Compared with the second embodiment, the present embodiment further specifically discloses the structure of the trigger mechanism 5; the trigger mechanism 5 includes a trigger rod 51, a float 52 and a limit assembly 53; the trigger rod 51 is slidably connected to the partition plate 6, the float 52 is connected to the trigger rod 51, the limit assembly 53 is connected to the partition plate 6, and one end of the limit assembly 53 is clamped with the connecting plate 43; the limit assembly 53 includes a limit frame 531, a limit spring 532 and a limit block 533; the limit frame 531 is connected to the partition plate 6, one end of the limit block 533 is located in the limit frame 531, the limit block 533 passes through the partition plate 6 and is clamped with the connecting plate 43, and the limit block 533 is penetrated by a guide hole 534; the trigger rod 51 passes through the limit frame 531 and the limit block 533 and is slidably connected to the limit frame 531 and the limit block 533; the limit spring 532 is located in the limit frame 531, one end of the limit spring 532 is connected to the limit frame 531, and the other end of the limit spring 532 is connected to the limit block 533.
