[0026] The driving assembly 2 comprises a driving member 22 and a second mounting base 21, and the output end of the driving member 22 is connected with the chain 6. Specifically, the output end of the driving member 22 is connected with a gear engaged with the chain 6, and the driving member 22 drives the gear to rotate, thereby driving the chain 6 to move. The top end of the driving member 22 is connected with the second mounting base 21, and the two second mounting bases 21 are respectively connected with the two connecting plates 16. The connecting mode of the second mounting base 21 with the connecting plate 16 is the same as that of the first mounting base 11 with the connecting plate 16, and thus will not be described herein.
