The right side face of the limiting cover and the right side wall of the inner cavity are of arc-shaped columnar structures, so that the limiting cover is matched with the arc-shaped end of the outer circle of the male head of the U-shaped pin in a protruding mode, and when the limiting cover is held to force, no edges and corners are left, and the limiting cover is more comfortable.
The rear perforation and the front perforation are used for penetrating a string or an iron wire, so that more of the utility model are connected in series, and the storage and the use are convenient.
The arrangement of the expansion joint enables the two clamping jaws to have better elasticity, and labor is saved during installation.
The central angle of the opening at the left side of the positioning hole is 60-75 degrees, preferably 75 degrees, so that the U-shaped pin is ensured to be limited, and meanwhile, the installation and the disassembly are more labor-saving. The disassembling can be realized by adopting 2 pliers to clamp one claw respectively and pulling the two claws forcefully in opposite directions, and the distance between the two claws is increased, so that the utility model can be disassembled.
In conclusion, the quick-plug type connector is novel in design, simple in structure and convenient to install, the male head and the female head of the quick-plug type connector are connected, the U-shaped pin and the male head are connected, and the U-shaped pin and the female head are connected in a mutually-related manner, so that the pin removal of the U-shaped pin is avoided, and the safety and the reliability of the connection position of the hydraulic pipeline are greatly improved.
