1. A gear structure for an electronic lock comprising: a housing including an accommodating chamber in which a controlling unit is disposed, a power supply located adjacent to the controlling unit so as to supply power, a first connecting seat and a second connecting seat which are mounted on two predetermined positions of the accommodating chamber, wherein the first connecting seat has at least one first connection hole, and the second connecting seat has at least one second connection hole, a guiding mount is fixed in the housing proximate to the first connecting seat and the second connecting seat, and wherein the guiding mount has an axial orifice defined on a central position thereof, a shaft is located adjacent to the guiding mount, and a motor holder is located proximate to the shaft;a driving motor fixed in the motor holder of the housing and including a worm rod extending outwardly from one end thereof;a driving gear including a through aperture formed on a central position thereof, a toothed rim arranged around an outer peripheral side thereof, a driving tooth portion disposed on a central section of a bottom end thereof, wherein the through aperture is arranged to insert the shaft of the housing, and the toothed rim is meshed with and driven by the worm rod of the driving motor;a first rotating gear including an opening, wherein the opening is retained with the guiding mount of the housing, and the rotating gear also includes a rotary disc formed on an centrally recessed portion thereof and having an internal face arranged around an inner peripheral wall of the rotary disc, at least two positioning blocks fixed on two predetermined positions of the internal face, and an external toothed periphery meshing with the driving tooth portion of the driving gear;a rotating member accommodated in the rotary disc of the first rotating gear and including a hole, wherein the hole is positioned on an upper section of the guiding mount of the housing, the second rotating gear also includes two flexibly recessed areas defined on an peripheral side thereof opposite to the at least two positioning blocks of the first rotating gear, and each flexibly recessed area has a sliding trench formed on a first predetermined position thereof and a horizontal slot defined on a second predetermined position thereof, the horizontal slot has two opposite notches extending outwardly therefrom and used to accommodate a resilient piece, the resilient piece has two elastic elements disposed on two predetermined positions of one surface thereof and retained in the two opposite notches, such that a central portion of the resilient piece exposes outside each flexibly recessed area and abuts against a biasing element, wherein the biasing element has a slidable portion, a tilted contacting face defined on a front surface of the slidable portion, and a sliding section, between the slidable portion and the biasing element is formed a fixing groove for retaining with the central portion of the resilient piece, such that the biasing element and the resilient piece are driven to cause flexibility, and the biasing element is rotated by the first rotating gear to abut against the at least two positioning blocks so as to return back to an original position;a fitting member including a fitting opening formed therein, wherein an outer peripheral side of the fitting member connects with an inner wall of the hole of the rotating member;a first sensing unit including at least two first coupling feet secured in the at least one first connection hole of the housing;a second sensing unit including at least two second coupling feet secured in the at least one second connection hole of the housing;a rotatable knob including a grip portion, a bar portion formed on one end of the grip portion, a cross hole arranged on a distal end of the bar portion, such that the bar portion of the rotatable knob is inserted and rotated in the axial orifice of the housing, and the bar portion is further inserted into a mouth of a fitting member so that the bar portion is stopped by an inner wall of the housing. 2. The gear structure for the electronic lock as claimed in claim 1, wherein at least two positioning blocks of the first rotating gear are fixed on the internal face. 3. The gear structure for the electronic lock as claimed in claim 1, wherein the cross hole of the rotatable knob controls a locking head of a lock latch.
