The utility model is further described with reference to the following detailed description and accompanying drawings.

Referring to fig. 1 to 4, a portable cable reel retracting device includes a claw wheel 3 and two sets of brackets, the two sets of brackets are respectively disposed at two ends of a cable reel 8, and each set of brackets includes two movable brackets 1, the two movable brackets 1 clamp a baffle 81 of the cable reel 8 from two sides, so that the baffle is kept stable in the rotating process, and meanwhile, the two movable brackets 1 of each set of brackets are connected through a screw 5, and the distance between the two movable brackets 1 is controlled through the screw 5, so that the cable reel 8 is controlled to lift and separate from the ground;

the claw wheel 3 is preferably made of metal, triangular teeth are arranged on the periphery of the claw wheel 3, and the claw wheel 3 is connected with a retraction motor 4 and is fixed on one of the movable brackets 1 through an upright post 2; when in use, the claw wheel 3 is abutted against the baffle plate 81 of the cable reel 8, and the baffle plate 81 is made of wood, so that the claw wheel 3 can grasp the baffle plate 81 and drive the baffle plate to rotate when rotating, thereby realizing the winding and unwinding of the cable.

It should be noted that, in order to make the cable drum 8 rotate under the action of the claw wheel 3, the claw wheel 3 needs to be offset from the axis of the cable drum 8, and preferably, the claw wheel 3 is located at the lower half part of the cable drum 8, so as to avoid the column 2 from being too long and unstable.

As shown in fig. 2, the moving bracket 1 includes a base 11, two rollers 12, and two rollers 13, wherein the rollers 12 and the rollers 13 are respectively disposed on the top and the bottom of the base 11, the rollers 13 are universal wheels and have brakes to facilitate the moving of the moving bracket 1, the two rollers 12 are inclined to each other, so that the baffle 81 of the cable drum 8 is used to fall between the two rollers 12 during the rotation process;

as shown in fig. 3, a lifting motor 6 is arranged on one movable bracket 1 in each group of brackets, the lifting motor 6 drives a screw 5 to rotate through a gear 7, specifically, one end of the screw 5 is rotatably connected with one movable bracket 1 and is connected with the lifting motor 6 through the gear 7, and the other end of the screw 5 is connected with the other movable bracket 1 through a thread; as shown in fig. 3 and 4, when the lifting motor 6 is started, the screw 5 rotates to change the distance between the two mobile brackets 1, and when the distance decreases, the cable drum 8 is circular, so that the two mobile brackets 1 lift the cable drum 8 to seat on the roller 12, thereby freely rotating;

because the cable drum 8 is not an object with uniform quality, the cable drum can rock when rotating, in order to reduce the rocking, the rolling shaft 12 is fixed on the sliding rod 14, the sliding rod 14 is movably arranged on the base 11 in a penetrating way, and a spring 15 is arranged between the bottom of the sliding rod 14 and the base 11, so that a certain buffer is arranged between the cable drum 8 and the base 11.

Preferably, the retraction motor 4 and the lifting motor 6 are respectively arranged on different mobile brackets 1, so that the accumulation of parts on a single mobile bracket 1 is avoided.

It is worth mentioning that each group of brackets is provided with a claw wheel 3 and a retracting motor 4 which can apply force from two sides of the cable reel 8 simultaneously, so that the cable reel 8 can rotate more flexibly; preferably, the two claw wheels 3 may be diagonally distributed at both ends of the cable drum 8.

The principle of the utility model is as follows: as shown in fig. 3, the mobile brackets 1 are placed at the two ends of the cable drum 8 from the outside, then the lifting motor 6 is started, the screw 5 is rotated to reduce the distance between the two mobile brackets 1 (in the process, the position of the mobile bracket needs to be manually adjusted to enable the baffle 81 to be positioned between the two rollers 12), and at the moment, the two mobile brackets 1 lift the cable drum 8 to be seated on the rollers 12; then, the retracting motor 4 is started, the claw wheel 3 rotates, the cable reel 8 is driven to rotate, and the retracting of the cable is achieved.
