A suture machine body 15 is fixedly connected to the top of the support frame 2. A lifting rod 16 is provided at the bottom of the suture machine body 15. A connecting plate 17 is provided on the outer wall of the lifting rod 16, and connecting rods 19 are slidably connected to the inside of the two sides of the connecting plate 17. An insert block 21 is fixedly connected to the bottom of the connecting rod 19 on one side, and a pressing plate 20 is fixedly connected to the bottom of the connecting rod 19 on the other side. A pair of springs 18 are provided between the connecting plate 17 and the connecting rods 19 on both sides, and the insert block 21 is slidably connected in the inner cavity 6. The outer shell 5 and the inner cavity 6 are both L-shaped, and the slider 8 is slidably connected in the vertical direction of the inner cavity 6, and the cross plate 11 is slidably connected in the horizontal direction of the inner cavity 6. The cross plate 11 is rectangular, and the slider 8 is a right triangle. The inclined surface of the slider 8 corresponds to the inclined surface of the insert block 21, and the insert block 21 is slidably connected to the slider 8. A pair of limit rods 14 are fixedly connected to the top of the housing 5, and a pair of corresponding fixed blocks 4 are fixedly connected to the inner side wall of the support frame 2, and the limit rods 14 are slidably connected in the fixed blocks 4. The connecting rod 19 is composed of a crossbar and a vertical rod perpendicular to the bottom of the crossbar, and one end of the spring 18 is fixedly connected to the bottom of the crossbar of the connecting rod 19, and the other end of the spring 18 is fixedly connected to the connecting plate 17. A connecting ring 22 is detachably installed at the other end of the lifting rod 16, and a suturing head 23 is provided at the bottom of the connecting ring 22.

[0025] The edge of the quilt cover to be sewn is flattened and placed at the bottom of the fixed head 13, and then the electric push rod 3 is started, which drives the shell 5 to move downward. When the shell 5 moves downward, the direction is kept stable by the limit rod 14, and the internal slider 8 and the cross plate 11 move downward accordingly. The downward movement of the cross plate 11 causes the fixed head 13 to press the quilt cover and fix its position. Next, the lifting rod 16 at the bottom of the support frame 2 is started, which drives the connecting plate 17 to move downward, and the connecting plate 17 drives the connecting rods 19 on both sides to move downward. The downward movement of the connecting rod 19 squeezes the spring 2 18, and the insert block 21 at the bottom of the left connecting rod 19 is inserted into the inner cavity 6 of the shell 5, pushing the slider 8 to move left. When the slider 8 moves, it is kept in the slide groove 7 by the limit block 9 and squeezes the spring 10. This process causes the cross plate 11 to move left, cooperate with the fixed head 13 to tighten the quilt cover. The pressing plate 20 at the bottom of the right connecting rod 19 also presses the other edge of the quilt cover at the same time, and quickly realizes the fixed positioning of the quilt cover.

[0026] Working principle: when the staff needs to sew the quilt cover, first flatten the edge of the quilt cover to be sewed and place it at the bottom of the fixed head 13. At this time, the electric push rod 3 is started, and the outer shell 5 is driven to move downward under the action of the electric push rod 3, and the outer shell 5 is limited on the fixed block 4 by the limit rod 14 when moving downward, so that the outer shell 5 maintains the same direction when moving. At this time, the outer shell 5 will drive the internal slider 8 and the cross plate 11 to move downward when moving downward, and the cross plate 11 will drive the fixed head 13 to move downward, so as to press and fix the quilt. At this time, the lifting rod 16 at the bottom of the support frame 2 is started to drive the connecting plate 17 to move downward. When the connecting plate 17 moves downward, it will drive the connecting rods 19 on both sides to move downward at the same time, and the connecting rod 19 will squeeze the spring 2 18 when moving downward. At the same time, the plug block 21 at the bottom of the left connecting rod 19 is in the downward process. The quilt cover is inserted into the inner cavity 6 in the shell 5, and the slider 8 is slowly squeezed and pushed to move the slider 8 to the left, and the slider 8 is limited in the slide groove 7 by the limit block 9 when moving. At the same time, the slider 8 will squeeze the spring 10 when moving. At this time, the cross plate 11 will be pushed to move to the left, and the fixing head 13 will be driven to move, so as to tighten the quilt cover, and the pressure plate 20 at the bottom of the right connecting rod 19 will press the other edge of the quilt cover, thereby achieving the effect of fast fixing and positioning. After the fixation is completed, the sewing machine body 15 is started, and the sewing head 23 is cooperated to start sewing the quilt cover, and the sewing head 23 can be removed from the lifting rod 16 through the connecting ring 22. After the sewing is completed, the connecting plate 17 and the shell 5 are raised, and the spring 2 18 and the spring 10 are restored, so as to start the next step of sewing.
