7. The variable wind direction heat gun for electronic information engineering according to claim 6, wherein: the diameters of the guide cylinder, the second outlet, the air inlet and the first outlet are not smaller than the diameter of the air nozzle pipe.
8. The use method of the variable wind direction heat gun for the electronic information engineering based on any one of claims 1 to 7 is characterized by comprising the following specific steps:
(1) Firstly, observing the size of an area needing to be finished of a product, judging the area, and mounting the variable wind direction assembly on the air nozzle pipe when the area sprayed by the air nozzle pipe is too large to meet the requirement;
(2) Adjusting the variable wind direction component, rotating the rotary diversion wind guide part by a certain angle, and then fixing the rotary diversion wind guide part through a mandril, so as to lock the distance between the wind inlet part and the diversion wind guide part in the initially adjusted variable wind direction component;
(3) Then, the coverage area of the heat conducting disc is further determined by aligning the primarily adjusted hot air gun with the heat conducting disc, whether the area on the heat conducting disc is close to the area to be finished of the product or not is observed, if the area on the heat conducting disc is not close, the area needs to be adjusted again, and if the area is close, the area can be used, and the step realizes accurate adjustment of the air outlet size of the hot air gun;
(4) And then, opening a switch of the hot air gun body, and heating the product area to be trimmed.
9. The method for using the variable wind direction heat gun for electronic information engineering according to claim 8, wherein: the heat conducting disc (15) in the step (3) comprises a disc body (15-1), wherein a thermosensitive color-changing material (15-2) capable of changing color along with temperature change is coated on the upper end face of the disc body (15-1), a longitudinal marking line (15-3) and a transverse marking line (15-4) which are arranged along the center are distributed on the disc body (15-1), scale marks (15-5) are respectively distributed on the longitudinal marking line (15-3) and the transverse marking line (15-4), annular observation rings (15-6) which are circumferentially arranged at equal intervals are sequentially distributed on the disc body from the center outwards, and observation grooves (15-7) which are radially arranged and used for observing and estimating an area to be repaired are also distributed on the disc body.
