Ratchet socket wrench, usually we call it fast wrench, because it is easy to use in automobile maintenance.

Ratchet sleeve has a great advantage that when the size of screw or nut is large or the working position of wrench is narrow, ratchet wrench can be used.

The swing angle of the wrench is very small, and it can tighten and loosen screws or nuts. Turn the handle clockwise when tightening. The square sleeve is equipped with a strut. When the handle is pulled back in the opposite direction, the strut will slide out in the inclined plane of the spur gear, so the screw or nut will not reverse. If you need to loosen the screw or nut, just turn the ratchet wrench to turn it counterclockwise.

It is convenient, labor-saving and time-saving to pull the nut manually by reciprocating swing. It can be loosened and tightened. It has strong applicability and can easily adjust the angle of use

Ratchet mechanism is a one-way intermittent motion mechanism composed of ratchet and pawl. Ratchet mechanism is often used in various machine tools and automata intermittently feed or rotary table rotation, also commonly used in Jack. Ratchet mechanism is used for one-way drive in bicycle, and it is often used to prevent reversal in manual winch. Ratchet mechanism often works with noise and vibration, so its working frequency should not be too high. When using the ratchet, the "rattle" is also caused by this.

Ratchet handle is a common sleeve handle. The sleeve handle is a matching handle installed on the sleeve to pull the sleeve. If there is no matching handle, the sleeve will not work independently.

When the ratchet handle is used, the socket wrench can be locked with a small rotation angle and work in a limited space.
