[0026] It should be noted that before the pneumatic valve position transmitter is operated, the clamping frame 3 is placed on the top of the detection telescopic end of the pneumatic valve position transmitter, and then the handle 6 is turned, which then drives the threaded rod 5 to rotate, so that the threaded rod 5 pushes the shaft clamp 8 to move through the rotating bearing 7, and then the detection telescopic end can be clamped by the clamping column 9.

[0027] The transmission assembly includes: a slideway 10, a connecting plate 11, a rack frame 12, a transmission rack 13, a rotating shaft 14 and a transmission gear 15;
