A data cable device comprises a base, a retracting assembly, a data cable, and a release control assembly. The retracting assembly comprises a winding frame and a driving structure. The winding frame is in rotating connection with the base. The driving structure is connected to the winding frame and is configured to drive the winding frame to rotate relative to the base. The data cable is wound around the winding frame. The release control assembly is in electric connection with the data cable, and is configured to generate a control signal based on an interface of the data cable not being connected to an external device, and cause the driving structure to drive the winding frame to rotate relative to the base based on the control signal.

Disclosed are a wire winding system and a data cable device. The wire winding system comprises a base, a winding assembly, a locking assembly, and a reset member. A first bearing surface of the base comprises one of a ring-shaped guide groove and a rolling groove. The winding assembly comprises a rotary shaft and a bracket. The locking assembly comprises a swing member and a rolling member. A surface of the swing member facing the first bearing surface comprises the other of the ring-shaped guide groove and the rolling groove. The ring-shaped guide groove comprises a locking point recess. The rolling member is embedded in the rolling groove and the ring-shaped guide groove.

A light roller device is disclosed herein. The light roller device includes a support frame member; and a roller assembly coupled to the support frame member, the roller assembly including a roller member that is rotatable about a portion of the support frame member, the roller member configured to guide and/or support a wiring portion of a light strand as the light strand is being hung from an elevated object, and the roller member being inwardly tapered toward a middle portion of the roller member for guiding the wiring portion of the light strand to the middle portion of the roller member as the light strand is being hung from the elevated object.

An oxygen tube apparatus for transporting a length of oxygen tubing and facilitating mobility of a user includes a platform. A pair of wheels is rotatably coupled to the platform. A handle is coupled to the platform. The handle extends upwardly from the platform to facilitate a user in moving the platform. A reel casing with an interior space is coupled to the handle. A reel is positioned within the interior space. A tube is coiled around the reel. The tube is fluidly couplable to an oxygen source. The tube is outwardly extendable from the reel casing through an aperture. An adaptor port coupled to the reel casing is aligned with the reel to fluidly couple an oxygen hose to the tube and to transfer oxygen from the oxygen source to the reel casing to facilitate a user in receiving oxygen from the oxygen source.
