Abstract: An assembling structure for timely and securely locking and releasing a rope includes a housing including two integral side walls for defining a space to allow a rope to pass through; a contact surface on an inner surface of the housing; a pivotal cam including an occlusion section and an engagement surface adapted to pivot about the contact surface from a first position to a second position and vice versa; a torsion spring on one pivot of the cam and having one end fastened in the cam and the other end passing through a limit member of the cam; and a pivotal trigger adapted to pivot about the housing from a third position to a fourth position and vice versa, the trigger including an occlusion member at one end in gear engagement with the occlusion section and a lever at the other end and extending out of the housing.

Abstract: An apparatus for timely and securely locking and releasing a rope includes a housing having an interior space and a communication portion for entering a rope into the housing. The housing includes an abutment portion fixed into the housing, a rotatable cam configured to be corresponsive to the abutment portion and pivotally connected to an inner side of one of the side panels, an elastic member installed between the side panel and the cam, and a rotatable start portion having an engagement surface and a first engagement portion. The rotatable start portion is configured to be corresponsive to an end of the cam and pivotally connected to an end of an inner side of one of the side panels, and an end of the start portion has a second engagement portion corresponding to the first engagement portion.
