In the utility model, cancelled the setting of time-delay mechanism as described in the background art, in order to make the supply of the gases at high pressure that piston assembly is subjected to early than the action of feeding device for nail, the utility model is by these means of crooked wireway, make gases at high pressure be subjected to resistance at bend, prolonged the gases at high pressure circulation time, simultaneously, the curved guide pipe has also prolonged the length of wireway, high-pressure gas flow has also been increased through the path, so just reached the purpose of the supply of the gases at high pressure that piston assembly is subjected to early than the action of feeding device for nail.
In addition, outlet passageway is arranged in the cylinder head, also reached the purpose of the supply of the gases at high pressure that piston assembly is subjected to early than the action of feeding device for nail, because, the gases at high pressure that produced in the combustion chamber at first are to flow to piston assembly, just flow in the wireway by outlet passageway thereafter, this certainly will produce a time delay, so can achieve the above object.
Further, described outlet passageway vertically is arranged in the cylinder head, is provided with the outlet nozzle that is communicated with outlet passageway in the outlet of outlet passageway, and described wireway is communicated with outlet passageway by outlet nozzle.
For the ease of being connected of wireway and outlet nozzle, described bend is a bend pipe, and described wireway is communicated with outlet nozzle by bend pipe.
In order to prevent that revealing from appearring in gases at high pressure in flow process, reduce the pressure of gases at high pressure, also compress and the effect that is connected in order to play simultaneously, described outlet nozzle and outlet passageway junction, outlet nozzle and bend pipe junction and wireway and little cylinder junction are provided with swivel nut.
Described wireway is metal tube or rubber plastic pipe, certainly, also can utilize other materials to make wireway according to actual needs.
For the waste gas in the little cylinder is discharged, be provided with the steam vent that is communicated with little cylinder around the described little cylinder baffle, described steam vent is positioned at the bottom of little cylinder baffle.
Owing to adopted technique scheme, the utlity model has simple and direct, the convenient and reliable advantage of structure, it adopts a wireway just can realize prolonging the purpose that gases at high pressure are supplied with feeding device for nail, prevented from nailing and sent to produce interference between the nail, can carry out nailing accurately and send the work of nail, but also reduce production cost.
