[0003] The existing data line elastic pulling device stores the data line through a reel, generally winds the whole data line on the reel, and winds the two ends of the data line on the outer wall of the reel. When pulling the data line, the two ends of the data line need to be respectively grabbed and pulled outwards, which increases the length of the data line and increases the occupied area of the reel. After miniaturization, the storage length is insufficient, and the traditional data line pulling device generally uses a spring buckle to fix the data line. After long-term use, the locking effect of the buckle may decrease, and it is inconvenient to finely adjust the stretching length of the data line.

[0004] Therefore, in view of the problems that the wire winding of the data line elastic pulling device needs to be improved and it is inconvenient to adjust the stretching length of the data line, a new type of data line elastic pulling device is developed to optimize the wire winding effect, improve the space utilization, and finely adjust the stretching length of the wire.
