Claim:
1. A stair-climber, comprising: a base; a first inclination unit having a front end disposed at a front end of the base and slidable forward and backward; a second inclination unit having a bottom surface pivotally connected to a top end of the first inclination unit and having a rear end pivotally connected to a rear end of the base; an inclination unit regulator disposed between the front end of the first inclination unit and a front end of the second inclination unit; a step unit disposed at the second inclination unit and having a driving source and multiple steps rotatable pivotally relative to the second inclination unit; a step regulator disposed at the second inclination unit and connected to the steps of the step unit such that the steps are each oriented at a specific angle relative to the second inclination unit; a sensor disposed at the rear end of the second inclination unit to sense a user's feet on the multiple steps and send a sensing signal; and a control unit electrically connected to the driving source of the step unit and the sensor to receive the sensing signal of the sensor and determine, with reference to a sensing result, whether to stop the driving source from operating.
