Description

Technical Field

[0001] The utility model relates to the technical field of data line devices, in particular to a double-wire pulling device with controllable main body position. Background Art

[0002] Retractable data cables (including single-pull cables and double-pull cables) are popular among many users because they can be rolled up to avoid being scattered and entangled, and are easy to carry. Retractable data cables generally include a housing, a wheel core assembly (with a spring and a positioning guide mechanism), wires, circuit boards, circuit boards, etc. The wires are wound around the wheel core and can be pulled out. After the pulled-out wires are released, the wheel core is driven to rotate by the potential energy of the spring to retract the wires. However, the current retractable data cables have the following problems: one side of the single-pull cable is fixed and the other side is movable, so the main part can only be fixed in one position; the double-pull cable usually extends or retracts on both sides at the same time, so the main part will always remain in the middle position. This structure in which the position of the main part is uncontrollable and unadjustable leads to some problems in the use of the retractable data cable, such as the main part will be suspended when plugged into a computer or wall plug, and the wire will be damaged due to excessive weight over time; sometimes the main part cannot be placed in a suitable position on the desktop, causing chaos on the desktop. Although some double-pull telescopic data cables can achieve asynchronous free telescoping on both sides, their implementation structure is relatively complex and prone to malfunction and jamming.
