Improved nail pushing chamber for pneumatic nail shooter

The utility model relates to an innovated nail pushing chamber for a pneumatic nail shooter, particularly a nail pushing chamber which has double nail feeding slots where a long range nail and a short range nail can be conveniently stored. Plates at the two sides of the nail pushing chamber are partitioned, a gap is arranged between the plates. The range nails can be placed into the gap, and the head end of the range nails bulges at the outside of the two side plates. The center of the side face within the two side plates is oppositely provided with a longitudinal concave groove into which the head end of the range nail whose length is shorter is wedged, and the range nail can slide in the longitudinal concave groove. The nailing groove of the bottom plate of a shooter nozzle is similarly provided with a concave hole which is opposite to the two concave grooves, the range nail can pass through the concave hole, and the range nail can be pushed out by a striking needle.
