There should be no twisted links when using, and the lower hook frame of the double-row chain should not be turned over. The operator should stand in the same plane as the bracelet wheel to sway the bracelet, so that the bracelet wheel rotates in a clockwise direction, so that the weight can be raised; when the bracelet is reversed, the weight can be slowly lowered.
