[0027] The slide groove 21 is provided on the top surface of the machine body 1, and the side surface of the machine body 1 is fixedly connected with a control box 22, and a rotating rod 23 is passed through the top surface of the control box 22, and the rotating rod 23 is rotatably connected with the control box 22, and a rotating ring 24 is fixedly connected to the top surface of the rotating rod 23, and a handle 25 is passed through and rotatably connected to the top surface of the rotating ring 24, and the surface of the gear 1 26 is passed through and fixedly connected by the rotating rod 23, and the anti-slip plate 217 is released, and the stretched spring 1 218 will drive the anti-slip plate 217 to press against the shoulder strap of the backpack, and then the handle 25 is grasped and turned to drive the rotating ring 24 to rotate, and the rotating ring 24 will rotate during the rotation. The rod 23 drives the gear 1 26 to rotate together, and the inner wall of the body 1 is rotatably connected with a rotating column 219, and the rotating column 219 penetrates and is fixedly connected with the gear 2 27, and the gear 2 27 is meshed with the gear 1 26. The surface of the gear 2 27 is provided with an arc groove 28, and the slide rod 29 penetrates the arc groove 28. The rotation of the gear 1 26 will drive the meshing gear 27 to rotate together, causing the arc groove 28 provided on the surface of the gear 2 27 to contact the slide rod 29, and the top surface of the slide rod 29 is fixedly connected with the slider 210, and the top surface of the slider 210 is fixedly connected with the connecting rod 213, and the top surface of the connecting rod 213 is fixedly connected with the tensioning block 214. A circular groove 215 is formed on the top surface of the tightening block 214, and a plug rod 216 is slidably connected to the inner side of the circular groove 215, and an anti-dropping card plate 217 is fixedly connected to the top surface of the plug rod 216. Before quilting the backpack, the anti-dropping card plate 217 is first pulled up, and the anti-dropping card plate 217 will drive the plug rod 216 to rise and stretch the spring 1 218, and then the backpack strap is placed under the anti-dropping card plate 217. A spring 1 218 is fixedly connected to the bottom surface of the anti-dropping card plate 217, and the bottom end of the spring 1 218 is fixedly connected to the inner side of the circular groove 215. The inner side of the slideway 21 is fixedly connected with a guide rod 211, and the rotation of the gear 1 26 drives the gear 2 27 meshing therewith to rotate together, so that the arc groove 28 provided on the surface of the gear 2 27 contacts the slide bar 29, and forces the slide bar 29 to slide along the arc groove 28. However, the top surface of the slide bar 29 is fixed with a slider 210, and the slider 210 is penetrated by the guide rod 211, so the slider 210 is limited by the guide rod 211, and the guide rod 211 penetrates the slider 210 and is slidably connected. The side of the slider 210 is fixedly connected with a spring 212, and one end of the spring 212 away from the slider 210 is fixedly connected to the inner side of the slideway 21. The number of the screw sleeve 5 is two groups, and the two groups of screw sleeves 5 are symmetrically arranged with the center line of the cross column 6 as the symmetry axis. There are four groups of slide grooves 21, and the four groups of slide grooves 21 are arranged in a circular array with the center line of the body 1 as the axis. When the slide rod 29 slides along the arc groove 28, the slider 210 slides along the slide groove 21 and the guide rod 211, and the spring 212 is compressed. During the sliding process of the slider 210, the tensioning block 214 is driven by the connecting rod 213 to tighten the four corners of the backpack's straps.

[0028] Based on the above embodiment, before quilting the backpack, first pull up the anti-slip plate 217, the anti-slip plate 217 will drive the insertion rod 216 to rise and stretch the spring 1 218, and then place the backpack's straps under the anti-slip plate 217, then release the anti-slip plate 217, the stretched spring 1 218 will drive the anti-slip plate 217 to press against the backpack's straps, and then grab the handle 25 and turn it to drive the rotating ring 24 to rotate. During the rotation process, the rotating ring 24 will drive the gear 1 26 to rotate together through the rotating rod 23, and the rotation of the gear 1 26 will drive the gear 2 27 meshing with it to rotate together, causing the arc groove 28 on the surface of the gear 27 to contact the slide bar 29 and force the slide bar 29 to rotate. It slides along the arc groove 28, but a slider 210 is fixed to the top surface of the slide bar 29 and the slider 210 is penetrated by the guide rod 211, so the slider 210 is limited by the guide rod 211, and then when the slide bar 29 slides along the arc groove 28, the slider 210 slides along the slide groove 21 and the guide rod 211, and the spring 212 is compressed. During the sliding of the slider 210, the tensioning block 214 is driven by the connecting rod 213 to tighten the four corners of the shoulder strap of the backpack, so that the main body of the backpack is tightened, which makes it easier for the quilting needle 7 to quilt the main body of the backpack. The motor 3 is started, and the output shaft of the motor 3 can drive the screw 4 to rotate, so that the position of the quilting needle 7 is adjusted by the screw sleeve 5 and the cross column 6 for quilting.

[0029] By using four sets of tightening blocks 214 arranged in a circular array, backpacks of different shapes, such as round and square, can be tightened and then the backpack body can be quilted. At the same time, backpacks of different sizes can also be firmly fixed. The tightening degree can be adjusted by simply grasping the handle 25 and turning it, which is simple and quick to operate.

[0030] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
