Further, the step of the first slide 311 is adapted to the step of the cable 22 wound around the storage lever 21.
In order to enable the cables 22 to be orderly arranged in the storage rack 2 when the storage rack 2 collects the cables 22, meanwhile, the cables 22 can be smoothed out smoothly, as shown in fig. 5, the arranging device 7 comprises a limiting shell 71 which is slidably connected with the inner cavity of the sliding plate 33, connecting holes are formed in one side, away from the storage rack 2, of the upper portion of the limiting shell 71 and one side, close to the storage rack 2, of the lower portion of the limiting shell 71, a fixing ring 72 fixedly connected with the inner cavity surface of the limiting shell 71 is arranged at the lower portion of the inner cavity of the limiting shell 71, a driven ring 73 is arranged on the outer surface of the fixing ring 72, and a roller 75 which is rotatably connected with the inner cavity surface of the limiting shell 71 is arranged at the upper portion of the inner cavity of the limiting shell 71.

Further, when the limiting device 3 is moved by the driven device 6, since the two sprockets 61 are identical, the rotation speed of the receiving rod 21 and the driven wheel 31 is identical, but as the thickness of the cable 22 wound around the outer surface of the receiving rod 21 increases, the length of the cable 22 wound around the outer surface of the receiving rod 21 increases after one turn of the receiving rod 21, so that the rotation speed of the driven ring 73 gradually increases.
Further, when the driving device 4 drives the limiting device 3 to rotate at a constant speed, the driven wheel 31 rotates to drive the fixed ring 72 to move at a constant speed left and right, so that the fixed ring 72 drives the arrangement device 7 to move at a constant speed left and right, and when the arrangement device 7 moves at a constant speed to one side, the cable 22 is driven to move at a constant speed to one side, so that the cable 22 is uniformly arranged on the outer surface of the storage rod 21.

When the cable 22 is wound, the driven ring 73 rotates under the drive of the cable 22, the driven piece 731 on the driven ring 73 enters from the upper part of the semicircular ring 711, and is separated from the lower part of the semicircular ring 711, and when the cable is wound, the speed of the driven ring 73 is gradually increased, and the driven piece 731 rotates along with the driven ring 73, so that the driven piece 731 does not influence the winding process.
In order to make the driven wheel 31 drive the driven ring 73 to rotate when the cable 22 is wound, and then make the driven ring 73 drive the cable 22 to perform paying-off work, as shown in fig. 9, the positioning piece 74 comprises a second support rod 741 fixedly connected with the outer surface of the driven ring 73, a transmission pin 742 is arranged in the middle of an inner cavity of the second support rod 741, an inclined plane is arranged below the transmission pin 742, a second slide 743 is arranged on the upper portion of the outer surface of the transmission pin 742, a sliding rod 745 in sliding connection with the inner wall of the limiting shell 71 is arranged in the inner cavity of the second slide 743, the sliding rod 745 extends to the outside of the limiting shell 71, a third spring 744 fixedly connected with the inner cavity surface of the second support rod 741 is wound on the lower portion of the outer surface of the transmission pin 742, and limiting teeth 746 are arranged below the transmission pin 742, and the structures of the limiting teeth 746 are communicated with the structures of the connecting disc 232 and the limiting block 2321.

Specifically, when the device performs a winding operation, at this time, the slide rod 745 is located in the vertical chute 7432 at the upper side, the inclined plane at the lower portion of the driving pin 742 faces the direction same as the rotation direction of the limiting tooth 746, on one hand, the driven wheel 31 will drive the driven ring 73 to rotate through the positioning member 74, and since the rotation speed of the driven ring 73 will gradually increase, the rotation speed of the driven ring 73 will gradually be faster than the rotation speed of the driven ring 31, and when the rotation speed of the driven ring 73 is faster than the driven ring 31 to a certain extent, the limiting tooth 746 will jack up the driving pin 742, so that the positioning member 74 will not affect the winding operation of the device during winding.
Further, when the device performs paying-off operation, the sliding rod 745 needs to be pressed to slide the sliding rod 745 along the inner cavity of the second slideway 743, and because the sliding rod 745 can only move up and down along the outer surface of the limiting shell 71, when the sliding rod 745 moves to the inner cavity of the circular arc chute 7431, the driving pin 742 is driven to rotate, when the sliding rod 745 moves to the inner cavity of the vertical chute 7432 positioned at the lower side, the driving pin 742 rotates 180 degrees, the inclined plane at the lower part of the driving pin 742 is the same as the rotating direction of the limiting tooth 746, and when the driven wheel 31 drives the limiting tooth 746 to rotate, the positioning piece 74 drives the driven ring 73 to rotate under the action of the driving pin 742, so that the device performs paying-off operation.
In summary, the specific embodiments thereof are as follows: during paying-off, the transmission device 4 drives the driven wheel 31 to reversely rotate through reverse rotation, then drives the driven ring 73 to rotate along with the driven wheel 31 under the action of the positioning piece 74, when the driven ring 73 rotates, the plurality of driven pieces 731 on the driven ring 73 can be carried out from the lower part of the semicircular ring 711 and are separated from the upper part of the semicircular ring 711, when the driven piece 731 contacts the semicircular ring 711, the two connecting rods 7312 on the driven piece 731 can move to one sides close to each other under the action of the inclined surfaces of the lower part of the semicircular ring 711, at the moment, the spring four 7313 is in a compressed state, and then drives the two arc plates two 7314 to move to one sides close to each other, so that the two arc plates two 7314 fix the cable 22, and thus drive the cable 22 to rotate along with the driven ring 73, and when the driven piece 711 moves to the upper part of the driven piece 731, the semicircular ring 7312 is not limited any more, so that the connecting rods 7312 return to the original positions under the action of the spring four 7313, and then the cable 22 passes through the roller 75 and goes out of the connecting holes on the upper part of the limiting shell 71, so that paying-off work is carried out on the cable 22.
