Detailed Description

The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.

The chisel-adapted pneumatic tool 10 of the present embodiment, as shown in fig. 1, fig. 3, and fig. 5, includes a body 11, a cylinder 14, and a stopper 16, wherein the cylinder 14 is mounted on the body 11, and the stopper 16 is mounted at the front end of the cylinder 14 in an internal and external thread manner, wherein the stopper 16 is formed by an annular body, and has a cavity 160 therein, including an opening 162, an accommodating cavity 163, and a fastening cavity 164.

As shown in FIGS. 3 and 5, the stopper 16 has a length L from the front end to the rear end, ranging from 40 to 45mm, and a circular hole 165.1 of the inlet 165, whose center is at a distance g from the opening 162 of the stopper 16, ranges from 12 to 13 mm. The inlet 165 of the stopper 16 comprises a portion of a circular aperture 165.1 having a diameter f and a dimension in the range 14-16 mm.

In fig. 2 and 3, the stopper 16 has a central axis a on the outside and a diameter d on the outside, which ranges from 35 to 40 mm. The front end of the stopper 16 has an opening 162 in the shape of a circular hole having a diameter a in the range of 13-16 mm. The fastening cavity 164 of the stopper 16 has a diameter c in the range of 25-30mm and is internally threaded 161. The receiving cavity 163 of the stop block 16 has a diameter e in the range of 18-20mm and is located between the opening 162 and the fastening cavity 164. The stopper 16 has an inlet 165 that extends from the outer circumference into the cavity 160 and intersects the opening 162, the receiving cavity 163, and the fastening cavity 164.

As shown in FIG. 2 and FIG. 6, the inlet 165 of the stopper 16 includes two parallel surfaces 165.2 intersecting the opening 162, the parallel surfaces 165.2 being separated by a distance b in the range of 13-14 mm. The plug part 171 of the mounting device 17 penetrates from the inlet 165 of the limit block 16 to enter the accommodating cavity 163 of the cavity 160, meanwhile, the plug part 171 penetrates through the guide part 141 of the cylinder 14, and then the internal thread 161 of the limit block 16 is screwed on the external thread 140 of the cylinder 14, so that the assembling steps of the cylinder 14, the limit block 16 and the mounting device 17 are completed.
