摘要（英）：

The utility model discloses a pay-off rack which comprises a vertical pay-off rack frame. A screw seat is arranged on a plane at the upper end of the vertical pay-off rack frame, a downward vertically movable screw is configured in a screw hole in the middle of the screw seat, a rotary disc with a rotary handle is configured at the upper end of the screw, a support disc with a iron tube supporting hole is connected to the lower end of the screw, and two fixed pulleys are mounted on the inner lower potion of the hole. The pay-off rack has the advantages that the pay-off rack is simple and reasonable in structure and can be used conveniently and reliably; sliding friction is replaced by rolling friction, accordingly, a friction coefficient can be reduced, friction force can be lowered, the pay-off efficiency can be improved, and the like.
