Referring to FIGS. 1 to 5 , the utility model device includes a reel body 8 , a reducer 9 , a hysteresis coupling 10 , a motor 1 and a base 4 . One side of the reel body 8 is insulated and connected to the electric brush 15 embedded in the end of the mains cable 7. The fixed end of the brush 15 is connected to the power connection line of the mobile system, and the cable 7 is wound on the reel according to the required length. The periphery of body 8. The hysteresis coupling 10 , the speed reducer 9 and the reel body 8 are sequentially connected coaxially and supported by two brackets 14 fixed on the base 4 . The hysteresis coupling 10 is driven by the motor 1 installed on the base 4 through a belt 13, and the input end of the hysteresis coupling 10 is provided with a hand wheel 12 for fine adjustment. Below the reel body 8 , between the two ends of each support 14 , a cable rack 3 composed of two horizontally arranged and vertically vertical circular tubes is arranged. One end of the output cable 7 of the base 4 is articulated to the overturning frame 2 through a plurality of hinges 21 , and a horizontal bracket 16 with a strip-shaped hole 22 is arranged on the overturning frame 2 . A forward crimping wheel 17, a guide wheel 19 and a reverse crimping wheel 18 that can slide along the strip hole 22 are arranged on the horizontal support 16, and the cable 7 passes through the cable rack 3, the guide wheel 19, and the forward crimping wheel 17 The upper wheel groove or the lower wheel groove and the upper wheel groove or the lower wheel groove of the reverse crimping wheel 18 are connected with the commercial power supply cabinet.
