In use, for a single air switch, the clamping arms 102c are firstly pulled out from the mounting seat 101a, so that the clamping plates 101c at the two ends of the clamping arms 102c are clamped at the two sides of the air switch, and under the action of the second springs 102a inside the mounting seat 101a, the clamping plates 101c can tightly clamp the two ends of the air switch, thereby fixing the device on the air switch. Then, another matched card board 101c is installed in the slide rail 101b on the top of the mounting seat 101a, the distance between the two card boards 101c is adjusted, and then the identification card 101d with the written identification is inserted into the card slot 101c-1 between the two card boards 101c. As the end part of the clamping plate 101c is provided with the telescopic block 101c-4, under the action of the first spring 101c-3, the telescopic block 101c-4 can be tightly propped in the slide rail 101b, so that the clamping plate 101c can not move randomly.

For a plurality of air switches in a row, a plurality of devices are required to be connected in series. During the process, when the engagement plates 201a are inserted into each other, the telescopic columns 201b at the ends of the engagement arms 102c are squeezed to be retracted into the engagement arms 102c, when the telescopic columns 201b move inward, the first connecting rods 201c connected with the telescopic columns 201b rotate, and when the first connecting rods 201c rotate, the second connecting rods 201d are driven to move horizontally, the shift rods 201d-1 at the ends of the second connecting rods 201d move through the wedge-shaped blocks 201e-1 and shift the locking columns 201e to exit the locking holes 101c-2 on the clamping plates 101c, and at the moment, the clamping plates 101c are unlocked and can be extracted to be used as a device for fixing the signboard 101d and placed in the slide rails 101b on the installation seats 101a.

Since the sizes of the air switches are different, the air switches do not correspond to the air switches below in order to prevent the plurality of mounting seats 101a from being shifted in position after being connected in series. When the clamping device is connected, the pressing plate 202b-2 can be pushed, the adjusting rod 202b moves inwards at the moment, the clamping block 102d is separated from the connecting plate 102b and the clamping arm 102c, so that the clamping arm 102c is separated from the second spring 102a and can freely stretch and retract, the installation seat 101a is ensured to be positioned right above the air switch, and the clamping arm 102c can be ensured to stop at any place due to the fact that the end toothed plate 202b-1 of the adjusting rod 202b is matched with the rack 202d on the outer side of the installation seat 101a. The device can be used on a single air switch and also can be used on a plurality of air switches in a row, so that the detached parts can also be directly used for fixing the signboard.

It should be noted that the above-mentioned embodiments are only for illustrating the technical solutions of the present invention and not for limiting, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, which should be covered by the claims of the present invention.
