Further, described sleeve pipe one end is provided with the first abutting part for abutting spring one end, and the cutting ferrule is provided with abutting
Second abutting part of the spring other end.
By above-mentioned technical proposal, spring one end in compressive state abuts the first abutting part of sleeve pipe, and the other end is abutted
Second abutting part of cutting ferrule, the elastic force of spring becomes to making to be fastened on sleeve pipe towards the direction movement away from the first abutting part, makes cutting ferrule
Clamp sleeve.
Further, the plug is provided with the first block for preventing sleeve from skidding off plug, and the sleeve is provided with and institute
State the second block that the first block is abutted against.
By above-mentioned technical proposal, the second block and first block of sleeve are abutted against, so that sleeve will not be from plug
It is upper to be skidded off with sleeve pipe connection one end.
Further, the connecting cavity is inserted in sleeve pipe, integrally formed with sleeve pipe.
By above-mentioned technical proposal, connecting cavity is inserted in sleeve pipe, and the joint of conveying liquid is formed after being connected with plug.
In sum, the utility model has the advantages that：The utility model will be threadedly connected to by locking member
Sleeve on sleeve pipe is compressed and prevents sleeve from rotating, and after the fuselage long-term jitter of snap joint connection, is still ensured that and is quickly connect
The connection of head is in more close state.
