[0003] A Chinese patent discloses a lateral spring-type terminal (authorization announcement number CN204088588U). This patented technology fixes and connects the wiring through a spring-type structure, and an anti-slip ring is arranged above the eleven-character screw, so that no matter how the eleven-character screw is turned, the screw will not fall out, thereby increasing the fixing ability of the terminal; however, it has certain disadvantages: the terminal is easily affected by external vibrations during use, such as the automatic opening and closing of the contactor, the operation of the motor, etc. These vibrations are transmitted to the eleven-character screw. Over time, the eleven-character screw will rotate, resulting in loose fixation. Utility Model Content

The adjusting bolt 3 can be turned clockwise to make it descend and drive the spring piece 5 to press the wire. The adjusting bolt 3 is turned counterclockwise, and the spring piece 5 is reset upward by its own elastic force.
