An accessory to a mobile device which secures a stylus to the device or device case such that the stylus is extractable for use, and retractable for storage. They stylus being attached to the accessory by a retractable cord so that it may not be separated from the device or misplaced. The accessory further includes a stand to support the mobile device at a convenient angle to allow use with the stylus.

In order to improve assembling convenience and productivity of products, the present invention provides a wire winding adjusting device comprising a reel portion which is accommodated in a housing unit and is selectively hook-engaged with and rotated interlocking with a rotation manipulation means such that a wire is wound on the outer circumference thereof, wherein the rotation manipulation means is rotated about a driving protrusion at the center thereof during a rotation manipulation. The reel portion comprises: a winding body unit which has a cylindrical shape, has an accommodation groove formed in an upper surface side thereof such that an end portion of the driving protrusion is accommodated in the accommodation groove and a lower surface side which is dented to form a coupling groove portion, and includes a wire tying unit adjacent to the bottom surface of the coupling groove unit and having a first tying hole and a second tying hole through which the wire partially passes and which are formed through the wire tying unit to be apart from each other such that the wire is tied; and a pair of flange portions which expand and protrude outward in the radial direction along upper and lower boundaries of the outer circumferential surface of the winding body unit such that a wire winding groove can be formed between inner surfaces thereof facing each other, and which have a through-slot groove that is open because the first tying hole and the second tying hole are apart from each other along the circumferential direction such that an end portion of the wire pulled into the coupling groove unit can be pressed by a part of the wire.

The present disclosure discloses an operation switch, including a housing, an end cap, a slider, a sliding pin and a positioning pin. The housing has a housing opening on one side of the housing away from the end cap. The slider has a slider stop plate extending out from the housing opening. The end cap has a guide sliding chute. The sliding pin is in clearance fit with the guide sliding chute. The guide sliding chute has a lower positioning recess and an upper positioning recess. The end cap has a guide ramp below the guide sliding chute, and an end of the positioning pin slidably contacts or touches the guide ramp. The present disclosure also discloses a pull-out control mechanism, including a housing; a hose/cord clamping wheel set including a first rotating wheel and a second rotating wheel, both mounted in the housing; and a locking and releasing mechanism.

A hose reel apparatus has a frame and a drum rotatably attached on the frame for receiving a hose wound thereon. A drive system and brake assembly are attached on the frame operatively engaged with the drum. An indexer is slidably mounted on a guide rail on the frame having a channel for receiving the hose and adjacent clamp arms which are selectively operable to clamp the hose.

A fastening device includes a case unit, a spool, a connecting unit, a knob and an engaging unit. The case unit includes a wall forming a receiving space, a partition separates the receiving space into an upper chamber and a lower chamber, a through hole located at the partition, and a base detachably connected to at least one part of the wall. The spool is located at the lower chamber. The knob is connected to the connecting unit. The engaging unit is located at the upper chamber. After the connecting unit is inserted into the spool, the through hole and the engaging unit to couple to the knob, the partition, the spool, the connecting unit, the knob and the engaging unit are connected integrally without being separated from each other while the base is separated from the at least one part of the wall.

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.

The present invention discloses an electronic device for retracting, releasing, and storing cables or cable-like structures for equipment, devices, apparatus, machines, or similar structures. The device provides an effective way to release, retract, and store cables and cable-like structures. By retracting the cable into the device and routing it around an inner cylindrical structure using motors, the device can efficiently control the length of cables as required. The motor(s) can release the cable to any desired size, so organizing and making it the desired and appropriate length is very convenient. Supporting structure, gears, and bearings assure cable and cable-like structure to retract and release. The line-linked switch or remote switch provides convenience when using the device.
