Provided with step surface, two interplanars of step surface are connected by inclined-plane, and air-flow is oppressed on the step surface and inclined-plane, will drive valve
Core 32 is moved downward so that the first air admission hole of level 38 is connected with the air inlet of level second, and air-flow passes through the second air admission hole of level 40
Enter in the air admission hole 42 of level the 3rd, afterwards into the piston elevating movement acting in the inner chamber of cylinder body 18, taken offence in cylinder.Together
The second annular groove 58 also is provided with sample, above-mentioned the second air admission hole of level 40, its function is similar with the function of first annular groove 52,
Because valve element 32 is during lifting, the motion that rotates in a circumferential direction, if the connected mode of hole device to hole are might have, will
Cause to be aligned, air-flow can not be normal through, and by the way of annular groove device to hole, this problem is solved with regard to perfection.
When S2, exhaust
(a) the first air admission hole of level 38 and vertical first air admission hole 34 and first control air-source inflow hole 60 stop into
Gas；
(b) the second control air inlet of air-source inflow hole 62, promotes annular control block 48 to rise to extreme position, i.e., the annular is controlled
The top of clamp dog 48 is contacted with the top inner wall face of looping pit 46, and horizontal first through hole and the through hole of level second are blocked；
(b) piston falls under gravity, and the gas between piston and valve element 32 is pressurized to form gases at high pressure, itself and valve
The gas of the bottom of core 32 constitutes negative pressure, and now valve element 32 falls in the presence of the gases at high pressure and self gravitation so that exhaust
Hole 44 is connected with venthole 31, and air-flow is quickly discharged by steam vent 44.
More than, first waveform is hit by impact block 10 and occurs the waveform of pad 14 and second generation pad 16, two-way test is realized.
Additionally by cylinder and its internal structure, realize fast advance and retreat gas, greatly improve impact table top 4 lifting height and
Frequency.
Above example is only a kind of present invention embodiment therein, and it describes more specific and detailed, but can not
Therefore it is interpreted as the limitation to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art,
Without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the protection model of the present invention
Enclose.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
