Abstract: An extension cord with environmental condition sensing ability has a plug for connecting to a power source, and includes a main body, a sensor unit, and a current control unit. On the main body, there are provided a first socket group and a second socket group, which are electrically connected to the power source via the plug. The sensor unit is electrically connected to the second socket group for sensing an environmental condition and thereby generating a signal. The current control unit and the sensor unit together form an electric circuit, and the current control unit receives the signal generated by the sensor unit and turns on or cuts off electric current being supplied to the second socket group according to the received signal.

Abstract: This present invention discloses a desk lamp with a separable magnifier, which comprises a magnifier component and a desk lamp holder. Around the lens of the magnifier component, a plurality of illumination lamps is arranged for illumination. When the power storage module of the magnifier is exhausted, the handle of the magnifier can be inserted into the slot of the receptacle to charge. 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. A cam is additionally provided between the base and the upper cover. By rotating the turning disk, the cam is driven to push the tool heads and compress the springs, thereby stretching the distinct tool heads out of the tracks for further usage.

Abstract: A simple adhesive tape cutter and marker of the present invention implements the marker on an adhesive tape roll, and is primarily configured to comprise the marker affixed to a side edge of a reel of the adhesive tape roll. Length of the marker is such to enable encircling any position around a largest periphery of the adhesive tape, and a cutting member is configured on the marker. The cutting portion of the marker is employed to cut the adhesive tape; moreover the marker can be placed below a cutting position of the adhesive tape, the adhesive tape covering the marker thereat. Thus, next time the adhesive tape is to be cut, the marker directly indicates a draw-end of the adhesive tape, and thereby realizes easy lifting up of the draw-end.

Abstract: A light and portable adhesive tape cutter according to the invention includes a gathering section having elasticity. Two ends of the gathering section are respectively devised with a fixed cutter seat and a sliding cutter seat each having a sawtooth. The gathering section is appropriately wrapped by an adhesive tape roll. The sliding cutter seat is capable of sliding movements to become mounted on the fixed cutter seat to altogether cut off the adhesive tape in a quick and convenient manner. The adhesive tape cutter may also be a simplified cutter seat as a formed integral that can be rapidly wrapped by an adhesive tape roll for quickly cutting off an adhesive tape.
