Description of the invention: [Technical field to which the invention belongs] The present invention particularly relates to a shock absorber for a pneumatic tool that uses a closed air chamber to provide a scale-type slow w 'air-to-air power. Device. Use to reduce operation [prior art] Pressing the 'pneumatic tool' operation mode can be approximate, whether linear reciprocating or rotating, and its rotation, the piece will generate a reaction force, and return 2 air contact time as the person During holding operation, 'that will cause discomfort, body = rate', in order to reduce the reaction force during operation ^ Niu Lowgong ^ Bay Patent Application No. 91218825 "Reciprocating 1 Pneumatic 1 Worker and 2 Figures' J Series Clothing" , Which is a member of the inside of the joint 10i of the main body 10i, the shock absorption straight cut groove 1 1 2 ^ Du internal surface tired said that there is a horizontal installation with a ventilator i 2 and J combined with gas Go up f, and then pass S】] 3 in the connecting part of the actuator 13 and the main body 10i; when the gas is self-injected: 1 0, 2 111, it will flow through the 1 1 slot control to guide the high-pressure air t change the idle piece of the fluorine valve 12 and further act as the air channel 1 3 2 and 3 of the side wall 3, when the gas 2 ί gas push shaft 1 3 1 push back backwards' · see the first, gas push shaft ί = 1 3 1 Push back to the valve blade shovel of 12 when it is close to the air valve 1 2 position: The air pushed in the moving rod 13 will make the rear end of the air valve, and push it to enter with two f 3 air turns The air of the moving rod 1 3 _ will be pushed and the air valve 1 3 2 ^ ^ will be used to make the valve valve 12 of the air valve 1 2 to move again to the lice machine to control the air valve 12 repeatedly. Switch to make the gas push 1235700 King of the Hand to dissipate the energy of the shock wave to extend the journey of the shock wave; however, the design is such that the vibration force generated by the author is 1. The transmission generated by the impact is transmitted to the actuator! 3 The power of 'P f on the body will be the component 1 1, the protective tube body i 4 and this / = 1 3 and the buffer 2 = method to effectively reduce the reaction_force parts are easily damaged due to vibration, and reduce the connection of the machine 3 . Buffer component! !! Set up cups ^ can be used. The processing is quite difficult, and the relative manufacturing costs are not in line with economic benefits. It ’s clear that the wind is coming back, and the present inventor has developed a Mao + work with his many years of research and design! Test, after continuous habitual shock absorption device Ϊίί. A secret-type shock-absorbing device to effectively improve the content of the invention. [Summary of the invention] Its main shock-absorbing device, ^ to the door prepared σ and buffer the sliding seat, and the slow-body chamber pushes the gas to slide into the 4 cavity ί Iittf forms a closed air chamber, and a replacement slide is installed in the buffer slide. i = ί This is used as a moving seat to act and take a wide range of forces. The vibration on the moving seat will be transmitted to the slow seat and back to compress the closed air. The indoor air, in turn, is provided with a secretive buffering effect by the breast milk, so as to effectively reduce the H of 1235700 to achieve the purpose of improving the comfort and efficiency of operation. The connection of the second sergeant's room = closed. Therefore, when the buffer slide recedes and compresses two or two, "smaller air hearing pressures' will result in a softer version. Another purpose of Ming is to provide a Pneumatic tool suction: 道 ίΐ = The rear end of the slide seat has another chamber, which is connected to the outside of the body by 逞, and the end of the suction channel is provided with a non-return in the body cavity and pushed forward by high-pressure gas. Can use the suction pipe to suck the outside air, and then form the first
