The two-stage pre-pressure rear shock absorber 30 is disposed behind the slide 13 of the main body 1〇. The two-stage pre-type rear shock absorber 30 between the end and the rear end wall 1] 2 of the accommodating space 11 包括 includes an upper elastic buffer member 31 and a lower elastic buffer member 32 stacked on each other, wherein The at least the lower elastic buffer member 32 is pressed by the φ-pre-mechanism member 33 to a predetermined degree of pre-stressing state; the pre-stressing member 33 of the present embodiment is specifically configured as shown in the second, third, and fifth embodiments. As shown, it comprises a pressing plate 331 and a plurality of positioning bolts 2, wherein the pressing plate 331 is pressed against the top end of the lower elastic buffering piece and the pressing plate 331 is provided with a plurality of perforations 333 for the positioning bolts 3 to be made. In the wearing group, 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. The elastic buffer member 31 of the upper portion of the two-stage pre-pressure rear shock absorber 30 may be a cylindrical block made of an elastic material (such as rubber, silicone, etc.); or the upper elastic portion as shown in FIG. The cushioning member 31B is composed of 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 pre-pressure rear shock absorber 30 can also be pressed by a second pre-compression member 40 to a predetermined degree of compression. The second pre-stressing member 40 may include a pressing edge piece 41 and a plurality of positioning bolts 42. The pressing edge piece has a plurality of through holes 43 for the positioning bolts 42 to pass through. Positioning 201021982 (the bottom end of the bolt 42 is a screw hole (4) located at the end of the sliding body (4) of the main body 1 (); and the rear end wall 112 of the main body 10 is recessed with a positioning groove ιΐ3, the positioning (four) corresponding to The positioning bolt 42 is provided with a directional insertion groove ι 4 for the corresponding position; the t-bolt 42 bolt portion μ is matched, thereby enabling the orientation between the inner sliding seat 13 and the main body 10 to prevent internal slippage. The main body 10 includes a handle 19, and the handle 19 can be a rear handle type, and is disposed at the rear end of the main body 10 and has a meandering shape. Type, χ, the rear end of the handle 19 is combined with a rear-mounted air intake assembly 50 for introducing a pneumatic person. The structure of the structure is described as follows. The operation of the present invention is described as follows: Regarding the operation of the impact hammer, as far as the gas flow path is concerned, please refer to Fig. 4, and the external air pressure W is transmitted through the rear type. After the gas assembly 50 is introduced, the air intake passage 12 is disposed at the rear end of the main body 1 through the handle 19, and then the air pressure is introduced into the air flow switching module 15 through the air intake duct 18, and then enters the cylinder. Inside the body 14, during the process, the automatic shunt switching operation of the airflow switching module 15 is used to cause the air pressure path to generate a predetermined switching change state, so that the piston 17 in the operating cylinder 14 generates a rapid lifting forward and backward impact motion. The tool head 161 of the tool head assembly 16 can generate the expected impact vibration force; wherein the air flow switching module and the detailed operation principle of the working cylinder 14 and the flow channel configuration type are It is to be understood that the scope of the innovation to be protected by the present invention is not described in detail herein. 201021982 The core design of the impact hammer A of the present invention mainly consists in adding the two-stage pre-pressure type rear shock absorber. The technical feature of 30, whereby when the piston 17 in the body 14 generates an impact motion relative to the inner portion, the sliding seat 13 generates a recoil force, due to at least the two-stage preloading rear shock absorber 3〇 The lower elastic buffering member 3 2 is the preloading state of the predetermined degree of compression, so that the elastic state of the two-stage preloading rear shock absorber 30 is constant greater than the front = shock absorber The relative state of the device 20 does not cause the same phenomenon of the elastic balance of the rear and rear shock absorbers due to the free floating of the inner slide 13; that is, the impact hammer is caused by the impact of the piston 17 When the inner sliding seat 13 generates the recoil force, the shock absorber cushioning effect of the two-stage pre-pressure rear shock absorber 3 can be obtained, so that the impact strength of the piston 17 is not affected by the buffering effect. The big impact is to ensure that the impact key has better impact performance while at the same time taking into account the better shock absorption buffer effect. The two main sections of the invention ensure that the inner sliding is the same as the existing seat, and the advantage of being better shocked by the pre-compressed elastic force is that the rear seat is hard to avoid the shadow buffer effect. Because of the state, the strength of the inner slide can not be obtained due to the balance phase. The elastic force of the shock absorber after the design of the two-stage pre-pressure shock absorber is not limited by the pre-pressure limit. The relative state of the shock absorber (the spring force of the front and rear shock absorbers is automatically caused by the floating, thereby causing the impact hammer to be caused by the impact of the piston) to utilize the two-stage preloading shock absorber shock buffer effect. In order to make the impact of the piston sound, the impact performance can be improved and the practical progress can be achieved. 10 201021982 The above embodiments are disclosed to specifically illustrate the present invention, and although the description is by specific terms, when The scope of the invention is defined by the scope of the invention, and those skilled in the art can change and modify the spirit and principle of the invention to achieve the equivalent purpose.
