Structure, the location structure are arranged at the top at embedment end.
Preferably, in above-mentioned technical proposal, specific structure be interior hexagonal structure, the dihedral symmetrical structure of tool or
Symmetrical structure with four planes.
Preferably, in above-mentioned technical proposal, location structure is cylinder, and location structure also includes head.
Preferably, in above-mentioned technical proposal, head is arranged to spherical or taper.
Preferably, in above-mentioned technical proposal, the middle part of middle light bar segment has knurling structure, and knurling structure is along middle light
The one of the axis direction setting of bar segment encloses tongue and groove in parallel to each other.
Preferably, in above-mentioned technical proposal, the embedment end of studs is identical with the screw thread specification of nut end, and is thick
Pitch thread.
Compared with prior art, the utility model has the advantages that：
(1) (can be by the mounting or dismounting tools of automation) be convenient to mount and dismount, are easy to maintaining；Assembly and disassembly efficiency is improved, is adapted to big
The demand of large-scale production；
(2) screw-down torque of the embedment end when being embedded to the main body of connector can be controlled；
(3) can be used cooperatively with existing standard part nut, product versatility is good；
(4) conventional mounting or dismounting tools can be used in mounting or dismounting tools, and without developing special tooling, product suitability is good.
(5) have what location structure can control stud to tighten depth, help to tighten the uniformity of depth.
(6) knurling structure of light bar segment causes studs equally to have advantage, the annular knurl when being tightened by hand among
Increasing friction force when structure is advantageous to tighten by hand, consequently facilitating operation.
