A fastening device including a case unit, a spool, a driving unit, a knob and a connecting unit is provided. The case unit has a radial direction and an axial direction and includes an annular wall. The annular wall surrounds an inner space. The spool is within the inner space and includes an axial space including a large-diameter segment and a small-diameter segment, and the small-diameter segment is connected to the large-diameter segment along the axial direction. The driving unit is disposed above the spool along the axial direction, and the driving unit selectively prohibits the spool from rotating in a loosening direction. The knob is disposed above the driving unit along the axial direction, and the knob is coupled to the driving unit. The connecting unit is connected to the knob, and the connecting unit is disposed within the axial space and limited within the large-diameter segment.

A fastening device includes a case unit, a knob, an engaging unit and a spool. The case unit has an axial direction and includes a plurality of mounting teeth. The knob covers on the case unit along the axial direction. The engaging unit is coupled to the knob and includes an engaging portion. The spool is configured for a lace to wind therearound. The engaging unit is driven by the knob to switch between a first position and a second position along the axial direction. When the engaging unit is in the first position, the engaging unit prohibits the spool from releasing the lace. When the engaging unit is in the second position, the engaging portion is engaged with at least one of the mounting teeth, and the engaging unit does not prohibit the spool from releasing the lace. Therefore, the reliability can be improved.

This tool provides a means to manually rapidly rewind line onto a spool by serving as both an axle to spin the spool on, and a guide to keep the line positioned over the spool barrel while the spool is spun rapidly, taking up the line that has been payed out.

A rope adjustor and a wearable item. The rope adjustor includes a base, a rope reel, a first linkage portion is arranged on the rope reel; a rotation-stopping tray, the rotation-stopping tray is arranged on and connected to the base, and the rope reel is arranged inside the rotation-stopping tray, a first rotation-stopping portion is arranged on one side of the rotation-stopping tray away from the base; and a rotatable cover, the rotatable cover is arranged on and rotationally connected to the rotation-stopping tray, and the rotatable cover is insertably connected to the rope reel, and one side of the rotatable cover facing the rotation-stopping tray is provided with a second linkage portion and a second rotation-stopping portion, the first linkage portion is cooperated with the second linkage portion, and the first rotation-stopping portion is cooperated with the second rotation-stopping portion.

A rope dispensing apparatus for rapidly dispensing a continuous rope from a compressed rope cartridge. The apparatus includes a canister for storage of the rope cartridge, a resealable lid with an opening for passing the rope from the cartridge out of the canister through the lid, and a replaceable cutting mechanism for cutting the rope when a desired length has been dispensed. Preferably, the rope cartridge is shrink-wrapped to fit within the canister and keep the rope from unraveling while therein.

A retractable reel system includes a reel, a gear assembly, a paddle wheel and a spring. The reel includes a concentric wheel shaft where the reel and wheel shaft rotate to wind and unwind a length of material from the reel. The gear assembly engages with an end of the wheel shaft to provide a gear reduction ratio between the wheel shaft and an output shaft of the gear assembly. The paddle wheel is connected to and concentric with the output shaft, and the paddle wheel includes a paddle that extends beyond an outer edge of the paddle wheel that rotates with the paddle wheel. The spring is arranged outside the outer edge of the paddle wheel. The spring is compressed by the paddle to store an energy when the reel is rotated to unwind the length of material from the reel. The stored energy is used to rotate the reel to wind the length of material around the reel.

The present disclosure relates to a multifunctional retractable puller for pet, which includes a housing, a reel, a ribbon wound on the reel and a zinc alloy hook buckle, a handle integrated with the housing, a handle metal buckle, and a garbage bag device mounted on the metal buckle. The reel-locking key and the reel-opening key of the present disclosure form a switching group. The LED lamp has a function of warning and entertainment, which is convenient for users to warn others when crossing the road at night. The puller has the functions of charging the battery and being charged by the battery, so users do not need to replace the battery. The puller is equipped with a garbage bag device, from which the garbage bag can be taken out at any time, thus facilitating the users dispose of pet excrement at any time.

The invention relates to a winding device for an animal leash (1), in particular for a dog leash, comprising a housing (1) which houses the leash (3) and has a pull-out limiting device and a retaining ring (4) having an engagement opening (5), said retaining ring (4) having a pivot arm (4a) which is connected to the retaining ring (4) by means a pivot joint (6), closes the engagement opening (5) of the retaining ring (4) in its non-pivoted position and releases the engagement opening (5) of the retaining ring (4) in its pivoted position. In order to be able to use such a winding device in a simple manner to secure a dog in a motor vehicle in compliance with safety regulations, according to the invention, a lock tongue (11) is arranged at the pivot arm (4a) at its end facing away from the pivot joint (6) or at the retaining ring (4) at its end facing the pivot arm (4a), which tongue (11) can be inserted into a motor vehicle belt buckle when the retaining ring (4) is open.

A tether includes a housing defining a cord aperture, a spool located within the housing and configured to rotate about a spool axis in either an extending direction or a rewinding direction, a cord wound around the spool and configured to pass through the cord aperture, a biasing member coupled to the spool, and a retractor lock. The biasing member biases the spool to rotate in the rewinding direction to retract the cord into the housing. The retractor lock is movable between a locked position and an unlocked position. The retractor lock prevents rotation of the spool when in the locked position and allows rotation of the spool in the unlocked position. The retractor lock is moves from the locked position to the unlocked position in response to a threshold cord force on the cord.

A temporary horizontal lifeline device includes a main frame, a central shaft pivotally arranged on the main frame, a drum and an external gear affixed on the central shaft, a spanner adapted for driving the central shaft to rotate, and a cable member winded around the drum. A gear groove is arranged on the periphery of the external gear. A first spring is arranged on the main frame so as to provide a force to enable the drum to retrieve the cable member. The main frame also comprises a brake element and a detent provided thereon. The brake element has a first state for restrict the gear groove and a second state for releasing the gear groove, which prevents the external gear from rotating forward and backward when the external gear is in the first state. The detent has a first position to mesh the gear groove and a second position to release the gear groove, so that the external gear is only allowed to unidirectionally rotate in the first position. Accordingly, the present invention is convenient and safe to use when conducting retrieving operation, and effectively improves the stress concentration issue of conventional detents.
