Specifically, in the present embodiment, as shown in fig. 1 and 2, the hand wheel fixing assembly 1 includes: the first fixing part is used for fixing the first hand wheel, and the second fixing part is used for fixing the second hand wheel. As shown in fig. 3 and 4, the driving device 2 includes, for the first fixture and the second fixture: the first driving assembly 21 is connected with the first fixing member, and the second driving assembly 22 is connected with the second fixing member, wherein the first driving assembly 21 is used for driving the first fixing member to rotate, and the second driving assembly 22 is used for driving the second fixing member to rotate.
