The guide member and the rotating shaft assembly are axially rotated together. One end of the guide member is provided with an edge-adjusting limiting end. The guide member is also provided with a wrench for driving the guide member to rotate up and down along the rotating shaft axis of the rotating shaft assembly. The guide member and the rotating shaft assembly are not perpendicular to each other. One end of the edge-adjusting limiting end on the guide member is inclined outward.

[0005] The rotating shaft assembly extends outward to form an extension end, and an elastic element is provided between the extension end and the wrench.

[0006] The elastic element is an elastic torsion spring or an elastic rubber ring.

[0007] A through groove is formed on the fixed end, and the rod-shaped structure of the rotating shaft assembly is inserted into the through groove. The relative position between the fixed end and the rotating shaft assembly is adjustable and fixed by fasteners.

[0008] The top of the fixed end is provided with a threaded hole, and the fastener is a bolt. The bolt cooperates with the threaded hole to fix the rotating shaft assembly in the through groove of the fixed end.

[0009] The rotating shaft assembly has a hinge shaft, and the guide member is hinged to the hinge shaft of the rotating shaft assembly and rotates in cooperation with the rotating shaft assembly.

[0010] The fixed end is provided with a mounting part for fixing the fixed end to the pressure foot of the roller carriage.

[0011] The mounting part has a U-shaped opening structure, and the mounting part with the U-shaped opening structure is fixedly connected to the pressure foot of the roller carriage by bolts.

[0012] The edge limiting end is located on the inner side of the end of the guide member.

[0013] A limiting block is formed on the extended end to prevent the elastic element from disengaging.

[0014] The beneficial effects of this utility model are as follows: This utility model provides a roller sewing edge guide, including a fixed end connected to the presser foot of the roller sewing machine, and a rotating shaft assembly. The rotating shaft assembly is detachably connected to the fixed end and its relative position is adjustable. The rotating shaft assembly is also provided with a guide member, which is axially rotatably engaged with the rotating shaft assembly. One end of the guide member is provided with an edge-limiting end, and the guide member is also provided with a wrench that drives the guide member to rotate up and down along the rotating shaft axis of the rotating shaft assembly. The guide member and the rotating shaft assembly are not perpendicular to each other. One end of the edge-limiting end on the guide member is inclined outward. This utility model achieves synchronous movement between the roller sewing edge guide and the presser foot by connecting the roller sewing edge guide to the presser foot of the roller sewing machine. The adjustable relative position between the rotating shaft assembly and the fixed end enables the function of adjusting the position and angle of the guide member on the rotating shaft assembly when sewing curved line segments.

[0018] 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.

[0019] A roller carriage edge guide includes a fixed end 1 connected to a presser foot of the roller carriage. The fixed end 1 has a mounting portion 12 for fixing the fixed end 1 to the presser foot. The mounting portion 12 has a U-shaped opening structure and is fixedly connected to the presser foot of the roller carriage by bolts. By mounting the edge guide on the presser foot of the roller carriage, synchronous movement of the edge guide and the presser foot is achieved. The carriage also includes a rotating shaft assembly 2, which is detachably connected to the fixed end 1 and whose relative position is adjustable. A through groove is formed on the fixed end 1, and the rod-shaped structure of the rotating shaft assembly 2 is inserted into the through groove. Fasteners 11 are used to adjust and fix the relative position between the fixed end 1 and the rotating shaft assembly 2. A threaded hole is provided at the top of the fixed end 1, and the fastener 11 is a bolt. The bolt engages with the threaded hole to fix the rotating shaft assembly 2 within the through groove of the fixed end 1. The adjustable relative position between the rotating shaft assembly and the fixed end enables the adjustment of the position and angle of the guide on the rotating shaft assembly when sewing curved line segments. The rotating shaft assembly 2 also includes a guide 3, which is axially rotatable with the rotating shaft assembly 2. One end of the guide 3 has a side-limiting end 31, which is located inside the end of the guide 3. The guide 3 also has a wrench 32 that drives it to rotate up and down along the rotating shaft of the rotating shaft assembly 2. The guide 3 is not perpendicular to the rotating shaft assembly 2. One end of the side-limiting end 31 on the guide 3 is tilted outwards to prevent it from interfering with the sewing machine needle when the guide 3 moves downwards.

[0020] The rotating shaft assembly 2 extends outward to form an extension end 21, and an elastic element 22 is provided between the extension end 21 and the wrench 32. The elastic element 22 is an elastic torsion spring or an elastic rubber ring.
