Abstract: A juicer comprises a base, a column extending upward from the base, a vertical rod, a top seat, and a juicing device. The vertical rod has a portion movably mounted in the column and is movable along a vertical direction. The top seat is securely mounted to an upper end of the vertical rod and includes a compartment and an annular recessed portion surrounding the compartment. The juicing device comprises a pressing cup and a reamer. The pressing cup is mounted in the compartment of the top seat and includes a disc having a first side releasably engaged with the top seat and a second side for cooperating with the reamer for extracting juice from a citrus placed on the reamer. The disc has an annular end edge received in the annular recessed portion of the top seat.

Abstract: A heat dissipation fan has a casing, a stator fixedly received in the casing, a sleeve with a central hole securely attached to the stator, a lubricating bearing with lubrication oil contained therein mounted in the sleeve, a fan rotatably mounted in the casing and having a magnet mounted therein to be a rotor, a shaft extending from the fan and securely received in the lubricating bearing and a locking disk securely mounted on the shaft to lock the lubricating bearing on said shaft. The lubricating bearing has a central hole defined therein, a chamber defined in the bottom end of said bearing and at least one oil groove longitudinally defined in the outer periphery of said bearing. This can lubricate the shaft and guide the lubrication oil to avoid noise and oil from leaking from the sleeve and drying out the bearing. Consequently, the useful life of the heat dissipation fan will be increased.

Abstract: A support base is mounted to a golf bag of the type having a substantially U-shaped resilient defined by a mediate section and two limbs. The support base has two parallel side passages in a top side thereof. The support base further has a cutout in a lateral side thereof. The cutout and the side passages being communicated with each other and arranged to define a tongue with the side passages located on both sides of the tongue. Each side passage includes an open outer end and a closed inner end. An end wall defining the inner end of each side passage includes an inclined groove. The cutout includes an outer open end and an inner end that is aligned with the closed inner ends of the side passages.

Abstract: An adjustment mechanism mounted in a chair for releasably locking one chair component in one of positions relative to a seat. The mechanism comprises a tube-like brace secured to underside of seat; a sliding member slideable in brace secured to one chair component and having lengthwise recesses; a guide member coupled to sliding member; a hook member having a lower end coupled to guide member and an upper bent end; a first member secured in brace including a notched member having curved members and a channel; and a second member secured in brace together with first member for receiving sliding member and hook member, a spring-loaded detent of second member being secured in a hole and having a portion projected from hole into one recess for engagement in an unused state. One chair component is operative to push down to cause bent end to move through channel in response to a disengagement of detent from one recess and pull up to lock in one of curved members with detent engaged with the other recess.

Abstract: A kite has a cover sheet and a cross-shaped frame. The cover sheet has an oblong hole and four triangular corner bags. The cross-shaped frame has a spine, a two-way joint disposed on the spine, and two crosspieces connected to the two-way joint. Two rotating wheels are disposed on the spine. A plurality of rotating vanes engage with the rotating wheels. The spine is inserted in two of the triangular corner bags. Each of the crosspieces is inserted in the corresponding triangular corner bag. Two tail bands are connected to the cover sheet.

Abstract: A suit hanger includes a hook having a straight portion and a frame connected to the hook. The frame has an articulating section in a middle thereof, thereby allowing the frame to be folded at the articulating section along a pivotal axis that is at an angle with an extending direction of the straight portion of the hook.

Abstract: A feeding device receives various kinds of syringe needles and feeds them one by one into a press roller unit of a syringe needle shredder which pulls the needles, rolls the needles flat and then sends them down into a chopping roller unit to chop the flat needles into very small bits. The feeding device has a straight hole and a conical hole for different needles such as super short ones or special shaped ones to be fed down the needles maybe elastically clamped to securely move down to the press roller unit.

Abstract: A swayable backrest includes a backrest frame including two spaced vertical tubes each having a lower end attached to the seat of the chair. Each vertical tube further includes an upper end with a first hole. A hollow connecting beam is connected between the upper ends of the two vertical tubes and includes two transverse slots. An attaching member includes two ends each having a second hole. Each end of the attaching member is extended through an associated transverse slot. The attaching member is attached to a backrest of the chair to move therewith. A pivotal tube extends through the first hole of each said vertical tube, the second hole of each end of the attaching member, and the hollow connecting beam, thereby allowing pivotal movement of the attaching member relative to the backrest frame.

Abstract: A door lock includes a main body including a transmission assembly and a positioning assembly. The positioning assembly includes an inside seat and an outside seat. An inside rose liner is mounted around the inside seat and includes two positioning holes. An inside rose is mounted around the inside rose liner. An anti-torque ring is mounted around the outside seat and includes two lugs formed thereon. Two positioning posts respectively project from the lugs and extend along a longitudinal direction of the anti-torque ring. An outside rose liner includes an inner threading that is engaged with an outer threading of the outside seat. The outside rose liner includes a side with an annular recessed portion for receiving the anti-torque ring. The annular recessed portion includes two recess extensions for positioning the lugs of the anti-torque ring. An outside rose is securely mounted around the outside rose liner to rotate move therewith.

Abstract: A ring assembly for a pen has a bottom ring, a top ring, and a slender bridge connecting the bottom ring and the top ring. In assembly, a barrel of the pen extends through the bottom ring and the top ring, so that a sticker adhered around the barrel is securely attached to the barrel by clamping of the top ring and the bottom ring. Furthermore, a gap formed by two conjunct sides of the sticker is concealed by the bridge. By such arrangement, the ring assembly is able to be decorative and to avoid peeling of the sticker from the barrel after long-term use.
