Plug cylinder is fixedly connected with the casing by front end housing, and rack end is connected with piston rod end, and hydraulic channel is formed with back cylinder cover；It is main
If hydraulic cylinder mechanism uses symmetrical double-piston mechanism, piston rod of the rack both ends respectively with left and right piston mechanism is consolidated
Fixed connection；Back cylinder cover is provided with buffer unit, and the buffer unit is made up of the mozzle on back cylinder cover, the mozzle one
End is fixedly mounted on back cylinder cover inwall center, and its endoporus connects with hydraulic channel, and the mozzle other end extend into piston cylinder
In rodless cavity, piston rodless cavity side end face center is formed with the metering hole coordinated with mozzle periphery gap；In housing and tooth
Bar sets friction adjustment mechanism between the back side.
In above technical scheme, friction adjustment mechanism is by adjusting screw rod, stressed on friction block composition, adjusting screw rod screw thread peace
On housing, stressed on friction block upper surface contacts with adjusting screw rod lower surface, and stressed on friction block lower surface is fitted in the rack back of the body
Face.
