DETAILED DESCRIPTION

[0016] The utility model is further described below in conjunction with the accompanying drawings:

[0017] Referring to the accompanying drawings: the finger guard structure of the sewing machine in this embodiment includes a needle plate 1, a main presser foot 2 is arranged on the needle plate 1, the main presser foot 2 is used to install a finger guard 4, a machine needle 3 is arranged on one side of the main presser foot 2, the machine needle 3 is located above the needle plate 1, and a finger guard 4 is arranged on the main presser foot 2. The finger guard 4 is used to protect the fingers of the sewing worker. The finger guard 4 is provided with a front finger guard 4-1, a middle finger guard 4-2, and a rear finger guard 4-3. The finger guard 4 includes a front finger guard 4-1, a middle finger guard 4-2, and a rear finger guard 4-3. Each part plays a corresponding role. The front finger guard 4-1 is arranged in a water drop shape. This arrangement allows the front portion of the finger guard 4-1 to be rotated for adjustment when it is needed. The front portion of the finger guard 4-1 can be rotated according to the needs of the sewing worker so that the middle portion of the finger guard 4-2 and the rear portion of the finger guard 4-3 can reach the required positions for work, thereby achieving an adjustable effect. The finger guard 4 can be adjusted in position to match the use of different sewing workers and has a wide range of applications. A presser foot screw 5 is provided on the front portion of the finger guard 4-1, and the front portion of the finger guard 4-1 is installed on the main presser foot 2 through the presser foot screw 5. The front portion of the finger guard 4-1 is installed through the presser foot screw 5, so that the finger guard 4 can be installed on the main presser foot 2, which is convenient for disassembly and maintenance.

[0018] The middle part 4-2 of the finger guard is located at the front of the needle 3, and the middle part 4-2 of the finger guard is arranged in a horizontal state. In this way, the middle part 4-2 of the finger guard can play a protective role at the front of the needle, and the sewing worker is safely protected.

[0019] The rear portion 4-3 of the finger guard is arranged in an arc shape and is located on the side of the needle 3. In this way, the rear portion 4-3 of the finger guard can protect the sewing worker at the side of the needle 3. The arc structure of the rear portion 4-3 of the finger guard can facilitate threading on the one hand, and can also play a protective role on the side of the needle 3 on the other hand, thereby increasing the protection range and improving the protection effect.

[0020] The front part 4-1 of the finger guard is connected with a positioning section 4-4, which is located at the front of the main presser foot 2.
