A retracting mechanism, comprising: a body including a first path and a second path; a catching member and a connecting member connected to each other; a supporting member connected to the connecting member; and a resilient member for applying an elastic restoring force to the catching member; wherein the catching member and the body are movable with respect to each other through the second path, and the supporting member includes a supporting portion in the first path; and wherein the first path includes a guiding section and a first bent section adjacent to the guiding section, and the second path includes a linear section and a second bent section bent with respect to and in communication with the linear section; and wherein the supporting portion of the supporting member is moved from the guiding section of the first path of the body into engagement with the first bent section when one of the body and the catching member reaches a first predetermined position with respect to the other by being moved in a first direction; and wherein the catching member is moved from the linear section of the second path of the body into engagement with the second bent section to maintain the elastic restoring force of the resilient member, when the one of the body and the catching member reaches a second predetermined position with respect to the other by being further moved in the first direction, the elastic restoring force acting in a second direction, characterized in that the supporting member and the connecting member are pivotally connected by a pivotal connection portion, and the pivotal connection portion is in the second path. a body including a first path and a second path; a catching member and a connecting member connected to each other; a supporting member connected to the connecting member; and a resilient member for applying an elastic restoring force to the catching member; wherein the catching member and the body are movable with respect to each other through the second path, and the supporting member includes a supporting portion in the first path; and wherein the first path includes a guiding section and a first bent section adjacent to the guiding section, and the second path includes a linear section and a second bent section bent with respect to and in communication with the linear section; and wherein the supporting portion of the supporting member is moved from the guiding section of the first path of the body into engagement with the first bent section when one of the body and the catching member reaches a first predetermined position with respect to the other by being moved in a first direction; and wherein the catching member is moved from the linear section of the second path of the body into engagement with the second bent section to maintain the elastic restoring force of the resilient member, when the one of the body and the catching member reaches a second predetermined position with respect to the other by being further moved in the first direction, the elastic restoring force acting in a second direction, characterized in that the supporting member and the connecting member are pivotally connected by a pivotal connection portion, and the pivotal connection portion is in the second path.
