[0075] In this embodiment, refer to Fig.11 The hand knob is connected to the rotating rod of the reversing knob 230. By rotating the hand knob, the rotation of the reversing knob 230 can be controlled to switch the output to an automatic signal or a manual signal.

[0076] According to the above embodiment, according to the description, the overall use process is as follows: Initial setting: First, the sealing sleeve 120 is installed inside the time integration block 110 through the first fixing part 122, so that its position is relatively fixed. At this time, the regulating air inlet 123 opened on the sealing sleeve 120 is connected with the air inlet on the time integration block 110. Gas delivery: By adjusting the opening of the air outlet 121 at the bottom side wall position of the sealing sleeve 120, close to the regulating air inlet 123, the gas can enter the regulating air outlet 121, and communicate with the air inlet of the time integration block 110 to deliver the gas to the inside of the sealing sleeve 120. Manual automatic reversing module use: The manual automatic reversing module is set on the gas capacity gas circuit block 10 to control whether the gas circuit passes through the integration time module. The manual automatic reversing module includes a reversing gas circuit block 210, a reversing shunt plate 220, a reversing knob 230, a reversing knob 230 pressing plate 240 and a hand plate knob. By manually turning the hand knob, the angle of the reversing knob 230 can be changed, thereby changing the gas path and selecting whether the compressed air passes through the integral time module. Use of the reversing gas path block 210: The reversing gas path block 210 has a groove and is in a "convex" shape, which is used to install and place the reversing gas path block 210. In the overall "convex" structure of the reversing gas path block 210, the reversing branch plate 220, the reversing knob 230, the reversing knob 230 pressing plate 240 and the hand knob are placed on the gas-capacity gas path block 10. Gas path switching: By turning the reversing knob 230, the gas path can be changed, so that the first reversing air inlet 222 is connected to the reversing air inlet 223, or the second reversing air inlet 224 is connected to the annular air inlet, so that the gas can enter the interior of the gas-capacity gas path block 10. Operation of the reversing knob 230: By turning the hand knob, the reversing knob 230 is controlled to rotate, thereby controlling the reversing of the gas path to achieve the purpose of switching the gas path. The manual automatic reversing module and the reversing gas path block 210 can be operated as needed to achieve gas path switching, and at the same time control the gas delivery to the inside of the sealing sleeve 120 to switch the output to an automatic signal or a manual signal.

[0077] In this embodiment, the air capacity cavity of the air capacity air circuit block 10 is a plurality of air circuits, including: the air outlet 111 of the integral time block is connected to the air inlet of the reversing air circuit block 210 , and the air outlet 111 of the reversing air circuit block 210 is connected to the bellows connection port of the air capacity air circuit block 10 .
