[0032] Working principle: When in use, the staff will insert the two power cords that need to be connected into the two sets of wire sockets 8 respectively, and drive the first connecting rod 4 to rotate along the hinge connection point on the support plate 3 through the handle 6 by pulling the control handle 6 up and down, and drive the second connecting rod 5 at one end to move upward through the rotation of the first connecting rod 4, and drive the pressing block 7 to move upward from the circuit wiring compartment 2 through the second connecting rod 5, and put the power cord between the pressing block 7 and the circuit connection board 9, and press the handle 6 downward to drive the pressing block 7 to descend and press the two power cords tightly on the circuit connection board 9 Then, by pushing the push rod 20, the push rod 20 slides in the circuit control compartment 10, driving the pressure rod 18 to move, and moving one end of the pressure rod 18 from the second control rod 15 through the third connecting rod 14 to the top of the first control rod 12. By squeezing the pressure rod 18, the two ends of the first control rod 12 are pressed on the two sets of circuit connection plates 9 at the bottom of the first slide groove 11. At the same time, due to the movement of the slider 16, the inclined surface of the wedge block 19 is squeezed to compress the third spring 22.

At this time, the pressure rod 18 follows the slider 16 to move out from above the first control rod 12 and slide to above the second control rod 15. Since the second control rod 15 is larger than the first control rod 15, the pressure rod 18 can be adjusted to the position of the second control rod 15.
