An anchoring structure for an annular member includes a housing including a first casing and a second casing, and the annular member. The annular member is partially interposed between the first casing and the second casing. The annular member includes an external member that protrudes to an outside of the housing, and an internal member connected to the external member and located on an inside of the housing. The first casing includes a first engagement portion into which a first end of the internal member is inserted, the first engagement portion limiting the first end from moving in a direction away from the first casing. The first casing includes a second engagement portion limiting a second end of the internal member from moving in the direction away from the first casing while the first end of the internal member is engaged with the first engagement portion.

A keychain holder includes a body having a top end, a bottom end, a front face, and a rear face. The body has a through-opening extending therethrough from the front face to the rear face, such that the through-opening is sized to allow a keychain to be inserted therethrough. The bottom end is threaded to receive a vape battery.

A key ring comprises an elastomeric material. Specifically, the key ring comprises an outer coating of an elastomeric material, such as a silicone material such as, for example, polysiloxane, and an inner material of a relatively rigid material, such as metal, or other like material, for forming into a wound ring for holding keys, for example, and remaining in the wound ring formation. Alternatively, the key ring comprises no internal hard material and comprises an elastomeric material or a blend of an elastomeric material, such as silicone, thereby forming the key ring with the silicone material.

Disclosed is a generally planar automotive service tag, and method of using the same, having a first portion and a second portion. The first portion includes multiple foldable tags for describing service information, wherein each of multiple foldable tags fold and unfold along a foldable edge of the first end to indicate a status of a corresponding vehicle service. Each of the foldable tags has a male portion at a second end. The second portion of the automotive service tag includes an identifier for identifying the automotive service tag, and a plurality of female portions for each corresponding male portion of the plurality of foldable tags. The second portion further includes a protrusion that extends along an edge of a top end and a hanger portion that extends from the top end, the hanger portion being used to hang the automotive service tag on the rear-view mirror of a vehicle.

In a tracking device, a crescent-shaped printed circuit board partially encircles a battery to minimize thickness of the tracking device. A speaker and a light-emitting diode emit alerts upon command of a control apparatus or in response to a motion or temperature sensed by a sensor. A local network has one hub for tracking a plurality of tracking devices and a wider area network has multiple hubs for more detailed tracking of the plurality of tracking devices. The wide area network tracks the plurality of tracking devices anywhere and stores data of each tracking device including its last known position and its sensor data.

A press control key ring includes a split ring defining an opening between two opposite ends thereof, and a locking module including an inner casing for the insertion of the two opposite ends of the annular wire rod and having a mounting hole on the middle of the top wall thereof, an elastic member mounted in the inner casing with one end thereof secured to an inner bottom wall of the inner casing, a press block mounted in the mounting hole and supported on the opposite end of the elastic member, and an outer casing sleeved onto the inner casing and having an insertion hole on the middle of the top wall thereof for the insertion of the press block.

A dual key ring consisting of a ring holder, a first ring and a second ring is disclosed. The ring holder includes a connection tube with a ring hole transversely cut through one end thereof for securing the first ring, a movable block axially movably mounted in the connection tube with a round hole thereof for axial alignment with the ring hole, a locating block mounted in the connection tube, a first elastic member stopped between the movable block and the locating block, a movable cylinder coupled to the connection tube, steel balls rotatably mounted in ball holes around the movable cylinder and rotatably positioned in an inner annular groove in the connection tube, a connection rod mounted in the movable cylinder and stopped against the locating block, a connector coupled to the movable cylinder for securing the second ring and a second elastic member supported between the connection rod and the connector.
