A housing for a hand tool has a head, a handle and two positioning devices. The head is composed of two half casings each having a first adjusting base with a recess. The handle is pivotally attached to the head and is composed of two half casings each having a second adjusting base with a recess. The positioning devices are respectively mounted between the aligning recesses of the first and second adjusting bases on the head and the handle. Each positioning device has a pressing disk, a pressed disk and a biasing member. Each disk has a guiding block and a positioning block. The guiding block is formed on the disk and has two curved guiding edges selectively abutting against one end of the positioning block on the abutting disk. With such an arrangement, the housing can be adjusted between two positions easily and conveniently.
