Abstract
A wrench includes a tool head having a number of teeth formed in a chamber, and a handle having a shaft rotatably engaged into the chamber of the tool head and having a channel laterally formed in the shaft, a stem is engaged into the channel of the shaft, and includes one or more actuators. A follower is slidably received in the channel of the shaft, and includes one or more teeth for engaging with the teeth of the tool head, and for selectively locking the handle to the tool head at selected angular position. The follower includes a space formed by an inner peripheral surface, for engaging with the actuators. One of the actuators may force the teeth of the follower to solidly engage with the teeth of the tool head.
