The invention discloses a cannon barrel axial line positioner which includes an axial line locating frame and an axial line extending rod. The axial line locating frame which is inside the barrel can be adjusted by a radial elevating adjustment mechanism to form a surface contact with the inner wall of the barrel, and the axial line locating frame and the inner wall the barrel are closely cooperated. The axial line extending rod is fixed outside the barrel via a positioning seat on the axial line locating frame, and is provided with mark points on the outer wall at intervals. The cannon barrel axial line positioner can be used for a precision test of a cannon adjustment angle. The precision test is carried out by directly positioning and then extending the cannon barrel axial line, and directly using the mark points arranged on an axial line extending part as reference points. The cannon barrel axial line positioner has an exquisite structure which can reduce errors between a mark point connecting line and an actual barrel axial line, thus improving the precision test of the cannon adjustment, and further guaranteeing the shooting precision.

The invention discloses a segment sleeve short back collapse automatic rifle, including a casing, a hand grip, a sight, firing mechanism components, rotating locked bolt impels counter components, etc. The invention is characterized in that the rifle also includes a segment sleeve transmission device, an air shock absorption device and a barrel disassembly and replace device. The segment sleeve transmission device consists of a sliding segment sleeve, a buffer spring and an energy regulation screw pair. The air shock absorption device consists of an air shock absorption piston, a barrel, the casing and a casing big nut. The barrel disassembly and replace device consists of the casing, the casing big nut, a barrel locating bolt and a demountable barrel. For a motion mass center of the segment sleeve transmission device completely coincides with a bore axis, the dynamic and recoil force transmission completely coincides with the bore axis. And the radial differentiation during the recoilforce transmission process is avoided and reduced to the utmost extend. The stability and the shoot precision of the barrel are guaranteed on fire. The invention has the advantages of large power bullet adaptability, high shoot precision, fast shooing speed, stable and reliable action, simple and reasonable structure, etc.
