A matched cushion 30 is equipped in the connector 2.
The application method of the utility model is as follows:
Motor is installed in gear-box 1, eccentric axis seat 10 can be driven by motor, eccentric shaft 11 is enable to occur
Rotation, when eccentric shaft 11 rotates, eccentric shaft 11 then can be mobile towards 25 direction of pressing portion of the first rocking bar 24, while partially
The rotation of mandrel 11 drives second piston 7 to move to right by piston arm 12, makes second piston 7 constantly towards towards in the second cylinder 5
Portion is goed deep into, and the air pressure in the second cylinder 5 is continuously increased at this time, and the gas in the second cylinder 5 can then pass through the second venthole 18
It is squeezed into ventilation chamber 19 by second piston 7, is entered in the first cylinder 4 followed by the first venthole 17, first is logical
The air pressure of 17 position of stomata is continuously increased, and since locating plate 13 is stuck by latch 14 and the card slot 9 on striker 8, is being hit
When pin position is limited, the position of first piston 6 is also limited therewith, and first piston 6 not will receive the influence of air pressure at the moment
It moves.
With the lasting rotation of eccentric shaft 11, eccentric shaft 11 finally can then be struck in the pressing portion 25 of the first rocking bar 24,
The position of guide post 22 be directed to hole 21 limit in the case where, the first rocking bar 24 then can under the thrust of eccentric shaft 11 with
It is rotated centered on guide post 22, when the first rocking bar 24 rotates, the first rocking bar 24 then can drive the by link arm 26
Two rocking bars 27 rotate, and the second rocking bar 27 is connected with connecting tube 23, and connecting tube 23 rotates therewith, due to locating plate
13 are fixed on 23 upper end of connecting tube, therefore locating plate 13 rotates therewith, card slot of the latch 14 on locating plate 13 from striker 8
It is detached in 9, when eccentric shaft 11 can touch pressing portion 25 and push to the first rocking bar 24, second piston 7 is
Through thoroughly deeply to the inside of the second cylinder 5, the air pressure of 17 position of the first venthole is had become greatly, when striker loses locating plate
After 13 limitation, first piston 6 can then eject striker 8 moment under high pressure effect, thus got nail by striker 8,
After having played a nail again, first piston 6 drives 8 return of striker, and connecting tube 23 is in the effect return of torsional spring 28, locating plate 13
With 23 return of connecting tube, the latch of itself 14 is stuck in the card slot 9 of striker 8 again, reaches actually required to next air pressure
When, locating plate 13 can be then again turned on, and be thusly-formed circulation.
In summary it is found that the utility model is compressed into a certain extent when the air pressure in the second cylinder 5, eccentric shaft 11
The pressing portion 25 of first rocking bar 24 will be pushed, open locating plate 13 eventually by rocker assembly, at this time the second cylinder 5
Interior high pressure can then pass sequentially through the second venthole 18, ventilation chamber 19 and the first venthole 17 and be directly applied to the first cylinder
On first piston 6 in 4, after the limitation that striker 8 loses locating plate 13, first piston 6 will moment will under high pressure effect
Striker 8 ejects, to be got nail by striker 8, this nailing mode can increase to one in the air pressure in the first cylinder 4
Striker 8 will be ejected automatically after determining degree, so realize the effect of automatic nailing, avoided after air pressure increases to requirement also
Needing staff to open locating plate leads to the situation of nailing process complexity, improves nailing efficiency to the full extent.
Matched cushion 30 is equipped in connector 2, when first piston 6 under high pressure effect push up outwardly by moment
When, cushion 30 can play buffer function to first piston 6, avoid 6 impact force of first piston is excessive from leading to connector 2 and
The case where one piston 6 damages.
