Described adapter 2 is fixed on one end of power transmission shaft 1 by screw a3, one end of power transmission shaft 1 by adapter with
Air drill unit head connects, and is rotated.Bushing 5 is socketed in inside sleeve 4, and power transmission shaft 1 is in bushing 5 by can freely turn
It is dynamic.The lower section of the right side of sleeve 4 and gear-box 6 by being welded after pressing excircle of sleeve centering reference axis, the other end of power transmission shaft 1
Gearhead is in the idler gear 9 carried out in gear drive, with gear-box 6 interior with roller box 6 and screws first 7 progress gear drive.Tooth
Idler gear 9 is fixed by bearing pin 10 in roller box 6, the interference fit of bearing pin 10 passes through the endoporus of idler gear 9, and the gap of bearing pin 10 coordinates
In gear-box 6 and cover plate 8, for fixing the position of two idler gears 9.Screw first 7 and gear is fixed on by the both sides face of cylinder
In case 6 and cover plate 8, idler gear 9 is with screwing first 7 ratcheting transmissions.Gear-box 6 is locked with cover plate 8 by screw b11.
The precision groove for having 30mm to grow on the inside of the one end of sleeve 4 is connected with bushing 5, and the endoporus of bushing 5 is finished, in bushing 5
Hole, which applies lubricating oil, makes the steady transmission of power transmission shaft smooth rotation in bushing, i.e. power.
Nut installation tool carries out the powered rotation of L-type, and gear-box 6 using travelling gear in cover plate 8 to screwing head with being entered
Action edge conducts, and realizes in aircraft L-type narrow space by the self-locking screwed in first 7 pairs of narrow spaces of nut installation tool
Nut carries out screwing installation.
The beneficial effects of the utility model are：This nut installation tool solves the narrow intracavitary self-locking nut peace of aircraft L-type
The practical problem of dress.Worker's installation effectiveness is high, easy to operate.It is easy that structural member is manufactured, and manufacturing cost is low.Application field is wide
Wealthy, the working method method of this instrument can carry out the ductility design of other model aircraft narrow space inner nut installations.
