In the present embodiment, the inner wall of the rotary member 3 has the convex portions 331 and the concave portions 332 alternately arranged in the circumferential direction, the convex portions 331 and the concave portions 332 being for partitioning the rotation speed. The main body seat 1 is provided with an elastic strip 71 and a limiting structure 72, wherein a middle section 711 of the elastic strip 71 is bent, elastic side sections 711 on two sides are symmetrically arranged, the elastic side sections 711 are supported on the limiting structure 72, the elastic side sections 712 are provided with elastic compression parts 71c, the elastic middle section 711 is extruded by the convex parts 331 when the rotating part 3 rotates, the elastic compression parts 71c are pressed, bent and deformed at the moment, the elastic middle section 711 is gradually clamped out of the concave parts 332, the rotating part 3 rotates, the compression amount of the elastic compression parts 71c is gradually increased until the elastic middle section 711 is completely clamped out of the concave parts 332, and the elastic compression parts 71c are in a maximum compression state at the moment; thereafter, the rotation member 3 continues to rotate, and the elastic middle section 711 is again engaged with the concave portion 332 by the elastic force of the elastic compression portion 71c, so that the engagement and disengagement of the concave portion 332 of the elastic middle section 711 is alternately performed with the rotation of the rotation member 3.

When the elastic middle section 711 is clamped in a certain concave portion 332, corresponding to a certain rotation gear, when a user rotates to rotate the operation member 2 around the central axis, the extrusion force generated when the convex portion 331 extrudes the elastic middle section 711 causes damping sense to be generated by the user rotating hand feeling, and the damping sense is increased along with the increase of the rotation amplitude, when the elastic middle section 711 is rotated to the next concave portion 332 corresponding to the elastic middle section 711, the elastic middle section 711 and the convex portion 331 are separated, so that the user rotating hand feeling suddenly becomes loose, and the elastic middle section 711 is rapidly clamped in the concave portion 332 through rebound resilience and collides with the surface of the concave portion 332, a certain collision sound can be generated, so that the user can precisely rotate to a required option in hand feeling and hearing, and the accuracy and the experience of the user operation are improved.

When the elastic middle section 711 is in a state of being clamped in the concave portion 332, the state is normal under non-operation, and in the state, two side edges of the elastic side section 712 are propped against the corresponding positioning structure 73, so that the position of the elastic strip 71 in the main body seat 1 is locked, and the situation that the elastic strip 71 deviates from the preset position due to shaking when a user moves the kitchen appliance operation device can be avoided.
