Abstract
A rotation angle limiting mechanism includes: a turntable, wherein at least one fitting structure is disposed on the turntable; and a moving member, wherein a first limiting structure and a second limiting structure are disposed on the moving member; the turntable rotates and drives the moving member to move so that the fitting structure abuts against one of the first limiting structure or the second limiting structure; the turntable is at a first extreme position when the fitting structure abuts against the first limiting structure; and the turntable is at a second extreme position when the fitting structure abuts against the second limiting structure.
Claims18
A rotation angle limiting mechanism, comprising:
- a turntable, wherein at least one fitting structure is disposed on the turntable;
- and
- a moving member comprising a groove and an opening extending radially through the moving member, wherein:
- a first limiting structure and a second limiting structure are disposed on the moving member;
- the turntable rotates and drives the moving member to move so that the fitting structure abuts against one of the first limiting structure or the second limiting structure;
- the turntable is at a first extreme position when the fitting structure abuts against the first limiting structure;
- and the turntable is at a second extreme position when the fitting structure abuts against the second limiting structure;
- and
- the fitting structure rotates from an outer periphery of the moving member to the groove through the opening when the turntable rotates from the first extreme position to the second extreme position, and the fitting structure rotates from the groove to the outer periphery of the moving member through the opening when the turntable rotates from the second extreme position to the first extreme position.
