Radial direction through hole on the described circular nut is three, and differs 60 ° at interval.
Leave oil cabinet between the double-screw bolt top of the inner roof wall of described circular nut and base, the roof of circular nut has axial oil hole, and axially oil hole is communicated with the inner chamber of oil cabinet and spring case.
On the head of described caging bolt and adjusting bolt nut is housed all.
The connecting portion of described base has two connecting bores.
The top of described spring case has wearing layer.
After adopting said structure, when needs are adjusted the vertical angle of coupler draft gear single-piece, only need the adjusting bolt is unloaded, and angle circular nut is left-handed or that dextrorotation is certain, after reaching requirement, the slow whole angle of hook reinstalls and the fastening adjustment bolt gets final product, and easy to adjust, simple to operate, time saving and energy saving.It is few that the utility model also has a part, integrated level height, the characteristics of convenient disassembly.
