Abstract: The pen cap comprises a cap unit and an adhering unit formed on the cap unit. The cap unit comprises a top wall, a side wall, a bottom wall, and a groove. The top wall, the side wall, and the bottom wall are integrated and the side wall is located between the top wall and the bottom wall. The groove is inwardly formed on the top wall. A front end of a pen is inserted in to the groove. The pen cap can attach to a surface for insertion of the pen and make the pen stand on the surface to reduce the surface area occupied by the pen. With the adhering unit, the pen cap can firmly attach to a vertical surface or a horizontal surface to prevent the pen from rolling or sliding to ground and from being broken or lost.

Abstract: A belt has a band and a belt buckle. An end of the band has multiple hole sets formed thereon. The belt buckle is mounted on another end of the band and has a frame and a buckling element. An end of the buckling element is formed as at least one pivot bar pivotally connected to the frame. Another end of the buckling element is formed as multiple prongs selectively mounted through engaging holes of one of the hole sets. Thus, the buckling element and the band can be stably connected with each other. The prongs of the buckling element do not rub against edges around the engaging holes, so the engaging holes are not enlarged. Moreover, the prongs can be integrally formed on the buckling element. No additional manufacturing process is needed. Accordingly, the belt and the belt buckle are practical and convenient for manufacturing.

Abstract: A stick umbrella structure includes a main shank, a plurality of rib units and a canopy. A fixed hub and a movable slider are mounted on opposite ends of the main shank. The movable slider is slidably provided on the main shank and positioned at two predetermined positions. The rib unit consists of a main rib and a spreader rib. One end of the main rib pivot-connects with the movable slider. One end of the spreader rib pivot-connects with the fixed hub while the other end pivot-connects with a pivot point of the main rib. A center of the canopy is fixed to the fixed hub while an outer periphery of the canopy is fixed to the main ribs. Accordingly, the rib units are capable of unfolding the canopy by spreading the main ribs and the canopy can be folded in a reverse direction by retracting the main ribs.

Abstract: A liquid level alarm is placed in a tank having a bottom and has a weight, a floating box, an alarm circuit and a cord. The weight is placed on the bottom of the tank. The floating box has a top recess, a passage, a slide and a top cover. The passage communicates with the top recess. The slide is mounted slidably in the passage. The alarm circuit is mounted in the top recess in the floating box and has two contacts, an alarm element, a switch and a spring. The switch is connected to the slide. The spring is connected to the top cover and holds the switch open. The cord is connected to the weight and the slide. When the floating box moves above a predetermined level, the switch with the slide moves down and makes contact with the contacts to activate the alarm element.

Abstract: A clip for sheet-like articles includes a first clipping section on a first end thereof, a second clipping section on a second end thereof, and a flexible bend between the first clipping section and the second clipping section. The first clipping section and the second clipping section cross and overlap each other at an intersection. When in use, the flexible bend holds an end edge of a plurality of stacked sheets, with the first clipping section and the second clipping section respectively clipping two opposite sides of the stacked sheets, thereby maintaining the stacked sheets in the stacked state.

Abstract: A weight scale with hybrid graduation includes an elastic element, a carrier mounted to the lower end of the elastic element, an indicator block mounted between the elastic element and the carrier, and a graduated housing for receiving the elastic element and the indicator block. The indicator block includes at least one auxiliary graduation. The graduated housing includes at least one primary graduation having a unit different from that of the auxiliary graduation. A weight of an object attached to the carrier is measured through vertical relative movement between the primary graduation and the auxiliary graduation to provide more accurate measuring result.

Abstract: A bottle opener includes a first member and a second member. The first member includes an engaging section. The second member comprises a cap-removal portion and a grip portion. One of the first member and the second member includes two slots defined therein. An axle is slidably extended through the slots for pivotally connecting the first member and the second member. The engaging section engages with a portion of a circumferential end edge of a cap of a bottle to be opened. The grip portion of the second member is movable relative to the cap to a position for engaging with another portion of the circumferential end edge of the cap opposite to the portion of the circumferential end edge of the cap, thereby allowing removal of the cap.
