One switch 10 is rifle tool switch starting two-way pneumatic motor 4, since two-way pneumatic motor 4 is to connect and fix to connect with crosspoint tip screwdriver head
Together, so crosspoint tip screwdriver head will be rotated according to the rotation direction of setting, it can thus be used to holding screw 50 or twist
Loose screw 50；When the motor shaft of holding screw 50 and induction machine 40 can not advance even at the cost of one's life, operator's hand-held gun has this at this time
While body 1 moves back a small distance, second switch 18 being stirred with finger and opens two-position five-way valve, the movement of cylinder 5 at this time pushes
Shift fork 6 moves forward, and pushes sleeve to front end, at this time can be with sleeve come locking nut 60.Control 4 opposite direction of two-way pneumatic motor
Rotation can be used to loosening nut 60, unscrew screw 50.
In conclusion rifle provided in an embodiment of the present invention has component, it can be used for the screw 50 of fan blade 30 on washing machine
Component tightening station, can with holding screw 50 and fixed locking nut 60 it is same rifle had on realize, it is easy to assembly, save work
People's assembly time promotes Workshop Production efficiency.
