A miniature take-up device comprises a support. The support is provided with a rope-gathering disc. One end of the support is provided with a guide pulley. A coaxial-rotation tightening-up pulley and a handle are arranged between the rope-gathering disc and the guide pulley. A ratchet mechanism is arranged between the tightening-up pulley and the handle. A steel wire rope is arranged on the rope-gathering disc and is wound on the tightening-up pulley for a plurality of loops. The end of the steel wire rope is provided with a wire clamper fixation ring. According to the miniature take-up device, through the combination of the rope-gathering disc and the tightening-up pulley, the distance of wire taking up and wire tightening up is greatly increased; through utilization of the miniature take-up device to tighten the wire, wire tightening up work on poles by workers is reduced; meanwhile ground wire tightening workers are also reduced from the original 6-7 workers to 2 workers; the labour intensity of the workers on poles can be effectively reduced; safety is improved; working time is reduced; and work efficiency on wire tightening and wire loosing is comprehensively improved.
