At the same time, the metal shaping rod 305 inside the bellows 300 will be pulled by the cotton 301, and then the metal shaping rod 305 will pull the ring 304, and the ring 304 will be in the corrugated tube. The bellows 300 moves in the ring 304, and the ring 304 slides on the corresponding metal shaping rod 305, so that the metal shaping rod 305 and the ring 304 can move with the expansion and contraction of the bellows 300. At the same time, the microphone 301 pulls the receiving signal line 303 to move, so that the receiving signal line 303 is released from the wire take-up device 302. When in use, the user can control the contraction of the spring or the buckle by pulling the line and extend the line. After pulling the line and slowly releasing it, the line can be slowly retracted, thereby realizing the expansion and contraction of the receiving signal line 303. Using the principle of the wire take-up device 302, when one end When the receiving signal line 303 is released, the wire take-up device 302 will release the other end of the receiving signal line 303, and then the wire take-up device 302 itself will move a distance in the direction of the ring 304, so that the receiving signal line 303 inside the bellows 300 can be extended, and the receiving signal line 303 can be adjusted to a suitable length.
