A second compression spring is provided in the pressing hole. The second compression spring abuts against the button shaft so that the button shaft has a tendency to be pushed upward;

[0013] In the closed cover state, the pressing hole corresponds to the pin slot. Under the action of the first compression spring, the upper end of the safety pin extends into the lower end of the pressing hole to position the knob base. When opening the cover, the button shaft is pressed downward to press the safety pin so that it exits the pressing hole, and then the knob base can rotate.

[0014] Furthermore, the safety pin has a first step, and the first compression spring abuts against the first step. The button shaft has a second step, and the second compression spring abuts against the second step.

[0034] On the cross frame 7, there is also a driving mechanism. The driving mechanism can drive the left driving piece 3 and the right driving piece 4 to move inward simultaneously, so that the left clamp 5 and the right clamp 6 lock the pot body and the pot lid to be in the closed lid state; the driving mechanism can also drive the left driving piece 3 and the right driving piece 4 to move outward simultaneously, so that the left clamp 5 and the right clamp 6 unlock the pot body and the pot lid to be in the open lid state.

[0035] The driving mechanism includes: a knob base 8 provided on the cross frame 7. The lower end of the knob base 8 has a left driving pin 9 and a right driving pin 10. The left driving pin 9 is inserted into the left driving piece 3, and the right driving pin 10 is inserted into the right driving piece 4. Thus, when the knob base 8 rotates in the first direction, driven by the left driving pin 9, the left driving piece 3 moves outward, and driven by the right driving pin 10, the right driving piece 4 moves outward; when the knob base 8 rotates in the second direction opposite to the first direction, driven by the left driving pin 9, the left driving piece 3 moves inward, and driven by the right driving pin 10, the right driving piece 4 moves inward.

[0036] In one embodiment, there is also a safety pin 11 between the knob base 8 and the cross frame 7, so that the knob base 8 cannot be rotated randomly. There is a vertical pin slot 12 on the cross frame 7. The safety pin 11 is placed in the pin slot 12, and a first compression spring 13 is also provided in the pin slot 12. The upper end of the first compression spring 13 abuts against the safety pin 11, and the lower end of the first compression spring 13 abuts against the bottom surface of the pin slot 12, so that the safety pin 11 has a tendency to be pushed upward; a vertical pressing hole 14 is provided on the knob base 8. A button shaft 15 is provided in the pressing hole 14. The upper end of the button shaft 15 is exposed so that it can be pressed downward. A second compression spring 17 is provided in the pressing hole 14. The second compression spring 17 abuts against the button shaft so that the button shaft 15 has a tendency to be pushed upward; in the closed lid state, the pressing hole 14 corresponds to the pin slot 12. Under the action of the first compression spring 13, the upper end of the safety pin 11 extends into the lower end of the pressing hole 14 to position the knob base 8; when opening the lid, the button shaft 15 is pressed downward to press the safety pin 11 so that it exits the pressing hole 14, and then the knob base 8 can rotate.

[0037] In one embodiment, the safety pin 11 has a first step, and the first compression spring 13 abuts against the first step; the button shaft 15 has a second step, and the second compression spring 16 abuts against the second step. The pressing hole 14 includes an upper section and a lower section, and the aperture of the upper section is larger than that of the lower section.
