And the cracked paint can be avoided from falling into food, and the safety is improved.

[0033] Specifically, refer to Figure 2 The body 100 comprises a surrounding plate 101, the surrounding plate 101 is covered to form a cavity 102, the mounting surface 104 is located in the cavity 102, and the mounting surface 104 is arranged away from the inner side wall of the cavity 102. It can be understood that the mounting surface 104 is not connected with the inner side wall of the cavity 102, and the distance between the mounting surface 104 and the outer peripheral wall of the surrounding plate 101 is less than the length of the connecting column 111, so that the connecting column 111 can be ensured to protrude from the body 100, and the expansion connection is facilitated.

[0034] It is understood that a transmission box 103 is provided in the body 100, and the transmission box 103 is located in the cavity 102, and there is a preset distance between the outer peripheral wall of the transmission box 103 and the inner peripheral wall of the cavity 102, and the mounting surface 104 is located on the outer peripheral wall of the transmission box 103.

[0041] Specifically, the movable element 116 is inserted into the mounting cavity from the outer peripheral wall of the connecting column 111, and the end of the movable element 116 protrudes from the inner wall of the mounting cavity. It can be understood that when the mechanism for outputting power outward is inserted into the mounting cavity, the movable element 116 can be pressed and retracted, so as to trigger the inductor, the inductor sends a signal to the controller, so that the controller controls the motor and reduces the output torque of the motor, which can avoid that the torque output by the output shaft 113 is too large, thereby avoiding that the connecting column 111 is loose after long-time use, or avoiding that the output shaft 113 is broken due to the too large output torque.
