A data cable and an electronic device are disclosed. The data cable may comprise: a shell, a turntable, and a wire harness wound on the turntable and configured to drive the turntable to rotate in a first direction. The data cable may comprise a switch and an elastic device connected to the shell and the turntable. The elastic device may be configured to drive the turntable to rotate in a second direction opposite to the first direction. The switch may be configured to lock the turntable in response to release of the wire harness after being extracted from a first position that the wire harness is completely wound on the turntable, and unlock the turntable to rotate in the second direction in response to release of the wire harness after being extracted from a second position that the wire harness is partially wound on the turntable.

An organization system may include a slotted housing comprising a top notch. An organization system may include a cartridge configured to receive a spooled elongated profile object, and configured to be received by a slot of the slotted housing, wherein, the top notch is defined by a housing wall, wherein the slot and the housing wall form a soaking bath for the cartridge and the spooled elongated profile object therein; and wherein, when the spooled elongated profile object is unspooled from the cartridge, the top notch limits the cartridge from rocking or rotating within the slot.

A roller apparatus (102) is provided including roller means (104), drive means (110) for driving rotation of the roller means in use, and an electrical power source for providing electrical power to the drive means in use. The electrical power source is provided by one or more batteries (112) located internally of the roller means.

A fish tape tool includes a housing including a base and a cover. The housing defines a chamber between the base and the cover. The base defines an exit opening and a channel extending from the chamber to the exit opening. The fish tape tool also includes a drum configured to be inserted into the chamber of the housing, the drum containing a fish tape. The drum is configured to be manually rotatable relative to the housing to dispense or retract the fish tape from the housing via the channel and the exit opening. The cover defines a central aperture that is aligned with a central bore of the drum.

Provided are a fiber-coiling device and a communication device assembly having the same. The fiber-coiling device includes a supporting member (1) provided with a slideway (11), and at least two fiber-coiling members (2); the fiber-coiling member (2) includes a fiber-coiling column (21) and a sliding block (22) connected to each other; and the fiber-coiling column (21) is used for an optical fiber to coil around, and the sliding block (22) is capable of sliding along the slideway (11) and being positioned at any position of the slideway (11).

A device for covering a surface includes a cover (9), a drum mounted to rotate and able to wind or unwind the cover, and a translation system. The translation system includes a pair of closing spools (11r) mounted to rotate about a closing shaft (12) and each coupled to a closing cord (1c) to move the drum on rails (6) in a closing sense (Dc), and an axle shaft (12) coupled to the drum (2t) the rotation of which enables winding of the cover onto the drum (2t) and to move the cover on the rails in an opening sense (Do). A motor (M) connected to a driving shaft (10M) and coupled to a clutch system is configured to enable the driving shaft to actuate alternately rotation of the closing shaft (11) and the axle shaft (12).

A system for managing charging, the charging management system is provided. The system comprises a charging cord management device, a charging cord connector, a device, a first charging cord, and a second charging cord. The charging cord management device is configured with the second charging cord. The charging cord management device is configured to control the second charging cord and the charging cord connector in a direction of the earth gravitational field from a first altitude to a second altitude without user interaction and wherein the first altitude is different from the second altitude. The charging cord connector is configured to be in contact with an apparatus with a height above ground level.

A hose and reel system that includes a reel assembly that is rotatably mounted within a housing. The reel assembly includes an accumulator drum having an inner chamber and the drum is coupled at opposite ends to disc elements. The housing can include a hose guide element for guiding a hose that is spooled about the outer surface of the drum and, if desired, a pair of mandible elements.

An apparatus and method for winding a cable is disclosed. The apparatus includes a first plate and a second plate that engage via oblong slots at a central axis to form a cable winder system. Each of the first plate and the second plate have a handle used to rotate the cable winder system to collect wound cable on the cable winder system.

The present disclosure relates to a position-adjustable spool return-stop device, including a first sleeve, a second sleeve, and a wire saddle, wherein the wire saddle has a cylindrical front end and a cone-shaped rear end; a through hole, through which a wire body can pass, is reserved in a middle of the wire saddle; a plurality of grooves are provided at the rear end of the wire saddle, which divide the rear end of the wire saddle into multiple petal bodies; the first sleeve and the second sleeve are sequentially sleeved outside the wire saddle from front to back, and the second sleeve is internally provided with a bundling hole; the inner diameter of the bundling hole gradually increases from front to back, and the wire saddle can move forward and backward along the bundling hole; and the wire saddle cannot rotate relative to the second sleeve.
