[0029] The adjusting mechanism 3 includes a worm 31, which is rotatably connected to the inner wall of the connecting box 1, a worm wheel 32 is meshed on the outer wall of the worm 31, a connecting shaft 33 is fixedly connected to the inner ring of the worm wheel 32, a gear 34 is fixedly connected to the outer wall of the connecting shaft 33, a rack 35 is meshed on the outer ring of the gear 34, a slider 36 is fixedly connected to the left side of the rack 35, a fixing groove 37 is fixedly connected to the inner wall of the connecting box 1, a top plate 38 is fixedly connected to the top of the rack 35, and a hand wheel 39 is fixedly connected to the right end of the worm 31.

[0030] Furthermore, the bottom of the announcer 2 is fixedly connected to the top of the top plate 38, and the connecting shaft 33 is rotatably connected to the inner wall of the connection box 1, so that the top plate 38 can drive the announcer 2 to rise.

[0031] Furthermore, a moving opening is opened on the top of the connection box 1, and the rack 35 passes through the moving opening, so that the rack 35 can move through the moving opening.

[0032] Furthermore, the outer shape of the slider 36 matches the inner wall shape of the fixing groove 37 , and the slider 36 is on the inner wall of the fixing groove 37 , so as to stabilize and limit the rack 35 .

[0033] Furthermore, the left end of the worm 31 is rotatably connected to the left side of the inner wall of the connection box 1 , and the worm 31 passes through the right side of the connection box 1 and rotates, thereby providing stable support for the worm 31 .

[0034] Embodiment 2

[0035] See also Figures 1 to 5 On the basis of the first embodiment, the reinforcement mechanism 4 further comprises a fixed box 41, the fixed box 41 is fixedly connected to the inside of the hand wheel 39, a connecting plate 42 is slidably connected to the inner wall of the fixed box 41, a connecting rod 44 is fixedly connected to the left side of the connecting plate 42, a pressing plate 45 is fixedly connected to the left end of the connecting rod 44, and a long bolt 43 is rotatably connected to the right side of the connecting plate 42, so as to further improve the stability after adjustment.
