Therefore, when the suture needle 605 descends, the triangular ring 303 can be pushed open, so that the triangular ring 303 will pass from the edge of the suture needle 605, forming the required function. This does not require an overly sophisticated structure to achieve, so even if there is a certain position offset during use, it will not affect the operation of the device.

[0022] like Figure 1 and Figure 4 As shown, a protection component 6 is provided at the upper end of the base 1, and the upper end of the protection component 6 is connected to the connection box 5, the right side of the connection box 5 is connected to the power component 7, and the lower end of the power component 7 is connected to the power connection component 8.

[0023] like Figure 1 As shown, the transmission assembly 4 includes a transmission upper wheel 401, a transmission lower wheel 402, a connecting belt 403 and a transmission belt 404, and the transmission lower wheel 402 is installed below the transmission upper wheel 401, the end of the transmission lower wheel 402 is connected to the connecting belt 403, and the right end of the transmission lower wheel 402 is connected to the transmission belt 404;

[0024] The speed regulator 804 drives the transmission lower wheel 402 to rotate through the transmission belt 404, and the connecting belt 403 interconnects the three transmission lower wheels 402, so that the three transmission lower wheels 402 all rotate, and the friction force between the transmission upper wheel 401 and the transmission lower wheel 402 on the rotating ring 301 drives the rotating ring 301 to rotate.

[0025] like Figure 4 As shown, the protection assembly 6 includes a protection box 601, a lifting plate 602 and a spring 603, and the lifting plate 602 is installed inside the protection box 601, and the springs 603 are connected to the left and right sides of the upper end of the lifting plate 602. The protection assembly 6 also includes a curved rod 604 and a suture needle 605, and the curved rod 604 is connected to the middle part of the upper end of the lifting plate 602, and the suture needle 605 is connected to the lower end of the lifting plate 602;

[0026] The suture needle 605 is wrapped by the protective box 601, so that when the suture needle 605 penetrates the belt, the protective box 601 can protect the side of the suture needle 605, avoiding the suture needle 605 from being broken by excessive force during penetration, thereby facilitating the continuous operation of the device.

[0027] like Figure 1 As shown, the power assembly 7 includes a power box 701, a motor 702, a rotating shaft 703, a rotating disk 704 and a first gear 705, and the motor 702 is installed at the right end of the power box 701, the rotating end of the motor 702 is connected to the rotating shaft 703, and the left end of the rotating shaft 703 is connected to the rotating disk 704, and the outside of the rotating shaft 703 is connected to the first gear 705.

[0028] like Figure 1 The power connection assembly 8 includes a second gear 801, a telescopic rod 802, a bearing 803 and a speed regulator 804, and the lower end of the second gear 801 is connected to the telescopic rod 802, the outside of the telescopic rod 802 is connected to the bearing 803, and the lower end of the telescopic rod 802 is connected to the speed regulator 804;

[0029] The second gear 801 drives the telescopic rod 802 which forms a rotating structure with the power box 701 through the bearing 803 to rotate.

[0030] Working principle: When using the belt sewing device, first place a spool of thread on the table of the base 1, and pass the thread end through the hole on the suture needle 605, then put the spool of thread into the spool wheel 2, and pass the thread from the outer wall of the spool wheel 2 to the base 1, and then place the belt on the base 1. Then, through the telescopic structure of the telescopic rod 802, the connection box 5 can be lowered downward, so that the protection box 601 presses the belt, and then turn on the motor 702, and drive the rotating disk 704 to rotate through the rotating shaft 703. The rotation of the rotating disk 704 can drive the curved rod 604 to rise and fall, so that the suture needle 605 can penetrate downward, so that the suture needle 605 penetrates the belt with the thread. At the same time, the first gear 705 will drive the second gear 801 to rotate, so that the second gear 801 drives the bearing 80 3 and the power box 701 constitute a rotating structure of the telescopic rod 802 rotates, the speed is adjusted by the speed regulator 804, and then the transmission lower wheel 402 is driven to rotate by the transmission belt 404, the connecting belt 403 interconnects the three transmission lower wheels 402, so that the three transmission lower wheels 402 all rotate, and the friction between the transmission upper wheel 401 and the transmission lower wheel 402 on the rotating ring 301 drives the rotating ring 301 to rotate. The speed regulation of the speed regulator 804 has the effect of making the suture needle 605 and the triangular ring 303 form a synchronization effect, so that when the suture needle 605 is inserted, the triangular ring 303 will pass through the suture needle 605, hook the thread on the suture needle 605, and then make the thread rotate around the threading assembly 3, so that the thread on the thread wheel 2 is entangled with the thread on the suture needle 605, thereby achieving the suture effect of the belt.
