The transverse moving column 10 is located inside the rectangular through groove and is slidably connected with the L-shaped mounting plate 5 through the rectangular through groove. The setting of the rectangular through groove enables the transverse moving column 10 to slide inside the L-shaped mounting plate 5.

[0030] A longitudinal connecting column 11 is fixed to the outside of the transverse moving column 10, and both sides of the longitudinal connecting column 11 are rotatably connected to longitudinal transmission columns 12 through pin shafts, and one side of the longitudinal transmission column 12 is rotatably connected to a longitudinal sliding column 13 through a pin shaft. A circular slide groove is provided inside the L-shaped mounting plate 5, and the longitudinal sliding column 13 is located inside the circular slide groove and is slidably connected to the L-shaped mounting plate 5 through the circular slide groove. Through the setting of the circular slide groove, the longitudinal sliding column 13 can slide inside the L-shaped mounting plate 5;

[0031] An L-shaped connecting block 14 is fixed to the bottom of the longitudinal sliding column 13, and an arc-shaped clamping block 7 is fixed to the bottom of the L-shaped connecting block 14;

[0032] Here, the rotation of the hand wheel 8 enables the transverse threaded rod 9 to rotate, and the rotation of the transverse threaded rod 9 enables the transverse moving column 10 to slide inside the L-shaped mounting plate 5. The sliding of the transverse moving column 10 enables the longitudinal sliding column 13 to slide inside the L-shaped mounting plate 5 through the arrangement of the longitudinal connecting column 11 and the longitudinal transmission column 12. The movement of the longitudinal sliding column 13 enables the two arc-shaped clamping blocks 7 to move toward the connecting wire 3 through the L-shaped connecting block 14, thereby enabling the arc-shaped clamping blocks 7 to clamp the connecting wire 3.

[0033] In addition, the lifting mechanism includes a transverse transmission plate 15, one end of the transverse moving column 10 close to the oblique mounting plate 2 is rotatably connected to the transverse transmission plate 15 through a pin shaft, one end of the transverse transmission plate 15 is rotatably connected to a transverse rotating plate 16 through a pin shaft, vertical connecting columns 19 are fixed on both sides of the arc-shaped block 6, and a longitudinal guide column 18 is fixed between the two vertical connecting columns 19 and inside the vertical connecting columns 19, and the longitudinal guide column 18 is located inside the transverse rotating plate 16 and is slidably connected to the transverse rotating plate 16;

The rotation of the transverse rotating plate 16 is through the setting of the transverse through groove, so that the vertical connecting column 19 can be vertically raised inside the oblique mounting plate 2, thereby enabling the arc-shaped clamping block 6 to be raised, thereby enabling the arc-shaped clamping block 6 to be raised and fix the wire to the inside of the circular interface 4, so as to facilitate the electrical connection between the connecting wire 3 and the circular interface 4;

[0038] Working principle: When the speaker of the present technical solution is used, the rotation of the hand wheel 8 enables the transverse threaded rod 9 to rotate, and the rotation of the transverse threaded rod 9 enables the transverse moving column 10 to slide inside the L-shaped mounting plate 5. The sliding of the transverse moving column 10 is arranged through the longitudinal connecting column 11 and the longitudinal transmission column 12, so that the longitudinal sliding column 13 can slide inside the L-shaped mounting plate 5.
