One hammer piece, the strike that this hammer piece is placed in this hammer tube is indoor, and corresponding this two limited post of this hammer piece is concaved with a concave arc and a long concave arc respectively, this two limited post is arranged in this concave arc and long concave arc respectively, be provided with a perforation in these hammer piece central authorities, this perforation is formed with one respectively with respect to these concave arc both sides of this hammer piece and is the outstanding shock surface of radial outward, and should perforation by two shock surfaces towards this long concave arc direction convergent;
A connection piece, one section of this connector penetrate in the perforation of this hammer piece, and this connector is provided with an anvil piece corresponding to this two shock surface, and this connector section in addition is provided with a junction;
One output, this output are provided with a card that covers this strike chamber, and this output is provided with a joint portion that links this connecting portion towards this connector direction, and the distal process that this output differs from this joint portion goes out to establish an output shaft.
Described air tool hammering device is characterized in that: described connecting portion is made as a square column, and this joint portion correspondence is made as a square hole.
The utility model utilizes above-mentioned technological means, and in implementing the back because this hammer tube can be provided with two limited posts, and corresponding two limited posts are provided with a concave arc and a long concave arc in this hammer piece, be limited in this hammer tube for this hammer piece is ccontaining with convenient, and form the simple in structure of each element, and each interelement is installed easily, can effectively reduce manufacturing cost, and cooperate this connector to be linked to respectively in this output and the hammer piece, and reach the length that significantly shortens this output, it is long to reduce output, and the fatigue of materials problem that is produced can effectively increase the service life.
