How's the working mechanism of cocking on the pump suction in a Hakko desoldering gun or alike product?

Assuming that you really are asking about desoldering guns, they do not use cocked springs to generate suction, so there is no cocking mechanism. The suction is most often produced using a diaphragm vacuum pump. Some models instead use a venturi "ejector" to transform pressurized air into vacuum.

Cocked springs are used in tools called "solder-suckers" that are manually, not electrically, operated.

I think he is asking about the pace patented slurp method where it has a higher then usual vacuum pull for a short period of time before it slows down. They 'yank' solder with a pressure pulse, supposedly. Something like overloading the pump for a half second before it slows down to a normal pull.

I own a Pace desoldering station and can confirm that’s exactly how they work: they give the (12V) motor a ~24V pulse for about 1/2 second, then drop to 12V for continuous suction until released. They call it “SnapVac” IIRC.
