A pressing unit(120) includes a housing(121) having a cavity, a pin(122), and a coil spring(124). The housing is moved in a vertical direction. A lower part of the housing is opened. The pin penetrates the housing. The pin is moved vertically along the cavity of the housing. The pin comes in contact with an object. The coil spring is installed in the cavity of the housing in order to surround the pin. The coil spring is pressed according to a falling state of the housing in order to apply a load to the object. The load for pressing the object is applied to the pin.
