[0029] The technical solution of the present utility model will be further described below in conjunction with the embodiments and drawings.

[0030] Example 1

[0031] Please also refer to Figure 1 、 Figure 2 , Figure 1 This is a structural diagram of the special-shaped sewing template 1 disclosed in the first embodiment of the present utility model in the state where the pressing plate is pressed. Figure 2 This is a structural schematic diagram of the special-shaped sewing template 1 disclosed in the first embodiment of the present invention in the state where the pressing plate is open. The special-shaped sewing template 1 disclosed in this embodiment can be used in a sewing machine to achieve the splicing of special-shaped pieces. Specifically, the special-shaped sewing template 1 includes a base plate 10, a first pressing plate 11, and a second pressing plate 12. The base plate 10 is used to place the pieces. The base plate 10 is provided with a sewing groove 100 and a fixing needle 101. The sewing groove 100 includes a first groove section 100a and a second groove section 100b connected to each other. The second groove section 100b is a curved groove section, and the fixing needle 101 is located on the outer periphery of the curved groove section. The first pressing plate 11 is rotatably connected to the rotating end of the base plate 10. The first pressing plate 11 is arranged corresponding to the first groove section 100a. When the first pressing plate 11 is rotated to be pressed against the base plate 10, the end of the first pressing plate 11 away from the rotating end of the base plate 10 is located on the outer periphery of the first groove section 100a. The second pressing plate 12 can be rotatably connected to the rotating end of the base plate 10. The cross-sectional shape of the second pressing plate 12 is adapted to the second groove section 100b. A fixing hole 121 is provided on the second pressing plate 12. When the second pressing plate 12 is rotated to be pressed onto the base plate 10, the second pressing plate 12 is arranged corresponding to the second groove section 100b, and the fixing needle 101 is passed through the fixing hole 121.

[0032] Combine Figure 3As shown, using the shaped sewing template 1 of this embodiment, when splicing the straight portions of shaped pieces, one simply rotates the first pressing plate 11 open. First, the straight portion of the lower shaped piece 14a is placed on the base plate 10 according to the position of the first groove section 100a. Next, the upper shaped piece 14b is positioned according to the raw edges of the lower shaped piece 14a, ensuring that the raw edges of the upper shaped piece 14b overlap with those of the lower shaped piece 14a within the area covered by the first pressing plate 11. The first pressing plate 11 is then rotated until it presses against the base plate 10 to secure the shaped piece 14. After the shaped piece 14 is firmly pressed, the sewing machine can be used to sew the straight portions of the shaped piece 14. To join the curved portions of the shaped pieces, simply rotate the second pressing plate 12 open. Based on the position of the second slot section 100b, thread the raw edges of the curved portions of the lower and upper shaped pieces 14a, 14b through the fixing pins 101 to secure the shaped pieces. Then, rotate the second pressing plate 12 until it is pressed against the base plate 10 to compress the shaped pieces 14. The sewing machine can then be used to sew the curved portions of the shaped pieces 14. This method completes the sewing of the shaped pieces 14. After all the sewing of the shaped pieces 14 is complete, rotate the first and second pressing plates 11, 12 open, and remove the sewn pieces.

[0033] It can be seen from this that by using the special-shaped sewing template 1 of this embodiment, the first pressing plate 11 and the second pressing plate 12 can be used to press the special-shaped pieces. At the same time, the fixing holes 121 in the second pressing plate 12 and the fixing needles 101 on the base plate 10 can be used to fix the pieces, which can effectively prevent the deformation of the special-shaped pieces during the sewing process.

[0034] In some embodiments, the base plate 10 is a thin plate to improve the portability of the special-shaped sewing template 1. Alternatively, the base plate 10 is a thin plate in a square, circular, or other shape. It is understood that the base plate 10 only needs to be able to accommodate the special-shaped cutting piece 14, and the shape of the base plate 10 is not specifically limited in this embodiment.

[0035] Optionally, the thickness of the bottom plate 10 is 0.5 mm to 2 mm. Thus, the bottom plate is relatively light and thin, which can make the special-shaped sewing template as a whole lighter.

[0036] Optionally, to reduce the overall weight of the special-shaped sewing template 1, the base plate 10 can be made of plastic. Furthermore, to facilitate observation of sewing stitches and the placement of cut pieces by the sewing operator, the base plate 10 can be made of transparent plastic, such as PVC (Polyvinyl Chloride), PC (Polycarbonate), or acrylic. For example, the base plate 10 can be a transparent PVC plate with a thickness of approximately 1 mm.

[0037] In some embodiments, the sewing slot 100 includes multiple interconnected slot segments, allowing the seamstress to flexibly adjust the slot segments according to the size of the piece. For example, the sewing slot 100 includes a first slot segment 100a and a second slot segment 100b. The first slot segment 100a is divided into two sections, with the two first slot segments 100a located at either end of the second slot segment 100b.

[0038] In order to achieve sewing of a variety of different shaped pieces, the sewing slot 100 may include slot segments of different shapes, which can be used for sewing pieces of different shapes. Optionally, the slot segment may be linear, arc-shaped or other shapes. Exemplarily, the first slot segment 100a is a linear slot segment, the second slot segment 100b is an arc-shaped slot segment, and the second slot segment 100b is smoothly connected between the two first slot segments 100a. It is understandable that in other examples, the first slot segment may also be set to three, four or more segments, and the first slot segments may all be linear slot segments, or some of the first slot segments may be linear slot segments and other first slot segments may be curved slot segments. The specific setting can be based on actual needs, and this embodiment does not specifically limit this.

[0039] In some embodiments, an anti-slip structure is provided on one edge of the base plate 10 along the first and second groove sections 100a, 100b. The anti-slip structure is used to prevent the cut pieces from sliding during sewing. Optionally, the anti-slip structure can be made of sandpaper, tape, sponge, or other anti-slip materials.

[0040] In some embodiments, to further secure the position of the cut piece, the base plate 10 is further provided with a fixing pin 101 with the needle pointing upward. To enable the fixing pin to penetrate the base plate for securing, the fixing pin 101 is a metal pin. Alternatively, the fixing pin 101 may be a thumbtack, a pin, or other metal pin. It will be appreciated that the fixing pin 101 only needs to be able to penetrate the cut piece to secure it, and the type of the fixing pin 101 is not specifically limited in this embodiment.

[0041] Alternatively, this fixing pin 101 can be bonded on the base plate by glue so that the fixing pin remains fixed.Certainly, as other examples, this fixing pin also can be bonded on the base plate by, for example, adhesive tape.

[0042] In some embodiments, the first pressure plate 11 and the base plate 10 can be rotatably connected by one or more methods such as a hinge structure or tape bonding, so that the relative positions of the first pressure plate 11 and the base plate 10 are fixed in the pressed state, simplifying manual operation and helping to improve the relative position accuracy of the first pressure plate 11 and the base plate 10 in the pressed state.

[0043] Optionally, in order to enable the pressing plate to press the cut piece in the pressed state, when the first pressing plate 11 rotates to press against the bottom plate 10, the first pressing plate 11 is at least partially pressed against the first slot section 100a. That is, the first pressing plate 11 at least partially covers the first slot section 100a.

[0044] Optionally, the first pressing plate 11 is a thin plate to improve the portability of the special-shaped sewing template 1. For example, the first pressing plate 11 can be a thin plate having a square, curved, or other shape. It is understood that the first pressing plate 11 is compatible with the first slot section 100a. Since the shape of the first slot section 100a can be adjusted according to the shape of the special-shaped piece, the shape of the first pressing plate 11 only needs to match the first slot section 100a and be able to press and secure the special-shaped piece 14 when pressed against the base plate 10. The shape of the first pressing plate 11 is not specifically limited in this embodiment.

[0045] Optionally, the thickness of the first pressing plate 11 is 0.5 mm to 2 mm, so that the first pressing plate 11 can fully press and fix the cut piece. The thickness of the first pressing plate can be, for example, 1 mm, 1.5 mm, etc.

[0046] Optionally, to reduce the overall weight of the special-shaped sewing template 1, the first pressing plate 11 can be made of plastic. Furthermore, to facilitate observation of the sewing stitches and the placement of the cut pieces by the sewing operator, the first pressing plate 11 can be made of transparent plastic, such as PVC (Polyvinyl Chloride), PC (Polycarbonate), or acrylic. For example, the first pressing plate 11 can be a transparent PVC plate with a thickness of approximately 1 mm.

[0047] In some embodiments, to facilitate sewing of relatively large pieces, the first pressing plates 11 are provided in multiple numbers. For example, there are two first pressing plates 11, each corresponding to one of the two first slot segments 100a. Of course, in other embodiments, the first pressing plates 11 may be provided in three, four, or even more numbers. Specifically, the number of first pressing plates may be set in accordance with the number of first slot segments, and the number of first pressing plates and first slot segments may be set based on actual needs, which is not specifically limited in this embodiment.

[0048] In some embodiments, a second pressing plate 12 is disposed between the two first pressing plates 11 and corresponding to the second groove section 100b. The second pressing plate 12 is used to press the irregularly shaped portion of the irregularly shaped piece to prevent the irregularly shaped piece from deforming during sewing.

[0049] Optionally, the second pressing plate 12 and the base plate 10 can be rotatably connected by one or more methods such as a hinge structure or tape bonding, so that the relative positions of the second pressing plate 12 and the base plate 10 are fixed in the pressed state, simplifying manual operation and improving the relative position accuracy of the second pressing plate 12 and the base plate 10 in the pressed state.

[0050] Optionally, in order to enable the pressing plate to press the cut piece in the pressed state, when the second pressing plate 12 rotates to press against the bottom plate 10, the second pressing plate 12 at least partially presses against the second groove section 100b. That is, the second pressing plate at least partially covers the second groove section.

[0051] Optionally, the second pressing plate 12 is a thin plate to improve the portability of the special-shaped sewing template 1. For example, the thickness of the first pressing plate 11 is 0.5 mm to 2 mm, so that the first pressing plate 11 can fully press and fix the cut pieces. The thickness of the second pressing plate can be, for example, 1 mm, 1.5 mm, etc.

[0052] Optionally, to reduce the overall weight of the special-shaped sewing template 1, the second pressing plate 12 can be made of plastic. Furthermore, to facilitate observation of the sewing stitches and the placement of the cut pieces by the sewing operator, the second pressing plate 12 can be made of transparent plastic, such as PVC (Polyvinyl Chloride), PC (Polycarbonate), or acrylic. For example, the second pressing plate 12 can be a transparent PVC plate with a thickness of approximately 1 mm.

[0053] In some embodiments, in order to achieve sewing of pieces of different shapes, the second pressing plate 12 can have different shapes. Optionally, the second pressing plate 12 can be a thin plate of square, arcuate, or other shapes. Exemplarily, the second pressing plate 12 is a curved plate. It is understood that the shape of the second pressing plate 12 and the shape of the second slot section 100b can be interchanged according to the shape of the special-shaped piece. The shape of the second pressing plate 12 only needs to be compatible with the second slot section 100b and be able to press and secure the special-shaped piece 14 when pressed against the base plate 10. The shape of the second pressing plate 12 is not specifically limited in this embodiment.

[0054] In some embodiments, the second pressing plate 12 includes opposing rotating ends and free ends. The free end has a curved surface that mates with the second slot segment 100b and conforms to the outer periphery of the second slot segment. The free end is rotatably connected to the base plate and has a pressing surface configured to press the cut piece. This curved surface conforms to the shape of the cut piece and, when the second pressing plate 12 is rotated to press against the base plate 10, can press and secure the irregularly shaped edges of the cut piece, preventing deformation of the cut piece during sewing, which could result in wrinkles in the finished cut piece.

[0055] Combine Figure 4 and Figure 5 As shown, in some embodiments, the second pressing plate 12 includes a rotating end 12b and a free end 12a. The rotating end 12b is rotatably connected to the base plate 10. When the second pressing plate 12 is rotated to be pressed against the base plate 10, the free end 12a is pressed against the second groove section 100b. The free end 12a is provided with a fishbone 120. The fishbone 120 is used to press the cut piece, thereby further preventing the cut piece from wrinkling during sewing.

[0056] Optionally, to ensure that the fishbone spur covers the groove section, the protruding height of the fishbone spur 120 is less than or equal to the width of the second groove section 100b. For example, if the width of the second groove section 100b is 3 mm and the protruding height of the fishbone spur 120 is 2 mm, the fishbone spur 120 can cover the second groove section 100b. In other words, the protruding height of the fishbone spur can be set based on the width of the second groove section, and this embodiment does not specifically limit this.

[0057] Optionally, to reduce the overall weight of the special-shaped sewing template 1, the fishbone 120 can be made of plastic. Furthermore, to facilitate observation of the sewing seam and the placement of the cut pieces, the fishbone 120 can be made of a transparent plastic, such as PVC (Polyvinyl Chloride), PC (Polycarbonate), or acrylic. For example, the fishbone 120 can be a transparent PVC sheet approximately 1 mm thick.

[0058] Combine Figure 6 As shown, in some embodiments, the fishbone thorn 120 includes a mesh portion 120a and a fishbone portion 120b, the mesh portion 120a is provided at the free end 12a of the second pressure plate 12, the fishbone portion 120b is connected to the mesh portion 120a, and the fishbone portion 120b protrudes toward the outside of the second pressure plate 12, and when the second pressure plate 12 is rotated to be pressed onto the bottom plate 10, the fishbone portion 120b covers the second groove section 100b.

[0059] In some embodiments, the grid portion 120 a may be connected to the free end 12 a of the second pressing plate 12 by adhesive tape, thereby fixing the relative positions of the grid portion 120 a and the second pressing plate 12 .

[0060] In some embodiments, in order to further fix the cut piece, the second pressing plate 12 is further provided with a fixing hole 121, and the fixing hole 121 is arranged corresponding to the fixing needle 101, so that when the second pressing plate is pressed onto the bottom plate, the fixing needle on the bottom plate can be inserted into the fixing hole.

[0061] Optionally, in order to allow the fixing needle to pass through the fixing hole to fix the cut piece, the diameter of the fixing hole 121 may be in the range of 2mm-3mm. That is, the diameter of the needle tip of the fixing needle is less than or equal to 2mm-3mm.

[0062] The following is a brief description of the process of sewing special-shaped pieces using the special-shaped sewing template of the present application:

[0063] When using the special-shaped sewing template 1 to sew special-shaped pieces, the first and second pressing plates 11 and 12 are first opened, and the lower special-shaped piece 14a is placed on the base plate 10 according to the position of the first groove section 100a and the positioning line (provided on the base plate for positioning the piece on the base plate). Next, the raw edge of the upper special-shaped piece 14b is aligned with the raw edge of the lower special-shaped piece 14a and is stacked on the lower special-shaped piece 14a. Then, the first pressing plate 11 is rotated to press against the base plate to press and fix the upper special-shaped piece 14b and the lower special-shaped piece 14a together. After that, sewing can be carried out using a sewing machine. Then, sew the remaining parts of the special-shaped pieces. When it is necessary to sew the curved parts of the pieces, pass the curved parts of the lower special-shaped piece 14a and the upper special-shaped piece 14b through the fixing needles 101 on the bottom plate 10. Then, rotate the second pressing plate 12 to press it onto the bottom plate 10, and pass the fixing holes 121 on the second pressing plate 12 through the fixing needles 101. After that, you can use the sewing machine to sew.

[0064] The special-shaped sewing template 1 disclosed in the first embodiment of the present invention has a simple structure and can prevent the pieces from being deformed during the sewing process, which is conducive to reducing the difficulty of splicing special-shaped pieces.
