Abstract: The present disclosure discloses a connector. The connecter includes a housing; a pipe at least partially disposed in the housing; and a base mounted to a first item and disposed to the housing to allow the housing to float between a first longitudinal position and a second longitudinal position relative to the base, such that the pipe is connected to a second item in a floating manner along the longitudinal direction.

Abstract: The present application discloses a connector, which is mounted to a first object and connected between an outlet device and an inlet device to direct a fluid. The connector comprises: a housing mounted to the first object; a pipeline penetrating the housing in a flow direction of the fluid and comprising an outlet end connected to the outlet device and an inlet end connected to the inlet device; a floating device disposed on the housing and floatingly connected to the pipeline, allowing the pipeline to float in the radial direction transverse to a flow direction of the fluid with respect to the housing. The present application also discloses a connecting system.

Abstract: The present application discloses a locking device including: a mounting seat; a locking member, rotatable around an axial direction and movable in the axial direction, when the locking member is in a first axial position and a first rotational position, the locking member is retracted into the mounting seat along the axial direction, and the mounting seat prevents the locking member from rotating around the axial direction; and when the locking member is in a second axial position and a second rotational position, at least a portion of the locking member extends in the axial direction from the mounting seat, to be inserted into and engaged with a second object, and the mounting seat prevents the locking member from moving in the axial direction; and a compression torsional spring biasing the locking member toward the first axial position and the second rotational position.

Abstract: A latch for releasably locking a first object to a second object is disclosed.
