Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
As depicted in figs. 1 and 2, it is in tube-in-tube structure shape open at one end that the return spring seat 1 of the utility model is whole,
The end cooperated with master cylinder piston 8 is externally provided with guiding surface 2 and ladder face structure 3.Guiding surface 2 is arranged in return spring seat 1
Between the end face and outer peripheral surface of end, it is oriented to for return spring seat 1 to be pressed into master cylinder piston 8；Ladder face structure 3 is set
It sets between the outer peripheral surface at 1 middle part of outer peripheral surface and return spring seat of 1 end of return spring seat.
As shown in Fig. 2, the return spring seat 1 of the utility model is designed as the conical surface in the end cooperated with master cylinder piston 8
4, the inner peripheral surface of 1 end of return spring seat is arranged in the conical surface 4, and inwardly, big end is outwardly for 4 small end of the conical surface.The conical surface 4 is spring
When seat is assembled to inside master cylinder piston, inside shrink space effect is provided, prevents from interfering with the return spring of inside press fitting.
As shown in Fig. 2, the return spring seat 1 of the utility model has open slot in the end design cooperated with master cylinder piston 8
Structure 5, end design have opening slot structure 5, inside contraction distortion when spring base being facilitated to assemble.
As shown in Figure 1, the middle part of return spring seat 1, which is equipped with, extends transversely through hole 6, for piston assembly in compression work,
