[0028] The drive mechanism 5 includes a driven gear 501 fixedly connected to the upper end of the rotating shaft 4. A driving gear 502 is meshed with one side of the driven gear 501. The driving gear 502 is connected to the output shaft of a reduction motor 503 mounted on the upper surface of the base tube 1. A removable lithium battery 504 is located on one side of the reduction motor 503 and mounted on the upper surface of the base tube 1.

[0029] The winding adjustment mechanism 6 includes a fixed cylinder 602 connected to the upper end of the driven gear 501 through a connecting shaft 601, and a plurality of connecting pieces 603 are slidably connected to the side wall of the fixed cylinder 602. The outer ends of the connecting pieces 603 located on the same vertical line are connected to an arc-shaped plate 604. The end of the connecting piece 603 located in the fixed cylinder 602 is in sliding contact with a reducing rod 605. The reducing rod 605 is fixedly sleeved on the guide rod 606. The lower end of the guide rod 606 is slidably inserted into a fixed tube 607 connected to the bottom surface of the fixed cylinder 602. Then, a spring 608 is sleeved on the guide rod 606, the upper end of the spring 608 is connected to a reducing rod 605 located at the bottom, and the lower end of the spring 608 is connected to the fixed tube 607. The upper end of the guide rod 606 is fixedly connected to a knob 609, and a stopper 610 is provided below the knob 609 and on the side wall of the guide rod 606. The stopper 610 can be engaged with an L-shaped plate 611 fixedly connected to the upper end of the fixed cylinder 602, and a retaining ring 612 is located below the arc plate 604 and connected to the connecting shaft 601.

[0030] A through slot 6021 is defined on the side wall of the fixing tube 602 for the connecting piece 603 to slide freely.

[0031] A limiting protrusion 6031 is provided on the edge of the lower surface of the inner end of the connecting piece 603 .

[0032] It should be noted that by providing the limiting protrusion 6031 , the connection piece 603 can be separated from the through groove 6021 .

[0033] The reducing rod 605 includes a frustum 6051 and a cylinder 6052 , and the bottom end of the frustum 6051 is fixedly connected to one end of the cylinder 6052 .

[0034] A protective shell 7 mounted on the base tube 1 is provided on the outer side of the driving mechanism 5 .

[0035] A rubber pad is provided on the lower surface of the telescopic tube 2 near the outer end.

[0036] Working principle: When in use, first pull the telescopic tube 2 out of the base tube 1 to increase the supporting stability of the cable retractor, then press the knob 609 to move downward, and rotate the knob 609 so that the stopper 610 on the side wall of the guide rod 606 is engaged with the lower side of the L-shaped plate 611. At this time, the side surfaces of the frustum 6051 of the two reducing rods 605 sleeved on the guide rod 606 will squeeze the inner end of the connecting piece 603, so that the connecting piece 603 slides outward in the through groove 6021, and then one end of the wire to be retracted is wrapped around the outer side of the arc plate 604, and then the reduction motor 503 is started by the control switch to drive the driving gear 502 to rotate. The rotating driving gear 502 will drive the driven gear 501 meshing with it to rotate, and the rotating driven gear 501 drives the fixed cylinder 602 to rotate through the connecting shaft 601, and the rotating fixed cylinder 602 will drive the arc plate 604 to rotate through the connecting piece 603. The guide rod 606 is supported by the spring 608 and does not move downward, so that the wound wire can be easily removed from the curved plate 604.

[0037] When it is necessary to release the wires, the following operations can be performed on the wires that have not been removed from the curved plate 604:

[0038] Start the reduction motor 503 to reverse, and the operator pulls one end of the wire to the position where it needs to be connected to the power supply. While the operator pulls the wire, the arc plate 604 will rotate with the reduction motor 503, and the wire laying can be completed smoothly without causing the wires to accumulate on the ground and cause knots and other problems.

[0039] When it is necessary to pay out the wire reel that has been taken off the curved plate 604 after winding, the following operations can be performed:

[0040] The wire reel is placed on the outside of the curved plate 604, and the knob 609 is pressed so that the side of the cone body 6051 of the reducing rod 605 squeezes the inner end of the connecting piece 603, so that the curved plate 604 moves away from the fixed tube 602 to tighten the wire reel. Then the reduction motor 503 is started to reverse, which allows the operator to pull the end of the wire to complete the wire unwinding.

[0041] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Any ordinary technician in this industry can smoothly implement the present invention as shown in the drawings and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with this profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention.
