[0035] The first supporting and fixing mechanism 4 and the second supporting and fixing mechanism 5 have the same structure. Taking the first supporting and fixing mechanism 4 as an example, the first supporting and fixing mechanism 4 includes a first supporting arm 6 and a second supporting arm 9 connected to each other.
