[0019] The U-shaped connecting frame 2 is arranged between the pneumatic mechanism 1 and the valve 5 of the drain valve. In order to further prevent the connecting frame 2 from rusting, a layer of anti-rust paint is applied on the connecting frame 2 or a zinc layer is electroplated by electroplating. A first through hole 201 is provided in the middle of the upper side plate of the connecting frame 2 close to the pneumatic mechanism 1, and the first through hole 201 is connected to the execution hole provided on the pneumatic mechanism 1. Four internal threaded holes are provided on the upper side plate of the connecting frame 2 around the first through hole 201, and the four internal threaded holes are respectively threadedly mounted with components for fixing the upper side plate of the connecting frame 2 to the pneumatic mechanism 1. The upper end of the connecting shaft 4 passes through the first through hole 201 and is clamped in the execution hole, so that the connecting shaft 4 can rotate synchronously with the rotation of the execution hole.

[0020] like Figure 2 As shown, the two sides of the lower side plate on the connection frame 2 that is located opposite to the first through hole 201 extend toward the corresponding outer sides to form an extension plate 203, which is distributed along the length direction of the lower side plate of the connection frame 2, and the extension plate 203 and the connection frame 2 are integrally formed. Two internal threaded holes are provided on each extension plate 203, and the two internal threaded holes are evenly spaced along the length direction of the extension plate 203.

And a positioning nut is fitted at the bottom of each threaded end of each U-shaped threaded steel bolt 6. The two ends of each U-shaped threaded steel bolt 6 respectively pass through the opposite internal threaded holes on the two extension plates 203 and are fitted with lock nuts, so that the lower side plate of the connection frame 2 and the valve 5 are fixedly connected.
