Abstract: A double-pedal double-wheel truckle with independent braking and releasing functions is a truckle for a precision instrument and comprises a body, a rotating & locking device, a truckle body device, a braking device and a bottom cover body. The body is provided for disposing a rotating & locking device, a truckle body device, a braking device and a bottom cover body. With the independent braking and releasing functions of the braking device of the body, the user can easily operate and stably block the rotating & locking device and the truckle body device. The bottom cover body is provided for preventing foreign matters from entering the truckle body device, so that the truckle can be locked from rotation. By such arrangements, it can achieve the objectives, such as easy operation, easy to distinguish braking state, stable braking, reducing noises, strengthening structure and safe usage, etc.
