1. A cutter set mounting structure of a food processor, comprising:
a container bottom, wherein the container bottom is provided with a mounting hole;
a cutter holder, mounted at the mounting hole for mounting a cutter of the food processor; and
wherein the cutter holder is provided with an anti-disengagement part, the container bottom is provided with an anti-disengagement matching part, and the anti-disengagement matching part matches with the anti-disengagement part to limit the cutter holder from falling out of the mounting hole under gravitational force;
wherein the container bottom comprises:
a base provided with the mounting hole; and
a locking component, mounted on the base and matching with the cutter holder and adapted to reciprocate relative to the base between a cutter removing position and a cutter locking position, and to lock the cutter holder to fix the cutter holder when moving to the cutter locking position, and to unlock the cutter holder when moving to the cutter removing position;
a locking and matching mechanism provided on the base and matches with the locking component for positioning the locking component in the cutter removing position to limit a movement of the locking component relative to the container bottom;
wherein the base and/or the locking component are provided with the anti-disengagement matching part;
wherein the cutter set mounting structure further comprises a restraining mechanism provided on the base and matching with the locking component for locking the locking component in the cutter locking position to limit a movement of the locking component to the cutter removing position;
wherein the restraining mechanism comprises a restraining member provided on the base and adapted to reciprocate relative to the base to lock the locking component in the cutter locking position or unlock a locking of the locking component, and a restoring member matched with the restraining member and configured for driving the restraining member to restore previous position;
during movement of the locking component to a cutter locking position, the restraining member is driven by the locking component to move to a position away from the locking component to ensure that the locking component moves smoothly to the cutter locking position; and in this process, the restoring member is elastically deformed to store elastic potential energy, and when the locking component moves to the cutter locking position, the restraining member is no longer limited by the locking component, and is automatically restored under restore elastic force of the restoring member, and locking the locking component in the cutter locking position;
when the locking component moves from cutter locking position to cutter removing position, the restraining member is moved against the elastic force of the restoring member, the locking of the locking component is released to ensure that the locking component smoothly moves to the cutter removing position;
wherein the locking and matching mechanism comprises an elastic member matching with the locking component, elastically deforming during a movement of the locking component relative to the base, and providing at least a part of a driving force to urge the locking component to the cutter removing position during restore deformation.
