-shaped so that supporter is limiting
The support effect that arc structure is provided between tooth and limit section outer wall, by the opening direction of circular arc towards outside limiting tooth, equally
So that force localization of the limiting tooth in stress is on supporter.
The utility model is further arranged to：The thread segment is equipped with chrome layer, and chromium plating layer thickness is 0.03-
0.05mm。
By using above-mentioned technical proposal, thread segment is equipped with chrome layer, and chromium plating layer thickness is 0.03-0.05mm, according to
Long-term use finds, by chrome layer in it is deep-controlled in 0.03mm hereinafter, the structural strength that can reinforce to thread segment is inadequate
Greatly, it if by the deep-controlled in 0.05mm or more of chrome layer, although the structural strength of thread segment can be improved, be easy to cause pair
In the abrasion of nut or other connectors, to influence stability when connection, and cost can be increased, so by chromium plating
Layer it is deep-controlled between 0.03-0.05mm, the effect reached is best.
