The system includes a toothed gear, a pivoting lever (ratchet) that controls the movement of the gear, as well as other supporting components. This type of mechanism is commonly used in hand tools, clocks, and automated systems to allow motion in one direction while preventing backward movement. | Electronique & Electricité | Facebook

How Ratchets Work A #ratchet is a handle that snaps into one end of a socket by means of a square-drive connector. The other end of the socket fits over a fastener. A #mechanism in the ratchet allows the handle to engage and tighten the fastener when you swing it in a clockwise direction and turn freely when you swing it counterclockwise. A switch on the ratchet reverses the action to loosen the fastener. Video by @podelkindzen #mechanical #gear #tool #engineering #ratcheting #carpentry #carpent
