  • Apparatus for tying knot and method thereof
    Patent number: 6938934
    Abstract: A knot tying apparatus includes a thread holding frame having a longitudinal axis. The thread holding frame includes an engaging arm having a catch end positioning aligned with the longitudinal axis for slidably engaging a tying thread in position; a thread holder having a rounded bottom end axially extended from the longitudinal axis and an arc-shaped holding groove communicating with the rounded bottom end for slidably holding the tying thread to form a loop thereof while the tying thread is capable of being released at the rounded bottom end of the thread holder, and a resilient element provided between the thread holder and the engaging arm such that the engaging arm is capable of bending towards the thread holder to reduce a distance between the catch end and the holding groove for providing a tension force on the loop of the tying thread.
