A rotation limiting device, comprising a base (10) and a rotating member (20) rotating relative to the base (10); a spiral groove (14) is provided on one of the base (10) and the rotating member (20); a straight groove (24) is provided on the other of the base (10) and the rotating member (24), opposite the spiral groove (14); the start position of the spiral groove (14) is aligned with the start position of the straight groove (24); the end position of the spiral groove (14) is aligned with the end position of the straight groove (24); a rotary shaft (40) is slidably connected between the base (10) and the rotating member (20); one end of the rotary shaft (40) is slidably accommodated within the spiral groove (14); the other end of the rotary shaft (40) is slidably accommodated within the straight groove (24). The rotation of the rotary shaft (40) from the start position to the end position of the spiral groove (14) is greater than 360°. |
