1. An auxiliary rope knotter comprising:
- an interior formed with a first through hole, a second through hole, a first locking groove and a second locking groove;
wherein;
the first through hole, the second through hole, the first locking groove and the second locking groove are parallel with each other;
in a cross-sectional face of the auxiliary rope knotter, the first through hole and the second through hole have a first center connecting line, and the first locking groove and the second locking groove have a second center connecting line;
the second center connecting line intersects the first center connecting line;
in a cross-sectional face of the first locking groove and the second locking groove, each of the first locking groove and the second locking groove has an opening which has a width smaller than a width of each of the first locking groove and the second locking groove;
each of the first through hole and the second through hole has a diameter greater than the width of each of the first locking groove and the second locking groove;
each of the first locking groove and the second locking groove is formed with a first extension wall protruding outward and a second extension wall protruding outward;
tops of the first extension wall and the second extension wall are spaced from each other through a predetermined distance and form the opening;
a rope is inserted through the opening into the first locking groove and the second locking groove; and
the first extension wall and the second extension wall press the rope to increase a friction between the rope and an inner wall of each of the first locking groove and the second locking groove.

Abstract
An auxiliary rope knotter includes an interior formed with a first through hole, a second through hole, a first locking groove and a second locking groove which are parallel with each other. In the cross-sectional face of the auxiliary rope knotter, the first center connecting line formed by the first through hole and the second through hole intersects the second center connecting line formed by the first locking groove and the second locking groove, such that the rope is easily knotted by the auxiliary rope knotter.
