The swinging rod is controlled to swing, and the middle position of the pulling rod is pivotally coupled with the positioning plate fixed to the vehicle platform, and the positioning rod is convexly disposed on one side of the pulling rod corresponding to the positioning plate, and is disposed on the positioning plate. Then, the positioning protrusions corresponding to the triggering rod are arranged with a plurality of positioning holes; thereby, the movement of the truck can be changed to one-wheel, two-wheel or three-wheel mode to walk on the ground to reach a different venue 10121481# single number Α 0101 3 Page / Total 23 pages 1012047671-0 [0004] M441602, the benefit of different needs adjustment. However, the “Carriage Structure” of the M42654G of the China R&D application in the previous research and development application can effectively adjust to a single wheel, two-wheel or three-wheel type according to different venues and different usage requirements, so as to facilitate the use. The cost of purchasing different types of trucks is saved. However, the "transporter structure" of the original announcement No. M42654 of the previous research and development application of the present author is based on the shaft, the flap, and the lever. The connection with the positioning plate, and the positioning convex portion of the positioning plate, and the positioning positioning of the positioning holes provided by the positioning convex portion of the corresponding positioning plate of the positioning rod can achieve the transportation of the vehicle according to different venues. Different use requirements are adjusted to different use modes such as early wheel or double wheel or second wheel. The connection structure between the perch shaft, the plate moving piece, the plate moving rod and the positioning plate is complicated, and there are many components, so it is necessary to manufacture. It costs a lot of cost and more assembly man-hours, and because of its many components, it is easy to occur when the use is implemented, such as the shaft, the pulling piece, the pulling rod and the positioning plate. There are some disadvantages such as looseness, especially between the pulling rod and the positioning plate, the pulling rod is slightly pulled outward, so that the positioning convex portion of the pulling jaw can be disengaged from the positioning hole of the positioning plate. If the lever is accidentally bumped, it is easy to release the positioning state of the button and the positioning (4), resulting in unsafe use, and the first-auxiliary wheel is fixed on the _, therefore, when the user When the truck is to be steered, the first auxiliary wheel is fixed on the arbor and cannot be freely rotated, which results in the lack of steering of the truck.
