[0037] The use process of the utility model is as follows: when using the utility model, an external power source is connected. When winding the steel strand, the motor 7 is started.

Through the cooperation of multiple springs 23, the chain 21 has a clockwise rotation torque. When the chain 21 rotates clockwise, the auxiliary shaft 17 and the transmission shaft 19 have a clockwise rotation torque through the sprocket 18. The clockwise rotation torque of the transmission shaft 19 causes the clamping plate 20 to press on the steel strand wound outside the steel strand winding drum 11, so that the clamping plate 20 is always pressed on the steel strand when the steel strand winding drum 11 retracts and releases the steel strand. The storage box 12 is provided with a fence-like shape, so that the ends of the steel strands can be easily extended from the storage box 12 in multiple directions, which is convenient for the storage and unloading of the steel strands. When the steel strand reel 11 needs to be replaced, the ends of the steel strands on the steel strand reel 11 are first fixed, and then the pulling block 13 is pulled. The pulling block 13 causes the gear 16 to rotate counterclockwise through the rack 14. The rotation of the gear 16 causes the sprocket 18 to drive the chain 21 to rotate counterclockwise through the auxiliary shaft 17, thereby opening the two clamping plates 20, releasing the restriction of the clamping plates 20 on the steel strand reel 11, and then releasing the longitudinal restriction of the steel strand reel 11 inside the storage box 12, which is convenient for taking the steel strand reel 11 out of the storage box 12.
