For achieving the above object, the utility model is by the following technical solutions:
Modular cylinder described in the utility model, comprise the front cylinder barrel and rear cylinder barrel that arrange vertically, described front cylinder barrel is connected by intermediate mass with described rear cylinder barrel, the front end of described front cylinder barrel is provided with protecgulum, the rear end of described rear cylinder barrel is provided with bonnet, secondary piston is provided with in described front cylinder barrel, described secondary piston is fixedly connected with secondary piston bar, the end of described secondary piston bar is passed described protecgulum and is stretched out in the outside of described front cylinder barrel, back piston is provided with in described rear cylinder barrel, described back piston is fixedly connected with back piston bar, described secondary piston bar is provided with the shaft through-hole with described back piston bar corresponding matching, the end of described back piston bar is successively through described intermediate mass, described secondary piston and described shaft through-hole.
Further, between described back piston bar and described secondary piston bar, be provided with clutch shaft bearing, between described protecgulum and described secondary piston bar, be provided with the second bearing.
Further, all dust ring is embedded with between described protecgulum and described secondary piston bar, between described secondary piston bar and described back piston bar.
Further, described secondary piston is provided with the bumper with described intermediate mass corresponding matching.
Further, described bonnet is provided with the gas damping mechanism coordinated with described back piston, the inner side of described bonnet is shaping is provided with groove, described back piston is provided with the extension with described groove fit, the sidewall of described groove is provided with the cushion pad matched with described extension, and described groove and described cushion pad coordinate the described gas damping mechanism of formation.
The beneficial effects of the utility model are: the utility model is serial combination type cylinder, exert oneself during work larger, by arranging the shaft through-hole with back piston bar corresponding matching in secondary piston bar, the end of back piston bar is successively through intermediate mass, secondary piston and shaft through-hole, compared with prior art, the utility model axial dimension arranges less, effectively reduce the overall volume of cylinder body, thus save installation footprint, save material, reduce processing cost, and, owing to arranging shaft through-hole in secondary piston bar, back piston bar is plugged in secondary piston bar, make secondary piston bar and back piston bar can mutual noninterference when action, ensure that the independence of secondary piston bar and the action of back piston bar, simultaneously, owing to adopting non-linkage structure between secondary piston bar and back piston bar, when making utility model works, sensitivity is higher.

Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
Modular cylinder as shown in Figure 1, comprise the front cylinder barrel 1 and rear cylinder barrel 2 that arrange vertically, front cylinder barrel 1 is connected by intermediate mass 3 with rear cylinder barrel 2, the front end of front cylinder barrel 1 is provided with protecgulum 4, the rear end of rear cylinder barrel 2 is provided with bonnet 5, secondary piston 6 is provided with in front cylinder barrel 1, secondary piston 6 is fixedly connected with secondary piston bar 7, the end of secondary piston bar 7 is passed protecgulum 4 and is stretched out in the outside of front cylinder barrel 1, back piston 8 is provided with in rear cylinder barrel 2, back piston 8 is fixedly connected with back piston bar 9, secondary piston bar 7 is provided with the shaft through-hole 10 with back piston bar 9 corresponding matching, the end of back piston bar 9 is successively through intermediate mass 3, secondary piston 6 and shaft through-hole 10, specifically, to coordinate with other mechanical components for the ease of back piston bar 9 and install, the end of back piston bar 9 stretches out in the outside of secondary piston bar 7.
The utility model by arranging the shaft through-hole 10 with back piston bar 9 corresponding matching in secondary piston bar 7, the end of back piston bar 9 is successively through intermediate mass 3, secondary piston 6 and shaft through-hole 10, compared with prior art, the utility model axial dimension arranges less, effectively reduce the overall volume of cylinder body, thus save installation footprint, and, owing to arranging shaft through-hole 10 in secondary piston bar 7, back piston bar 9 is plugged in secondary piston bar 7, make secondary piston bar 7 and back piston bar 9 can mutual noninterference when action, ensure that the independence of secondary piston bar 7 and back piston bar 9 action, simultaneously, owing to adopting non-linkage structure between secondary piston bar 7 and back piston bar 9, when making utility model works, sensitivity is higher.
Clutch shaft bearing 11 is provided with between back piston bar 9 and secondary piston bar 7, the second bearing 12 is provided with between protecgulum 4 and secondary piston bar 7, by arranging clutch shaft bearing 11 and the second bearing 12, effectively reduce wearing and tearing during utility model works, thus extend working life of the present utility model, specifically, clutch shaft bearing 11 and the second bearing 12 are all set to sliding bearing.
In order to avoid the impurity such as dust during work enter the utility model inside, between protecgulum 4 and secondary piston bar 7, between secondary piston bar 7 and back piston bar 9, be all embedded with dust ring 13.Secondary piston 6 is provided with the bumper 14 with intermediate mass 3 corresponding matching, and by arranging bumper 14, effectively reduce the shock between secondary piston 6 and intermediate mass 3, protected effect is better.
