The first guide wheel groove 8 is adapted to the first guide wheel 9. A pushing cylinder 2 is hinged between the rear end of the base 1 and the middle of the pushing frame 3. A connecting frame 4 is hinged at the rear end of the pushing frame 3. The connecting frame 4 is fixedly connected to the rear end of the first-level platform 5. When the pushing cylinder 2 is actuated, it will push the pushing frame 3 to flip upward, thereby driving the rear end of the first-level platform 5 to move upward and forward through the connecting frame 4. Under the cooperation of the first guide wheel 9 and the first guide wheel groove 8, the first-level platform 5 will not derail, thereby achieving the purpose of pushing up the first-level platform 5.
