Abstract: A gravity switch structure includes a mount having a tube and an installation plate, a terminal assembly, and a slider having a column provided at the bottom end thereof with a press head. The tube has a column hole, in which the column is disposed, and a bottom having a through hole and a stopping portion where the bottom end of the column is abutted. The terminal assembly is disposed on the installation plate, having first and second electrically conductive members extending below the through hole. The column is movable axially, enabling the press head to pass through the through hole to be abutted against the second electrically conductive member to bend it elastically to contact the first electrically conductive member. The gravity switch structure is easily assembled, highly adaptable, and the stopping portion prevents the slider from directly impacting the second electrically conductive member.

Abstract: An electric can opener includes a bottom shell having an elongated slot, a rotatable shaft reciprocally moveable along the elongated slot, a main gear coaxially mounted to the rotatable shaft, a roller rotatably disposed inside the bottom shell, an engaging gear fixed to the rotatable shaft and located outside the bottom shell, a blade assembly disposed to the bottom shell, and an elastic member for imparting a return force on the rotatable shaft. The main gear has a bottom surface monolithically formed with a cam having a contact surface, with which the roller is rotatably contacted. When the rotatable shaft stays at a ready position, the engaging gear is away from the blade assembly, and when the rotatable shaft stays at an operating position, the engaging gear is close to the blade assembly for clamping a can between a blade edge and the engaging gear.

Abstract: An electric grinding device includes an outer barrel, an inner shell disposed in the outer barrel and provided therein with a battery and a motor, two guiding channels formed between the outer barrel and the inner shell, a hopper located below the two guiding channels and communicating with the two guiding channels, and a grinding sleeve and a grinding head disposed in the grinding sleeve, which are located below the hopper. A grinding gap communicating with the hopper is formed between the grinding head and the grinding sleeve. The two guiding channels enable the material to be ground to enter the hopper through anyone of the guiding channels smoothly and then enter the grinding gap to be ground into small particles.

Abstract: An electric frothing device includes a driving unit, a connecting rod, and a frothing unit. The driving unit has a housing, and a drive motor disposed in the housing. The drive motor has a power outputting shaft. The connecting rod is fixed to the power outputting shaft of the drive motor. The frothing unit has a fan fixed to the connecting rod and having blades, and a coil spring disposed with an interval from the blades of the fan.

Abstract: An electric driving scissors provide a high torsion force. The electric driving scissors includes a casing, a motor, a driving disk, a crank, and a cutting unit with a pair of knives. The driving disk, crank and knives of the cutting unit are connected pivotally and eccentrically. The motor is installed with a speed change means so that the rotation speed of the motor can be reduced to a lower speed in the rotary shaft with a higher torsion force. Thereby, a hard object can be cut. Furthermore, by the eccentric hole of the driving disk, the axial hole and pivotal hole at two ends of the crank, the rotary shaft of the motor can rotate, while the crank move linearly. Thereby, the angle of the movable knife of the cutting unit is changeable.
