Features
Ratchets are sometimes called ratchet wheels because they contain a rotating gear or rack with angled teeth. Pawls, which are occasionally misidentified as ratchets, are thin protrusions that relax against a ratchet to restrict its motion. When the ratchet is definitely rotated in one direction, the pawl is elevated and moves smoothly between your angled the teeth. When the ratchet’s rotation stops, the pawl rests between the the teeth and makes a clicking noise. Ratchets and pawls that permit rotation in mere one direction cause the pawl and teeth to clash if the ratchet is turned the opposite way.
