The pinion 15 is connected to the output end of the screw motor 14, and the large gear 13 is meshed with the pinion 15.

[0031] In this embodiment, because the screw motor 14 is externally connected to a power supply and a switch, when the screw motor 14 is started, it will drive the pinion 15 to rotate. As the pinion 15 is meshed with the large gear 13, the large gear 13 drives the reciprocating screw 16 to rotate. The pinion 15 and the large gear 13 cooperate to form a reduction structure, which can drive the reciprocating screw 16 to rotate.

[0032] Working principle: when the slide 8 is installed under the drum 3, the wire rope needs to be located in the rope mouth 17 of the slide plate 9, and the electromagnet is inserted into the slot of the socket 4. By pressing the power switch button 7, the copper wire 21 can be energized, and the electromagnet attracts the socket 4, so that the vertical plate 6 can be installed on the right part of the side plate 2 on the right side, and the installation of the slide 8 is completed. Then, when the drum 3 rotates to rewind the wire rope, the screw motor 14 can be started. At this time, the screw motor 14 drives the small gear 15 to rotate. As the small gear 15 is meshed with the large gear 13, the large gear 13 drives the reciprocating screw 16 to rotate. The reciprocating screw 16 is threadedly matched with the slider 11 on the front side, so that the slider 11 on the front side reciprocates left and right inside the slide groove 10 on the front side, and the slider 11 on the front side will drive the slide plate 9 to reciprocate left and right, so that the slide plate 9 can drive the wire rope to reciprocate left and right, so that the wire rope can be reeled more neatly on the outer wall of the drum 3.
