[0029] See also Figure 1-4A tool for sewing automobile plastic accessories, the tool comprises an inner presser foot 1 and an outer presser foot 2 which match each other and are used to press strip-shaped plastic parts. The outer presser foot 2 is provided with a slot 8, and the inner walls on both sides of the slot 8 are provided with sliding slots 9. Sliding blocks 10 are slidably installed in the two sliding slots 9. By setting the sliding slots 9, the sliding blocks 10 can be slidably installed inside, and are embedded in the installation.

[0030] Among them, the outer walls of the two sliding blocks 10 on one side close to each other are fixedly installed with limit blocks 11. By setting the limit blocks 11, the automobile plastic accessories can be limited and moved. Two threaded holes 13 are symmetrically opened on the outer pressure foot 2, and adjusting bolts 14 are screwed in the two threaded holes 13. The bottom ends of the two adjusting bolts 14 are in contact with the corresponding limit blocks 11.

[0031] When in use, by rotating the adjusting bolt 14, the adjusting bolt 14 will rotate and move upward to release the limiting fixation of the sliding block 10. At this time, the sliding block 10 and the limiting block 11 can be moved, so that the distance between the two limiting blocks 11 can be adjusted according to the width of the automotive plastic accessories, thereby facilitating the positioning and installation of automotive plastic accessories with different widths. It is more flexible in use and has higher adaptability.

[0032] For details, please refer to Figure 1-2 The outer walls of the two limit blocks 11 on one side close to each other are all inclined. The outer walls of the two limit blocks 11 on one side close to each other are all inclined, so as to facilitate the guided movement of the automobile plastic parts.

[0033] For details, please refer to Figure 1-2 An inner shovel foot 3 is fixedly mounted on one side outer wall of the inner presser foot 1, and the inner shovel foot 3 presses the plastic accessory inward.
