The utility model discloses a following technical scheme realizes: the clamp spring and cylindrical pin thrust structure comprises a bolt, a groove-shaped nut, a cylindrical pin and a steel wire clamp spring, wherein the groove-shaped nut is sleeved on the bolt, the cylindrical pin penetrates through a pin hole reserved in the groove-shaped nut and a pin hole reserved in the bolt, and the steel wire clamp spring is sleeved on the groove-shaped nut and used for limiting the cylindrical pin.

Further for realizing better the utility model discloses, adopt the following structure that sets up very much: and an installation groove for installing the steel wire clamp spring is formed in the periphery of the groove-shaped nut.

Compared with the prior art, the utility model, following advantage and beneficial effect have:

the utility model provides a split pin wearing and tearing cell type nut's problem prevents that the split pin fracture from causing spare part to drop and wearing and tearing nut to produce metal residue under operating condition, replaces the split pin into the cylindric lock to supplementary steel wire jump ring carries on spacingly, can be spacing in the round pin hole with the cylindric lock, even if rock, also can not cause wearing and tearing cell type nut, and the condition emergence that the cylindric lock fracture, drop can not appear yet.

The utility model discloses replace the split pin by the cylindric lock, fix the cell type nut and prevent that it from not hard up the coming off because of fluidic continuous erodeing and piston motion. The cylindric lock is spacing to be fixed in the bolt hole by the steel wire jump ring, prevents that it from taking place the displacement and dropping.

The utility model discloses prevent that the cell type nut from leading to droing because of fluid erodees, piston action, avoiding the cylindric lock wearing and tearing cell type nut.
