BACKGROUND OF THE INVENTION 
       [0001]    1. Field of the Invention 
         [0002]    The present invention relates to the technical field of bicycles, particularly relates to a pedal kickstand that has the effect of supporting a bicycle. 
         [0003]    2. Description of the Related Art 
         [0004]    Bicycles will all be provided with a kickstand for holding the bicycles upright when not being ridden. Conventional bicycle kickstands are all additionally fixed to the bicycles as an individual component. Conventional bicycle kickstands generally comprise two types, single-pillar type and double-pillar type. A single-pillar type kickstand usually is fixed at the position of the chain stay at the side of the rear wheel, and it can also be fixed at the position of the middle section of the frame at the front end of the chain stay; a double-pillar type kickstand mostly is fixed at the position of the middle section of the frame at the front end of the chain stay. 
         [0005]    Both a single-pillar type kickstand and a double-pillar type kickstand all have certain disadvantages: for a single-pillar type kickstand, the bicycle is stood by forming a supporting surface via the touchdown points of the front wheel, the rear wheel, and the single-pillar kickstand, so, the single-pillar type kickstand faces the outside of the bicycle body while it is fixed to the bicycle, and while riding the bicycle, people may be injured for colliding with the single-pillar type kickstand; for a double-pillar type kickstand, it is comparatively heavy, so, the whole weight of the bicycle is increased. 
         [0006]    For the above mentioned conventional bicycle kickstands have certain disadvantages, the applicant has worked out a better bicycle kickstand, and hereby files a patent application. 
       SUMMARY OF THE INVENTION 
       [0007]    The object of the present invention is to provide a pedal kickstand aiming at the disadvantages of the conventional art, which has the pedal functional and the kickstand functional at the same time, so as to dispense with additionally mounting an individual bicycle kickstand; it not only can reduce the whole weight of the bicycle, but also can reduce the production cost; it also can keep the whole bicycle beautiful, and can guarantee the application effect of the bicycle. 
         [0008]    To achieve the above mentioned object, the present invention adopts the following technical solution. 
         [0009]    The pedal kickstand of the present invention comprises a pedal, and an earth stand capable of being folded mounted to the outer side of the pedal by pin joint; when the earth stand is unfolded outward to stand on the ground, the bicycle can be held upright steadily. 
         [0010]    The present invention is mounted to a bicycle, and the pedal kickstand is connected to the crank of the bicycle; when the earth stand is unfolded outward for a specific angle, the bicycle can be held upright; for the pedal kickstand provided by the present invention directly utilizes the pedal as the kickstand, the potential hazard caused by the conventional kickstand being exposed can be eliminated, and at the same time, it will not cause the weight problem of additionally mounting a kickstand; it is more beautiful as a whole.
