According to the above, when the user does not press the trigger 12 (as shown in FIG. 5), the high-pressure air in the main air chamber u is introduced into the first air chamber 63 through the trigger valve 121 and the trigger air passage 13 to collect pressure. And introducing the pressures in the second, third and fourth air chambers 64, 71, and 72 through the second, third and fourth air grooves 641, 711 and 721, respectively; the axial through holes 51 can be connected to the air distribution ring 5 The upper and lower two-layer fourth air chambers 72 are separated; at this time, the high-pressure air in the first air chamber 63 drives the cylinder 6 to move to the positioning together with the upper magazine and the third air chamber 71. The high-pressure air and the lower spring 77 - drive the sliding sleeve valve 7 to move down to the position, while the main air is in the top /, ' middle, the bottom valve holes 66, 67, 68 and 69 are each positioned by the valve 14, the nailing piston 2 The neutral valve 75 and the lower position valve 76 are closed to prevent high pressure air in the -1 and ® chambers 63, 64, 71, 72 from entering the cylinder. The I check valve 74 prevents the high pressure air in the third air chamber 71 from entering the push nail air passage 10 and the push nail cylinder chamber 30 via the annular groove 200806440 70, the valve hole 751 of the neutral valve 75, and the radial through hole 52. . When the user presses the trigger 12 (as shown in FIG. 6), the trigger valve 121 closes the high-pressure air in the main air chamber 11 into the trigger air passage 13, and opens the trigger air passage 13 to communicate with the outside atmosphere, so that the first air chamber 63 The high-pressure air inside is vented to reduce the pressure, so that the high-pressure air in the second air chamber 64 drives the cylinder 6 up to the position, and the valve 14 is opened and the air path between the second air chamber 64 and the main air valve hole 66 is opened. In order to continuously introduce high-pressure air into the top plenum 60 in the cylinder 6, the nail-carrying piston 2 is driven to rapidly move the nail; at this time, the residual gas in the bottom plenum 61 can be vented by the lower escaping hole 15 of the bottom edge of the gun body 1. Discharge to the outside; and when the nail piston 2 is moved down to connect the top air chamber 60 with the middle valve hole 68, the high pressure air continuously introduced into the top air chamber 60 passes through the middle valve hole 68 and the middle valve 75. The valve hole 751, the radial through hole 52 and the push nail air passage 10 are continuously introduced into the push cylinder chamber 30 to drive the pusher piston 32 to displace the nail. When the user releases the trigger 12 for an instant (as shown in FIG. 7), the trigger valve 121 resumes supplying high-pressure air into the first air chamber 63 to drive the cylinder 6 to move down and the nailing piston 2 has not moved up to the closed state. At the top valve hole 67, the high pressure air in the third air chamber 71 can be vented to the top air chamber 60 of the cylinder 6 via the top valve hole 67, so that the sleeve valve 7 is driven by the high pressure air in the fourth air chamber 72. Move to open the bottom position valve 76, and guide the high pressure air in the fourth air chamber 72 to enter the bottom air chamber 61 through the bottom valve hole 69, and quickly drive the nail piston 2 to move up and reset; at this time, the top air chamber 60 is inside. The residual air can be discharged to the outside by the escaping hole 16 at the top of the gun body 1, so that a low pressure state is formed in the top plenum 60; at this moment, the high-pressure air in the cylinder chamber 30 is pushed through the phase 12 200806440 to push the nail air passage. 10. The radial through hole 52, the valve hole 75i of the neutral valve, and the production groove 7〇 push the flexible collar 742 of the check valve to open the check valve through the number of through holes 74 The air is vented to the top floor 'room: through the top tank 73, and is discharged to the outside together. 32 reset push pin. Continued when the needle piston 2 is moved up to the position (as shown in item 5), = complex = the top, middle and bottom pupils 66, 67, 68 and 69, so that the high pressure air: ,, Bei Yudi one, two The three and four air chambers 63, 64, 71, and 72 cause the slide 7 to be moved down to return to the initial state of the untrimmed trigger 12. As can be seen from the above, the axial through hole 51 of the gas distribution ring 5 and the diameter "guided to maintain a certain pressure of high pressure air, driving the needle to live: and Ϊ = plug 32 to quickly nail and push the effect of the nail" Radial through hole 52 Force: ΪΓ push the nail cylinder chamber 3 高压 high pressure air quickly discharge the pressure of the 32-bit j (b) operation over the money, can lift the nail to move the nail and push the nail action rate And stability. _ nail wall tr more more specific implementation of the 'the invention can be pushed 33 (such as ^ surface) open a fugitive hole 34 with the outside atmosphere (1 figure 9:): or push nail The piston 32 is opened - equivalent to the escape of the gas _, not) 'so that when the nailing piston 2 is moved up and reset (the drawing can assist the release of the high pressure air in the push cylinder chamber 30 to speed up the scale section ^ 32 resets the speed of the push pin; and, the hole of the escape hole 33 or 34: the ventilating sectional area of the second channel of the chamber 2, so as to facilitate the pushing of the nail, the second air into the pressure air, and the drive push The displacement of the nail piston 32 can prevent the pressurized air from quickly escaping to the outside.
