[0046] The fixing belt 5 is passed around the fixed column 1 and the limiting roller 6, the fixing sleeve 7 is clamped on the fixed folding rod 8, and the threaded rod 10 is rotated. Since the sliding block 9 is slidably connected with the fixed plate 3, the sliding block 9 can only move laterally. The threaded rod 10 drives the sliding block 9 to move laterally, the sliding block 9 drives the fixed folding rod 8 to move, the fixed folding rod 8 drives the fixing sleeve 7 to move, and then drives the fixing belt 5 to move, so that the fixing belt 5 is wrapped around and squeezed the fixed column 1, and the fixed plate 3 is fixed with the elastic arc plate 4. The fixing belt 5 is made of flexible material and can meet the use of fixed columns 1 of different directions.

[0047] As an embodiment of the present invention, please refer to Figure 1 and Figure 3 , the second fixing mechanism comprises:

[0048] A bidirectional threaded rod 11 is rotatably connected to the fixed plate 3;

[0062] The oblique arc block 20 is connected to the other end of the limiting rod 18 and abuts against the speaker body 2, and the side of the oblique arc block 20 away from the protective net 17 is a bevel;

[0063] The elastic member 21 has one end connected to the bevel arc block 20 and the other end connected to the fixing ring 16 .

[0064] The fixing ring 16 is pressed, and the bevel block 20 abuts against the speaker body 2. Since the side of the bevel block 20 away from the protective net 17 is a bevel, the bevel block 20 moves longitudinally and squeezes the elastic member 21. When the side of the bevel block 20 away from the fixing ring 16 abuts against the speaker body 2, the fixing ring 16 is fixed under the reaction force of the elastic member 21. The elastic member 21 can be a spring, a spring sheet, etc.

[0065] The working principle of the utility model is as follows: the fixing belt 5 is passed around the fixing column 1 and the limiting roller 6, the fixing sleeve 7 is clamped on the fixing folding rod 8, the threaded rod 10 is rotated, and since the sliding block 9 is slidably connected with the fixing plate 3, the sliding block 9 can only move laterally, the threaded rod 10 drives the sliding block 9 to move laterally, the sliding block 9 drives the fixing folding rod 8 to move, the fixing folding rod 8 drives the fixing sleeve 7 to move, and then drives the fixing belt 5 to move, so that the fixing belt 5 is wrapped around and squeezed on the fixing column 1, and the fixing plate 3 is fixed with the elastic arc plate 4, and the fixing belt 5 is a flexible material, which can meet the use of different direct fixing columns 1, and the bidirectional threaded rod 11 is rotated, and under the limit of the connecting tube 13 and the sliding rod 14, the bidirectional The threaded rod 11 drives the threaded sleeve 12 to move laterally, and the threaded sleeve 12 drives the fixed arc plate 15 to move laterally, so that the fixed arc plate 15 abuts against the outer shell of the speaker body 2 to fix the speaker body 2, press the fixing ring 16, and the beveled arc block 20 abuts against the speaker body 2. Since the side of the beveled arc block 20 away from the protective net 17 is a bevel, the beveled arc block 20 moves longitudinally to squeeze the elastic member 21. When the side of the beveled arc block 20 away from the fixing ring 16 abuts against the speaker body 2, the fixing ring 16 is fixed under the reaction force of the elastic member 21, and the protective net 17 protects the front opening of the speaker body 2 to prevent birds, animals or insects from nesting therein and affecting the use of the speaker body 2.
