  • the rotary push-pull rope retractor is used on wearable objects that need to be tied, such as shoes, medical protective equipment, etc.
  • the rotary push-pull rope retractor is suitable to be used on shoes to adjust the tightness of the shoe rope.
  • the clockwise direction is the rope tightening direction, but it is not limited to this.
  • the counterclockwise direction can also be set as the rope tightening direction, and in this case, it only needs to change the direction of the biased triangular teeth of the ratchet 21 and the pawl 34, so that the biased direction is opposite to the clockwise rope tightening direction.
