[0010] Preferably, the adjustment disc is provided with a positioning groove on its periphery, and the positioning groove is adapted to the mounting block.

[0011] Preferably, a fixed shaft is fixedly connected to the center of the end of the fixed disk near the center of the adjusting disk, and an mounting sleeve is rotatably connected to the center of the end of the adjusting disk away from the fixed disk. The fixed shaft slides through the adjusting disk and the mounting sleeve, and the mounting sleeve is fixed to the fixed shaft by a fixing bolt.

[0012] In summary, the technical effects and advantages of this utility model are as follows:

[0013] 1. In this utility model, multiple needles are arranged in a circumferential array on the side of the adjustment plate. When one of the needles breaks, the adjustment plate can be rotated until another needle is in the position of the previously broken needle. The adjustment plate is then limited by a limiting structure, and it can continue to be used until all the needles on the adjustment plate break. At this point, the adjustment plate can be replaced directly, avoiding the need to immediately find a new needle to replace a broken one, thus improving the sewing efficiency of car seat covers.

[0014] 2. In this utility model, a limiting structure including a limiting rod and a tension spring is connected between the adjusting plate and the fixed plate. When the limiting rod is inserted into the limiting groove under the action of the tension spring, the adjusting plate can be limited to prevent the adjusting plate from shaking.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example: Reference Figure 1-4 The illustrated car seat cover sewing device, which facilitates needle replacement, includes a body 1 and needles 3. The needles 3 are connected to the body 1 via a mounting mechanism 2. The mounting mechanism 2 includes a fixing frame 21, a fixing plate 22, and an adjusting plate 23. One end of the fixing plate 22 is fixedly connected to the body 1 via the fixing frame 21, and the other end of the fixing plate 22 is rotatably connected to the adjusting plate 23. A limiting structure is connected between the adjusting plate 23 and the fixing plate 22. Multiple needles 3 are arranged in a circumferential array along the periphery of the adjusting plate 23. The adjusting plate 23 is detachably connected to the fixing plate 22. When one needle 3 breaks, the adjusting plate 23 can be rotated until another needle 3 is in the position of the previously broken needle 3, and the adjusting plate 23 is limited by the limiting structure. At this time, it can continue to be used until all the needles 3 on the adjusting plate 23 break. Then, the adjusting plate 23 can be directly replaced, avoiding the need to immediately find a new needle 3 to replace it after one needle breaks, thus improving the sewing efficiency of car seat covers.

[0023] A lever 233 is fixedly connected to the end face of the adjusting disc 23 away from the fixed disc 22, making it convenient to move the adjusting disc 23.

[0024] To facilitate the disassembly and assembly of the adjustment disc 23, a fixed shaft 221 is fixedly connected to the center of the end of the fixed disc 22 near the adjustment disc 23, and an mounting sleeve 231 is rotatably connected to the center of the end of the adjustment disc 23 away from the fixed disc 22. The fixed shaft 221 slides through the adjustment disc 23 and the mounting sleeve 231, and the mounting sleeve 231 is fixed to the fixed shaft 221 by a fixing bolt 232.

[0025] The limiting structure includes a limiting rod 224 and a tension spring 223. The fixed plate 22 is provided with a through hole 222 through which the limiting rod 224 slides. The tension spring 223 is located on the side of the fixed plate 22 away from the adjusting plate 23, and the tension spring 223 is fixedly connected between the limiting rod 224 and the fixed plate 22. The adjusting plate 23 has a circumferential array of multiple limiting grooves 234 that are adapted to the limiting rod 224, and the multiple limiting grooves 234 are provided one-to-one with multiple needles 3. When the limiting rod 224 is inserted into the limiting groove 234 under the action of the tension spring 223, it can limit the adjusting plate 23 and prevent the adjusting plate 23 from shaking.

[0026] To prevent multiple needles 3 from being exposed and causing injury, a protective cover 24 is provided on the outer side of the adjusting plate 23, and the protective cover 24 is fixedly connected to the fixing plate 22. The needles 3 are located inside the protective cover 24, which provides better safety protection.

[0027] To facilitate the individual replacement of needle 3, needle 3 is detachably connected to adjustment plate 23. Specifically, an installation block 31 is fixedly connected to the end of needle 3 near adjustment plate 23. The installation block 31 is fixed to adjustment plate 23 by fixing bolt 22. Positioning groove 235 is provided on the periphery of adjustment plate 23. Positioning groove 235 is adapted to installation block 31. The installation block 31 is placed in alignment with positioning groove 235 for quick installation of needle 3.

[0028] The working principle of this utility model is as follows: When one of the needles 3 breaks, the adjustment plate 23 can be rotated until the other needle 3 is in the position of the previously broken needle 3. The adjustment plate 23 is then limited by the limiting structure. At this time, it can continue to be used until all the needles 3 on the adjustment plate 23 are broken. Then, the fixing bolt 232 can be unscrewed to directly replace the adjustment plate 23. This avoids having to find a new needle 3 immediately after one needle breaks, thus improving the sewing efficiency of car seat covers. When replacing the needle 3, simply unscrew the fixing bolt 32.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
