A ratchet is a mechanical device which allows continuous linear or rotary motion in only one direction while stopping motion in the opposite direction. Ratchets are widely used in machinery and equipment. A rachet contains a round gear or a linear rack with the teeth, and a pivoting, spring-loaded finger known as a pawl (or click, in clocks and watches[1][2]) that engages the teeth. One’s teeth are uniform but asymmetrical, with each tooth having a moderate slope using one edge and a much steeper slope on the various other edge.

When the teeth are relocating the unrestricted (i.electronic. forward) direction, the pawl quickly slides up and over the gently sloped edges of the teeth, with a spring forcing it (often with an audible ‘click’) in to the depression between the teeth since it passes the suggestion of each tooth. When one’s teeth move in the contrary (backward) direction, however, the pawl will capture against the steeply sloped edge of the 1st tooth it encounters, Ratchets Wheel thereby locking it against the tooth and stopping any further motion for the reason that direction.
