[0028] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0029] Example 1

[0030] See also Figure 1-4 As shown, a button sewing machine that is easy to operate includes a body 1, a buttoning machine 2, a machine head 3 and an adjustment mechanism. The buttoning machine 2 and the machine head 3 are both mounted on the surface of the body 1 and are used for loading and sewing buttons.

[0031] The surface of the body 1 is fixedly connected with a base 5, which is used to support the buttons and the adjustment mechanism;

[0032] The adjustment mechanism includes a mounting block 4, which is mounted on a base 5. A slide 6 is slidably connected to the surface of the mounting block 4, and the slide 6 is "U" shaped;

[0033] The two short arm end surfaces of the slide plate 6 are rotatably connected to the pressure plate 8 through a hinge;

[0034] Positioning rod 16, the surface of the slide 6 is fixedly connected to the extension block 15, the surface of the extension block 15 is slidably connected to the positioning rod 16 through a spring. The end of the positioning rod 16 is fixedly connected to the surface of the pressing plate 8, and the surface of the slide 6 is placed with cloth 19;

[0035] A positioning mechanism is provided on the surface of the mounting block 4 for lateral positioning of the slide plate 6. The positioning mechanism includes a top shaft 13, which is slidably connected to the surface of the mounting block 4 through an elastic member. A positioning hole 7 is provided on the surface of the slide plate 6 relative to the top shaft 13. There are multiple positioning holes 7, which are equidistantly designed. A nail shaft 9 is fixedly connected to the surface of the pressure plate 8. The nail shaft 9 is conical, and a nail hole is provided on the surface of the short arm end of the slide plate 6 relative to the nail shaft 9.

[0036] When working, the adjusting mechanism is installed on the surface of the base 5 through the mounting block 4, and then the pressing plate 8 is lifted. At this time, the pressing plate 8 will rotate around the hinge. When the pressing plate 8 rotates, it will drive the positioning rod 16 to slide on the surface of the extension block 15, and at the same time squeeze the spring. After the pressing plate 8 is opened, the cloth 19 is placed on the surface of the slide 6, and then the pressing plate 8 is released. The cloth 19 is fixed by the pressing plate 8. When the pressing plate 8 is attached to the surface of the cloth 19, the nail shaft 9 is driven to press on the surface of the cloth 19. The nail shaft 9 is made of rubber, which can further increase the friction and prevent the cloth 19 from loosening. After the cloth 19 is fixed, the button sewing machine body 1 is turned on, and the buttoning machine 2 places the button Placed on the machine head 3, the staff can drive the cloth 19 to move under the machine head 3 by directly sliding the slide plate 6. The slide plate 6 cooperates with the mounting block 4 to assist the staff in moving the cloth 19 to sew buttons, thereby avoiding crooked sewing, thereby improving the yield rate and reducing the risk of hand injury to the staff. When the slide plate 6 slides, the positioning hole 7 will be driven to squeeze the top shaft 13. Because the surface of the top shaft 13 has an arc angle, the top shaft 13 cooperates with the positioning hole 7 to create a gap when the slide plate 6 slides. For longer cloth 19 with a fixed button spacing, it can assist the staff in positioning, thereby ensuring the accuracy of button sewing.

[0037] A through slot 11 is provided on the surface of the slide 6, and the mounting block 4 is in an "L" shape. The slide 6 is slidably connected in the short arm end of the mounting block 4. A sliding shaft 12 is fixedly connected in the through slot 11. The sliding shaft 12 passes through the mounting block 4 and is slidably connected. A spring is sleeved on the surface of the sliding shaft 12. One end of the spring is fixedly connected to the side wall of the through slot 11, and the other end of the spring is fixedly connected to the surface of the mounting block 4.

[0038] During operation, the sliding of the slider will stretch the spring on the surface of the sliding shaft 12 to generate elastic force. When the slide plate 6 moves to the extreme position, the sewing of the button is completed. At this time, the pressing plate 8 is lifted to remove the cloth 19, and the spring will drive the slide plate 6 to reset, and then prepare for the button sewing operation of the next piece of cloth 19. The "L"-shaped mounting block 4 can ensure that the docking position of the slide plate 6 and the base 5 is in a flush state, reducing wear caused by unevenness.

[0039] A pressing shaft 20 is slidably connected in the slide 6, and a pull rope 21 is fixedly connected to the surface of the pressing shaft 20. An insertion shaft 17 is slidably connected in the extension block 15 through a spring. One end of the pull rope 21 away from the pressing shaft 20 is fixedly connected to the end of the insertion shaft 17. A notch 18 is provided on the surface of the positioning rod 16 relative to the position of the insertion shaft 17. A mounting hole is provided on the surface of the base 5. A spring piece 14 is fixedly connected to the surface of the mounting block 4. The other end of the spring piece 14 is a free end, and a slot is provided in the mounting hole relative to the position of the spring piece 14.

[0040] When working, after the pressing plate 8 is lifted, the pressing plate 8 will drive the positioning rod 16 to slide on the extension block 15. After the pressing plate 8 moves to the extreme position, the insertion shaft 17 will be stuck in the slot 18, positioning the positioning rod 16, which makes it easier for the staff to place the cloth 19. After the position of the cloth 19 is determined, the cloth 19 is tightened and pressed down. At this time, the cloth 19 will squeeze the pressing shaft 20, causing the pressing shaft 20 to move downward. At the same time, the pressing shaft 20 will drive the pull rope 21 to pull the insertion shaft 17, causing the insertion shaft 17 to disengage from the slot 18, releasing the limit on the positioning rod 16. At the same time, the spring drives the positioning rod 16 to bounce up, driving the pressing plate 8 to fit the surface of the cloth 19. Through the design of the insertion rod and the slot 18, the convenience of installing the cloth 19 can be improved, and the efficiency of sewing can be indirectly improved. The mounting block 4 can be quickly installed and disassembled by cooperating with the card slot of the spring piece 14, and then the slides 6 of different specifications can be replaced.
