[0021] like Figure 3 As shown, gears 204 are mounted on both ends of the main shaft 203 and fixed by pins.

[0022] like Figure 2 and Figure 3 As shown, the guide wheels 208 are installed on both sides of the main support plate 206. In some embodiments, the guide wheels 208 are fixed to the main support plate through guide wheel supports 214 and axles 215, and the guide wheel supports 214 and the main support plate 206 are fixed with bolts.

[0023] like Figure 3 As shown, the push rod 209 is installed at the rear end of the auxiliary pallet 207, and a hinge 210 is provided between the main pallet 206 and the auxiliary pallet 207. The auxiliary pallet 207 can be raised and lowered freely. In order to prevent the push rod 209 from blocking the wheels from traveling to the main pallet 206, a groove is provided on the base surface. When the moving mechanism 2 is in the starting position, the auxiliary pallet 207 and the push rod 209 are placed in the groove.

[0024] like Figure 2 and Figure 3 As shown, the vertical plate 205 is welded and fixed on the main support plate 206 , and a reinforcing rib plate 211 is provided between the vertical plate 205 and the main support plate 206 to increase the connection strength between the vertical plate 205 and the main support plate 206 .
