Part, the flexible stroke and flexible hop count that can freely control hydraulic cylinder, to meet more demands.
To achieve the above object, the technical solution adopted in the utility model is：It includes mounting seat, locking nut, connection
Pipe, seal washer, outer steel sleeve pipe, seal assembly one, piston bush, seal assembly two, piston rod, spacing ring, T-shaped screw rod, regulation
Control piece；The upper end of described mounting seat is tilted and is plugged with connecting tube, and the outer layer of connecting tube is fixed by locking nut；
The right-hand member of mounting seat is fixed with close by seal assembly one on the inside of outer steel sleeve pipe, the right-hand member of outer steel sleeve pipe by seal washer sealing
Envelope is plugged with piston bush；The inside of described piston bush is plugged with piston rod by seal assembly two, and the top of piston rod is fixed
T-shaped screw rod is connected with restraining position ring block, spacing ring；Wherein, regulation control piece is plugged with the outside of outer steel sleeve pipe, control piece is adjusted
Inner side be connected with piston bush surface.
Preferably, described regulation control piece can be replaced control battery valve, automatic control structure is realized.
Preferably, described seal assembly one is made up of y-type seal ring, support ring, seal washer.
After said structure, the utility model has the beneficial effect that：A kind of new automobile described in the utility model is used
Multistage hydraulic cylinder, it uses the piston bush of multi-stage expansion and locks control piece, can freely control the flexible of hydraulic cylinder
Stroke and flexible hop count, to meet more demands, the utility model has simple in construction, sets reasonable, cost of manufacture
Low advantage.
