The elastic sheet 130 is disposed in the mounting groove 1111 and surrounds the rotating body 112, and one end of the elastic sheet 130 extends to a direction close to the wire insertion hole 1112 to form a deformation portion 131. One end of the button 140 is inserted into the mounting groove 1111 to move relative to the direction of the transformation portion 131, so that the transformation portion 131 performs a rotational motion around the rotating body 112. When the wire is required to be connected, in the process of inserting the wire 20 into the mounting groove 1111 through the wire insertion hole 1112, the deformation portion 131 of the elastic piece 130 is deformed by the downward pushing force of the wire 20 and rotates around the rotating body 112, and when the insertion of the wire 20 is stopped, the deformation portion 131 rebounds to clamp the wire 20 and the contact bridge 120.
