The intelligently retractable and speed-variable hand mixer according to claim 5, characterized in that: The cavity wall of the engaging cavity (110) is provided with a first sliding groove (113), and the outer surface of the engaging portion (210) is provided with a first sliding block (220), and the first sliding block (220) can be inserted into the first sliding groove (113); When the engaging portion (210) moves up and down relative to the engaging cavity (110), the first sliding block (220) moves in the first sliding groove (113).

7. The intelligently retractable and speed-variable hand mixer according to claim 6, characterized in that: The cavity wall of the coupling cavity (110) is provided with a first opening (114) which is interconnected with the first sliding groove (113), and the first sliding block (220) can be screwed into the first sliding groove (113) through the first opening (114); the main machine (10) and the coupling part (210) are provided with an anti-rotation structure for restricting the relative rotation of the two.

8. The intelligently retractable and speed-variable hand mixer according to claim 4, characterized in that: The joining cavity (110) is provided with a joining platform (120) which moves up and down relative to the joining cavity (110), and a second elastic element (160) is provided in the joining cavity (110) above the joining platform (120), and the second elastic element (160) applies a downward force to the joining platform (120).

9. The intelligently retractable and speed-variable hand mixer according to claim 2, characterized in that: The mode controller (60) includes a touch element (610) arranged on the upper surface of the host (10), and a menu main board (620) matching the touch element (610) is arranged in the host (10), and the menu main board (620) is communicatively connected with the control module (130).
