DETAILED DESCRIPTION

[0019] In order to further understand the invention content, characteristics and effects of the utility model, the following examples are given, and the detailed description is given as follows with reference to the drawings.

[0020] The structure of the utility model is described in detail below with reference to the drawings.

[0021] As Figures 1 to 4 shown, the utility model embodiment provides an auxiliary limiting assembly for sewing machine, including workbench 1, extension table 2, extension arm 3, connecting groove 4 and fixed structure 5, the top of workbench 1 is fixedly connected with sewing machine 101, the bottom of workbench 1 is fixedly connected with support frame 102, the left side of support frame 102 is slidably connected with extension arm 3, the left side of workbench 1 is rotatably connected with extension table 2 through pivot, the bottom of extension table 2 is fixedly connected with positioning strip 6, the left side of the inner wall of positioning strip 6 is fixedly connected with positioning block 601, positioning groove 602 is formed in the right side of positioning block 601, the left end of extension arm 3 is inserted into the inner wall of positioning strip 6, connecting groove 4 is formed in the left side of extension arm 3, positioning block 601 is inserted into the inner wall of connecting groove 4, the bottom of the right end of extension arm 3 is provided with sliding groove 7, the front and rear sides of the inner wall of connecting groove 4 are fixedly connected with sliding rod 401, and fixed structure 5 is arranged on the inner wall of connecting groove 4.

[0022] Reference Figure 2 and Figure 4 , fixed structure 5 includes sliding block 8, sliding block 8 is arranged at the bottom of the right end of extension arm 3, the outer surface of sliding block 8 is slidably connected to the inner wall of sliding groove 7, the bottom of sliding block 8 is fixedly connected with pressing block 9, and the top of sliding block 8 is fixedly connected with extrusion rod 10.

[0023] The above scheme is adopted: by setting sliding block 8, when pressing block 9 is pressed to the left, sliding block 8 can be driven to slide left along the inner wall of sliding groove 7, so as to drive extrusion rod 10 to move left synchronously.

[0024] Reference Figure 4 , extrusion rod 10 is arranged on the inner wall of connecting groove 4, the bottom of extrusion rod 10 is fixedly connected with sliding block 8, and rotary arm 11 is arranged on the front and rear sides of extrusion rod 10.

[0025] The above scheme is adopted: by setting extrusion rod 10, extrusion rod 10 can be driven by sliding block 8 to move left in connecting groove 4, so that extrusion rod 10 drives the rotation of two rotary arms 11 respectively during the movement.

[0026] Reference Figure 4Two rotating arms 11 are arranged on the inner wall of the connecting groove 4 in front and back, respectively. The ends of the two rotating arms 11 close to each other are rotatably connected to the upper and lower sides of the inner wall of the connecting groove 4 through rotating shafts, respectively. The sides close to each other of the ends of the two rotating arms 11 far away from each other are respectively attached to the outer surface of the extrusion rod 10. The ends of the two rotating arms 11 close to each other are fixedly connected with pressure arms 12, respectively.

[0027] By adopting the above scheme, the extrusion rod 10 extrudes the surfaces of the two rotating arms 11 close to each other when moving to the left, so that the two rotating arms 11 are forced to rotate relatively, thereby driving the two pressure arms 12 to rotate, respectively.

[0028] With reference to Figure 4 The two pressure arms 12 are fixedly connected to the sides of the two rotating arms 11 far away from the extrusion rod 10. The surfaces of the two pressure arms 12 are respectively provided with pressure grooves 13. The inner walls of the two pressure grooves 13 are respectively sleeved with driven rods 14. The sides of the two driven rods 14 far away from the extrusion rod 10 are fixedly connected with driven arms 15, respectively.

[0029] By adopting the above scheme, the two pressure arms 12 can extrude the two driven rods 14 through the pressure grooves 13 during rotation, so that the two driven rods 14 are forced to move close, thereby driving the two driven arms 15 to move close.

[0030] With reference to Figure 4 The middle parts of the two driven arms 15 are respectively slidably connected to the outer surface of a sliding rod 401. The sides of the two driven arms 15 close to each other are fixedly connected with positioning springs 16. The positioning springs 16 are sleeved on the outer surface of the sliding rod 401. The sides of the two driven arms 15 far away from the driven rods 14 are fixedly connected with limiting blocks 17, respectively.

[0031] By adopting the above scheme, the two driven arms 15 are driven by the driven rods 14 to slide close to the surface of the sliding rod 401 and extrude the compression of the positioning springs 16. The sliding of the two driven arms 15 drives the two limiting blocks 17 to move close.

[0032] With reference to Figure 4 The two limiting blocks 17 are fixedly connected to the sides of the two driven arms 15 far away from each other in front of and behind the ends close to the positioning block 601. The ends of the two limiting blocks 17 far away from each other are respectively inserted into the inner walls of positioning grooves 602.

[0033] By adopting the above scheme, when the two limiting blocks 17 move close, they can respectively disengage from the positioning grooves 602 to release the fixed limiting of the positioning block 601, thereby releasing the fixed connection between the extension arm 3 and the positioning strip 6, so that the extension table 2 can be put down.

[0034] In use, the automobile interior material to be processed is placed on the workbench 1, and then the sewing machine 101 is used for processing. When the automobile interior material is large, the extension table 2 is flipped up to be at the same horizontal plane as the workbench 1, the extension arm 3 is pushed to the left so that the left end slides into the inner wall of the positioning strip 6, and the positioning block 601 can be inserted into the connecting groove 4. During the movement, the positioning block 601 extrudes the surfaces of the two limiting blocks 17, so that the two limiting blocks 17 move and drive the two driven arms 15 to slide on the sliding rod 401 to be close to each other and extrude the positioning spring 16 to be compressed. When the positioning block 601 is completely inserted into the connecting groove 4, the positioning spring 16 drives the two driven arms 15 to slide, drives the two limiting blocks 17 to move and be inserted into the positioning groove 602, and fixes and limits the positioning block 601, so as to fix and connect the extension arm 3 and the positioning strip 6, support the extension table 2, and increase the use area of the workbench 1 and the extension table 2. The user can assist in sewing and processing the large automobile interior material. After the processing is completed, the pressing block 9 can be slid to the left, drive the sliding block 8 to slide to the left in the sliding groove 7, and simultaneously drive the extrusion rod 10 to move to the left in the connecting groove 4. The extrusion rod 10 moves to the left while extruding the surfaces of the two rotary arms 11, so that the two rotary arms 11 relatively rotate and drive the two pressure arms 12 to synchronously rotate. During the rotation of the two pressure arms 12, the two pressure arms 12 extrude the two driven rods 14 through the pressure groove 13, so as to drive the two driven arms 15 to respectively slide on the sliding rod 401 to be close to each other. At the same time, the two limiting blocks 17 are driven to move to be close to each other, are separated from the positioning groove 602, and are released from the fixing and limiting of the positioning block 601. Then, the extension arm 3 is slid to the right, so that the extension arm 3 is separated from the positioning strip 6 and slides back into the support frame 102, the fixing and connecting between the extension arm 3 and the positioning strip 6 is released, and the extension table 2 can be placed down.

[0035] In summary, the auxiliary limiting assembly of the sewing machine solves the problem that, in the process of processing automobile interiors, large leather raw materials are used to ensure the wrapping property of the interiors. If the area of the operation table is small, the operator may not accurately align and fix the raw materials, thereby affecting the precision and aesthetics of sewing.
