• an electric motor mounted on the base, the electric motor mobile in rotation around a main axis and configured to drive the tool;
• and
• a locking system of the removable cover on the base,
• wherein the locking system comprises:
• an actuation device;
• a first lever arranged inside the base, the first lever mobile in rotation relative to the base around a first lever axis, the first lever configured to be driven in rotation around the first lever axis by the actuation device;
• and
• a first hook configured to be set in motion by the first lever, the first hook comprising:
• a lower end attached to the first lever so as to be mobile in rotation relative to the first lever around a second lever axis parallel to the first lever axis;
• an upper end;
• and
• an elongated central portion connecting the lower end to the upper end,
• wherein the elongated central portion of the first hook extends through a first opening of the base, the elongated central portion of the first hook being guided by the first opening of the base, so that the first hook is configured to:
• slide relative to the base along its central portion between a locking position and an unlocking position;
• and
• jointly pivot relative to the base around a first pivot axis parallel to the first lever axis and passing through the first opening of the base between a locking orientation and an unlocking orientation, and
• wherein the culinary preparation appliance is configured to operate by the actuation device driving in rotation the first lever around the first lever axis between:
• a locked configuration, wherein the first hook is in its locking position and in its locking orientation and wherein the upper end of the first hook is in contact with the removable cover, preventing removal of the removable cover;
• and
• an unlocked configuration, wherein the first hook is in its unlocking position and in its unlocking orientation and wherein the upper end of the first hook is spaced from the removable cover, allowing removal of the removable cover.
