Patent ID: 8745830

Claim:
A fixing structure, for locking an object to be locked having a hook piece, the fixing structure comprising: a rotating element, comprising: a rotating element body; a plurality of bumps, being disposed on the outside of the rotating element body; a first containing space, being disposed inside the rotating element body, wherein when the hook piece is positioned in the first containing space, the object to be locked is not locked in the fixing structure; a second containing space, being positioned in the rotating element body and communicating with the first containing space, wherein when the hook piece is positioned in the second containing space, the object to be locked is locked in the fixing structure; an elastic element, connecting with a bottom of the rotating element, wherein the elastic element is for generating an elastic force when being compressed to push the rotating element body; and a base, comprising: a base body, wherein the rotating element and the elastic element are disposed in the base body; and a trajectory groove, being disposed around the inside of the base body, each of the plurality of bumps being able to move in the trajectory groove, wherein when the bump moves in the trajectory groove, the rotating element body is able to rotatively rise or descend in the base body, and each of the plurality of bumps is correspondingly positioned in a respective position in the trajectory groove; whereby when an external force is added to the hook piece of the object to be locked, the hook piece enters the first containing space and causes the rotating element body to rotate and descend, and causes each of the plurality of bumps to move in the trajectory groove; when the external force is removed, the elastic force generated when the elastic element is compressed causes the rotating element body to rotate and rise such that the hook piece enters the second containing space, and the hook piece of the object to be locked is locked in the fixing structure at this time.
