Abstract: An accommodating device for receiving a connector of a reel-type mouse includes a mouse body, a reel unit, and an accommodating portion. The mouse body includes an operating surface, a bottom surface, an accommodating space, and an opening. The accommodating space is between the operating surface and the bottom surface. The operating surface has at least one button body. The reel unit is in the accommodating space, and has a cable and a cable connector. The cable is movable via the opening for linear displacement motion. The cable connector is connected to an end of the cable, and is outside the accommodating space. The accommodating portion is disposed on the bottom surface. An appearance of the accommodating portion corresponds to that of the cable connector so as to receive the cable connector.

Abstract: A reel device of diversion joint comprises: a casing, a wire holder, a telegraph line, a position plate and two L-shape anchors. The casing has a shaft and a restraint cavity. The wire holder is located on the shaft. The telegraph line is winded inside the wire holder. The position plate located on the wire holder has a guiding groove and at least one anchor recess. Two L-shape anchors located on the guiding groove are separated to two sides of the shaft, and each of the L-shape anchors has a slider protrusion to slide along the guiding groove. When the joint performs a linear motion, the wire holder drives the shaft to rotate and the slider protrusion slides along the guiding groove. When the linear motion stops, the joint is fixed on a position where the slider protrusion is anchored in the anchor recess.

Abstract: A reel device of diversion joint comprises: a body, a reel-shaft part, a telegraph line, a conduct-surface body and two conduct-acting parts. The body has a shaft and a groove hole. The reel-shaft part is located on said shaft. The telegraph line has a joint at least one end, a part of said telegraph line is near by said reel-shaft part around. The conduct-surface body is located on said reel-shaft part, and has a conduct groove and at least one locating hole. Two conduct-acting parts are located on said groove hole and two sides of said shaft, has at least one conduct body on said conduct groove. When said joint used a liner motion, said reel-shaft part used said shaft to rotate; said joint is fixed on a position when said conduct body in said locating hole.
