[0028] Further, the driving assembly includes a support block 15, a motor 16, a support rod 17, a rotating shaft 18, a fixed rod 19, a rotating rod 20, a connecting rod 21 and a transmission assembly 22. The support block 15 is fixedly connected to the top of the base 1. The motor 16 is installed on the top of the support block 15. The support rod 17 is fixedly connected to the top of the base 1.
