[0023] In this embodiment, two connecting plates 111 are provided at the top of the support base 11. The connecting plates 111 are arranged obliquely upward. The two connecting plates 111 are arranged symmetrically left and right at intervals. The left and right sides of the two top plates 12 are respectively connected to the connecting plates 111.
