[0018] A further improvement of the utility model is that the fixed column is rotatably arranged in the positioning groove through a bearing; one end of the return spring is connected to the outer ring of the bearing. The return spring provides a winding force for the data cable to be wound around the fixed column; the fixed column rotates freely on the inner ring of the bearing, providing a synchronous rotation capability for taking and placing the data cable, thereby reducing the wear between the data cable and the fixed column.

[0019] It can be seen from the above technical scheme that the beneficial effects of the utility model are: the data cable is wound around the fixed column and connected to the return spring to form a rewinding force, so that the loose data cable can be kept in a wound state on the fixed column; the sliding ring clamps the wound data cable under the action of the spring member 1 to prevent it from loosening at will.
