[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example

[0024] It should be further noted that the buttonhole opening equipment and the matching garment production workbench are both existing publicly available technologies, and therefore are not shown in the accompanying drawings of this application. Meanwhile, the tensioning component 2 in this application is installed on the opening head 1 of the buttonhole opening equipment. The two move up and down together to complete the buttonhole opening, eliminating the need for a separate drive component for the tensioning component 2. This simplifies the equipment, reduces costs, facilitates later maintenance and repair, and improves ease of use. The tensioning component 2 is mainly used to pre-tension and flatten the garment on the workbench when the buttonhole opening equipment is opening buttonholes, thereby ensuring smooth completion of the buttonhole opening, improving the accuracy and quality of the buttonhole opening, and increasing production efficiency.

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown in the figure, one embodiment of the present invention proposes a buttonhole opening device for garment production, including a tensioning component 2. The tensioning component 2 includes a mounting sleeve 201 fixedly fitted on the opening head 1. A first connecting ear plate 2013 is provided on the support plate 2012 at the lower part of the mounting sleeve 201. The first connecting ear plate 2013 is rotatably connected to the upper end of the support rod 203. The lower end of the support rod 203 is rotatably connected to the lower pressing plate 204. An elastic spring plate 205 is arranged between the support rod 203 and the support plate 2012.

[0026] When using the device, place the garment that needs to have buttonholes made on the workbench at the buttonhole opening station. Lay the garment flat and ensure it is folded and stacked. Then, the buttonhole opening device drives the opening head 1 to move toward the garment on the workbench. The tensioning component 2 also moves along with it and first contacts the garment on the workbench. At the same time, as the opening head 1 moves down, the pressing plate 204 is pushed by the support rod 203 and slides on the garment. During this process, the support rod 203 will deflect appropriately on the support plate 2012 and the pressing plate 204, causing the elastic spring plate 205 to deform appropriately, thereby flattening and tensioning the garment until the opening head 1 completes the buttonhole opening and stops moving down. Finally, the buttonhole opening device drives the opening head 1 and the tensioning component 2 to reset.

[0027] like Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, a bolt seat 2011 is fixedly connected to the side wall of the mounting sleeve 201. The bolt seat 2011 and the mounting sleeve 201 are both provided with threaded holes that are mutually connected. The limiting bolt 202 is threadedly connected to the threaded hole. After the mounting sleeve 201 is put into the designated installation position on the opening head 1, the limiting bolt 202 is directly screwed in. The limiting bolt 202 is screwed from the bolt seat 2011 and abuts against the opening head 1, fixing the mounting sleeve 201 at the installation position on the opening head 1. This achieves stable installation of the entire tensioning assembly 2 and ensures that the two are used together stably. They form a synchronous movement on the opening head 1 to flatten the garment that needs to have buttonholes and tighten the opening of the garment. This ensures that the opening head 1 can perform a stable and effective buttonhole opening operation on the garment in the future.

[0028] The support plates 2012 are arranged in a ring array at the lower end of the mounting sleeve 201. The support plates 2012 are fixedly connected to the mounting sleeve 201, and the side of the support plate 2012 located outside the mounting sleeve 201 is provided with an overlapping seat 2014, which facilitates the formation of a stable mounting seat for the support rod 203 and the elastic spring plate 205 at the lower part of the mounting sleeve 201, ensuring the stable installation of the support rod 203 and the elastic spring plate 205, and ensuring stable cooperation between them.

[0029] The upper part of the pressing push plate 204 is fixedly connected to a second connecting ear plate 2041. The second connecting ear plate 2041 is rotatably connected to the lower end of the support rod 203 through a pin, which facilitates the stable installation of the pressing push plate 204 on the support rod 203 and ensures that the support rod 203 can generate appropriate deflection to avoid motion interference and ensure stable use. The lower part of the pressing push plate 204 is fixedly connected to an abutment plate 2042. The abutment plate 2042 is provided with evenly distributed balls 2043, which facilitates the rolling of the balls 2043 on the abutment plate 2042 when the abutment plate 2042 slides on the garment, which appropriately reduces the frictional resistance between the abutment plate 2042 and the garment, avoids excessive resistance from damaging the garment, and facilitates the smooth laying of the garment on the worktable and the smooth opening of buttonholes.

[0030] One end of the elastic spring plate 205 is fixedly connected to the lap joint 2014 by screws, and the other end of the elastic spring plate 205 is fixedly connected to the support rod 203 by screws. This makes it easy to stably install the elastic spring plate 205 between the support plate 2012 and the support rod 203, providing stable and effective support for the support rod 203. When the support rod 203 is subjected to force and moves on the first connecting ear plate 2013, the elastic spring plate 205 can deform along with it. After the external force is subsequently removed, it drives the support rod 203 to move and reset, thus facilitating the next use.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
