Abstract

The present invention provides an adjustable wrench with ratcheting function, which comprises a body, a movable jaw, an adjusting device, and a control piece. The body and the movable jaw can drive an object to be driven. The adjusting device adjusts lateral displacement of the movable jaw. The control piece is switchable between a first position and a second position. When the control piece is at the first position, the movable jaw is not allowed to take ratcheted movement with respect to the body. When the control piece is at the second position, the movable jaw is allowed to take ratchet movement with respect to the body. Through the arrangement of the control piece directly corresponding to the adjusting device, the present invention avoids the needs of additional component to provide controls to ratcheted movement, so that the present invention may achieve the ratcheting function of the adjustable wrench with less components and a structure-simplified design.
