Abstract

This invention relates to a ratchet wrench. Two spring-mounting pieces are extended symmetrically from the top of the stop block which is installed in the second open chamber of the wrench body; and two springs are fitted on the spring-mounting pieces between the two sides of a connection block respectively; the connection block is pre-assembled with the stop block in one-single integrated part. A cover piece is used for covering the first and second open chambers, and for fastening the ratchet wheel on the wrench body at the same time to simplify the assembly structure. When the stop block is turned together with the switching member for changing direction, the counteraction design of the two springs between the connection block on the top of the stop block will provide a pulling force and pushing force on the stop block with a larger movement space; meanwhile a first pushing device installed on the rear end of the second open chamber will provide a pushing action on the switch member. These three spring forces in three directions will produce a louder sound when the wrench is reversely turned to restore the stop block. With this design, the restoration of the stop block can be more ensured, and the switching action can be more recognizable.
