DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The following further describes in detail the specific embodiments of the present utility model with reference to the drawings.

[0020] AsFigures 1-5 As shown in Figures 1-5 , a sewing machine control device for the disabled includes a controller 1 and a mounting base 2 arranged on the workbench surface. A rotatable rotating shaft 3 is arranged in the mounting base 2. A manual control board 4 for controlling its forward and backward rotation is mounted on the rotating shaft 3. One end of the rotating shaft 3 is connected to an operating rod 6 through a transmission mechanism 5. A pivot shaft 7 is arranged between the other end of the operating rod 6 and the controller 1. A movable ejector pin 1 8 and an ejector pin 2 9 are respectively arranged on the side surface of the controller 1. The ejector pin 1 8 and the ejector pin 2 9 are respectively located on the lower end surface of the operating rod 6 and are pushed by the operating rod 6 to perform the actions of thread cutting and presser foot lifting.

[0021] Through the design of the manual control board 4 of the present utility model, during actual use, the operation of the sewing machine can be controlled by pressing the manual control board 4 by hand. Compared with the sewing machines with conventional structures in the prior art, it can meet the needs of special disabled groups. Even if the leg functions are missing, the operation of the sewing machine can be normally controlled to complete the sewing work. When the rear side of the manual control board 4 is pressed, the rotating shaft 3 rotates clockwise, drives the operating rod 6 to rotate towards the side close to the ejector pin through the transmission mechanism 5. During the rotation of the operating rod 6, it first touches the ejector pin 1 8, causing the sewing machine to perform the presser foot lifting action, and then touches the ejector pin 2 9, causing the sewing machine to perform the thread cutting action. When the front side of the manual control board 4 is pressed, the rotating shaft 3 rotates counterclockwise, drives the operating rod 6 to rotate towards the side away from the ejector pin through the transmission mechanism 5, and at the same time drives the pivot shaft 7 to rotate, causing the sewing machine to perform the sewing action to control the start and stop of the sewing machine.

[0022] Combined with Figure 3 and Figure 4 , two mounting parts 1 10 are arranged on the side surface of the controller 1. The ejector pin 1 8 is movably arranged in the two mounting parts 1 10. The upper end of the ejector pin 1 8 passes through the mounting part 1 10 and forms a abutting part 1 11. The abutting part 1 11 is located on the lower end surface of the operating rod 6. A limiting part 1 12 is formed on the outer periphery of the ejector pin 1 8. A spring 1 13 is abutted between the lower end surface of the limiting part 1 12 and the mounting part 1 10 to realize the automatic reset of the ejector pin 1 8. The ejector pin 1 8 is a control switch and is connected to the control circuit board in the controller, so as to realize the control of the presser foot lifting of the sewing machine. The connection structure and the structure of the circuit board are the prior art. Therefore, when the ejector pin 1 8 is pushed by the operating rod 6, the presser foot lifting action will be performed.

[0023] Combined with Figure 3 and Figure 4, two mounting parts II 14 are arranged on the side of the controller 1. A second ejector pin 9 is movably arranged in the two mounting parts II 14. The upper end of the second ejector pin 9 passes through the mounting part II 14 and is formed with a second abutting part 15. The second abutting part 15 is located on the lower end face of the operating rod 6. A second limiting part 16 is formed on the outer periphery of the second ejector pin 9. A second spring 17 is abutted between the lower end face of the second limiting part 16 and the mounting part II 14 to realize the automatic reset of the second ejector pin 9. The second ejector pin 9 is a control switch and is connected to the control circuit board in the controller, so as to realize the control of the thread trimming of the sewing machine. The connection structure and the structure of the circuit board are prior arts. Therefore, when the second ejector pin 9 is pushed by the operating rod 6, the thread trimming action will be executed. The height position of the second abutting part 15 is lower than the height position of the first abutting part 11, so that in the actual operation process, when the hand control board 4 is normally pressed, the operating rod 6 first touches the first ejector pin 8 to perform the presser foot lifting action, and then touches the second ejector pin 9 to perform the thread trimming action. When the hand control board 4 is quickly pressed, because the presser foot lifting has a certain delay response, the thread trimming action will be executed first, and then the presser foot lifting action will be triggered.

[0024] An adjusting part 18 for adjusting the spring tightness is screwed in the mounting part I 10. The lower end of the first spring 13 abuts against the upper end face of the adjusting part 18. By rotating the adjusting part 8, the spring tightness can be adjusted. The adjusting structure is simple and the operation is convenient.

[0025] A fixing seat 19 is installed on the outer periphery of the rotating shaft 3. The mounting seat 2 is fixedly arranged on the upper end face of the fixing seat 19. A first pressing part 20 is formed at the front end of the mounting seat 2, and a second pressing part 21 is formed at the rear end of the mounting seat 2. The side of the pressing part is slightly upturned to facilitate hand pressing.

[0026] A clamping groove 22 is formed on the operating rod 6. A clamping post 23 is arranged on the lower side of the controller 1. A tension spring 24 is connected between the clamping post 23 and the clamping groove 22 to realize the automatic reset of the operating rod 6.

[0027] The transmission mechanism 5 includes a transverse connecting rod 25 and a vertical connecting rod 26.
