The invention discloses a novel single-hand pressing plug-in type socket. The socket comprises a socket body and a power connection device located in the socket body. The power connection device comprises a connection cavity with an upward opening; a lifting cavity is formed in the lower side of the connection cavity; a lifting plate is connected into the lifting cavity in a sliding manner; a first spring is fixedly connected between the lifting plate and the lower end wall of the lifting cavity; a lifting shell is arranged in the connection cavity; and a first fixed rod which is in sliding connection with the socket is fixedly connected between the lifting shell and the lifting plate. The socket is simple in structure, convenient to operate, capable of achieving installation and separation of the plug on the socket with one hand and convenient for people to operate an electric appliance with one hand, meanwhile, the socket is provided with the power-off protection device, when no plugexists on the socket, the socket can be automatically powered off, when at least one plug exists on the socket, the socket is powered on, and safety accidents caused when people forget to power off the socket are avoided.

The embodiment of the invention provides a driving shaft, which comprises a driving shaft body, a first driving shaft, a second driving shaft and a driving shaft, the spring bolt is accommodated in the first groove; the spring is contained in the first groove, and the two ends of the spring are connected with the driving shaft body and the spring bolt correspondingly; the spring bolt partially extends out of the first groove under the action of the spring and locks the rotor on the driving shaft body in the axial direction; the driving shaft body further comprises a first through hole, the spring bolt further comprises a second through hole, projections of the first through hole and the second through hole in the axial direction of the driving shaft body at least partially coincide, external force acts on the spring bolt through the first through hole and the second through hole, the spring bolt compresses the spring under the action of the external force and retracts to the first groove, and the rotor is unlocked from the driving shaft body. According to the embodiment of the invention, the operation is simple, convenient and effective, the reliability is high, the operation burden of experimenters is reduced, and the situation of safety accidents caused by improper locking is avoided.

The invention relates to an electric vehicle charging gun, comprising a gun body provided with an inner cavity, a plug, a locking member and a wire harness, wherein a clamping sleeve is inserted on the gun body in a sliding manner; the clamping sleeve and the gun body are fixedly connected in a sliding manner through at least one ball plunger; the wire harness is fixedly connected with the clamping sleeve, and one end of the wire harness is placed in the inner cavity and connected with the plug; the locking member is laterally rotatably mounted on the gun body; the gun body is provided with afirst spring, and the locking member rotates counterclockwise under the elastic force of the first spring; the gun body is provided with a sliding rod that slides up and down, the upper end of the sliding rod is provided with a connecting rod, the lower end of the connecting rod is hinged with the upper end of the sliding rod, the upper end of the connecting rod is provided with a straight groove,the right end of the locking member is provided with a hinge shaft, and the hinge shaft is arranged in the straight groove; a second spring is arranged on the gun body, and the sliding rod slides upward through the elastic force of the second spring; and the sliding rod is connected with the clamping sleeve. The electric vehicle charging gun in the invention can satisfy normal use when charging the vehicle and also can ensure that the charging gun is pulled off safely from the vehicle in case of emergency.

The invention relates to a charging gun allowing forced power off. The charging gun comprises a gun body with an inner cavity, a plug, a lock piece, a wire harness, and a cable, wherein a plug sleeveis inserted in the gun body in a sliding manner, the plug sleeve and the gun body are in slide positioning connection through at least one ball plunger, an insert end of the plug sleeve has a plug hole, the gun body has the plug matched with the plug hole, the plug is inserted in the plug hole, the wire harness is in the inner cavity, one end of the wire harness is connected with the plug, the other end of the wire harness is connected with the plug, one end of the cable is connected with the plug hole, the plug and the gun body are connected in a rotating manner, a torsion spring is sheathedat the right of the plug, and two ends of the torsion spring are respectively connected with the gun body and the plug. The charging gun can be used normally when a vehicle is charged, and in emergency, it is ensured that the charging gun cuts off the power when being pulled and releases the vehicle safely.
