The cable is fixed at the line inlet position through the coordinated action of the upper fixing mechanism and the lower fixing mechanism. When the cable is pulled by external force, the cable passed through the squeezing channel has a certain degree of elasticity, which can not only avoid being directly tripped by the cable, but also offset a part of the external force under the action of the elastic squeezing block, so that the force applied to the upper fixing mechanism is reduced, thereby ensuring the clamping force of the upper fixing mechanism. Therefore, the cable will not be easily pulled off the power supply box, thereby reducing the danger and ensuring the stable operation of the ship's power equipment.
