The two supporting blocks are arranged opposite to each other, and the upper parts of the opposite sides of the two supporting blocks are provided with supporting surfaces for supporting the cable reels, and the distance between the two supporting surfaces increases from bottom to top. The opposite side of the support block is fixed with a second sliding rod that penetrates and extends to the outside of the support base, and the support base is provided with two transverse sliding holes that communicate with the corresponding sliding grooves and allow the corresponding second sliding rods to slide laterally. , a longitudinally arranged longitudinal sliding slot is provided at the position corresponding to the middle of the two lateral sliding holes on the support base, and a first sliding rod is slidably connected in the longitudinal sliding slot, and the outer side of the first sliding rod is slidably connected. The end extends to the outside of the support base, a connecting rod is respectively connected between the first sliding rod and the two second sliding rods, and the two ends of the connecting rod are hinged with the first sliding rod and the second sliding rod respectively.

Further, the accommodating groove is provided with a driven shaft parallel to the width direction of the support base and located below the support plate, the driven shaft is fixedly sleeved with a driving wheel, and the two driven shafts of the support base are The opposite ends of the shaft extend through and between the two support bases and are respectively connected to the output ends on both sides of a double-shaft motor. The bottom of the double-shaft motor is connected with a fixed seat, and the driven shafts on both sides of the driving wheel are partially connected. They are all rotatably connected with the support base through the first bearing. When the cable reel is located in the accommodating slot, the bottom of the cable reel is attached to the driving wheel, and the driven shaft can be driven to rotate by driving the dual-axis motor, thereby driving the driving wheel to rotate, which in turn can drive the cable reel to rotate. Electric drive for the pay-off operation of the reel.

Further, the free ends of the two output shafts of the dual-shaft motor are coaxially fixed with a driving sleeve for inserting the outer end of the driven shaft on the phase side, and the inner ring side of the driving sleeve is on the inner ring side. An inner gear ring is provided, and an outer gear ring matched with the inner gear ring is arranged on the part of the driven shaft located on the outer side of the support base. By adjusting the depth at which the driven shaft is inserted into the driving sleeve, the distance between the two supporting bases can be adjusted, thereby being able to adapt to cable reels of different lengths.

Further, the cross section of the longitudinal sliding slot is in a "T" shape, and the corresponding end of the first sliding rod is in a "T" shape matching the longitudinal sliding slot.
