Rotary device

A rotary device, comprising:

• a rotatable member, rotatably disposed on a base, wherein the rotatable member comprises a first positioning mechanism and a second positioning mechanism, the first positioning mechanism comprises a first stopping member and a first positioning member, the second positioning mechanism comprises a second stopping member and a second positioning member, each of the first stopping member and the second stopping member comprises a rotating shaft and a stopping portion, the stopping portion is protruded from the rotating shaft, the first positioning member and the second positioning member are respectively rotatably sleeved over the rotating shafts, and the stopping portions are separately correspondingly disposed on one side of the first positioning member and the second positioning member;
• and
• a limiting mechanism, fixed on the base, wherein the limiting mechanism is configured to selectively stop the first positioning member or the second positioning member according to a rotation direction of the rotatable member, wherein
• when the rotatable member rotates along a first rotation direction, the limiting mechanism allows the first positioning mechanism to pass through and the second positioning member is stopped between the limiting mechanism and the stopping portion of the second stopping member, to position the rotatable member;
• and when the rotatable member rotates along a second rotation direction opposite to the first rotation direction, the limiting mechanism allows the second positioning mechanism to pass through and the first positioning member is stopped between the limiting mechanism and the stopping portion of the first stopping member, to position the rotatable member.
