Abstract: A buckle device includes a main body, a rotational retaining device rotatably mounted to the main body, and a buckle having an end connected to the rotational retaining device to pivot therewith. The rotational retaining device includes a slit through which a free end of a strap is extended. A retaining member is mounted to the other end of the buckle and has an engaging portion for releasably engaging with an engaging section of the main body. The retaining member further includes an operative portion that is operable to disengage the engaging portion of the retaining member from the engaging section of the main body. The operative portion of the retaining member is located away from the free end of the strap when the buckle is in a retained position, thereby preventing inadvertent actuation of the operative portion of the retaining member.

Abstract: An easy chair device has a leg frame, and a chair main body disposed on the leg frame. Two backrest support rods and two armrest support rods extend upward from the leg frame. The chair main body has a backrest, a seat, and two armrests. The armrests are supported by the armrest support rods and the backrest support rods. A back band is disposed on a back of the backrest. Two fasteners are disposed on two ends of the back band. Two fastening bands are disposed on the armrests to engage with the back band.

Abstract: A stand to support an object has a bottom frame and two side frames. The side frames are each pivotally attached to opposite ends of the bottom frame with a pair of pivot pins. The pairs of pivot pins are located at different heights. A clasp is mounted on each side frame to detachably engage the bottom frame. When the clasps are released from the bottom frame, the side frames can be pivoted relative to the bottom frame. The stand is foldable. Because the side frames are respectively pivotally attached to the bottom frame by pairs of pivot pins at different heights, one of the side frames can overlap the other side frame. The size of the stand is reduced. Transporting and storing the stand become more convenient.

Abstract: A hanger assembly includes a vertical post, at least two fixing devices securely mounted to the vertical post at different levels, and at least two hanger members each of which is securely attached to an associated fixing device for supporting at least one object. The fixing devices are slidable along a vertical direction, thereby allowing adjustment in the levels of the fixing devices relative to the vertical post.

Abstract: The present invention relates to a grease gun having an automatic continuous feeding device, including a gun body, a piston chamber, a piston, a spring, a barrel chamber, a plunger, a container, a switch valve, and a trigger. Thus, the piston may be moved reciprocally and automatically by pressing the trigger successively, so that the grease in the container may be ejected outward continuously without having to compress and loosen the trigger repeatedly, thereby facilitating the user operating the grease gun.

Abstract: A massage device has a base casing, a cover casing engaging with the base casing, a driving mechanism disposed in the base casing, at least a rotating disk, and at least a massage ball set. The driving mechanism has a motor and at least a gear disk driven by the motor. A shaft is disposed on the gear disk. The massage ball set has a main rod, a three-way frame disposed on the main rod, and three rolling balls disposed on the three-way frame. The shaft is driven by the gear disk. The rotating disk is driven by the shaft. The massage ball set is driven by the rotating disk.

Abstract: A screwdriver includes a handle including a seat, a shank having a first end in universal joint with the seat and a second end engaged with a tool bit, and an elastic element for retaining the first end of the shank and the seat together such that the first end of the shank and the seat rotate together when the handle is turned. The first end of the shank is in the form of a ball. The seat includes a pinhole, the ball of the shank includes a pinhole, and a pin is extended through the pinhole of the seat and the pinhole of the shank. An inner periphery of the ball presses against an inner periphery of the seat.

Abstract: A backrest adjustment device has a hollow base seat, an oblong panel, a guide mount, a slide seat, a nut, a coiled spring, a compression spring, a positioning plate, a top panel, a screw rod, and a control rod. The positioning plate has a threaded aperture. The guide mount is disposed on the oblong panel. The guide mount has a bottom recess and an oblong hole. The positioning plate is inserted in the bottom recess of the oblong panel. The slide seat has a bottom groove, a slant slot, and a lateral lug. The screw rod has a disk head. The top panel has a plurality of click serrations. The top panel engages with the hollow base seat. The control rod has an oval plate, an extension bar, and a plurality of annular grooves. The screw rod passes through the compression spring, the lateral lug, the coiled spring, the nut, and the oval plate. The extension bar is disposed between the top panel and the hollow base seat.
