Ratchet wrench

Abstract

A ratchet wrench is provided, including a main body, a driving member, a restricting member, a switching member and an elastic abutting assembly. The main body has a first receiving, chamber, a second receiving chamber and a third receiving chamber which is communicated with the first receiving chamber and the second receiving chamber. One end of the second receiving chamber is formed with a larger diameter section, and the other end of the second receiving chamber is formed with a small diameter section. The driving member is rotatably assembled within the receiving chamber. The restricting member is disposed in the third receiving chamber and limitable to a rotational direction of the driving member. The switching member is rotatably disposed within the second receiving chamber and includes a rotatable member and a projection which extends from the rotatable member. The rotatable member is received in the larger diameter section and the projection is received in the small diameter section. A bottom of the ratchet wrench of this invention is smoothly rotatable and the ratchet wrench effectively prevents the bottom from departing from the main body, which increase durability and efficiency.
