ABSTRACT Electric household blender having a base enclosing a motor to drive the tools of an auxiliary unit such as a carved element, wherein the auxiliary unit is anchored by lock bars arranged thereon to bolts provided on the base. The bolts can be rotatably moved together with a ring mounted on the base for the purpose of locking, which ring, in turn, cooperates with an operating switch to turn the drive motor on and off and with a positioning member, lock rod and lock fork. The lock bars are either rigidly arranged on the auxiliary unit and formed in two pieces, or formed as one-piece, double- bent, flat pushers mounted in a movable manner in the housing of the auxiliary unit. The operating switch and the lock bars can only be activated when the lock bolts have first entered into the recesses or lock bar in such a manner that the auxiliary unit is nonremovably locked in place.
