[0006] The first fixing seat is symmetrically provided with two connecting rods; the second fixing seat is symmetrically provided with two connecting holes for matching with the connecting rods;

[0007] Furthermore, semicircular guide rings are arranged on the side walls of the first fixing seat and the second fixing seat at the positions of the semicircular arc grooves.

[0008] Preferably, the semicircular guide ring is a chamfered structure.

[0009] Preferably, the angle between the semicircular guide ring and the horizontal plane is 120°.

[0010] Preferably, each of the connecting rods is also provided with an external thread.

[0011] Preferably, the connecting rod is inserted into the connecting hole of the second fixing seat and is threadedly connected and locked with the external thread of the connecting rod through a locking nut.

[0012] Preferably, the first fixing seat and the second fixing seat are both rectangular structures.

[0013] The beneficial effects of the utility model are:

[0014] 1. The utility model has a simple structure and strong practicality. The utility model can assist the rapid installation of the wire retaining ring, thereby improving the assembly efficiency of the retaining ring. Moreover, the first fixing seat and the second fixing seat of the utility model are locked by nuts, thereby facilitating rapid disassembly and assembly;

[0015] 2. The utility model uses a guide ring with a chamfered structure to guide the installation of the wire retaining ring. In addition, the utility model adjusts the diameter of the through hole between the first fixing seat and the second fixing seat by adjusting the locking nut, thereby meeting the installation of the wire retaining ring of the valve sleeve with different diameter sizes.
