Description of the Invention: [Technical Field] The present invention relates to a movable cylinder driving pneumatic circuit of a nail grab, in particular to a configuration technique of a high-pressure air passage between a trigger valve and a movable cylinder, and the trigger valve It is a technique for opening the valve and guiding the high-pressure air to drive the cylinder up when the valve stem is pressed. [Prior Art] A nail gun equipped with a movable cylinder in the prior art can be found in the cases of U.S. Patent No. 4,784,308, No. 4,319,705 and No. 4,294,391, which disclose a movable cylinder in the body, above the cylinder. Separating and arranging a valve, the main airflow passage is also provided in the body, and is connected between the upper air chamber of the head valve and the first-trigger valve, and the trigger valve is a driving pressure-relieving method to drive the nailing. When the trigger valve stem is not buckled, the trigger valve guides the high-pressure air to be introduced into the upper air chamber through the main air flow passage to drive the head valve to push down the cylinder downward to close the opening between the head valve and the cylinder; When the boring machine is used, the machine valve 镰 镰 镰 镰 镰 镰 镰 镰 镰 镰 镰 镰 镰 镰 镰 镰 镰 镰 镰 镰 镰 镰 镰 镰 镰 镰 镰 镰 镰 镰 镰 镰 镰 镰 镰 镰 镰 镰 镰 镰 镰 镰 镰 镰 镰In order to open the valve port between the head valve and the cylinder, the high-pressure air is guided into the cylinder to drive the nail. However, the shortcoming is that it needs to be configured at the same time as the movable gas red, and the lack of it has caused the problem that the air passage in the body is too complicated and the number of components is too large, which is not conducive to the production and assembly of the nail. - In addition to the above, a nail gun is also known in the prior art, which is provided with a trigger valve for driving a nail in a driving mode, and a fixed cylinder; taking the techniques of National Patent Publication No. 439630 and No. 1263565 as an example When the pressure is 5 1327098 = rod, the valve can be opened and the high-pressure two-rolling in the gun body is directly guided by the main air flow passage to directly drive the nail under the nail in the cylinder. i You stomach: the configuration of the valve and its driving gas path 'only its shortcoming is that the T gas rate can be too slow' to detract from the high pressure air use only for smaller nails, but not suitable; medium and large nails, so Still to be improved.

Further, the trigger valve 2 is formed with an intake passage 25 communicating between the surge chamber 10 and the main gas passage 11, and an exhaust passage 26 communicating between the main air passage 11 and the outside atmosphere. However, the structure of the above-mentioned trigger valve 2 is only a preferred embodiment. In fact, the present invention is not limited thereby; in other words, the trigger valve has a valve that can be opened to guide the valve when the valve stem 23 is pressed. The function of the air entering the main air passage 11 and the trigger valve including the same function as in the prior art can be utilized for the present invention. In particular, the present invention is based on the function of the above-mentioned trigger valve 2 to construct a driving air path of a movable cylinder 4, which is formed on the outer wall of the cylinder 4 to form a ring 41 (shown in FIG. 1) on the outer ring wall. A gas stop washer 41a is provided to slide the ring 41 on an annular wall surface 12 in the body 1. The top of the ring 41 has a gas groove 42 for continuously collecting the high-pressure air in the collecting chamber 10, and a bottom portion of the ring 41 forms a main gas chamber 43 communicating with the inlet and exhaust passages 25, 26. In a more specific implementation, the air groove 42 is formed in an annular cylinder liner 5 (shown in Fig. 1), and the cylinder liner 5 is fixed to the inner wall of the gun body 1 at the periphery of the cylinder 4. In addition, the cylinder liner 5 is provided with at least one through hole 52 for guiding the high pressure air of the main air chamber 10 to continuously enter the pressure collection in the air tank 42.

As an annular cylinder surface for guiding. In addition, the middle portion of the cylinder 4 is provided with a plurality of intermediate valve holes 46, which are restricted by one valve ring 47 to be unidirectionally exhausted from the inside and the outside of the cylinder 4; at least one lower through hole is provided on the inner wall of the gun body 1 at the bottom of the cylinder 4. 48, and a piston 6 for the nail is slid in the cylinder 4; at the same time, a spring 8 is disposed between the cylinder sleeve 5 and the ring 41, and the high-pressure air driving cylinder 4 in the auxiliary air tank 42 is maintained in the downward position. Furthermore, a spacer ring 7 (shown in FIG. 1) is disposed between the outer wall of the cylinder 4 at the bottom of the ring 41 and the inner wall of the grab ring, and a gas-insertion washer 7a, 7b is arranged on the inner and outer wall surfaces of the spacer ring to make the main The gas chamber 43 is formed at intervals between the top of the spacer ring 7 and the bottom of the ring 41.

Shift the nail. When the piston 6 moves down to the position of the intermediate valve hole 46 (as shown in FIG. 5), the high pressure air at the top of the piston 6 is introduced into the return air chamber 14 from the middle valve hole 46, and the piston 6 is moved down to the bottom position. The lower vent 16 is then closed. When the valve stem 23 is released (as shown in FIG. 6), the high-pressure air in the main air chamber 43 is discharged to the outside through the main air passage 11 and the exhaust passage 26 to drive the high-pressure air and the spring 8 in the air tank 42. The cylinder 4 is moved down to reset the upper exhaust hole 15 and the main air valve 44 is closed to the main air valve port 50, and the high pressure air in the return air chamber 14 enters the cylinder 4 from the bottom through hole 48 to drive the nail. The piston 6 is moved up and reset to return to the unpressed 1327098 trigger state shown in Figure 2, which is advantageous for repeated implementation.
