[0006] Preferably, the connecting piece is made of elastic material, which allows children to pinch the limiting piece to bend the connecting piece together, thereby disassembling and assembling the wheels.

[0007] Preferably, the rectangular fixed slot and the clamping block are provided with a second screw, the second screw passes through the shell of the rectangular fixed slot by screw thread and enters the clamping block, which can fix the clamping block, and after the second screw is disassembled, the clamping block can be pulled out from the rectangular fixed slot, so that the clamping block can be rotated to make different mounting parts outward.

[0008] Preferably, the middle part of the inner side of the wheel is movably provided with a mounting ring through a bearing, and the mounting ring is connected with the interference connecting column, since the mounting ring and the wheel are connected through the bearing, the wheel can rotate normally.

[0009] Preferably, the interference connecting column is provided with a chamfer on the surface, which can facilitate the insertion of the interference connecting column into the mounting ring of the wheel.

[0010] Preferably, the toy model is provided with a decorative part, which can increase the aesthetic degree of the device.

[0011] Compared with the prior art, the device has the following beneficial effects:

[0012] 1. The device can provide three kinds of disassembly and installation modes for children to play, one of which is interference connection by clamping and fixing the wheel through the interference connecting column, which is the simplest disassembly mode and can be inserted and pulled out directly, the other is clamping and connecting the wheel through the connecting piece and the limiting block, which requires the child to hold the limiting piece with his hand to bend the connecting piece to disassemble, and the third is screw connection through the first screw and the threaded connecting column, which can gradually increase the difficulty of disassembly and installation as the child grows up, and the screw connection requires the use of tools, thereby improving the age range of the device.

[0013] 2. The device can be disassembled and assembled by the parents, when the disassembly and assembly mode needs to be switched, the parents disassemble the second screw through a socket wrench and pull out the clamping block in the rectangular fixed slot, and then install the parts of the connection mode outward according to the required mode, such as installing the wheel by interference connection, which can make the interference connecting column outward, so that the adjustment mode of the device is simple, thereby facilitating the popularization and use.
