[0014] The present invention provides a device for laying power cables. It has the following beneficial effects: (1) In this invention, the first transmission shaft is driven to rotate by a motor. When the first transmission shaft rotates, the transmission shaft will drive the first long plate and the bucket to rotate. When the bucket rotates, it can dig open the soil and create a small ditch for laying the cable. When the first long plate rotates, the first long plate will drive the semi-cylindrical barrel to rotate.

[0016] (3) The invention drives the transmission shaft 2 to rotate through the belt 1. When the transmission shaft 2 rotates, the transmission shaft 2 drives the limit roller 3 to rotate. When the limit roller 3 rotates, the belt 2 is driven to rotate. When the belt 2 rotates, the cable is transported downward. The lateral position of the belt can be changed by adjusting the bolt, so that cables of different sizes can be transported. When the slider 2 moves to the right, the slider 2 drives the belt 2 to move to the right. When the belt 2 moves to the right, the right side of the cable will contact the inclined block. The inclined block will be pushed to the right by the cable. At this time, the push block will contact the switch. The switch will extend the electric telescopic rod 2. When the electric telescopic rod 2 is extended, the push block will contact the bolt, which will prevent the bolt from continuing to rotate and cause damage to the cable.
