1. An apparatus for generating power using wind energy, comprising blades for receiving the wind energy, further comprising: a plurality of connecting shafts arranged around a boss and rotatably supported by the boss, each of the connecting shafts extending radially and supporting an associated one of the blades; pinions each fitted around an associated one of the connecting shafts to rotate along with the associated connecting shaft; rack housings each fixedly mounted to the boss near an associated one of the pinions; rack gears each slidably received in an associated one of the rack housings and engaged with an associated one of the pinions; springs each fitted around a portion of an associated one of the rack gears extending beyond the rack housing receiving the associated rack gear and adapted to urge the associated rack gear toward an end of the associated rack gear protruded from the associated rack housing; and spring force adjusting knobs each threadedly coupled to the protruded end of an associated one of the rack gears and adapted to adjust a spring force of an associated one of the springs, whereby each of the blades is angularly shifted about an axis orthogonal to a rotating shaft for the blades in response to a variation in a pressure of wind applied to the blades. 2. The apparatus according to claim 1, wherein each of the blades is eccentrically arranged with respect to an associated one of the connecting shafts. 3. The apparatus according to claim 1, further comprising: wind direction sensing means for sensing a variation in the direction of wind applied to the blades, the wind direction sensing means including a vertical shaft, a wind direction indicating member fixedly mounted to an upper end of the vertical shaft and adapted to change an orientation thereof in response to a variation in the direction of wind applied to the blades while correspondingly rotating the vertical shaft, a cam plate mounted to a desired portion of the vertical shaft to rotate simultaneously with the rotation of the vertical shaft, and a micro switch adapted to come selectively into contact with a periphery of the cam plate in accordance with the rotation of the cam plate, thereby generating an electrical signal; pivoting means for pivoting the rotating shaft in response to the wind direction variation sensed by the wind direction sensing means, thereby changing an orientation of the blades, the pivoting means including a housing arranged to support the rotating shaft while being rotatable in response to the wind direction variation to change an orientation of the rotating shaft, and an electromagnet activated by the electrical signal from the micro switch to change an orientation of the rotating shaft; and braking means for restraining the rotation of the housing in response to the activation of the electromagnet.
