NettetRatchet (device) (16580 views - Mechanical Engineering) A ratchet is a mechanical device that allows continuous linear or rotary motion in only one direction while preventing motion in the opposite direction. Ratchets are widely used in machinery and tools. Though something of a misnomer, "ratchet" is also often used to refer to ratcheting ... NettetThe most common cable tie consists of a flexible nylon tape with an integrated linear ratchet gear rack, and on one end a pawl within a small open case. Once the pointed tip of the cable tie has been pulled through the case and past the ratchet, it is prevented from being pulled back unless a large amount of force is applied; the resulting loop may only …
