Gear Shifting Structure of Power Equipment and Electrically-Driven Tool Comprising Same

A transmission structure of power equipment, comprising:

• a first shaft;
• a first gear and a second gear, concentric with the first shaft, located in different positions in an axis direction of the first shaft, respectively having protrusions formed to face each other, and freely rotating with respect to the first shaft;
• a clutch disposed between the first and second gears to be concentric with the first shaft, coupled to the first shaft in a spline-fit or key-fit manner, to be movable in the axis direction while rotating together with the first shaft, and having latch members respectively protruding in directions of the first and second gears;
• a control member configured to move the clutch in the direction of the first or second gear;
• a second shaft disposed to be parallel to the first shaft;
• and
• a third gear and a fourth gear, concentric with the second shaft, respectively disposed in engagement with the first and second gears in positions respectively corresponding to the first and second gears, and rotating together with the second shaft,
• wherein elastic members respectively pressing the first gear and the second gear to move toward each other, and movement limiting members respectively limiting axial movements of the first and second gears are provided, and
• the protrusion of the first gear or the protrusion of the second gear is latched by one of the latch members of the clutch, by the control member.
