ABSTRACT:
A switching device of reduction gear set is coupled to and drive by a planetary gear system for driving an output tool. The switching device includes a casing defining an interior space having an inside surface on which an internal gear is formed. The casing also defines two opposite elongate slots. A switching member is received in the casing and movable between a first position and a second position. The switching member includes a cylindrical body forming an inner ring gear serving as a ring gear of the planetary gear system and engaging with planet gears of the planetary gear system and an outer ring gear which engages with the internal gear of the casing and thus prevents the switching member from rotation when the switching member is at the first position and disengages from the internal gear of the casing and thus frees the switching member to rotate when the switching member is at the second position, the switching member comprising a driving member rotatably fit over the cylindrical body thereof and being axially fixed thereto, the driving member having extensions projecting beyond the casing through and axially movable along the slots thereof thereby by manually moving driving member, the switching member is moved between the first and second positions for changing output speed of the tool.
