Pawl is a mechanical component commonly used in various machines and devices. It functions as a type of latch or catch that allows movement in one direction while preventing it in the opposite direction. This feature is essential in applications like clocks, bicycles, and industrial machinery, where controlled movement is necessary. Typically made from metal or durable plastic, a pawl works in conjunction with a ratchet mechanism. When the ratchet turns in one direction, the pawl engages with its teeth, allowing movement. However, when the ratchet attempts to turn in the opposite direction, the pawl locks in place, ensuring stability and safety in the system.
