The first threaded rod 1201 passes through the inner movable block 14, and the inner movable block 14 and the first threaded rod 1201 are threadedly connected. The rotation of the first threaded rod 1201 can drive the inner movable block 14 to move.

[0025] The first connecting rod 8 and the corresponding second connecting rod 9 are equal and arranged in parallel. Since the first connecting rod 8 and the second connecting rod 9 are parallel to each other and have the same length, the fixing plate 10 will always remain parallel to the rotating shaft 5 .
