Furthermore, a: another oil seal 2 is disposed between the inner wall edges of the two accommodation chambers 3 3 , and a M312401 long groove 520 is formed in the cup body 52 and formed in the long groove ς 9n . There is a through hole 521, so that the long groove 520 can communicate with the outer side of the rod body 52 through the through hole 52, and the cover seat 5 2 2 is disposed at the free end of the long groove 5 2 (10), and the cover seat 5 is provided. 2 __ has a communication hole 5 2 3, Qiande _ 2 near the upper end of the outer side via the communication hole 5 2 λ gb LZ 3 / now enters the long groove 5 2 0 and then flows to the outside of the lower middle end of the rod 5; The elastic body 5 5 may be disposed between the ring body and the rod body 51 or the second accommodating chamber 3; and the above-mentioned rod body 52 and the second accommodating chamber may also be provided; And the rod 2 can also be used for the firing of the bumper 9-end. Since the rod body 5 2 already located in the sub-switch group 5 is assembled on the rod body 52 due to the pushing action of the elastic body. The other oil seal 59 does not block on the axial portion 5丄2 of the movable body 51, but forms the second accommodation chamber 3 3, the communication hole 5 2 3 of the rod body 5 2 , the long groove 5 2 〇, and the through Hole 5 2 ! is open to the outside of the body 3 State (ie, the sub-switch group 5 is normally open, as shown in the fourth figure). At this time, the bumper 9 is first pressed to move up to the bottom edge of the rod body 5 2 (ie, the rod body 5 2 does not After the illusion is moved, the trigger 9 9 is pressed to force the main shaft 4 of the main _ group 4 to move upwards, and the stop ring 4 4 that has been placed on the shaft 4 2 is followed up. Moving until the leak stop ring 4 4 passes through the other through hole 4 2 2 of the limiting body 4 2 and stays between the through hole 4 2 and the other through hole 4 2 2 and is located at the lower end of the shaft 41 The oil seal 45 can also be squeezed into the space portion 4 2 限 of the limiting body 42; in other words, the through hole 4 2 and the other through hole 4 2 2 are not connected, and the through hole 4 2 2 and the re-opening hole 4 2 3 form a connected state (as shown in the fourth figure), so that the gas of the main airway 3 (four) cannot flow to the population of the upper airway 34 by the main group 4 4 (10), which will cause The gas in the upper air M312401 channel 3 4 flows backward through the other through hole 4 2 2 of the main switch group 4 and the other through hole 4 2 3, and then flows into the second accommodation chamber 3 3 , and then passes through the instant. Sub-switch group 5 (ie already located in the shaft 52 The upper oil seal 59 is no longer blocked on the axial portion 512 of the movable body 51) and has been opened to directly discharge the gas to the outside (as shown in the fourth figure). Under the action of the gas pressure in the air passage 34 and less than the main air passage 30, the pressure in the main air passage 30 can be quickly filled in the air chamber 3 after the top pressure seat 6 is pushed upward.丄 and cylinder 7 (refers to have been placed in the upper edge of the piston group 8 in the cylinder 7), and began to quickly push the piston group 8 down to the bottom to be in a fired state; at this time, t fired to The _ before the bottom, because the upper edge of the piston group 8 has passed through the air hole 7 G of the cylinder 7, the part of the gas that has been filled in the gas chamber 3 1 (that is, the gas supplied by the main air passage 3 而) first flowing from the air hole 70 of the cylinder 7 in the direction of the air passage 3 5, and then flowing through the air passage 3 5 into the second valley chamber 3 3 ' and can continue to be located in the second housing chamber In the 3 3, the trunk 5 of the sub-switch group 5 is moved up to the fixed position and no longer moves, even if the piston 8 hits the needle 8 After the rebound force is formed to force the bumper 9 to return to the original position (as shown in the fifth figure), after the bumper 9 is pressed again, the position of the rod 52 of the sub-switch group 5 cannot be changed to k'. After the top pressure seat 6 is opened, the gas in the main air passage 3 is immediately passed through the air passage 31 and then passed through the air passage 35 to ensure the position of the shaft 5 2 of the sub-switch group 5 after being moved. On the other hand, when the operation sequence is not correct, the trigger switch 7 is pressed first, and then the main switch is forced, and the shaft 4 of the shaft 4 and the stop ring 4 4 thereon are moved upward, and A leak-stop ring 4 4 is formed to pass through the other through-hole 4 2 2 of the limiting body 4 2 and stays between the through-hole 4 21 and the other-through 11 M312401 • ' the hole 4 2 2 and is placed on the shaft The oil seal 45 at the lower end of the 41 can also be squeezed into the space portion 4 2 0 of the limiting body 42; therefore, the local gas originally located in the upper air passage 34 is passed through the inlet 3 4 0, the limiting body 4 2 The other through hole 4 2 2, the other through hole 4 2 3 and the air inlet 3 3 0 then flow into the second accommodating chamber 3 3 . At this time, although the sub-switch group 5 is normally open, Grouped The cover seat 5 2 2 disposed on the end of the long groove 5 2 0 of the rod body 5 2 of the sub-switch group 5 has a closed end, and the cover seat 52 2 and the long groove 520 have a communication hole formed at the side thereof. 523 (as shown in the sixth figure), therefore, the gas which has been φ into the first accommodating chamber 3 3 is pressed against the cover 5 2 2 on the end of the rod body 5 2, and the cover seat 5 2 2 is forced. The rod body 52 is driven to move downward until the other oil seal 59 that has been assembled on the trunk body 5 2 passes through the guide hole 5 1 3 and is indeed blocked on the shaft core portion 512 of the rod body 5 2 . The gas that has flowed through the through hole 5 21 of the rod body 5 2 is refilled into the small air chamber 54 through the guide hole 513 until the movable body 5! is pushed up and the rod body 5 2 is moved upward. Until the predetermined highest position (as shown in the seventh figure), the gas that has flowed into the second housing chamber 3 3 is not completely discharged, in other words, φ is a value of the gas pressure in the upper air passage 34. It is slightly smaller, and the sum of the pressure after the fall and the rebound force of the spring 60 is also greater than the gas pressure value of the main air passage 3 ,, so that the pressing seat 61 cannot be pushed open. Who can not form a firing state. Please refer to the ninth figure, which is a further embodiment of the present invention. The main change is that the original air channel 35 is directly disposed on the lower side of the body 3 and changed to one end of the air passage 35. Connected to the cover 2 (i.e., above the presser seat 61), and the other end of the air passage 35 is connected to the second accommodation chamber 3 3 of the body 3, or the passway 3 5 12 M312401 air passages composed of the cover body 2, the body 3 and another hollow tube (not shown) are used to determine the main airway 3 by the movement of the seat 61. Whether the gas can be easily flowed through the air chamber 3 1 and then through the air passage 3 5 to the younger brother; the accommodation room 3 3; thus, the technical means and principles used are detailed in the above content Add a description, so it is not mentioned here, · As mentioned above, the narrative training __, indeed has an unprecedented _ new structure, Wei did not test any gall, and there is any similar production in the market.
