[0026] Using the above solution: by rotating the handle locking pin 32 so that one end of it firmly presses against the inner side below the handle body 20, the butterfly valve handle assembly 2 and the handle locking assembly 3 can be quickly locked. When it is necessary to rotate and adjust again, the handle locking pin 32 can be screwed down to rotate and adjust again.

[0027] The limiting tooth plate assembly 4 includes a fan-shaped limiting plate body 40. A limiting locking tooth groove 41 is provided at one outer end of the fan-shaped limiting plate body 40, and a rotating limiting plate 42 is fixedly provided at the other outer end of the fan-shaped limiting plate body 40.
