Ball contacts, and the other side of spring is contacted with magnet.
In some embodiments, the rear end of bolt is equipped with limiting stand, longitudinal pin rod slot hole bottom to bolt distance from bottom
Less than pin rod to the distance of disk slot upper surface, the position of limiting stand is higher than at the top of longitudinal pin rod slot hole.
In some embodiments, the upper end left and right sides wall of bolt is equipped with anti-skidding stupefied.As a result, when operator is in bolt
When upper application pressure, due to bolt be equipped with it is anti-skidding stupefied, bolt is not easy to slip from operator's hand, also allow for dismounting when, facilitate behaviour
The upward plug pin of author.
In some embodiments, the end face of set screw is equipped with a word groove or cross recess.It is recessed that one word is set as a result,
Slot or cross recess facilitate the installation and removal of set screw.
Compared with prior art, the utility model has the beneficial effects that：The utility model is simple in structure, and longitudinal direction is set on bolt
Pin rod slot hole, pin rod are inserted in longitudinal pin rod slot hole, and definitely bolt is set without departing from pin hole, bolt and cross bar tapered end integration
Meter, component are not easy to lose, and whole installation process is quick, improve construction efficiency；In the side wall of bolt, compressible ball, rolling are set
Pearl contradicts with pin hole inner wall, and the sliding friction between bolt and pin hole is changed into rolling friction, reduces resistance when assembly
Power, to reach good labor-saving effect；After assembly in place, extensible member withstands ball, and ball withstands the inner wall of pin hole, bolt
It will not be slipped out of pin hole.
