1. A unidirectional free-pulling data cable, comprising a first wire, a second wire, a wheel core, a follow-up circuit board, a fixed conductive board, a clamping assembly and a hollow housing; the wheel core and the clamping assembly being arranged in the housing; the wheel core being rotatable relative to the housing, the follow-up circuit board being positioned on one side of the wheel core; the fixed conductive board being disposed on one side of the housing corresponding to the follow-up circuit board and electrically connected to the follow-up circuit board;
the first wire that is electrically connected to the follow-up circuit board being wound around the wheel core and exposed out of the housing; one end of the second wire being electrically connected to the fixed conductive board, and the other end thereof being exposed out of the housing;
an elastic member being disposed inside the wheel core, and the opposite side of the wheel core being provided with a wheel cover; the clamping assembly disposed on one side of the housing corresponding to the wheel cover cooperating with the wheel cover to position the wheel core to limit the rotation of the wheel core;
the housing comprising an upper housing and a lower housing that are detachably connected; the wheel core being disposed in the lower housing, and the clamping assembly being disposed in the upper housing,
a fixing pillar being disposed in the lower housing, one end of the elastic member being positioned on the fixing pillar, and the other end thereof being positioned on the wheel core, and
wherein when the wheel core rotates, the elastic member providing the wheel core with a restoring force for rotating back.
