 In the present invention, since the left handlebar 112 is pivotally connected to the connecting member 110, that is, the first biplane shaft 134 sequentially penetrates the through hole 133 of the connecting member 110, the through hole 121 on the left handlebar 112, and the left inner tube 128. The first long hole 129 and the through hole 125 of the left magnet sleeve 123 are then sequentially passed out in the reverse order described above. Therefore, when an external force acts on the left sliding sleeve 131, since the left handlebar 112, the left magnet sleeve 123 and the connecting member 110 are relatively fixed, the left cylindrical pin 127 moves in the long holes 122, 124, thereby driving the left spring 126. Compressed, at this time, the left inner cylinder 128 has a room for moving in the direction of the left handlebar 112, so that the left inner cylinder 128 is also moved along the first biplane axis 134, so that the first circular hole 181 is in the first pair The position of the plane axis 134 corresponds to the position at which the left handlebar can be rotated relative to the first biplane axis 134, thereby achieving folding of the left handlebar 112. The process of folding the right handlebar is the same. When it is necessary to return the folded handlebar to the riding state, simply pull the handlebar firmly to fix the handlebar to the horizontal riding position by the spring force.

 After the left handlebar 112 is folded, in order to avoid accidentally causing the handlebar to sway, a non-rotation cylindrical magnet is also provided in the present invention.
