As a kind of optimal technical scheme of the utility model, corresponds on the shank at the position of preformed groove and be equipped with energy
The reinforcement anti-falling piece enough dismantled, the reinforcement anti-falling piece are cirque structure, the interior annular diameter for reinforcing anti-falling piece
With shank diameter be adapted, it is described reinforce anti-falling piece inner circle ring wall on and corresponding to preformed groove position at be equipped with and keep off
The adaptable card slot of the beveled end of block is made of elastic material at the position for reinforcing corresponding on anti-falling piece card slot.
As a kind of optimal technical scheme of the utility model, on the lateral wall for reinforcing anti-falling piece and correspond to card slot
Position at be equipped with arc button slot.
As a kind of optimal technical scheme of the utility model, described one end reinforced on anti-falling piece close to plunger is equipped with bullet
Property seal washer.
As a kind of optimal technical scheme of the utility model, the elastic component is made of several springs.
The utility model has the beneficial effects that：
1, the structure design of the utility model is reasonable, convenient to disassembly, and the block being provided with is inserted into straight pin ontology
It is skidded off outside preformed groove under the effect of the elastic force of elastic component after pin hole, to play the purpose that blocking straight pin ontology falls off, installation
It is very convenient, and when people need to dismantle straight pin ontology, it is only necessary to block is squeezed into preformed groove, outside
Need to be convenient to disassembly by external tool, and good anti-drop effect；
2, the reinforcement anti-falling piece of the utility model setting can further improve the anticreep effect of straight pin ontology, simultaneously
The elastic packing washer on reinforcing anti-falling piece, which is arranged, can also enhance the connection sealing of straight pin ontology.
