Abstract:
A device absorbs shock in a pneumatic tool containing a body, a cylinder, a valve unit, a piston member, plural buffer springs, and multiple fitting sleeves. The body includes a grip and a fitting sleeve fitted with the grip. The fitting sleeve has a chamber, a close face formed on a first end thereof, and an opening formed on a second end thereof. Each fitting sleeve is hollow and includes a limitation length forming along a hollow extending direction and shorter than a largest length. Multiple positioning sleeves are defined between a close face of the fitting sleeve and an abutting portion of the cylinder, and the multiple positioning sleeves are hollow so as to accommodate plural buffer springs. Because the limitation length is shorter than the largest length, the plural buffer springs extend out of the multiple positioning sleeves respectively.

Claim (Index 1):
A shock absorption device for a pneumatic tool, wherein a pneumatic tool comprises:\n a body including a grip and a fitting sleeve fitted with the grip, with the fitting sleeve having a chamber defined therein, a close face formed on a first end thereof, and an opening formed on a second end thereof; a cylinder slidably fixed in the chamber of the fitting sleeve and a part thereof extending out of the opening of the fitting sleeve, with the cylinder including a room defined therein and an abutting portion adjacent to the close face of the chamber of the fitting sleeve; a valve unit fixed between the room and the abutting portion of the cylinder; a piston member accommodated in the room of the body and sliding forward and backward along a movement axis; plural buffer springs mounted in the chamber of the fitting sleeve and abutting against the close face of the chamber of the fitting sleeve and the abutting portion of the cylinder, wherein a pressing direction of each buffer spring is parallel to the movement axis of the piston member, and plural elastic supporting points form between the close face and the abutting portion so that when the plural buffer springs do not press, a largest length forms; and multiple positioning sleeves is hollow and includes a limitation length forms along a hollow extending direction, the limitation length is shorter than the largest length, the multiple positioning sleeves are defined between the close face of the chamber of the fitting sleeve and the abutting portion of the sliding sleeve of the cylinder, and the multiple positioning sleeves are hollow so as to accommodate the plural buffer springs; hence the limitation length is shorter than the largest length, the plural buffer springs extend out of the multiple positioning sleeves respectively.
