Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] See also Figure 1-4The utility model provides a technical solution: it includes a processing frame 1, an upper end groove 11 is opened at the upper end of the processing frame 1, and it has a rectangular structure. A telescopic cylinder 2 is fixed at the center position inside the processing frame 1, and an end plate 21 is fixed on the upper end of the telescopic cylinder 2. A center column 5 is fixed on the upper end of the end plate 21. A circular frame 3 is installed around the center column 5. A combination component is provided at the bottom of the circular frame 3 and both ends of the end plate 21. The upper ends of the center column 5 and the circular frame 3 extend out of the upper end groove 11. A fixing frame 4 is fixed on the upper end of the processing frame 1 and around the upper end groove 11. A cylinder 41 is fixed on the fixing frame 4, and a push plate 42 is fixed to the output end of the cylinder 41.

[0019] The circular frame 3 is a multi-layer structure, and each layer of the circular frames 3 is slidably connected to each other. The inner wall of the innermost circular frame 3 is connected to the outer wall of the center column 5. A support sleeve 12 is fixed inside the processing frame 1 and located outside the telescopic cylinder 2. The support sleeve 12 is aligned with the circular frame 3. The distance between the upper end of the support sleeve 12 and the upper end of the processing frame 1 is equal to the height of the circular frame 3. When resetting, the bottom of the circular frame 3 is against the upper end of the support sleeve 12, and the position of the insertion slot 31 can be determined.

[0020] The combined component includes a telescopic plate 22 and an insertion slot 31. The telescopic plate 22 is installed on both sides of the end plate 21. Telescopic slots are opened on both sides of the end plate 21 and at positions corresponding to the telescopic plate 22. The telescopic plate 22 is slidably connected in the telescopic slot close to one end. A driving slot 23 is opened at the bottom of the telescopic plate 22. A servo motor 24 is fixed at the bottom of the end plate 21 and at a position corresponding to the driving slot 23. The output end of the servo motor 24 is located in the driving slot 23 and is fixed with a driving gear 25. The inner side wall of the driving slot 23 is fixed with a gear plate 26 that meshes with the driving gear 25.

[0021] Working principle: First, connect the entire device to an external power source, then form a circular structure with the speaker shell panels coated with glue at the corners, and then use the telescopic cylinder 2 to drive the center column 5 to rise, and use the extension of the telescopic plate 22 to insert it into the insertion slot 31, which can push the circular frame 3 to rise synchronously, so that the maximum outer diameter of the extended circular frame 3 is the same as the inner diameter of the assembled circular speaker panel, and then insert it into the periphery of the circular frame 3 to ensure that when squeezing inward, the center column 5 and the circular frame 3 are used for internal support, thereby ensuring the stability of the squeezing and avoiding deformation or even damage of the panel. Finally, use The output of the cylinder 41 pushes the push plate 42 to slide inward and squeeze the periphery of the plate. When pushing out the circular frame 3, the output end of the servo motor 24 can be used to drive the driving gear 25 to rotate, and then the gear plate 26 is used to drive the telescopic plate 22 to telescope in the telescopic slot. After the telescopic plate 22 can extend the specified length of the telescopic slot, it can be inserted into the insertion slot 31 of the specified circular frame 3. The longer the extended length, the larger the outer diameter of the circular frame 3 can be ejected. Therefore, the ejection selection of the circular frame 3 can be made according to the inner diameter of the speaker shell, thereby increasing the practicality of the entire device.
