The invention relates to a winding device, in particular to an adjustable electric power cable winding device. The adjustable electric power cable winding device is more compact and uniform in windingand capable of being detached to be maintained or stored. The adjustable electric power cable winding device comprises a top plate and the like, the bottom of the right side of the top plate is connected with a motor, and the bottom of the motor is connected with a first rotating rod; the bottom of the first rotating rod is connected with a winding drum, the middle of the left wall of the windingdrum is connected with a clamping rod, and a clamping hole is formed in the clamping rod; and a fixing mechanism is connected in the winding drum, and a lifting mechanism is connected to the outer side of the lower part of the winding drum. According to the adjustable electric power cable winding device, first wedge-shaped blocks and second wedge-shaped blocks are arranged, so that gear rods canblock electric power cables when the electric power cables are wound, and the effects of being much cleaner and more comprehensive in cleaning and convenient to move are achieved.
