PURPOSE:To prohibit turning-on of a switch unless a mixer cup is set, by providing a tapered part to the top edge of a switch button and a projection having the same taper in the bottom end part of a safety lever. CONSTITUTION:A tapered part 5 is formed to the top edge of a switch button 5, and a projection 7 having the same taper as the part 5 is provided in the bottom end part of a safety lever 6. When the bottom surface of a mixer cup 9 contacts the lever 6 and the lever 6 descends, the switch can be turned on, but when the cup 9 is not placed, the lever 6 is reset by a resetting spring 8 held to the rib 19 of a body 1, and the switch is turned off. Thus, the device is made safe. |
