[0031] Working principle: Before using this four-way vehicle track with guidance, it is necessary to first check the overall situation of the device to ensure that it can work normally. According to Figure 1 - Figure 6As shown in the figure, by arranging the guide rail assemblies 2 on both sides of the mother rail 102 and the reversing rail 103, the four-way vehicle body 104 can be guided by the two track edges 201 when walking. When installing the track edge 201, the track edge 201 is attached to one side of the mother rail 102 or the reversing rail 103, and then the mounting plate 202 is attached to the track edge 201, so that the positioning block 203 is engaged with the positioning groove 204. The mounting block 208 can be pushed to move. The movement of the mounting block 208 drives the movement of the movable rod 205. After the movable rod 205 moves, it slides on the movable ring 207 and compresses the telescopic spring 206, so that the rotating plate 212 can pass through the through groove 213. After the rotating plate 212 passes through the through groove 213, the mounting block 208 can be rotated, so that the movable ring 207 rotates on the fixed sleeve 209 through the sliding connection between the limit ring 210 and the annular groove 211, so that the rotating plate 212 is staggered from the through groove 213, and the limit block 214 on the rotating plate 212 is aligned with the limit groove 215 inside the mother rail 102 or the reversing rail 103. Then the mounting block 208 can be released. Under the action of the telescopic spring 206, the limit block 214 is engaged with the limit groove 215, so that the track edge 201 can be fixed to one side of the mother rail 102 or the reversing rail 103 through the mounting plate 202 and the rotating plate 212, which is convenient for installing the track edge 201. By means of the guide rail assembly 2, the self-guidance of the walking wheels can be cancelled and changed to guide rail guidance, so as to cancel the gap between the reversing rail 103 and the mother rail 102, and the height difference between the mother rail 102 and the sub-rail 101, and it is convenient for the user to install the track edge 201, convenient for transformation, and improves the practicability;

[0032] When installing the track edge 201, when pushing the mounting block 208 to move, the push plate 226 is pushed to move. After the push plate 226 moves, it can slide on the guide rod 227 for positioning. After the push plate 226 moves, it drives the connecting rod 225 to rotate. After the connecting rod 225 rotates, it can push the two connecting frames 224 to move, so that the two connecting blocks 222 approach each other, driving the positioning rod 218 to slide on the fixed block 217 and stretch the return spring 221. After rotating the mounting block 208, the mounting block 208 and the push plate 226 are released. Under the action of the telescopic spring 206, the limit block 214 is engaged with the limit groove 215. The movement of the mounting block 208 can drive the positioning rod 218 to align with the card slot 220 on the support rod 219, so that the return spring 221 can restore its deformation, and the positioning rod 218 is engaged with the card slot 220, so as to position the mounting block 208. Furthermore, after the track edge 201 is installed and fixed, the mounting block 208 can be positioned, avoiding the accidental movement of the mounting block 208 causing the movement of the track edge 201, improving the reliability of the installation of the track edge 201, and being convenient for the user to operate, improving the convenience.
