As a preferred embodiment, the device further comprises a disc circle 31 arranged on the columnar rotating shaft 3, four clamping devices 5 are uniformly arranged on the disc circle 31, each clamping device 5 comprises a U-shaped clamping groove 51 arranged along the radius direction of the disc circle 31, and a threaded rod 52 with a handle vertically penetrating through the side wall of the clamping groove 51 is arranged on each clamping groove 51; the cable reel and the cylindrical spindle 3 are connected as a whole by aligning the spokes of the cable reel with the clamping grooves 51 of said clamps 5 and tightening it by means of the threaded bar 52 with a handle.

As a preferred embodiment, the device further comprises a driven sprocket 32 arranged on the columnar rotating shaft 3 and a horizontal motor 33 arranged on one side of the driven sprocket 32 and positioned on the lower surface of the box body 21 on the L-shaped supporting rod 1, wherein a driving sprocket 34 is arranged on an output shaft of the horizontal motor 33; the horizontal motor 33 drives the driving sprocket 34, the driving sprocket 34 drives the driven sprocket 32, and the driven sprocket 32 drives the cylindrical rotating shaft 3 to rotate, so that the cable is paid out from the cable reel.

As a preferred embodiment, the horizontal motor 33 is a bidirectional speed-adjustable motor; the purpose of setting up two-way adjustable speed motor is in order to make simple pay-off have the function of receiving the line, strengthens application scope on the one hand, and on the other hand prevents to appear because the cable winding that the unwrapping wire leads to too fast, twists.

As a preferred embodiment, the bottom of the L-shaped strut 1 is provided with an inclined strut 15; because the dead weight of the cable reel is great, the L-shaped pillar needs to be reinforced to a certain extent, and deformation and damage caused by overhigh load are prevented.

The utility model discloses a theory of operation does: before use, the small jack 14 is lowered to the lowest position, and the through hole on the supporting leg 42 of the movable supporting plate 4 is selected according to the axis position of the cable reel to achieve the purpose of adjusting the initial height of the cylindrical rotating shaft 3, wherein the principle of selecting the initial height is that the position of the central hole of the cable reel is slightly higher than that of the roller 22. After the movable supporting plate 4 is fixed, the cylindrical rotating shaft 3 is transversely inserted into the axis of the cable reel, the spokes of the cable reel are aligned with the clamping grooves 51 on the clamping device 5 and screwed down by the threaded rod 52 with the handle, so that the cable reel and the cylindrical rotating shaft 3 are connected into a whole. The small jacks 14 on both sides are slowly lifted, the cylindrical rotating shaft 3 is slowly contacted with the roller 22, the small jacks 14 are continuously lifted, and the cable reel is slowly jacked off the ground. Since the two rollers 22 are arranged in parallel, the cylindrical rotating shaft 3 is just clamped between the two rollers 22 through the V-shaped groove 23 on the box body 21. Meanwhile, the length of the columnar rotating shaft 3 is just equal to the distance between the box bodies 21 on the left and right L-shaped supporting plates, so that the columnar rotating shaft 3 can be just clamped into the box bodies 21 and cannot collide or slide along the length direction of the columnar rotating shaft 3.

After the cable reel is jacked off the ground by the jack, a chain is sleeved outside the driving chain wheel 34 on the output shaft of the horizontal motor 33 and the driven chain wheel 32 on the columnar rotating shaft 3, so that the driving chain wheel 34 is driven by the horizontal motor 33, the driven chain wheel 32 is driven by the driving chain wheel 34, and the columnar rotating shaft 3 is driven by the driven chain wheel 32 to rotate, so that the purpose that the cable is discharged from the cable reel is achieved. Because horizontal motor 33 is two-way adjustable speed motor, consequently can reach the purpose of unwrapping wire or receipts line through changing turning to of horizontal motor 33, can carry out the speed governing according to the cable model simultaneously: the thick cable is slow in speed, the thin cable can be adjusted to be fast in speed, and the situation that the cable is entangled and twisted is prevented.
