CASTER CONTROLLED BY MULTIPLE PEDALS AND USE METHOD THEREFOR

Disclosed herein are a multi-pedal-controlled caster and a method for using the caster, the multi-pedal-controlled caster including a main body support, a connecting rod, an orientation mechanism, a braking mechanism, a reset mechanism, a first inner tooth member, a second inner tooth member, a pair of wheel members and three elastic members, wherein the main body support is relatively rotatable and is combined with the connecting rod, and the first inner tooth member and the second inner tooth member are fixedly mounted on the connecting rod. A multifunctional pedal is treaded to push a first warping plate to make the first warping plate clamped into a first recess portion of the first inner tooth member, so that the caster can run in an orientated manner; and the multifunctional pedal is treaded again to push an auxiliary braking member, and then a second warping plate is pushed to make a second clamping portion of the second warping plate clamped into a second recess portion of the second inner tooth member and to make third clamping portions of the second warping plate clamped into limiting gears of the pair of wheel members, so that the caster can be orientated and braked. By means of the method in the present invention, the caster can implement functions including steering, orientation and braking.
