Abstract

The utility model relates to a bidirectional vehicle, wherein a trammer stand comprises a first lateral bracket and a second lateral bracket, the two lateral portions of the left side and the right side of the first and the second lateral brackets are symmetrical on the trammer stand. When the trammer stand is under folded state, the first and the second lateral brackets are drawn together, the first lateral bracket comprises a front wheel bracket, and a first pushing and grasping pole whose lower portion is rotationally arranged with the upper portion of a first front wheel bracket. The second lateral bracket comprises a second front wheel bracket, and a second pushing and grasping pole whose lower portion is rotationally arranged with the upper portion of the second front wheel bracket. When the trammer stand is under folded state, the upper end face on the first front wheel bracket is butt-jointed with the lower end face of the first pushing and grasping pole, and the upper end face of the second front wheel bracket is butt-jointed with the lower end face of the second pushing and grasping pole.
