Novel electric switch machine plug-in connector

The utility model discloses a novel electric switch machine plug-in connector which comprises a plug, the right side of the plug is in butt joint with a socket, the inner wall of a torsion spring is in clearance fit with the outer wall of a connecting shaft, one end of the torsion spring is fixedly connected to the outer wall of a curved bar, and the other end of the torsion spring is fixedly connected to the outer wall of the socket. A through hole is machined in the left side of the top of the curved bar, and the left side of the curved bar is rotationally connected with the through hole through a connecting shaft. According to the novel electric switch machine plug-in connector, a curved bar drives a pulley to move into the inner wall of the shell, and after the pulley moves into the shell, the curved bar is driven to rotate anticlockwise through contact with an inclined surface of a clamping block, so that the curved bar is in contact with the clamping block, and rapid separation of a plug and a socket is
