Abstract:
1. A rotation control device for a tool comprising: a handle with two first ratchet portions; a tool head pivotally connected to the handle and having a second ratchet portion; two identical ratchet wheels disposed between the handle and the tool head, wherein the two ratchet wheels are selectively adjusted between a close position where the two ratchet wheels are abutted against each other and a separated position where the two ratchet wheels are separated and located away from each other, wherein each of the ratchet wheels is provided with a ratchet portion on an outer periphery thereof, a receiving groove in an inner surface thereof, and a protrusive press portion on an outer surface thereof, wherein the ratchet portions of the two ratchet wheels are selectively engaged with the second ratchet portion of the tool head or simultaneously engaged with the first and second ratchet portions, wherein the press portion of each of the ratchet wheels is smaller in outer diameter than the ratchet portion of the respective ratchet wheels, wherein when in the close position, the ratchet portions are engaged with the second ratchet portion of the tool head with the handle and the tool head pivotable with respect to each other, and wherein when in the separated position, the ratchet portions of the ratchet wheels are engaged with the first and second ratchet portions simultaneously with the handle and the tool head fixed in a non-rotatable manner to each other; and a spring disposed between the two ratchet wheels and having two ends pressed against receiving grooves of the two ratchet wheels to maintain the two ratchet wheels in the separated position in normal conditions.
