When the wire winding and unwinding device is moved, the pull rod 41 can be directly pulled to drive the moving wheel 11 to move on the ground. Or directly pushed to the upper part of the wire winding and unwinding device to drive the moving wheel 11 to move on the ground. Or the pulling rod 41 is pulled to be matched with the upper part of the wire winding and unwinding device, so that the moving wheel 11 is driven to move on the ground.

When the wire winding and unwinding device moves in place and needs to be fixed, the extension rod 15 is held by both hands, the rear end of the support 1 is lifted, the limit support rod 51 is rotated to be unfolded, and the limit support fixing piece 52 penetrates through the third limit hole 55 from top to bottom and is embedded into the first limit hole 53 to be unfolded and fixed, so that the limit support rod 51 is prevented from rotating. After the limiting support rod 51 is unfolded and fixed, the extension rod 15 is put down, the limiting support rod 51 is propped against the ground, and the movable wheel 11 on the support 1 is limited to move involuntarily, so that the wire winding and unwinding work is influenced.

When collecting the electric wires, the rotary handle 66 can be rotated, the rotary handle 66 drives the spool shaft 63 to rotate, and the spool shaft 63 drives the movable sleeve 66 to rotate on the fixed shaft 25 so as to perform the electric wire collecting work. When the wire is discharged, the wire is pulled to rotate the spool 63.
