The invention relates to a wire support pay-off rack. The two sides of a fixing ring are respectively connected with one end of a screw, the other end of each screw is connected with one end of a screw sleeve, the other end of each screw sleeve is fixed to a baffle plate, and the two ends of each baffle plate are respectively provided with a bolt barrier shaft. With the wire support pay-off rack, a coiled low-voltage wire can be installed on the upper and lower bolt barrier shafts of the barrier plates and can be fastened through rotation and push-pull of the screws. Therefore, the problem of disorder in the pay-off process is effectively avoided, manpower is reduced, and the working efficiency is improved.
