The fifth cavity 32 is filled with inert gas. The sixth cavity 33 and the seventh cavity 34 are filled with damping oil.

[0030] A first connecting block 37 is fixedly connected to a surface of the fourth fixed plate 31 away from the third slide plate 30, a first limiting block 38 is fixedly connected to the first connecting block 37, a second limiting block 39 is sleeved on the outer circumferential surface of the first connecting block 37, and a first groove 36 is formed on an end of the third opening 35 away from the first connecting block 37.

[0031] The firing pin assembly includes a cushion block 24, a firing pin 25 and a first slide plate 26. One end of the first slide plate 26 is fixedly connected to the first sliding block 27, and the other end of the first slide plate 26 is fixedly connected to the firing pin 25. A first opening 21 is provided in the muzzle 20, and the firing pin 25 is slidably connected to the first opening 21. The cushion block 24 is fixedly connected to an end surface of the first cavity 12 close to the muzzle 20.

[0032] It is worth noting that the cushion block 24 is made of elastic material, an opening is formed in the cushion block 24 , and the striker 25 is slidably connected to the opening of the cushion block 24 .

[0033] The trigger assembly includes a first slider 44, a first push plate 47 and a contact piece 48. The first slider 44 is fixedly connected to the first push plate 47. The first push plate 47 is fixedly connected to the first elastic member 46. The first elastic member 46 is fixedly connected to the handle 15. A third groove 45 is provided on both sides of the first slider 44. The handle 15 is provided with a groove. The first slider 44 is slidably connected to the groove. A second groove 40 is provided on the outer circular surface of the second cavity 14. An electric telescopic baffle 41 is fixedly connected in the second groove 40. The electric telescopic baffle 41 is electrically connected to the contact piece 48.

[0034] It is worth noting that the electric telescopic baffle 41 is a prior art, and the setting of the third slot 45 can be used.

[0035] A second elastic member 51 is disposed in the fourth cavity 19 , one end of the second elastic member 51 is fixedly connected to an end wall of the fourth cavity 19 , and the other end of the second elastic member 51 is fixedly connected to a second push plate 50 , which is slidably connected to the fourth cavity 19 .

[0036] A guide tube 42 is provided on the side of the handle 15 close to the gun body 11, and a guide groove 43 is opened in the guide tube 42. The guide groove 43 connects the second cavity 14 and the third cavity 16. An opening is opened on the handle 15, and an inflation tube 22 is fixedly connected in the opening. A second opening 23 is opened in the inflation tube 22, and the second opening 23 is used to connect the boosting mechanism. The boosting mechanism is the existing technology.

[0037] When the present scheme is used to fire the pneumatic nails of the pneumatic nail gun, first, the second opening 23 is connected to the boosting mechanism, and the boosting mechanism boosts the pressure in the third cavity 16 through the second opening 23, and the air pressure enters the second cavity 14 through the guide groove 43, thereby increasing the air pressure on the side of the second slide plate 29 away from the first sliding cylinder 28.

[0038] Then, the operator holds the handle 15 and moves the first push plate 47 with his fingers, pushing the first push plate 47 toward the handle 15, and the first push plate 47 separates from the contact piece 48. The contact piece 48 sends an electrical signal to the electric telescopic baffle 41, and the electric telescopic baffle 41 contracts, releasing the limit on the second slide plate 29. Since the air pressure in the second cavity 14 on the side of the second slide plate 29 away from the first sliding cylinder 28 is much greater than the air pressure on the side of the second slide plate 29 close to the first sliding cylinder 28, the second slide plate 29 slides toward the side close to the first sliding cylinder 28.

[0039] Finally, the second slide plate 29 pushes the first slide plate 26 to slide toward the gun nozzle 20 through the first sliding cylinder 28 and the first sliding block 27. The first slide plate 26 drives the firing pin 25 to slide toward the gun nozzle 20, and the firing pin 25 quickly pushes out the nail that enters the first opening 21 in the fourth cavity 19.

[0040] When the second slide plate 29 slides toward the side close to the first sliding cylinder 28, the first sliding block 27 compresses the fifth cavity 32, and the fifth cavity 32 pushes the third slide plate 30 toward the fourth fixed plate 31. The third slide plate 30 allows the damping oil in the sixth cavity 33 to enter the seventh cavity 34 through the third opening 35, and compresses the damping oil, thereby increasing the damping between the first sliding block 27 and the first sliding cylinder 28, thereby achieving the purpose of improving the air pressure stability in the second cavity 14.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
