For example, as shown in fig. 6, the two reverse synchronization mechanisms 200 are a first reverse synchronization mechanism 209 and a second reverse synchronization mechanism 210, respectively, wherein the first reverse synchronization mechanism 209 adopts the reverse synchronization mechanism 200 listed in embodiment 1, and the arrangement position of the motor 101 is the same as that in embodiment 1, and the second reverse synchronization mechanism 210 is different from the first reverse synchronization mechanism 209 in that a transmission shaft 206 is provided at the middle of the upper swing arm 201 and a support shaft 207 is provided at the middle of the lower swing arm 202 in the second reverse synchronization mechanism 210, as shown in fig. 6, while in this embodiment, one end of the synchronization shaft 103 is connected to the support shaft 207 provided at the upper swing arm 201 in the first reverse synchronization mechanism 209, one end of the synchronization shaft 103 is connected to the transmission shaft 206 provided at the upper swing arm 201 in the second reverse synchronization mechanism 210, and when the motor 101 is started, the track changing wheels 205 on the same side of the first reverse synchronization mechanism 209 and the second reverse synchronization mechanism 210 can be driven to synchronize, the track changing wheels 205 on different sides act in reverse synchronization.

It is understood that, in this embodiment, the term "side" of the "one side", "the same side" and "different sides" refers to the direction from the middle of the upper swing arm 201 to one end of the upper swing arm 201 as a reference point, i.e., one side.
