Note.
Description of the drawings
Fig. 1 is a kind of structural representation of the Pneumatic portable of the invention with line mark rifle.
Specific embodiment
Technical scheme is described in further detail with reference to Figure of description.
As shown in figure 1, a kind of Pneumatic portable of the invention includes gun body 1, cylinder piston 2, trigger 3, hits with line mark rifle
Pin 4, obform guide rail 5 and steel character head 6.
Gun body 1 is " ┐ " shape, and " ┐ " top is the body of a gun, and " ┐ " bottom is pikestaff.The body of a gun is divided into two chambers vertically.Tail
Portion's chamber is control chamber, and control within the chamber is provided with control piston 8, and control piston 8 is divided into left control chamber by chamber is controlled
With right control chamber.The cylinder body of cylinder is located at the stem within the chamber of the body of a gun, and cylinder body is fixedly connected with the body of a gun, and cylinder body periphery and rifle
Space between body inner circumferential constitutes backhaul air storage chamber, and inner chamber of cylinder block is docked with control chamber.
Multiple return-air through holes and multiple air through hole are provided with cylinder body, multiple return-air through holes and multiple air through hole are along cylinder
