Abstract:
A ratchet screwdriver. The clutch assembly (20) is disposed in the grip handle (10) and is sleeved on a main shaft (11) of the grip handle (10). The control assembly (30) is then movably disposed on the grip handle (10), so that the control assembly (30) moves to a first position, a second position, or a third position relative to the grip handle (10). When the control assembly (30) is located at the first position, the control assembly (30) can control a clutch assembly (20) to allow the main shaft (11) to be located at a first gear position. When the control assembly (30) is located at the second position, the control assembly (30) can control the clutch assembly (20) to allow the main shaft (11) to rotate along a first rotation direction, so as to form a second gear position. When the control assembly (30) is located at the third position, the control assembly (30) can control the clutch assembly (20) to allow the main shaft (11) to rotates along a second rotational direction, so as to form a third gear position, thereby achieving a beneficial effect for facilitating operations.
