In one embodiment, a through hole 8 is provided at the front portion of the toggle member 7, and a linkage shaft 9 is provided at the rear portion of the operating handle 4. The linkage shaft 9 penetrates into the through hole 8 and has a movable space, thereby achieving the purpose of movable connection between the two.

[0044] The middle part of the toggle member 7 is rotatably connected to the handle body 1 through a toggle shaft 10, and the rear part of the toggle member 7 is movably connected to the rear part of the moving plate 2. In one embodiment, a shift fork 11 is provided at the rear part of the toggle member 7, and a shift hole is provided at the tail of the moving plate 2, and the shift fork 11 extends into the shift hole, so that the toggle member 7 can drive the moving plate 2 to move through the shift fork 11 after it is rotated.

[0045] After holding the handle body 1 and pinching the operating handle 4, the operating handle 4 rotates around the handle shaft 5 at the front, so that the rear of the operating handle 4 drives the toggle member 7 to rotate around the toggle shaft 10. After the toggle member 7 rotates, the fork 11 at the rear thereof drives the movable plate 2 to move backward, thereby making the interlayer narrower. At this time, the pot can be clamped in the interlayer of the detachable pot handle of the utility model.
