As mentioned in the previous paragraph, there are related industry breakthroughs in the shock absorber cushioning structure of the impact hammer. Among them, in order to enhance the rear seat vibration force generated when the impact hammer impact is absorbed, the industry has developed a The front and rear ends of the cylinder block and the outer tube are respectively provided with a double suspension suspension structure type of the shock absorber. 'This kind of conventional structure design is found in the actual use experience', compared with the traditional single Although the side shock absorber structure can achieve better rear seat vibration force 5 1358351 absorption buffer effect, the relative impact force of the inner piston of the impact hammer is also excessively absorbed, so that the impact strength of the impact hammer is obviously attenuated. The problem is that I have to pay attention to this. In view of the above-mentioned design and use of the conventional pneumatic hammer, the door inscription "How to develop an innovative structure that can be more ideal and practical" is the target and direction of the relevant industry. By. “In view of this, the inventor has been engaged in the manufacturing and development of related products for many years.” After the detailed design and careful evaluation of the above objectives, the invention has finally become practical.

Between the rear end of the seat 13 and the rear end wall 112 of the accommodating space 11 ,, the two-stage pre-type 4 rear shock absorber 30 includes an upper elastic buffer member 3 and a lower elastic buffer member. 32, wherein the at least the lower elastic buffer member 32 is pressed against the pre-compression by a pre-stressing member 33 by a predetermined degree of compression; the pre-compression member 33 of the embodiment The specific structure is as shown in the figures 2, 3, and 5, and includes a pressing plate 331 and a plurality of positioning bolts 332. The pressing plate 331 is abutted against the top end of the lower elastic buffering member 32, and the pressing plate 331 has a plurality of The through hole 333 α is provided for the positioning screw 332 to pass through, and the rear end of the sliding seat 13 of the main body 10 is provided with a plurality of screw holes 13 〇 for the positioning of the positioning bolts 332. Wherein, the two-stage pre-pressure type rear shock absorber 3 〇 upper elastic buffer member & can be made of elastic material (such as rubber, (four), etc.) - cylindrical block; or as shown in Figure 7 The upper elastic buffer member 31 is formed by a coil spring. Wherein, as shown in Figures 2, 3 and 4, the elastic buffer member 31 of the upper portion of the two-stage preloading rear shock absorber 30 can also be pressed by the second preloading member to a predetermined degree of compression. In the state of the pressure; the second pre-pressure member of the stomach may comprise a plurality of locating screws 42 which are provided with a plurality of perforations 43 for the positioning bolts 42 to pass through, the bottom of the positioning 8 42 % screw lock is located in the main screw hole 131 · 510, the rear end of the h seat 13 is set to 1, and the main body 1 〇 after the end wall 11? % #士^, Suining you ma concave is provided with a positioning groove 113 Λ疋The position of the B 113 should be equal to the positioning bolts > for the temple bolt 42 to be provided with the orientation of the card groove 114 乂t, the corresponding positioning bolt to make the meat, m production ^ shell. The clamp is fitted with the clamp, whereby the rotation between the lunar seat 13 and the main body 10 can be achieved. The main body 10 includes a handle 19, and the handle 19 can be a handle type, and is disposed on the main I# n T i 4 Λ q-shaped bending. The extension type; Χ, ... 1Q Μ the rear end is a cymbal ^ handle 19 rear end and is provided with a rear-mounted milk, and the joint 50 is used to introduce the air pressure. The description of the borrowing form is shown in Figure 4, and then enters the change of the group 15 after the gas, and the design is not composed of the above structure. The use of the present invention is as follows: The joint portion 50 guides the air flow passage 12, the module 15, and the flow head switching module is scheduled to switch the rapid adjustment of the tool head switching module 15 state as detailed. In the operation of the flushing device, the external air pressure W is transmitted through the handle 19 through the handle 19 to the rear end of the main body 10, and the pressure is introduced through the air intake duct 18. The air flow is switched inside the actuating cylinder 14, and in the process, the automatic 77 "丨L switching operation enables the air pressure path to be generated to cause the piston 17 in the operating cylinder 14 to move, thereby enabling the The tool head assembly 16 is configured to generate an expected impact vibration force; wherein the detailed operation principle of the gas flow cylinder 14 and the flow path configuration type are in the scope of the innovation protection of the present invention, which is not 1 358 351 and the present invention The core design of the impact key A is mainly to add the technical features of the two-stage pre-pressure type rear shock absorber 30, whereby the piston 17 of the actuating cylinder 14 = impact movement is opposite to the inner slide In the case of the rear seat force, at least the lower elastic buffer member 32 of the two-stage pre-pressure type rear shock absorber 3 is pre-compressed by the pre-stressing member 33 to exhibit a predetermined compression, so that the two-stage pre-dusting rear shock absorber The elasticity of 30 is the relative shape of the strange large shock absorber 20. , for the free floating of the inner slide (four), the spring balance of the front and rear shock absorbers is the same, that is, when the impact key causes the inner slide 13 to generate the rear seat force due to the impact action of the piston 17 'Using the two-stage pre-pressure rear shock absorber to obtain a relatively strong shock-absorbing cushioning effect, so that the impact strength of the piston 17 does not cause a slamming effect and the influence is too large, thereby making the impact key A It has a better impact and can also take advantage of the better shock absorption buffer. The advantages of the present invention are mainly ensured by the two-stage preloading that the elastic force is the self-contained phenomenon of the inner sliding seat. The seat is relatively strong and the rear seating force is relatively strong. The structural design of the two-stage pre-pressure rear shock absorber, the elastic force of the rear shock absorber is the state of being pre-stressed, and the constant is greater than the relative state of the front shock absorber (not caused by the floating The rear shock absorber spring automatically balances the phase, thereby causing the impact hammer to be shocked by the piston impact action, and the shock absorber effect can be obtained by using the two-stage preloading shock absorber to make the piston impact The strength of the force does not sound, and thus the impact performance is improved and the practical progress of the fruit is achieved. 10 1358351 The above embodiments are disclosed by the specific terms, and the scope of the article is Technology:::之:::;= The invention of the invention ^ ^ a Xinshitian can change and modify the spirit of the invention to achieve the purpose of the effect, and this special side is more modified Should be covered in 1358351 f Brief description of the drawings] Fig. 1 Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7 • The preferred embodiment of the impact hammer of the present invention A perspective view of a preferred embodiment of the impact hammer of the present invention.
