Abstract: A weight training machine according to the present invention is a machine for conducting a dead lift or a bent over row while selecting and increasing/decreasing the weight, the machine comprising: a pair of body units, on which weight plates are stacked in the upward/downward direction, and which are provided on both sides of an operating unit, respectively; an operating unit, which is provided between the pair of body units, and which can move in the upward/downward direction; and a cable pulley unit for connecting the body units and the operating unit to each other such that, as the operating unit is moved in the upward/downward direction, the weight plates can be moved in the upward/downward direction, wherein, as the user operates the operating unit in the upward/downward direction and thereby moves the cable of the pair of cable pulley units, the user accordingly moves the weight plates on the body units, which are connected to the cable, thereby conducting weight training.

Abstract: Provided is a portable sewing machine. The portable sewing machine has an upper thread part and a lower thread part inside of the sewing machine and an interior structure simplified by defining the inside space of the sewing machine into a sewing needle part, a lever part, a motor part, a power supply part and a pulley part so as to reduce parts, size or weight. The portable sewing machine can be convenient to carry around and to be used without any limitation of places, and adsorption plates (see explanation of terms) are provided to the bottom surface of the sewing machine such that sewing work can be performed at any place where the sewing machine can be attached by means of the adsorption plates.

Abstract: The present invention relates to a portable multi-sewing machine having an interior structure simplified by defining the inside space of the sewing machine into a sewing needle part, a lever part, a motor part, a power supply part and the like so as to reduce parts, size or weight due to additional spaces provided for using an upper thread and a lower thread to the inside of the sewing machine, such that the single sewing machine can be convenient to carry around and to be used without any limitation of places, and adsorption plates (see explanation of terms) provided to the bottom surface of the sewing machine such that sewing work can be performed at any place where the sewing machine can be attached by means of the adsorption plates.
