When the desk lamp is put into use, the magnifier component is combined with the receptacle as a desk lamp. The whole assembly is convenient.

Abstract: A multi-mode tandem bicycle includes a frame, a steering wheel, a directional wheel, a first pedaling member, a second pedaling member, a first seat, a second seat, a first transmission unit, and a second transmission unit. By pivoting at least one of the first seat and the second seat on the frame, direction of the first seat or the second seat can be changed and fixed on the aforementioned frame, and at least one of the first seat and the second seat is pointed toward and connected with the steering wheel, thereby resulting in a variety of riding modes.

Abstract: A writing instrument is disclosed. More specifically, the writing instrument has a blowing function. The writing instrument comprises a penholder with the blowing function and a refill with a writing function. The penholder is composed of a first tube body with a hollow main body connected to a second tube body with a hollow main body. The first tube body is separated from or locked with the second tube body. The first tube body and the second tube body have air inlets and a plurality of scale holes respectively. Accordingly, the writing instrument does not only have the writing function, but also provides the blowing function for wind instruments. The entertainment of the writing instrument is then improved. The value added is also increased to have the economic efficiency.

Abstract: An aromatic container includes a first part which is provided with a first hollow part and a first assembly part; a second part which is provided with a second hollow part and a second assembly part; an assembly part which assembles the first part and the second part, which can be shifted relative to each other, into a closed space; an additive member which is fixed at the first part or the second part; and aromatics which are emplaced in the aforementioned closed space. The aromatic container can be worn on a human body with the additive member, and can be freely opened and closed by a relative shifting between the aforementioned first part and the second part.

Abstract: A tape dispenser includes a main seat and a movable member. The movable member is connected to the main seat and can move relatively to the main seat. A dragging member is located at an upper rim of the main seat and a first space is formed below the dragging member. A cutting edge is transversally located at a proper distance to the dragging member. The aforementioned dragging member is transversally crossed over at a proper height of the main seat, and a second space, which is not reaching to a bottom rim of the main seat, is formed from top to bottom, at two side rims of the main seat, between the dragging member and the cutting edge. Accordingly, the tape dispenser can be surrounding a tape roll for cutting the tape, and the preserved second space can facilitate pulling the tape.

Abstract: A simple adhesive tape cutter according to the invention includes a cutter seat, which has elastic and flexible fastening section and fastening member at lower side portions thereof and sawteeth at an edge of an upper surface thereof, thereby being quickly accommodated around an adhesive tape roll and readily cutting of adhesive tape.

Abstract: A multi-functional hand tool includes a base, an upper cover, a cam, a turning disk, a plurality of tool heads, and an indication unit. The base and the upper cover have a plurality of tracks, respectively. The turning disk is pivotally connected at a lower side of the base. In the tracks at the base and the upper cover are tool heads having distinct styles, and the tool heads are accommodated by springs.
