A fixed spring is fixed at the through hole on the horizontal part of the U-shaped frame. The fixed spring is integrally sleeved outside the movable shaft, and the upper end of the fixed spring is fixedly connected to the bottom surface of the top limit plate. The cross-section of the top limit plate is semicircular. When the U-shaped frame moves and the top limit plate moves forward to the bottom of the trapezoidal block, the top limit plate is squeezed under the action of the inclined surface of the trapezoidal block, which squeezes the fixed spring and drives the movable shaft to move downward. The downward movement of the movable shaft brings the branch line plate downward. When the top limit plate moves to the horizontal part of the trapezoidal block, the lower convex thorn below the branch line plate contacts the inner bottom surface of the horizontal part of the contact box body.

[0009] The beneficial effects of the utility model are as follows: the heat dissipation effect of the contact box body is improved by the air supply fan, air supply channel, connecting pipe, arc-shaped box body and water-cooling part; when the front side knob is manually driven to drive the lead screw to rotate, the U-shaped frame moves forward to drive the branch line installation structure and the branch line plate to move forward; through the cooperation of the branch line installation structure and the trapezoidal block, during the forward movement of the U-shaped frame, the branch line plate moves downward to use the lower convex thorns to divide the wires to avoid entanglement; at the same time, during installation, the branch line plate is at a certain height and does not affect the installation of the wire body, and the practicability is strong.
