[0028] A first spring 106 is disposed in the switching slot 108 , and the first spring 106 is connected to the regulating contact piece 112 . The elastic force of the first spring 106 can enable the regulating contact piece 112 to quickly reset and move, thereby facilitating automatic control of the on and off of the connection.

[0029] The adjusting rod 102 is movably arranged in the adjusting mouth, and an insulating pull handle 101 is also arranged on the adjusting rod 102 to ensure the safety of the adjusting rod 102 when being pulled. The adjusting mouth is arranged on one side of the insulating sleeve 3, which can guide the movement of the adjusting rod 102. The second spring 103 is sleeved on the adjusting rod 102, one end of the second spring 103 is connected to the adjusting rod 102, and the other end of the second spring 103 is connected to the adjusting mouth. The elastic force of the second spring 103 can drive the longitudinal wedge block 104 to reset and move.

[0030] First, insert the phase line 5 (live wire or neutral wire) into the insulating sleeve 3. When the phase line 5 is in contact with the adjusting contact 112, the phase line 5 drives the adjusting contact 112 to move, and the adjusting contact 112 drives the positioning wedge 105 to move, and the adjusting contact 112 compresses the first spring 106. The movement of the positioning wedge 105 drives the longitudinal wedge 104 to move upward, and the movement of the longitudinal wedge 104 drives the adjusting rod 102 to move, and the adjusting rod 102 compresses the second spring 103. When the adjusting contact 112 is in contact with the main conductive plate 107, the second spring 103 drives the adjusting rod 102 to reset, and the adjusting rod 102 drives the longitudinal wedge 104 to reset, and the longitudinal wedge 104 clamps the positioning wedge 105.
