Cable sheath mounting device

The invention discloses a cable sheath mounting device, and relates to the technical field of cable sheath mounting. Existing machines can only process cables with fixed lengths. The cable winding device comprises two racks and a power mechanism, the racks are connected through a supporting plate, the power mechanism comprises an output shaft, the periphery of the output shaft is rotationally connected with a winding mechanism, and when the output shaft rotates, a main gear rotates along with the output shaft to enable an auxiliary gear to wind a spiral sheath on a guide rod on the outer surface of a cable in a rotating mode; a pulling mechanism is installed at the top of the supporting plate, a separating mechanism is installed on the side, close to the pulling mechanism, of the winding mechanism, and when the rotating shaft rotates, a connecting main gear in the pulling mechanism is driven to rotate, and a connecting auxiliary gear rotates along with the rotating shaft, so that a plurality of connecting col
