The specific embodiment

Illustrate by Fig. 1, the utility model is mainly by ailing machine 10, head 11, cylinder 20, piston 24, bolster 30 is formed, and wherein, is provided with a cylinder 20 in the head 11, in the cylinder not end wall 212 centers one through hole 23 is arranged, inwall 211 is provided with a plurality of pores 214 with cylinder 20 exterior, and axially movable piston 24 is housed in the cylinder 20, and striker 25 is contained on the piston 24 vertically, striker 25 can pass through hole 23 when piston 24 moved, bolster 30 is to be made of two or more unlike materials, and is installed in piston 24 and not between the end wall 212, and striker 25 can pass bolster 30.

By figure also as can be known, ailing machine 10 comprises head 11, is provided with a room 12 in it, is provided with a cylinder 20 in the room 12, and head 11 apical margins and root edge are provided with several perforation 13 and communicate with room 12;

Cylinder 20, be provided with an air chamber 21 in it, the not end wall 212 that has inwall 211 in the air chamber 21 and link to each other, correspondence not end wall 212 has one and goes out power apparatus 22, the power source that wherein goes out power apparatus 22 can be compressed air or gas, is provided with a ring that links to each other at

inwall

211 and 212 of end walls not and encloses portion 213, and ring encloses portion 213 and forms a drop with inwall 211, end wall 212 central authorities are not provided with a through hole 23, and inwall 211 is provided with a plurality of pores 214 and is communicated with room 12;

Piston 24, axially back and forth in air chamber 21, and piston 24 can be gone out under the effect of power apparatus 22, and produces strong impact;
