[0029] See attached Figure 1-3In this embodiment, the output end of the motor 5 is fixedly connected to a fixing rod 6, and a circular plate 7 is fixedly sleeved on the fixing rod 6. The fixing assembly 8 is connected to the circular plate 7, so as to facilitate automatic switching of the fixing assembly 8; the fixing assembly 8 includes a moving plate 81, a connecting block 82, a sewing needle 83, a threaded rod 84, a slider 85, a strong magnet 86 and a strong magnet 2 87. A sliding groove 1 is provided on the circular plate 7, and the moving plate 81 slides in the sliding groove 1. The top of the moving plate 81 is fixedly connected to a connecting block 82, and the connecting block 82 is connected to the connecting rod 4, so as to facilitate the driving shaft 3 to drive the moving plate 81 to move up and down through the connecting rod 4 and the connecting block 82; a slot is provided at the bottom of the moving plate 81, and a sewing needle 83 is inserted into the slot. Sewing needle 83, one end of the movable plate 81 is threadedly connected with a threaded rod 84, and the threaded rod 84 is plugged into the sewing needle 83 to facilitate the fixation of the sewing needle 83; through the drive of the motor 5, the output end of the motor 5 drives the fixed rod 6 to rotate on the workbench 1, and at the same time, the fixed rod 6 drives the fixed component 8 to rotate through the circular plate 7. During this process, the circular plate 7 drives the connecting block 82 to rotate through the movable plate 81, and makes the connecting rod 4 disengage from the T-slot 11 on the connecting block 82, and makes the connecting block 82 on the other movable plate 81 connected to the connecting rod 4, and at the same time stops the drive of the motor 5, so that the effect of automatic replacement of the sewing needle 83 can be achieved without stopping the machine.

[0030] See attached Figure 3 In this embodiment, a groove 1 is provided on the top of the movable plate 81, and a strong magnet 1 86 is fixedly installed in the groove 1. A strong magnet 2 87 is adsorbed and connected to the strong magnet 1 86. The strong magnet 2 87 is fixedly connected to the circular plate 7, which is convenient for limiting and fixing the movable plate 81, and then convenient for connecting the connecting block 82 with the connecting rod 4; two sliders 85 are fixedly connected to the movable plate 81, and the two sliders 85 are both slidably connected to the circular plate 7. The circular plate 7 is provided with a plurality of sliding grooves 2 12, and the two sliders 85 slide in the corresponding sliding grooves 2 12 respectively, so as to achieve the effect of smooth sliding of the movable plate 81; a T-slot 11 is provided on the connecting block 82, and the connecting rod 4 slides in the T-slot 11, which is convenient for connecting the connecting block 82 with the connecting rod 4, and the driving shaft 3 drives the connecting block 82 to move; a slot is provided on the sewing needle 83, and the slot corresponds to the threaded rod 84, so as to facilitate clamping and fixing the sewing needle 83.

[0031] Working principle: When in use, firstly, the fabric 9 and the PE foam tape 10 are aligned with the sewing needle 83, and then, the driving shaft 3 on the electric sewing machine body 2 is driven to make the connecting rod 4 move up and down, and at the same time, the connecting rod 4 drives the moving plate 81 to slide synchronously in the sliding groove 1 on the circular plate 7 through the connecting block 82, and at the same time, the moving plate 81 drives the sewing needle 83 to move synchronously through the transmission of the threaded rod 84, so as to achieve the effect of automatically sewing the fabric 9 and the PE foam tape 10;

[0032] When the sewing needle 83 needs to be replaced, the driving shaft 3 is firstly driven to connect the strong magnet 1 86 on the movable plate 81 with the strong magnet 2 87. Then, the motor 5 is driven so that the output end of the motor 5 drives the fixed rod 1 6 to rotate on the workbench 1. At the same time, the fixed rod 1 6 drives the fixed assembly 8 to rotate through the circular plate 7. During this process, the circular plate 7 drives the connecting block 82 to rotate through the movable plate 81, and causes the connecting rod 4 to disengage from the T-slot 11 on the connecting block 82, and causes the connecting block 82 on another movable plate 81 to connect with the connecting rod 4. At the same time, the driving of the motor 5 is stopped, so that the sewing needle 83 can be automatically replaced without stopping the machine.

[0033] Afterwards, the staff rotates the threaded rod 84 to release the fixation of the damaged sewing needle 83 by the clamp 13, and then pulls the sewing needle 83 out of the corresponding slot on the movable plate 81, thereby achieving the removal of the sewing needle 83. Conversely, the sewing needle 83 can be installed.

[0034] The technical progress achieved by the utility model compared with the prior art is that the sewing needle can be automatically replaced without stopping the machine through the cooperation of various components, and the normal sewing operation is not delayed during replacement, which greatly improves the work efficiency. At the same time, the sewing needle is easy to disassemble and assemble, which further improves the work efficiency and is more practical.
