One flange 46 is arranged at the bottom of main body 7, the inner chamber that 31 tops just are inserted into this flange 46 is taken in transition, suction nozzle 30 tops are screwed in the hole of transition adapter 31 with screw thread, 31 tops are taken in transition has flange 47 to be inserted in the inner chamber of transition adapter 31, sealing ring 48 is housed therebetween, connector 29 tops are sleeved on above the bottom of suction nozzle 30, O RunddichtringO 35 is housed therebetween, valve 28 tops are contained in the endoporus of connector 29, fluid sealant 27 is equipped with in the valve bottom, and gas cylinder 49 tops are contained between transition adapter 31 and the suction nozzle 30.

Outer cylinder 13 usefulness bolting front shrouds 16 and sealing ring 50 is housed, inner cylinder tube 34 front end plug-in mounting main pistons 19 and join with striker 17, striker 17 prolongs rifle mouth 37 horizontal-extendings, inner cylinder tube 34 has aperture 51, between inner cylinder tube 34 and the main piston 19 sealing ring 52 is housed, main piston 19 usefulness nuts are fixed on striker 17 right-hand members, and base 15 is sleeved on the outside of main piston 19, and sealing shock-reducing rubber 18 is housed therebetween.

Auxiliary piston 12 is contained in the outer cylinder 13, and sealing ring 53 is housed on the auxiliary piston 12, spring 23 be sleeved on inner cylinder tube 34 right-hand members above, by auxiliary piston 12 nose holddown spring 23, in the connecting plate 10 right part inner chambers sealing ring 16 is arranged with connecting plate 10, left part also has sealing 54.

There is voussoir 21 bottom of outer cylinder 13 and is positioned at the articulated slab casing 20 of outer cylinder 13 bottoms, trigger 25 is contained on switch 7 lower flange 38, its preceding end in contact finger 24, this finger 24 are contained in the right part of resistance position pin 22, and the flange 55 of resistance position pin 22 is in auxiliary piston 12 lower channel 56.

The specific embodiment

On workpiece during nailing, rifle mouth 37 is pressed on position and the cocking 25 of wanting nailing, trigger 25 rotates counterclockwise, trigger 25 front ends drive finger 24 and spacer pin 22 are clockwise rotated, when spacer pin 22 forwards certain angle to, the auxiliary piston 12 that hangs on the spacer pin 22 breaks away from spacer pin 22, travels forward at a high speed under the elastic force effect of spring 23, and spacer pin 22 resets again under the effect of the restoring force of spring 23.The proal auxiliary piston of high speed 12 drives hammers 2 and also travels forward at a high speed, when hammer 2 moves to switch base 4 with regard to impact switch seat 4; Because switch 6 closely closes with switch base 4 and joins together, make the flange 43 of switch 6 break away from switch glue 33, gases at high pressure in main body 7 chambers flow out from flange 43, because the spring 41 on the switch 6 makes the flange 43 of switch 6 be pressed in rapidly on the switch glue 33 with draught head, sealed the gas in main body 7 chambers again, and only emit a certain amount of gases at high pressure, these gases at high pressure enter in the chamber of

switch base

4 and 33 formation of switch glue, because switch 6 communicates with the endoporus of switch base 4, gas just by the tapping of switch base 4 in endoporus flows to the chamber that active joint 8 and main body 7 form, gases at high pressure promote active joint 8 and travel forward, when moving to dividing plate 9, active joint 8 enters in the O RunddichtringO 11 inside of inner cylinder tube 34 and atmosphere is cut off, gas flows in the chamber of main piston 19 and inner cylinder tube 34 formation through the inner chamber of active joint 8, gases at high pressure just push away main piston 19 and travel forward, drive striker 17 and travel forward at a high speed, finish nailing thereby striker 17 promotes the rifle nail of 37 li in rifle mouth.After main piston 19 moves to front end and finishes nailing, the main piston 19 of this moment has been crossed the aperture 51 of inner cylinder tube 34 front ends, gas in the inner cylinder tube 34 is still gases at high pressure, gas is just flow in the chamber of inner cylinder tube 34 and outer cylinder 13 and auxiliary piston 12 by aperture 51, bullet is housed to valve block 14 on the aperture 51, the gas of inflow can not flow backwards back in the inner cylinder tube 34.

1. discharge residual air: the gas pressures in this moment inner cylinder tube 34 descend greatly, and return under active joint 8 effect of spring restoring force thereon allows inner cylinder tube 34 communicate with atmosphere, emits gas to atmosphere.

2. piston return: gas flows into the front end of main piston 19 from the perforate on the base 15, promotes main piston 19 and moves backward, finishes the piston return.

3. load: auxiliary piston 12 motion compresses spring 23 backward under the effect of inflow gas pressure when auxiliary piston 12 moves to the rear end, hangs over to finish on the spacer pin 22 to load.
