[0045] Principle of the present invention: During use, when the sled 1 needs power to move forward, the key bar 40 is inserted into the connecting plate four 12, the key bar column 33 is inserted into the connecting plate three 11, and the driving motor 24 is started, driving the motor output shaft to rotate, thereby driving the connecting shaft three 39 to rotate, driving the connecting plate four 12 to rotate, driving the connecting plate two 10 and the connecting plate five 23 to move, driving the connecting plate one 9 to move, and then driving the pressure plate mechanism 6 to move. When the connecting plate two 10 moves, it drives the connecting plate three 11 to rotate, thereby driving the connecting shaft two 32 to rotate, and driving another group of symmetrically arranged connecting plate mechanisms 5 to start synchronously at the same time, so that the other group drives the pressure plate mechanism 6 to move synchronously, thereby realizing the forward movement of the sled 1; When steering is required, the electric telescopic rod 22 starts to retract, driving the drive motor 24 to move, driving the connecting shaft 39 to move, driving the key bar column 2 41 and the magnet 2 42 to move away from the magnetic strip 36. The magnet 2 42 is arranged opposite to the magnetic strip 36, and the opposite surfaces are like magnetic poles. Therefore, when the magnet 2 42 is away, the key bar column 33 moves under the pressure of the spring 34, and the key bar plate on the key bar column 33 is no longer in contact with the connecting plate 3 11. At this time, the drive motor 24 is started, driving the motor output shaft to rotate, and then driving the connecting shaft 3 39 to rotate, driving the connecting plate 4 12 to rotate through the key bar 40, driving the connecting plate 2 10 and the connecting plate 5 23 to move, driving the connecting plate 1 9 to move, and then driving the pressure plate mechanism 6 to move, so as to steer the sled 1; When turning in the other direction, the electric telescopic rod 22 starts to extend, driving the drive motor 24 to move, driving the connecting shaft three 39 to move, the key bar 40 is separated from the connecting plate four 12, and the key bar column two 41 is inserted into the key bar groove 38. The magnetic strip 36 drives the key bar column 33 to move under the action of the extrusion force, and the key bar column 33 compresses the spring 34. The key bar column 33 is no longer in contact with the connecting plate three 11. The drive motor 24 starts, driving the connecting shaft three 39 to rotate, thereby driving the key bar column two 41 to rotate, thereby driving the connecting shaft two 32 to rotate, thereby driving a group of connecting plate mechanisms 5 away from the drive motor to start, thereby driving the pressure plate mechanism 6 to move, squeezing the ground, and realizing turning in the other direction.

[0046] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
