upwards and downwards by matching with the third threaded rod 613 and the driving block 614, and make the top of the first movable tube 603 and the bottom of the third movable tube 606 closely adhere to each other, and then achieve the purpose of adjusting the initial position of the winding wheel 601 by changing the position of the first movable tube 603, when the magnitude of the pulling force of the distribution wire 3 driving the winding wheel 601 to move needs to be adjusted, by rotating the worm 611, the worm 611 drives the worm gear 612 to rotate, and further the worm gear 612 drives the third threaded rod 613 to rotate, and the third threaded rod 613 is in threaded connection with the driving block 614, the driving block 614 is in threaded connection with the third threaded rod 613 to adjust the distance between the top of the movable rod 605 and the top of the second movable tube 604, i.e. the degree of compression of the second damping spring 607, when the length of the second damping spring 607 is shorter after the position of the winding wheel 601 is fixed, the pulling force required for stably moving the winding wheel 601 upwards is larger, otherwise, when the length of the second damping spring 607 is longer after the position of the winding wheel 601 is fixed, when unbalanced tension is generated at two ends of the distribution wire 3 and the traction force of the distribution wire 3 on the adaptive adjusting assembly 6 is large, the distribution wire 3 can drive the winding wheel 601 to move upwards, the fixed shaft 602 is matched with the first movable tube 603 and the third movable tube 606 to press the second damping spring 607, so that the upward movement of the winding wheel 601 is buffered, the unbalanced tension on the surface of the distribution wire 3 can be adaptively adjusted, the distribution wire 3 and the telegraph pole 1 can be prevented from being damaged due to unbalanced tension, after the distribution wire 3 is wound on the adaptive adjusting assembly 6, the distribution wire 3 is placed in the first clamping groove 405 of the first clamping block 401, the first limiting frame 403 is rotated at the moment, so that the distribution wire 3 is placed between the first clamping block 401 and the second clamping block 404, at this time, the locking assembly 9 locks the first clamping block 401 and the first limiting frame 403, when the distribution wire 3 moves on the inner wall of the first clamping groove 405 due to unbalanced tension, the plurality of transverse grooves are formed on the surface of the rotating roller 407, so that the distribution wire 3 drives the rotating roller 407 to rotate, the rotating roller 407 drives the transmission rod 408 to rotate, and when the transmission rod 408 rotates, the transmission rod 408 drives the wire collecting wheel 411 to rotate and wind the connection rope 412, so that the two connection ropes 412 drive the two movable balls 413 to stretch the first damping spring 414, and the first damping spring 414 is restored and contracted, so that the winding of the wire collecting wheel 411 can be buffered, the movement of the distribution wire 3 is buffered by the transmission rod 408 and the rotating roller 407, when the locking assembly 9 locks the first clamping assembly 4 and the second clamping assembly 5, the fourth threaded rod 902 is rotated on the inner wall of the mounting groove 901, and the fourth threaded rod 902 is moved to the inner wall of the second movable groove 904, at which time the rotating sleeve 906 is rotated on the surface of the fourth threaded rod 902, because the diameter of the bottom of the threaded sleeve 907 is matched with the inner diameter of the limiting arc-shaped pipe 905, and the inner diameter of the bottom of the rotating sleeve 906 is matched with the diameter of the limiting arc-shaped pipe 905, so that when the rotating sleeve 906 drives the threaded sleeve 907 to be in threaded connection with the fourth threaded rod 902, the threaded sleeve 907 drives the rotating sleeve 906 to move downwards until the limiting arc-shaped pipe 905 is arranged between the rotating sleeve 906 and the threaded sleeve 907, and the bottom of the rotating sleeve 906 is contacted with the top of the second fixed block 903, at this time, the rotating sleeve 906 and the threaded sleeve 907 can
