(2) the shifting block 312 can rotate once in the direction of D2 to reach the position P2, and continue to rotate in the direction of D2 until it touches the second rotating piece 32;
(3) the shifting block 312 drives the second rotating member 32 to rotate continuously in the direction D2, and after rotating a certain degree, the second rotating member reaches the position P3, and both of them can rotate continuously in the direction D2.
(4) When the shifting block 312 drives the second rotating member 32 to rotate to the position P4 along the direction D2 and continue to rotate in the direction, the second rotating member 32 touches the limiting boss again and causes the first rotating member 31 and the rotating shaft 2 of the device to stop moving, so that the second structural member reaches the maximum rotation angle position in the direction D2 relative to the first structural member 1.
