The two limiting members 13 are spaced apart corresponding to the second shaft hole 121; that is, they are symmetrically arranged on both sides of the second shaft hole 121 with the second shaft hole 121 as the center. In addition, the two limiting members 13 are located in the annular limiting member 114 . Since the two limiting members 13 are slidably disposed on the first fixed side 122, the two limiting members 13 have a first relative position P1 and a second relative position P2. Among them, when the two limiting members 13 are at the first relative position P1, the two limiting members 13 are engaged with the annular limiting member 114; and when the two limiting members 13 are at the second relative position P2 , the two limiting members 13 are not engaged with the annular limiting member 114; wherein, the second direction D2 is perpendicular to the first direction D1.
