[0050] In this embodiment, the bevel gear set 9 consists of a first bevel gear and a second bevel gear, and the edge of the first bevel gear is meshed with the second bevel gear; the turntable 10 is fixedly connected to the axis of the first bevel gear, and is used to drive the first bevel gear to rotate. The turntable 10 consists of two cylinders with different diameters, and the cylinder with a smaller diameter is located at the edge of the cylinder with a larger diameter; the second eccentric gear 8 is coaxially arranged with the second bevel gear and rotates with the second bevel gear; the first eccentric gear 7 is arranged on the side of the second eccentric gear 8 away from the turntable 10, and is meshed with the second eccentric gear 8. When the second eccentric gear 8 rotates, at the same time The first eccentric gear 7 is driven to rotate and at the same time, the first eccentric gear 7 is pushed to move horizontally; the center of the moving member 6 is rotatably connected to the axis of the first eccentric gear 7, and the first eccentric gear 7 rotates under the support of the moving member 6 and pushes the moving member 6 to move horizontally; the moving plate 5 is arranged on the side of the moving member 6 away from the second eccentric gear 8, and is fixedly connected to the moving member 6, and moves horizontally with the moving member 6; the first spring is sleeved on the surface of the moving plate 5 and is located between the moving member 6 and the workbench 1. When the moving member 6 moves in the direction away from the second eccentric gear 8, the first spring will be compressed, and the moving member 6 will move horizontally. Figure 5 The first spring shown is in a compressed state; the first connecting member 4 is composed of a first vertical plate and two groups of second horizontal plates, the two ends of the first vertical plate are fixedly connected to one end of the two groups of second horizontal plates, the end of the lower second horizontal plate away from the first vertical plate is fixedly connected to the movable plate 5, and the end of the upper second horizontal plate away from the first vertical plate is fixedly connected to the positioning plate 3, and the first connecting member 4 drives the positioning plate 3 to move horizontally.

[0051] When the position of the positioning plate 3 needs to be adjusted, the user rotates the turntable 10, and the turntable 10 drives the bevel gear set 9 to rotate. The bevel gear set 9 also drives the second eccentric gear 8 to rotate. The second eccentric gear 8 drives the first eccentric gear 7 to rotate, and at the same time pushes the first eccentric gear 7 to move horizontally. The first eccentric gear 7 drives the moving member 6 to move horizontally. When the moving member 6 moves in the direction away from the second eccentric gear 8, the first spring is compressed, and at the same time, the moving plate 5 is driven to move. The moving plate 5 drives the positioning plate 3 to move through the first connecting member 4, thereby realizing rapid adjustment of the position of the positioning plate 3. The position adjustment is no longer performed in the direction of removing the bolts, which shortens the time required for adjustment and is easy to use.

[0052] The adjusting device further comprises: two sets of sliders 11; the two sets of sliders 11 are respectively arranged at the upper end and the lower end of the moving member 6, and are fixedly connected to the moving member 6, so as to restrict the moving member 6 to move only horizontally.

[0053] When sewing the cover, two kinds of fabrics need to be overlapped, and wrinkles appear between the fabrics during the sewing process, which need to be manually arranged, making it inconvenient to use.

[0054] In order to solve the above problem, this embodiment proposes an implementation method, where the automobile seat cover sewing and positioning device further includes: a flattening device; the flattening device is arranged on a side of the cavity away from the adjusting device, and is used to flatten the wrinkles on the cover.
