When the inner side surface of the pressing block contacts the surface of the conical sleeve, the conical sleeve applies an outward force to the pressing block, so that each pressing block moves outward at the same time; the pushing mechanism continues to move downward, and the inner side surface of the pressing block moves downward along the surface of the conical sleeve and pushes the retaining spring to move downward. After the retaining spring is separated from the conical sleeve, it is automatically clamped into the clamping groove of the dust cap, and the installation of the retaining spring is completed; the driving mechanism drives the pushing mechanism to move upward and reset.

[0005] As an improvement, the pressing block is fan-shaped, and the lower end of the swing arm is connected to the outer wall of the pressing block by bolts.

[0006] As an improvement, the pushing mechanism is sleeved with a spring ring for bringing the pressing blocks closer to each other.

[0007] As an improvement, a telescopic rod is provided in the middle of the bottom of the fixed seat, a positioning block is provided at the lower end of the telescopic rod, a return spring is sleeved on the telescopic rod, the lower end of the return spring abuts against the positioning block, and the upper end of the return spring abuts against the fixed seat.

[0008] As an improvement, control buttons are provided on both sides of the mounting base.

[0009] As an improvement, the driving mechanism includes a support frame and a cylinder inverted on the support frame, and the telescopic rod of the cylinder acts on the fixed seat.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] The tapered sleeve and the pushing mechanism cooperate with each other to clamp the retaining spring into the retaining groove of the dust cap in a directional manner, thereby simplifying the difficulty of the retaining spring assembly operation and improving the assembly efficiency.
