Abstract
An impact drill includes an output shaft capable of rotating around a first axis and moving along the first axis, a housing, a first impact block fixedly connected to the output shaft, a second impact block, a stopping element for stopping the output shaft from moving backward, and a movable element mounted on the housing. The housing is formed with a through hole for accommodating the movable element. The through hole passes through the housing in a first line and the movable element is capable of moving to a first position and a second position along the first line. When the movable element moves to the first position, the movable element prevents the output shaft from moving backward. When the movable element moves to the second position, the movable element allows the output shaft to move backward.
