Abstract
A reversible ratchet-type wrench includes a handle and a head extended from the handle and having a hole. A web is defined between the handle and the head, and a cavity is defined in the web and communicated with the hole. The web further includes a compartment having a first end communicated with the cavity and a second end communicated with outside, thereby leaving a bridge in the web. A drive member is rotatably mounted in the hole of the head. A
pawl is mounted in the cavity and includes a first side with ratchet teeth for releasably engaging with teeth on an outer periphery of the drive member. A switch member includes a turn-piece for manual operation and an actuating plate extended from the turn-piece and rotatably received in the second end of the compartment of the head. The switch member is switchable between two positions for changing ratcheting direction of the drive member. A
biasing arrangement is mounted in the cavity and between the pawl and the actuating plate for biasing the ratchet teeth of the pawl to engage with the teeth of the drive member.
