Double-lifting-ring shock absorber piston rod structure with clamping groove

The utility model relates to the technical field of shock absorbers, in particular to a double-ring shock absorber piston rod structure with a clamping groove, which comprises a piston rod and an oilseal protective sleeve mounted at the front end of the piston rod, a stepped table is arranged at the front end of the piston rod, and the oil seal protective sleeve is completely attached to the front end of the piston rod and completely covers the stepped groove. By means of the structural improvement of the clamping groove piston rod of the double-lifting-ring shock absorber, the problem of later-period oil leakage caused by the fact that an oil seal lip is scratched by an assembled piston rod assembly due to the fact that the surface quality of the clamping groove of the piston rod is different is fundamentally solved. The quality of the piston rod assembly in the assembling process is improved, the manufacturing cost of the piston rod is saved, and greater competitive advantages are provided for the quality a
