In the present embodiment, the edge of imperfect gear 44 offers notch compatible with nail gun screw 15.
The operation principle of the present invention is that: when above following closely, by the first spring push-rod 32 and second spring push rod 33 by spring pressure
Contracting makes spring longest end (spring is in upper 26 side of nail-plate) not in the working range of upper nail-plate 26, and opening upper nail-plate 26 at this time will
Nail gun screw 15 is put into ailing machine, and nail gun screw 15 will slide into slideway along inclined nail Leading board 27, and upper nail-plate 26 is pushed away
Original position is returned, nail pressing plate 30 will push down one end of nail gun screw 15 at this time, unclamp the first spring push-rod 32 and second spring push rod
33, spring will shift nail gun screw 15 at imperfect gear 44 onto along guide rail, in this way, nail is completed (can repeatedly beat in preparation
It opens nail-plate 26 and repeats the above process the more nail gun screws 15 of addition).
Muzzle is pushed when nailing for the first time, third push rod 42 connects the shell with pipette tips after the body of a gun pushes certain distance
Touching, when 42 top inclined push pipette tips of third push rod, third push rod 42 will press 47 slide downward of the 7th spring along slideway 46, together
When third push rod 42 imperfect gear 44 will be driven to rotate, when gun body moves to extreme position, conduit is overlapped with screw slideway, no
Complete gear wheel 44 also will be moved to extreme position, and nail gun screw 15 will promote pipette tips by the first pushing block 8 by imperfect gear 44
Interior, the first pushing block 8 will be positioned with positioning baffle 7 for nail gun screw 15.
Screw pins motor switch after being sent in pipette tips pushes gun body drill bit 4, and nail gun screw 15 will be with drill bit 4 one
It rises forward, one end of 15 microcephaly of nail gun screw first passes through positioning ring, with the promotion of nail gun screw 15, one end of nail gun screw 15
Position will be reached the limit of to contact with the first pushing block 8, since one end of the first pushing block 8 is that bevel structure pushes nail gun screw 15, In
First pushing block 8 rotates two sides under the promotion of nail gun screw 15, also will be upward along slideway simultaneous with the positioning baffle 7 on inclined-plane
Mobile, nail gun screw 15 passes through the first positioning ring 10, therefore the first pushing block 8 and positioning baffle 7 before moving to extreme position
It remains to after leaving original position along straight-ahead motion；Drill bit 4 moves forward, and push rod 39 will repeat being moved through for first time
Journey is completed to promote screw into the movement in pipette tips.
After screw is installed, the body of a gun retracts, and the shell that third push rod 42 loses pipette tips will be by the 7th spring 47 after acting on
The extreme position contacted with gun body is pushed up, while the notch of imperfect gear 44 will be contacted with nail gun screw 15 again.
The technical means disclosed in the embodiments of the present invention is not limited only to technological means disclosed in above embodiment, further includes
Technical solution consisting of any combination of the above technical features.It should be pointed out that for those skilled in the art
For, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also considered as
Protection scope of the present invention.
