Description of the invention: 1. The invention relates to a main gas valve driving gas path of a nail grab, which is a kind of fixed air cylinder top, which is responsible for opening the valve and closing the valve resistance. Breaking high-pressure air into a valve member for driving a nail in the cylinder; the driving air passage is a high-pressure air passage disposed between the trigger valve and the main air valve for driving the main air valve to open and close the valve; and the trigger The valve is a valve that can be opened when the valve stem is pressed to guide the high-pressure air to drive the main valve up. _ [Prior Art] The prior art is equipped with a fixed type of cylinder and a trigger valve, which can be found in the national patent publications Nos. 439630 and 1263565; wherein the trigger valve can be used to press the valve stem The valve is opened to guide the high-pressure air directly into the _ fixed cylinder to drive the nail to the lower piston. The advantage is that the main gas valve and its driving gas path can be omitted from the top of the fixed cylinder, but the disadvantage is that the rate of guiding the high-pressure air into the fixed cylinder is too slow, and the damage is high. The amount of piston can be used only for smaller nails and not for medium and large nail guns. In addition to the above, a nail gun equipped with a trigger valve, a fixed cylinder, and a main air valve can be seen in the prior art. For example, in the case of U.S. Patent Nos. 6,533,156, 6,779,699 and 6,006,795, the main air valve is Separated and disposed on the top of the fixed cylinder, and a main airflow channel for collecting high-pressure air between the trigger valve and the main air valve, the laminating valve can discharge the high-pressure air in the main airflow passage when the valve stem is buckled. To drive the main air valve to open the valve, guide the high-pressure air into the fixed cylinder to drive the nail to move the nail under the nail; however, the distance of the main air passage is too long, so as to guide and discharge high-pressure air The rate is too slow for 5 1331072, which detracts from the amount of high-pressure air-driven main valve opening and closing the valve, and even affects the proper rate of continuous nailing, which needs to be improved. SUMMARY OF THE INVENTION The present invention has been made in view of the problems of the prior art described above, and its main object is to provide a quick-drive main valve to move up and down for a nail that is equipped with a trigger valve, a fixed cylinder, and a main air valve. Drive the gas path. In order to achieve the above purpose, the main air valve is disposed on the top of the fixed cylinder, and the trigger valve is a type that can open the high pressure air to drive the main air valve up and down when the valve stem is pressed, and must be disposed in the gun body. a high pressure air collecting chamber and a main air passage; and an intake passage connecting the pressure collecting chamber and the main air passage and a exhaust passage connecting the main air passage and the outside air in the trigger valve At the same time, the trigger valve has a valve rod that can be pressed and released, which can close the intake passage and open the exhaust passage when the valve stem is released, and close the exhaust passage and open the intake passage when the valve is pressed. Guide the high-pressure air into the air. Quickly drive the nail in the cylinder and use the piston rod to move the nail down. According to the above, in order to construct the driving gas path of the main gas valve of the present invention, a ring-shaped valve plug is formed at the bottom end of the main gas valve, and is disposed between the outer wall of the cylinder and a guiding wall surface, and the top of the valve plug is The high pressure air in the pressure collecting chamber is in contact with each other, and a bottom portion of the valve plug forms a main air chamber communicating with the intake and exhaust passages through the main air passage, and the main air chamber collects high pressure air through the intake passage when the valve stem is pressed. The driving valve plug and the main air valve are synchronously moved up, and the high-pressure air in the main air chamber is discharged through the exhaust passage when the valve stem is released, so that the high-pressure air/air-driven valve plug and the main air valve in the collecting chamber are synchronously moved down and reset. - Based on the above, the present invention not only has a main air valve disposed on the top of the stationary cylinder, but also can be disposed by the valve plug, and the main air valve is extended downward to receive the main 6 valve when the valve is opened. The inside of the gun body 1 is a type of air-driven main air valve 3 that can be moved inside, and is placed in the airflow ί, ι°ι to maintain a certain constant pressure of high-pressure air. The pressure collecting chamber 1〇 and an active room 22 (with the 1° slab valve 2' are included in a valve seat 21 to slide a shuttle to release the 浐°Fig. 1& and slide in the shuttle A spring 24 can be set between the movable valve 22 and the valve stem 23, and the trigger 24 can be inserted into the trigger body 1 via the trigger. The user can valve The lever 23 is lowered and the buckle valve stem 23 is moved up, and the trigger chamber 28 can be used to release the chamber 10 and the main wide reset. Further, the trigger valve 2 is formed to communicate with the collecting airflow passage and the 11^ flow passage 11 An intake passage 25, and an exhaust passage 26 communicating between the structural gases of the main 2. However, the trigger is limited; instead, the preferred embodiment is the present invention. If the valve is not opened, the trigger valve can have the function of entering the main airflow passage 11 before the valve stem 23 is buckled, and the trigger valve including the solid-machine can be used. The invention utilizes: driving; ^=cylinder: 'fixed in the gun body 1' is not subject to high-pressure air, the middle of the 'milk cylinder 4' can have a ring-shaped top valve wall 41, the periphery of it 42 And at least the bottom layer through hole 43; a plurality of middle layer valve holes 42 in the inner side _ 44 to limit the middle layer valve hole 42 can only be ventilated by the gas body 4; and the bottom layer through hole 43 can be formed at the bottom of the cylinder 4 In addition, the bottom layer through hole 43 is directly opened on the cylinder wall surface 4 to be slidably provided with a shaft piston 45, and the gas red interior (4) negative layer oxygen chamber chamber 46 and an underlying cylinder chamber 47 are provided. On the wall = Ming 3 is in the shape of a circle, placed on the top of the gas red 4, the main air sighs the air washer 3a, and slides on the top of the body 1 - the ring surface 1331072 holes 51, 510 to connect the main air chamber And the main air passage. The outer wall of the main air valve 3 is integrally formed to form a rib ring 38 (shown in FIG. 1) to set a spring 61 at the top of the main air valve 3 and the main body 1 Between the inner walls; or a receiving surface 341 (shown in FIG. 4) is formed on the valve plug 34 for providing an equivalent spring 62, which can apply a downward downward to the main valve 3 and the valve plug 34. Based on the above, the state of use will be additionally explained in the configuration shown in Fig. 1. After the high pressure air which maintains a constant pressure is accumulated in the pressure collecting chamber 10, and the user does not press the valve stem 23 via the trigger 28 At the time (as shown in FIG. 5), the high pressure air in the pressure collecting chamber 10 drives the shuttle valve 22 to move up to close the intake passage 25 and open the exhaust passage 26, so that the high pressure air of the pressure collecting chamber 10 cannot pass through the trigger valve. The main air passage 11 and the main air chamber 35 are entered, and the main air valve 3 and the valve plug 34 are driven by the high pressure air in the pressure collecting chamber 10, and the spring 61 is assisted to be applied to the main air valve 3 (or the valve plug 34). On the downward thrust action relationship, the main air valve 3 and the valve plug 34 are moved downward, so that the valve pad 3b is pressed against the top valve wall 41 of the cylinder 4 to close the main air valve port 31 to block the set. The high pressure air in the pressure chamber 10 enters the passage of the top cylinder chamber 46, and the main air valve 3 opens an upper exhaust hole 15 at the top of the body 1 The remaining gas in the top cylinder chamber 46 is vented to the outside. In addition, when the valve stem 23 is buckled (as shown in FIG. 6), the shuttle valve 22 is driven downward by the high-pressure air in the pressure collecting chamber 10 to close the exhaust passage 26 and open the intake passage 25, and the guide set The high pressure air in the pressure chamber 10 continues to enter the main air chamber 35 through the main air passage 11, and generates a driving force from the bottom to the bottom of the valve plug 34 to drive the valve plug 34 to move the main air valve 3 synchronously upward. (Like, for example, 13311272, Figure 7); at this point, the upper vent 15 is closed by the top of the main gas 阙 3, and the main friend valve 3 opens the main vent 31' to guide the plenum 1 () ^ the top cylinder chamber 46 Inside the 'drive pinning piston:= 45 moves down to the position of the middle boring hole 42 (the high pressure air in the chamber 46 will be introduced from the middle layer of the hole 42 as shown in Fig. 8; the gas = pressure, and the IM is returned The lower limit of the bottom of the plug 45 is 16: when the valve (4) is released (as shown in Fig. 9), the air chamber si is replaced by the air passage 11 and the exhaust passage 268 to the outside to make the pressure in the chamber (7) The air and spring 61 drive the valve plug 34 to move down and reset in synchronization with the main air gap 3 to open the upper exhaust hole 15 and close the main air port 3, 1 of the main air valve 3, and the return air chamber 14 (4) presses air and self Bottom layer The hole 43 enters the bottom cylinder chamber 47, and the driving nail is lifted up by the piston 45 to return to the unpressed trigger state shown in Fig. 5, which is advantageous for repeated implementation. / Zongshang: Knowing the setting through the valve plug 'The downwardly extending main air valve receives the high pressure air driving position in the main air chamber, so the opening length of the retracted air passage can be specifically presented in the present invention to improve the opening and closing of the main air valve of the Koryo air drive.
