A rotational tool locking device includes a handle, a drive head, a locking assembly, and an operating button. The drive head is pivotally mounted at one end of the handle, and the locking assembly is arranged between the handle and the drive head. The operating button is set on the handle and can control the locking assembly to be in a fixed or released state relative to the drive head. When in the released state, the drive head can be easily rotated relative to the handle to a specific angle, presenting different pitch positions.
