A rotation control device for a tool is disposed between a handle and a tool head and includes two ratchet wheels, a spring and two C-shaped snap rings. The two ratchet wheels are symmetrically arranged. When pressed, the respective ratchet wheels will be subjected to the same force and move the same distance, thus making the engagement between the ratchet wheels and the tool head more assured while avoiding the stuck fault and improving the convenience in use. |
