The pressing member 51 is provided at the end of the rod body 53 so that the δ-Hui pressing member M is in a linked relationship with the rod body b. The elastic bobbin 52 sets the tendency of the pressing member 51 to be ready to the material member 54 at the time of the pressing of the pressing member μ and the guiding member. M396733 The rod body 53 has a first section 531, a second section 532 and a third section 533. The second section 532 is connected between the first section 531 and the third section 533, and the pressing member 51 Provided at the free end of the first segment 531, the outer diameter of the second segment is between the outer diameter of the first segment 531 and the outer diameter of the third segment 533, and outside the first segment 531 The diameter is larger than the outer diameter of the third segment 533, and the rod body is formed with a gas groove 534'. Please refer to FIG. 7A. The gas groove 534 is located at one end of the second segment 532 near the third segment 533. The height of the bottom surface is not higher than the third segment 533, and the height refers to the distance from the surface thereof to the central axis of the rod body 53, that is, the surface of the air groove 534 may be flush with the third segment 533, or The three segments 533 are trapped in the shaft. The guiding member 54 is rotatably received in the slot of the cylinder and is airtight against the bushing. The guiding member 54 is formed with an abutting hole 541 parallel to the axial direction. The shank 53 is movably inserted into the accommodating hole 541, and the first cover is disposed at one end of the accommodating hole 541 and abuts against the guiding member 54 to form a 7-1 outer diameter of the third segment 533.

The valve body 56 is formed with a valve hole 561 ′′. The valve hole 561 is sleeved in the second section 533 of the hainan. The first valve body 56 can be in a first position and a second position in the axial direction. During the movement, the first valve body 56 abuts against the second segment 532 when the first valve body 56 moves to the first position, the valve hole 561 has a smaller aperture than the contour of the third segment 533, so that the first valve body 56 and the first valve body 56 There is a gap between the three sections 533 for a small amount of gas to pass. The second valve body 57 is fixed to the free end of the third segment 533, and the second valve body 57 is abutted against the second valve body 57 when the first valve body 56 is moved to the second position, so that the second valve body 57 is first The valve bodies 56 are in an airtight state. Therefore, referring to FIG. 9 , when the elastic member 52 pushes the pressing member 51 away from the guiding member 54 , the first valve body 56 can simultaneously abut the second intermediate body 57 and the bushing 12 . At the same time, it is in a gas-tight state, so that the trigger valve group 5〇 is closed. At this time, the pressure gas system is pushed against the trigger valve group 5〇, so that the trigger valve group 5〇 is closed and not easy to open. The gap between the body 56 and the third segment 533 is small, so that the force of pushing the second valve body 57 by the gas is also small. Please refer to FIG. 1〇, the user only needs to secretly press the finger 5b. The urging member 51 pushes _ 53 ' to move the second valve body 57 with the rod body 53 , and the first % is pushed against the high pressure gas and still abuts against the bushing 12 , so that the gas can pass through the first valve body brother and the third The gap flow between segments 533 'makes the panel reading slightly open and releases the pressure of the high pressure mess. Please refer to the phase η. When the leader pushes in and presses the pressing member ', it only needs a small force to press, and then the dragon 53 can be moved again, so that the rod body 9 53 moves with the pressing member 51 to the second segment. The 532 abuts against the first valve body % to separate the first valve body 56 from the bushing 12, so that an opening for the gas flow can be generated between the first valve body 56 and the bushing 12 to further open the trigger valve block. By this, the steam-red system provided by this creation is integrally formed, and there is a trigger groove in the steam red molding. The county is equipped with a domain component, and no joints or gaps are formed in the various compartments of the cylinder, so that high-pressure gas can be prevented from flowing through the trigger valve. Air leakage occurs during the group to maintain the internal gas pressure for better working results. In addition, improving the airtightness of the bushing can also enable the creation of a more precise lathe valve block to be provided by the lathe valve block. The two-stage function allows the user to easily set up the lower unit. In addition, the production may be performed after the body and the bush body are die-cast, and the two vent holes are opened and the through hole is opened from the bottom end of the bushing or the extending portion, and the hole is directly drilled toward the body. Two gas passages or several air inlet holes, the trigger groove, gas passage and vent hole for the gas flowing through the steam (four) part are simple and concise, which can be easily produced for production, which is a proof of progress. /, [Simple description of the diagram] @睿 Figure 1 is a schematic diagram of the combination of this creation and other cylinder components.
