The shaft seats 202 on both sides are arranged in the same direction, that is, the extending directions of the shafts 2023 on the two shaft seats 202 are the same. Taking fig. 2 as an example, the rotation shafts 2023 on the two rotation shaft bases 202 extend rightward. In alternative embodiments, the shafts 2023 on both shaft bases 202 may also extend to the left.

The clamping groove 203 is a concave groove body, the groove body is provided with a stop piece 204, the stop piece 204 is an arc-shaped elastic piece, one end of the stop piece 204 is fixedly connected with (or integrally formed with) the end part of the clamping groove 203, and the other end of the stop piece 204 is suspended above the clamping groove 203 to form a state of bending upwards. Because the stopper 204 has elasticity, when the free end (suspended end) is stressed, the whole stopper 204 can move up and down around the fixed end (end connected with the clamping groove). In a preferred embodiment, both the stopper 204 and the air intake plate 200 are plastic.

In a preferred embodiment, the other end of the air inlet plate 200 is provided with locking grooves 206 on both sides near the edge.
