of the valve plug 21 and the wall 21 of the inter-check valve 21 below the stop air ring 212, and can communicate with the top of the valve plug 21 and the outside atmosphere. The air pressure causes the valve pin 21 to be reciprocally displaced by the connecting rod 8. Based on the above, the state of use of the present invention will be described with reference to Figs. 9 to 15 as follows: The S user wants to use the nail to punch through one of the perforations 9〇1 of the workpiece 9 to nail the workpiece 90 to another processing. When the object 91 is on, the nail is first exposed in the perforation 9 and the tip of the nail 9 outside the knocking seat 41 is implanted into the perforation 9〇1 (as shown in FIG. 7), and is in contact with the surface of the workpiece 91. When the tapping seat 41 does not touch the surface of the workpiece 90; when the user presses the trigger 31 (as shown in FIG. 9), the trigger 31 first touches the buckle portion 51 of the inner reed 5 to make the inner spring gas 5/^ Pushing the urging portion 52 against the urging end 82' of the connecting rod 8 causes the connecting rod 8 to drive the valve check 21 and the safety slider 4 to move downward, causing the knocking seat 41 at the bottom end of the safety slider 4 to move down to the workpiece 91. Receiving a workpiece 9 〇 surface stop (as shown in FIG. 7a) within a predetermined height Η range, the predictive Η 包括 includes a workpiece 9 〇 thickness or a perforation 901 depth suitable for the nail plucking, the first and second The relative positions between the air holes 221, 222 and the upper and middle air rings 211, 212 are designed to match the preset height η 13 1373401; thus, the tip of the nail 9 of FIG. 7a is The relative distance between the bottom surfaces of the seats 41 reflects the depth of the perforations 901. When the depth of the perforations 9〇1 meets the preset height Η, the valve plug 21 drives the upper air ring 211 to the first air hole 221 ( Cooperating with FIG. 6a), and driving the stop gas ring 212 to the lower side of the second air hole 222 to communicate the air path between the air inlet 201, the first air hole 221, the first air hole 222 and the air outlet 202, opening the first The second air passages 111, 112 are connected; then, the trigger 31 will immediately actuate the valve stem 32 to drive the trigger valve 3 to open, thereby causing the high pressure air in the pressure collecting chamber 1 to pass through the intake passage 33 and the first air. The road m and the air inlet hole 2 (H 'the first air hole 22, the second air hole 222 and the air outlet hole 202 enter the second air path 112, and are introduced into the main air chamber 61 of the main air valve 6 (as shown in FIG. 1A). The main air valve 6 is driven to open the top of the cylinder 7, and the high pressure air of the pressure collecting chamber 10 is caused to enter the upper cylinder chamber 71. The driving piston 70 drives the hammer rod 701 to move the firing nail member 9, so that the nail member 9 is driven into the self-piercing 901. The workpiece 91 is mounted on the workpiece 91 (as shown in FIG. 8) to fix the workpiece 90. According to the present invention, the present invention can be used for nailing. The slider 4 and the knocker seat 41 react to the 'extent or 'perforated 901 depth of the workpiece 90 to be nailed, and then sense the reaction height of the safety slider/rod 4 via the valve plug 21 of the control-φ valve 2 to open the valve The high-pressure air in the main airflow path 11 is driven to drive the nail. When the user releases the valve rod 32 by loosening the trigger 31 (as shown in FIG. u), the high-pressure air in the pressure collecting chamber 10 drives the trigger valve 3 to close the valve. The fluorine inlet passage 33 is closed and the exhaust passage 34 is opened, so that the high pressure air in the pressure collecting chamber 1 cannot continuously enter the main air passage 11, the control valve 2 and the main air chamber 61 via the trigger valve 3, and the main air chamber 61, The main airflow path u and the high-pressure air in the control valve 2 are discharged to the outside through the exhaust passage 34 (as shown in FIG. 12), so that the high-pressure air of the pressure collecting chamber 10 drives the main air valve 6 to close the top of the cylinder 7, prompting 1373401 The piston 70 is moved up and down; at the same time, the release trigger 31 releases the buckle portion 51 of the inner reed 5, so that the pushing portion 52 of the inner reed 5 releases the force receiving end 82 of the connecting rod 8, so that the spring at the bottom end of the plucking body 1 is caused. 42 (shown in FIG. 3) driving the safety slider 4, the knocking seat 41, the connecting rod 8 and the valve plug 21 to move up and reset, thereby blocking the first and second Communicating passage 111, 112 (FIG. 2 complex). In addition, if the thickness of the workpiece 90 or the depth of the perforation 9〇1 is greater than the preset height ,, the stroke of the safety slider 4 and the valve plug 21 can be shortened; at this time, the user pressing the trigger 31 will first touch the inside. The reed 5 pushes the link 8 down (as shown in FIG. 13), causing the connecting rod 8 to move the valve plug 21 and the safety slider 4 downward, causing the knocking seat 41 at the bottom end of the safety slider 4 to move down to the processing. The position of the preset height Η range is not above the object 91; thus, the valve pin 21 drives the upper air ring 211 above the first air hole 221 (shown in FIG. 6a), and drives the air ring 212 to the first stop. Between the second air holes 221, 222, the first and second air paths 111, 112 are blocked; then, the trigger 31 will still open the trigger valve 3 to open the valve, causing the pressure chamber 1 to be inside. The high-pressure air is guided to the air inlet hole 201 of the control valve 2 via the intake passage 33 and the first air passage 111, but since the control valve 2 has blocked the first and second air passages in and in, the brake can be braked. The nail member 9 is fired. In addition, if the thickness of the workpiece 90 or the depth of the through hole 901 is less than the predetermined height ,, the stroke of the safety slide bar 6 and the valve pin 21 can be increased; at this time, the user presses the trigger 31 to first touch the inner spring. The piece 5 pushes the link 8 down (as shown in FIG. 14) to cause the connecting rod 8 to move the valve pin 21 and the safety slider 4 downward, causing the knocking seat 41 at the bottom end of the safety slider 4 to move down to the workpiece. The position above the preset height Η range is 91; thus, the valve pin 21 drives the upper air ring 211 below the first air hole 221, and drives the stop air ring 212 15 1373401 below the second air hole 222 to block The first and second air passages U1, 112 are in communication; subsequently, the trigger 31 still drives the trigger valve 3 to open the valve, thereby causing the compressed air in the pressure collecting chamber 10 to pass through the intake passage 33 and the first air passage m. Guided to the air inlet hole 201 of the control valve 2, and into the guide groove 220 at the top of the valve plug 21 via the first air hole 221, to drive the sliding sleeve 22 to move upward against the spring 23 force (as shown in FIG. 15), resulting in The upper and middle air rings 2u and 2u are located below the first air hole 222' and the sliding sleeve 22 is moved upward to drive the lower air ring 225 to the air outlet 202. Side, to block the second hole 222 and the second air passage ιΐ2 • communicating, and thus brake the staple to grab the staple firing member 9. If the user only nails the nail member 9 to the workpiece 91, the knocking seat 41 is moved down to a position above the workpiece 91 beyond the preset height , range, or the user accidentally touches the trigger 31, causing the knocking seat 41 to be lowered. Moving to the position above the upper reading 91 beyond the preset height Η range, the sliding sleeve 22 is driven up, and the upper and middle air ring 21 is formed below the second air hole 222, and the lower air bearing 225 is located. The state above the air hole 202 is based on the brake nail rushing the nail member 9. It can be seen from the above that the valve pin 21 of the present invention can be directly driven by the inner spring of the trigger 8 receiving the trigger, and the displacement into the control valve 2 can drive the position of the interstitial air control nail to slam the nail, and The interlocking safety slider 4 is displaced to the top of the workpiece 90 to improve the stability of the nail control, and the sliding sleeve and the valve plug 21 are driven by high-pressure air, which can also improve the stability of the nail control; The sliding sleeve 22, the valve plug 21 and the gas path can achieve the benefit of simplifying the complexity of the assembly and the air circuit configuration. Referring to FIG. 16, a cross-sectional view of a second embodiment of the present invention is disclosed.
