    Abstract: An impact hammer with pre-pressing damping and buffering effect includes a handle, outer barrel, air inlet, internal slide, actuating cylinder, air flow switching module and air inlet coupling portion. A front damper is assembled between the front end of the internal slide and the front end wall of the holding space and is characterized by a two-section pre-pressing rear damper assembled between the rear end of the internal slide and the rear end wall of the holding space. The two-section pre-pressing rear damper includes superposed upper and lower elastic buffers. At least the lower elastic buffer is pressed by a pre-pressing member to the preset degree. When the impact hammer yields recoil force under the impaction of the piston, the pre-pressing rear damper is employed to realize stronger buffering effect, so that the impact force is not much affected, thereby improving the impact efficiency and yielding excellent buffering effect.

    Abstract: A reciprocating pneumatic tool has a main tool body, a suspension internal slider and a rear damping spring. A front buffer air chamber is formed the main tool body and the suspension internal slider. A by-pass air supply passage is set into the cylinder wall of the main tool body and is arranged at interval with the hollow chamber along its extension. Both ends of the by-pass air supply passage have a first and a second venting end. The first venting end is linked to the air control valve chamber of the air pressure control module, and the second venting end is linked to the front buffer air chamber. Air pressure passing through air control valve chamber can be guided the through by-pass air supply passage, so the front buffer air chamber accumulates air pressure to generate a damping effect on the front end of the suspension internal slider.
