A handle is adjustable in a locating angle thereof and is provided at the front end thereof with a receiving slot having an inner hole for receiving a spring and an urging block. The urging block is provided with a horizontal long slot having a front inclined plane. The handle is provided with a through hole passing through the inner hole. The through hole receives a spring and a press rod having a front inclined plane, a straight section passing through the horizontal long slot. A hand tool head is provided at the rear end thereof with a protrusion which is pivoted in the receiving slot and is provided with a retaining portion capable of joining with the top of the urging block. When the press rod is extended, the urging block is urged by the front inclined plane of the press rod so as to locate the hand tool head. The hand tool head is prevented from the free fall by the elastic force of the compressed spring. When the press rod is pressed to displace downward, the urging block displaces inward.
