Slot is fitting to connection by cover board and multi-directional ball.
Market routine techniques, oil cylinder can be used in the structure after adopting the above scheme, not being described in detail in the utility model
It can be around stabilizer blade axis rotation by connecting shaft part；Flip piece in full reduced time of piston rod, turn over by the connecting plate promotion on piston rod
Shaft realizes the flip-flop movement of oil cylinder；Sealing element is cylinder seal part, while piston rod is connect by multi-directional ball with universal spike,
Make universal spike that can be rotated freely in the multi-directional ball of certain angle range inner piston rod to adapt to ground with a slope.Thus protect
It has demonstrate,proved and provides reliable twelve Earthly Branches when oil cylinder also adapts to the ground handling in certain slope while can realize overturning for crane
Support acts on.
Description of the drawings
Fig. 1 is the overall structure diagram of the utility model.
Specific implementation mode
With reference to all attached drawings, the utility model is described in further detail, and the preferred embodiment of the utility model is：Ginseng
