Apparatus for controlling string

A string adjusting device, comprising:

• a base unit including a base plate, a cylindrical lower housing provided on the base plate, and an engagement member configured such that one end thereof is fastened to an outer surface of the lower housing and provided to be elastically deformable;
• and
• a rotation unit including a bobbin rotatably installed inside the housing and configured such that a string is wound therearound, a rotation head connected to one end portion of the bobbin, and stop protrusions formed to protrude from an inner surface of the rotation head to be caught on the engagement member.

A string adjusting device, comprising:

• a base unit including a base plate, a cylindrical lower housing provided on the base plate, and an engagement member provided at an upper end of the lower housing to be elastically deformable based on one end;
• and
• a rotation unit including a bobbin rotatably installed inside the housing and configured such that a string is wound therearound, a rotation head connected to one end portion of the bobbin, and stop protrusions formed to protrude from a trajectory where the engagement member is located when the rotation head is rotated below the rotation head.

A string adjusting device, comprising:

• a base unit including a base plate, and a lower housing provided on the base plate, formed in a cylindrical shape, and configured to include stop protrusions formed to protrude;
• and
• a rotation unit including a bobbin rotatably installed inside the housing and configured such that a string is wound therearound, a rotation head connected to one end portion of the bobbin, and stop protrusions elastically deformably provided on a trajectory where the stop protrusions are located when the rotation head is rotated below the rotation head and configured to be caught on the stop protrusions.
