The end of the telescopic spring 55 away from the movable plate 52 is fixedly connected to the inner wall of the right side of the adjusting frame 42.

[0026] Working principle: By pulling the polygonal plate 45 to separate it from the slot, the polygonal plate 45 is rotated to rotate the slide 44. The rotation of the slide 44 causes the movable column 41 to rotate, which in turn drives the adjustment frame 42 to rotate. The rotation of the adjustment frame 42 drives the support plate 48 to rotate, and the rotation of the support plate 48 causes the speaker microphone head 49 to be adjusted at an angle. This allows for convenient adjustment of the speaker's posture and speaking angle for different users, eliminating the need for users to hold the handheld connector 3 for communication. At the same time, by pulling the movable plate 52, the insertion rod 53 is moved and separated from the docking hole 54. Then, by pulling the support plate 48, the speaker microphone head 49 is extended and brought closer to the user's speaking area, reducing the absorption of ambient noise by the speaker microphone head 49 and preventing noise from affecting the sound quality of the listener's speech.
