Description of drawings:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is automatically controlled, a gas control schematic diagram of the present utility model.

Embodiment:Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated:

Embodiment: a kind of micro automatic reciprocating air cylinder (referring to Fig. 1, Fig. 2), it has cylinder body 1, be provided with piston 2 in the cylinder body 1, piston 2 connects piston rod 3, the front end of cylinder body 1 connects protecgulum 5, and cylinder body 1 adds special-purpose fastening glue sealing, locking with the screw thread junction of protecgulum 5 and the screw thread junction of piston 2 and piston rod 3.Piston rod 3 is the internal and external casing welded structure, and its penetralia is provided with air flue 4, is provided with second annular chamber 16 between the internal and external layer, and piston rod 3 outsides are provided with first pore 15 and second pore, 20, the first pores 15 and second pore 20 and all are communicated with second annular chamber 16.Piston rod 3 passes protecgulum 5 and connects first joint 6, first joint 6 connects second joint 9 by first flexible pipe 7, second flexible pipe 8, second flexible pipe 8 places first flexible pipe, 7 inside, form first annular chamber 14 between the two, first joint 6 is provided with gas circuit 21, the second joints 9 and is provided with first gas port 10 and second gas port 11.First gas port 10 is communicated with air flue 4, and second gas port 11 is communicated with second annular chamber 16 by first annular chamber 14, gas circuit 21, first pore 15.First gas port 10 and control box 17 outside set gas ports 12 are connected, and the set gas port 13 in second gas port 11 and control box 17 outsides is connected, and control box 17 is provided with rotary switch 18 and air inlet switch 19.Automatically controlled in the control box 17, gas control principle is referring to Fig. 2, air inlet switch 19 is handled three linked piece 22, single automatically controlled two position-5 way valves, 23 connection gas ports 12, gas port 13 by source of the gas, single automatically controlled two position-5 way valves, 23 connect hours relay ST1 and time relay ST2, rotary switch 18, single automatically controlled two position-5 way valves 23, time relay ST1 link to each other with time relay ST2 and all are connected power supply.
