What is a Positive locking ratchet mechanism?

A positive locking ratchet mechanism is a device that allows rotation in one direction while preventing it in the opposite direction, ensuring secure positioning. It typically consists of a ratchet wheel with teeth and a pawl that engages with these teeth to lock the wheel in place. This mechanism is commonly used in tools like socket wrenches and ratchet straps, providing reliable torque and preventing unintended movement. Its design enhances safety and efficiency by maintaining the desired position under load.
