[0025] Reference Figure 1 And Figure 3 As shown in the figure, hollow groove 33 is symmetrically provided on one side of fan-shaped mounting plate 31, the shape of hollow groove 33 is matched with the end part of earphone main body 4, and is used for accommodating the two ends of earphone main body; the end part of earphone main body 4 is respectively placed in the inside of hollow groove 33, and the setting of hollow groove 33 can improve the stability of earphone main body during installation, and facilitates the taking and placing operation of earphone main body.
[0026] Reference Figure 3 and Figure 4 As shown in the figure, the rear side of the surface of the rotating shaft 2 is symmetrically provided with a positioning hole 22, and the two positioning holes 22 are distributed along the circumference of the rotating shaft 2. The positioning hole 22 is consistent with the direction of the hollow groove 33, and the positioning hole 22 corresponds to the mounting position of the end of the earphone body 4. After rotating 180 degrees, the two positioning holes 22 are sequentially upward, and the two ends of the earphone are also sequentially upward. The positioning hole 22 is used for cooperating with the extrusion ball head 7, realizing the positioning of the fan-shaped mounting plate 31 at different angles, and ensuring the stability of the earphone body installation.
[0027] Reference Figure 4 As shown in the figure, the upper surface of the fixed seat 1 is provided with a boss 11, the surface of the boss 11 is integrally formed with the fixed seat 1, and the mounting hole 12 penetrating through the fixed seat 1 is vertically provided.

[0031] After the installation of one end of the earphone body 4, the fan-shaped mounting plate 31 can be turned by force to flip 180 degrees, so as to facilitate the installation of the other end. During the rotation, the rotating shaft 2 and the inner wall of the fixed seat 1 will extrude the extrusion ball head 7 through mutual shearing force, so that the extrusion ball head 7 is retracted upward. After being flipped 180 degrees, it falls into the other positioning hole 22 again to realize fixation. The rotating adjusting knob 5 can extrude the spring 6 to adjust the matching degree of the extrusion ball head 7 and the positioning hole 22.
