Hand held electrical mixing beater

Handheld electric beater-mixer adapted to drive selectively at least one so-called beating accessory (10) such as, for example, a whisk, or a so-called mixing accessory (25) turning at a high speed such as, for example, a mixer foot, comprising a body (2) containing an electric drive motor (6), two rotatable coupling devices (38, 16) connected to the shaft of the motor and adapted to receive, via respectively two engagement passages opening into the body, the beating accessory (10) and, respectively, a mixing accessory (25), and a control switch (52) for the electric motor which is actuated by an actuating finger piece (48) mounted rotatably on a rotation axle (50) so as to occupy a stopped position and several switched positions for continuous operation of the motor,

• characterized in that a spiral spring (66) is mounted concentrically to the rotational axle (50) of the actuating finger piece (48) and has a so-called fixed end (67) which is connected to said actuating finger piece (48) and a so-called free end (68), and in that it comprises moreover a safety member (70) having a portion forming an abutment (72) and movably mounted in the body (2) between a rest position in which the mixing accessory (25) is inserted in its coupling device (16) and in which the free end (68) of the spring (66) rests against the portion forming an abutment (72) of said safety member (70) so that the spring (66) will be continuously tensioned when the actuating finger piece (48) occupies each of its switched positions, such that the actuating finger piece (48) is held in its switched position by the hand of an operator against the force of the spring (66), and a retracted position to which it is brought by the insertion of the beating accessory (10) into its coupling device (38) and in which its portion forming an abutment (72) is removed relative to the free end (68) of the spring (66) such that the spring (66) will be continuously relaxed when the actuating finger piece (48) occupies each of its switched positions in which said finger piece (48) is held in place with the help of mechanical retention means (74) disposed in the body, said safety member (70) automatically returning to the rest position after withdrawal of the beating accessory (10).
