[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] In order to enable those skilled in the art in the technical field to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0028] First of all, it should be noted that the directions referred to by the four orientation words of up, down, front and back in the text are all based on the Figure 1 currently shown direction.

[0029] The embodiment of the present invention discloses a switching device, including a button pliers seat 1 and a button clip connecting plate 2. The button pliers seat 1 is used to drive the button clip to descend and press the sewing material when sewing buttons. The structure and working principle of the button pliers seat 1 can both refer to the prior art.

[0030] The first end of the button clip connecting plate 2 is detachably connected to the button pliers seat 1, and the second end of the button clip connecting plate 2 is used to selectively connect the flat button clip 3 and the vertical button clip 4. However, it should be noted that the flat button clip 3 and the vertical button clip 4 are respectively fixed on both sides of the button clip connecting plate 2. The flat button clip 3 is fixedly connected to the upper side surface of the second end of the button clip connecting plate 2, and the vertical button clip 4 is fixedly connected to the lower side surface of the second end of the button clip connecting plate 2. The structures of both the flat button clip 3 and the vertical button clip 4 can refer to the prior art.

[0031] For convenient clamping, each of the flat button clip 3 and the vertical button clip 4 is provided with a button clip connecting plate 2. When using a flat button sewing machine, it is only necessary to disassemble the button clip connecting plate 2 and the button pliers seat 1, and fix the button clip connecting plate 2 equipped with the flat button clip 3 on the button pliers seat 1; when using a vertical button sewing machine, it is only necessary to disassemble the button clip connecting plate 2 and the button pliers seat 1, and fix the button clip connecting plate 2 equipped with the vertical button clip 4 on the button pliers seat 1; that is to say, when replacing flat buttons and vertical buttons, it is only necessary to disassemble the button clip connecting plate 2 and the button pliers seat 1 to replace the type of button clip, without replacing the entire sewing machine, which has good versatility and is conducive to reducing production costs.

[0032] To adapt to the structures of the flat button clip 3 and the vertical button clip 4, the button clip connecting plate 2 is not a whole flat plate, but a stepped plate. The button clip connecting plate 2 is bent to form a connecting boss 21. The upper side surface of the connecting boss 21 is used to install the flat button clip 3 so that the flat button clip 3 can press the sewing material when sewing flat buttons. Or, the lower side surface of the connecting boss 21 is used to install the vertical button clip 4 so that the vertical button clip 4 can press the sewing material when sewing vertical buttons. By changing its own structure, the button clip connecting plate 2 can meet the installation requirements of both the flat button clip 3 and the vertical button clip 4, and has good versatility.

[0033] The button clip connecting plate 2 includes a connecting platform 22 detachably connected to the button pliers seat 1. As a preferred embodiment, the lengths of both the connecting platform 22 and the connecting boss 21 each account for one-half of the length of the button clip connecting plate 2, but it is not limited to this. The connecting boss 21 is arranged higher than the connecting platform 22 so that a set height difference is maintained between the connecting boss 21 and the connecting platform 22. The upper side surface of the connecting boss 21 is arranged higher than the upper side surface of the connecting platform 22 so that an upper limiting step 23 is formed on the upper side surface of the button clip connecting plate 2. When the button clip connecting plate 2 is connected to the button pliers seat 1, the upper limiting step 23 abuts against the rear end surface of the button pliers seat 1, which is convenient for quickly limiting the installation position of the button clip connecting plate 2, saving the clamping time and improving the switching efficiency.

[0034] The lower side surface of the connecting boss 21 is arranged higher than the lower side surface of the connecting platform 22 so that a lower limiting step 24 is formed on the lower side surface of the button clip connecting plate 2. When the button clip connecting plate 2 is connected to the flat button clip 3, the lower limiting step 24 abuts against the front end surface of the flat button clip 3, which is convenient for quickly limiting the installation position of the flat button clip 3, saving the clamping time and improving the clamping accuracy.

[0035] A button clip limiting step 41 is formed on the lower side surface of the vertical button clip 4. When the vertical button clip 4 is connected to the button clip connecting plate 2, the end surface of the connecting boss 21 far from the button pliers seat 1 abuts against the button clip limiting step 41, quickly limiting the installation position of the vertical button clip 4, saving the clamping time and improving the clamping accuracy.

[0036] The connecting platform 22 and the button pliers base 1 are detachably connected by a connecting bolt 5. As a preferred embodiment, the connecting platform 22 is provided with mounting holes which are threaded holes, and the button pliers base 1 is provided with threaded grooves. The connecting bolt 5 passes through the mounting holes and mates with the threaded grooves, which can not only reliably fix the button clip connecting plate 2 on the button pliers base 1, but also facilitate the disassembly and assembly of the button clip connecting plate 2. The connecting platform 22 is provided with positioning holes 221, and positioning pins 6 are arranged in the positioning holes 221. The positioning pins 6 abut against the lower side surface of the button pliers base 1 to limit the button clip connecting plate 2 and the button pliers base 1 to maintain a set distance.

[0037] An adjusting component 7 is arranged between the connecting boss 21 and the flat button clip 3 or between the connecting boss 21 and the vertical button clip 4. The adjusting component 7 is used to adjust the position of the flat button clip 3 or the vertical button clip 4 relative to the connecting boss 21, compensate for the assembly error between the two button clips and the button clip connecting plate 2, and improve the versatility of the button clip connecting plate 2.

[0038] The adjusting component 7 includes a waist-shaped hole 71 arranged on the connecting boss 21, a plurality of fixing holes 72 arranged on the flat button clip 3 or the vertical button clip 4, and a locking bolt 73 passing through the waist-shaped hole 71 and selectively connected to the fixing holes 72. By adjusting the position of the locking bolt 73 in the waist-shaped hole 71, the relative position between the button clip connecting plate 2 and the two button clips can be adjusted. The structure is relatively simple and the operation is relatively convenient. As a preferred embodiment, the fixing holes 72 are specifically threaded holes. A waist-shaped hole 71 is symmetrically arranged on each side of the connecting boss 21. Two fixing holes 72 are arranged oppositely on each side of the flat button clip 3 or the vertical button clip 4, and the two fixing holes 72 are selectively matched with the locking bolt 73.

[0039] The button pliers base 1 is fixedly provided with a button clip hook 8, and the button clip hook 8 is a V-shaped hook with the opening facing downwards; the button clip hook 8 is used to be hooked and connected with the lifting and pressing hook 9, and the lifting and pressing hook 9 is an L-shaped hook. By optimizing the structures of the button clip hook 8 and the lifting and pressing hook 9, unity is achieved to avoid interference with the flat button clip 3 or the vertical button clip 4.

[0040] The present utility model also provides a button sewing machine, including the above-mentioned switching device, which has the same beneficial effects.

[0041] It should be noted that in this specification, relational terms such as first and second are only used to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0042] In this article, specific examples are used to elaborate on the principles and implementation modes of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present utility model, several improvements and modifications can still be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
