Operation principle is stored in the expansion of electric fan：
Original state：Slide the vertical state of support base 21 to be accommodated in lifting groove 100, now three blades 24 are perpendicular to leaf
Upwards, three blades 24 are also accommodated in lifting groove 100 for bar 23 and direction；Support feet 11 is completely hidden in support feet and slided
In groove 104, and it is conditioned bolt 12 and fixes, lifter rack 35 is in bottom and engaged with gear ring 211；
When needing to organize work, manual actuation rotary handle 31, rotary handle 31 is by driving worm screw 32, driving worm gear 33
Rise with the driving lifter rack 35 of threaded rod 34, limited due to sliding support base 21 by lifting groove 100, so can not rotate, only
It can rise in the presence of lifter rack 35, when sliding the arrival highest order of support base 21, slide the restriction state of support base 21
Release, the lifter rack 35 of rising slides outside cylinder of the back rotation of support base 21 until sliding support base 21 by gear ring 211
Face is resisted against the lower wall of horizontal setting groove 101, now slides the direction level of support base 21 backward and position is limited, then
Three blades 24 are exerted oneself back rotation until concordant with blade seat 23, now blade 24 is limited by the first spring-loaded plunger 2312,
Finally unscrew regulating bolt 12, pull out support feet 11 toward outboard end tightens regulating bolt 12 again, and now support feet 11 is limited in exhibition
Open state, since then electric fan be fully deployed.
