In addition, a device for lifting up the movable plate (22) is provided, comprising two levers (58) which bear on the fixed plate (14) and one end (62) of which is engaged with a pin (32) connected to the crank (26) while their free end (64) forms a control button which, when pushed down, causes the pin (32) to be raised.
