The body circumference of staple bolt still evenly is equipped with a plurality of openings not only in order to subtract heavy, and it is convenient still to make things convenient for the shaping of staple bolt.

The further improvement is that: the outer surface of the cylinder body is axially provided with a plurality of longitudinal reinforcing ribs, and the outer surface of the cylinder body is also provided with a plurality of circumferential reinforcing ribs in the axial diameter.

The arrangement of the longitudinal reinforcing ribs and the circumferential reinforcing ribs ensures the strength of the air cylinder.

The further improvement is that: the cylinder body is formed by injection molding or compression molding.

Has the advantages that:

the utility model discloses utilize light-weighted easy shaping, light in weight, the assembly is easy, and it is also very convenient to maintain and change.
