As a further improvement of the invention, the upper layer support frame is connected with the lower layer support frame through a front support and a rear support.
As a further improvement of the invention, the front support, the rear support and the lower layer support frame are fixedly connected through bolts, flat gaskets and elastic gaskets.
As a further improvement of the invention, the upper support frame is also fixed with a number plate, and the number plate is fixed on the upper support frame through a self-plugging rivet.
As a further improvement of the invention, the two ends of the lower layer support frame are respectively provided with rollers in a rotating way.
As a further improvement of the invention, the bottom surface of the train connection tie rod is provided with travelling wheels.
As a further improvement of the invention, the front support and the rear support are provided with support blocks at both ends for supporting the vehicle body.
The invention has the technical effects that: the invention has simple, reasonable and ingenious structure, adds a group of limiting supports at the rear part through digital-analog analysis of a plurality of car bodies, can be suitable for different car types, and simultaneously sets the guide opening at the upper part of the limiting support, so that the car bodies are limited through the limiting supports and fall into the positioning pins when in switching, thereby effectively reducing errors.
