[0025] like Figure 1-4 As shown, a technical solution provided by the utility model:

[0026] An adjustable presser foot for a sewing machine comprises a presser foot body 1, a fixing block 2 is arranged at the top of one side of the presser foot body 1, a mounting mechanism 3 is arranged between the presser foot body 1 and the fixing block 2, and the mounting mechanism 3 comprises a rod groove 301, a mounting groove 302 and a screw 303; a rod groove 301 is arranged at the middle part of the right side of the fixing block 2, a mounting groove 302 is arranged at the top of one side of the presser foot body 1 close to the rod groove 301, and a screw 303 passes through the rod groove 301 in the middle part of the fixing block 2 and is threadedly connected with the mounting groove 302 at the top of the presser foot body 1;

[0027] In this embodiment, when in use, the connecting piece 12 is installed at a specified position on the sewing machine. According to the different heights of the installation position, the height of the pressing foot body 1 can be adjusted to adapt. When adjusting, the adjusting knob 7 is twisted, and the adjusting knob 7 drives the threaded rod 503 on the inner side of the guide sleeve 6 to rotate. When the threaded rod 503 rotates, it drives the movable block 501 to move up and down inside the guide sleeve 6 to control the height of the pressing foot body 1, thereby achieving the purpose of easy adjustment.

[0028] like Figure 1 and Figure 2 As shown, a movable frame 4 is movably installed on the outside of the fixed block 2, and an adjustment mechanism 5 is arranged on the top of the movable frame 4. The adjustment mechanism 5 includes a movable block 501, a threaded groove 502 and a threaded rod 503. A guide sleeve 6 is arranged on the outside of the movable block 501; the top of the movable frame 4 is fixedly connected to the movable block 501, a threaded groove 502 is provided in the middle of the movable block 501, a threaded rod 503 is movably installed in the middle of the guide sleeve 6, the threaded rod 503 is threadedly connected with the threaded groove 502, and the top of the threaded rod 503 passes through the guide sleeve 6 and is fixedly connected with an adjustment button 7; a connector 12 is integrally formed on the outer wall of one side of the guide sleeve 6;

[0029] In this embodiment, when the pressing foot body 1 needs to be replaced, the pressing foot body 1 is raised to the highest point, and then the right side of the pressing foot body 1 is flipped downward, and then the screws 303 between the fixing block 2 and the pressing foot body 1 are removed using a tool, so that the pressing foot body 1 can be quickly removed from the bottom end of the fixing block 2, thereby achieving the purpose of facilitating quick replacement.

When in use, the right side of the pressing foot body 1 can be lifted. After the right side of the pressing foot body 1 is lifted, the spring 11 is stretched. When the pressing foot body 1 is released, the spring 11 will control the left side of the pressing foot body 1 to reset and lift up.

[0034] Working principle: When in use, install the connecting piece 12 at the specified position on the sewing machine. According to the height of the installation position, it can be adapted by adjusting the height of the pressing foot body 1. When adjusting, twist the adjusting knob 7, and the adjusting knob 7 drives the threaded rod 503 on the inner side of the guide sleeve 6 to rotate. When the threaded rod 503 rotates, it drives the movable block 501 to move up and down inside the guide sleeve 6 to control the height of the pressing foot body 1. When the pressing foot body 1 needs to be replaced, raise the height of the pressing foot body 1 to the highest point, then flip the right side of the pressing foot body 1 downward, and then use a tool to remove the screw 303 between the fixed block 2 and the pressing foot body 1, so that the pressing foot body 1 can be quickly removed from the bottom end of the fixed block 2.
