Tips: What is a quick-release ratchet in ratchet socket set?
The ratchet is the most commonly used handle for car socket set. It is a matching handle installed on the socket for pulling the socket. If there is no ratchet, the socket will not work independently.
When using the ratchet, the socket can be locked with a small turning angle and work in a limited space.
The head of the ratchet is designed with a ratchet device, which can realize rapid one-way rotation without leaving the socket and bolt.
The rotation direction of the locking mechanism can be changed by adjusting the locking mechanism. The pawl of the locking mechanism is adjusted to the left, and the bolt or nut can be tightened clockwise in one direction. Adjust the pawl of the locking mechanism to the right to loosen the bolt or nut in one direction and counterclockwise.
The ratchet is easy to use but not strong enough. Do not use a ratchet for final tightening of bolts or nuts. In addition, it is strictly prohibited to apply excessive torque to the ratchet handle. Otherwise the internal pawl structure will be damaged. The professional ratchets are designed with socket locking and quick-release functions, which only require one-handed operation to prevent the automotive socket or extension rod from falling off during use. One-handed steering function is more convenient for operation. When in use, just press the quick-release button, put the socket head into the square tenon of the ratchet wrench and release the lock button. Then the socket will be locked. If you press the lock button again, the socket lock can be released.
