本发明脚轮结构在动作时如图10至图14所示，如图10所示，当使用者欲使脚轮定向使该脚轮不会随意转动时，先踩踏该多功能踏板31的踩踏部311，使该多功能踏板31以该第三枢设件35为枢轴朝踩踏的方向旋转，该多功能踏板31的该第一推抵部312及该第一抵压部313亦随之朝相同的方向旋转，由于该第一推抵部312常态下抵于该第一翘板32的该第一受抵部321，所以在该第一推抵部312旋转的同时亦推抵该第一受抵部321，使该第一翘板32以第一枢设件34为枢轴旋转，该第一翘板32的第一卡制部322亦同步旋转并卡入该第一内齿件21的该第一槽部211，由于该第一翘板32的第一卡制部322被该第一槽部211所卡制，且该第一翘板32通过该第一枢设件34枢设于该主体支架10，所以在该第一翘板32的第一卡制部322被该第一槽部211所卡制时，亦使该主体支架10无法相对于连接杆20旋转，由此达成定向的目的。
同时该第一抵压部313旋转进而抵顶该定向复位踏板51的第四抵压部512，使该定向复位踏板51以该第二枢设件53为枢轴朝推抵的方向旋转，使该定向复位踏板51呈现可踩踏的状态，如图11所示。
如图12所示，当使用者欲使该轮件60同时定向及刹车时，如图11所示继续踩踏该多功能踏板31的踩踏部311，使多功能踏板31以该第三枢设件35为枢轴朝踩踏的方向继续旋转，至该多功能踏板31的第三抵压部315抵接该辅助 刹车件41的第三受抵部411,该辅助刹车件41的第二推抵部412及该第二抵压部413亦随之朝相同的方向旋转，由于该第二推抵部412是抵于该第二翘板42的该第二受抵部421，所以在该第二推抵部412旋转的同时亦推抵该第二受抵部421，使该第二翘板42以该第一枢设件34为枢轴旋转，该第二翘板42的第二卡制部422亦同步旋转并卡入该第二内齿件22的该第二槽部221，该第二翘板42的第三卡制部423亦同步旋转并卡入该轮件60的该限止齿轮63的卡槽631内。
同时该该第二抵压部413旋转进而抵顶该解刹复位踏板52的第三抵压部522，使该解刹复位踏板52以该第二枢设件53为枢轴朝推抵的方向旋转，使该解刹复位踏板52呈现可踩踏的状态(如图12所示)。
另包括第三弹性件73，该第三弹性件73的一端具有一套设部731，该套设部731的两侧分别延伸出两限抵部732和733，限抵部732抵接于第二翘板42的下方，限抵部733抵接于多功能踏板31的卡槽318内，松开该多功能踏板31的踩踏部311,该多功能踏板31在第三弹性件73的弹性作用下，该多功能踏板31以该第三枢设件35为枢轴朝踩踏的反方向旋转，该多功能踏板31的第一推抵部312抵于该第一翘板32的该第二受抵部323，所以该第一推抵部312旋转的同时亦推抵该第二受抵部323，使该第一翘板32以该第一枢设件34为枢轴旋转，直至该第一推抵部312重新抵接于该第一翘板32的第一受抵部321的位置，此时如图13，该多功能踏板31的第一抵压部313旋转进而回到抵顶该定向复位踏板51的第四抵压部512的位置，使该定向复位踏板51以该第二枢设件53为枢轴朝推抵的方向旋转，使该定向复位踏板51也同时呈现可踩踏的状态。
由于该第二翘板42的第二卡制部422为被第二槽部221所卡制，且该第二翘板42通过该第一枢设件33枢设于该主体支架10，所以该第二翘板42的第二卡制部422为该第二槽部221所卡制时，亦使该主体支架10无法相对连接杆20旋转。
由于该第二翘板42的第三卡制部423亦同步旋转并卡入该轮件60的该限止齿轮63的齿槽631内，所以该轮件的限止齿轮63被第三卡制部423所卡制，进而使该轮件60无法旋转，由此同时达成定向及刹车的目的。
如图14和图10所示，当使用者欲解除定向或刹车或定向与刹车的状态时，由于此时该定向复位踏板51和解刹复位踏板52均呈现可踩踏的状态，所以先踩 踏该定向复位踏板51或且解刹复位踏板52的踩踏部511或且踩踏部521，使该定向复位踏板51或且解刹复位踏板52以该第三枢设件53为枢轴朝踩踏的方向旋转，该定向复位踏板51或且解刹复位踏板52的该第四抵压部512或且第五抵压部522亦随之朝相同方向旋转，进而推抵该多功能踏板31的该第一推抵部312和第二抵压部313或且该刹车辅助件41的第二抵压部413，使该多功能踏板踏板31或且该刹车辅助件41以该第三枢设件35为枢轴朝推抵的方向旋转。
该多功能踏板31旋转时该第一推抵部312亦同步旋转，使该第一翘板32的该第一受抵部321失去推抵的力量，进而旋转复位，该第一翘板32的该第一卡制部322亦离开该第一内齿件21的第一槽部211，该第一卡制部322失去该第一槽部211的卡制，进而使该主体支架10呈现得以旋转的状态。
该刹车辅助件41旋转时该第二推抵部412亦同步旋转，使该第二翘板42的该第二受抵部421失去推抵的力量，进而旋转复位，该第二翘板42的该第二卡制部422亦离开该第二内齿件22的第二槽部221，该第二卡制部422失去该第二槽部221的卡制，与此同时该第三卡制部423离开该限止齿轮63的齿槽631，进而使该主体支架10呈现得以转动，轮件60呈现得以旋转的状态。
如图10至图14所示，揭示本发明具脚轮的使用方法，包括：
踩踏该多功能踏板31的踩踏部311，使该多功能踏板31以该第三枢设件35为枢轴旋转，进而推抵该第一翘板32，使该第一翘板32同步旋转，进而使该第一翘板32的第一卡制部322卡入该第一内齿件21的该第一槽部211，使该主体支架10无法相对于连接杆20旋转，实现定向的目的。
