[0021] The present invention will be described in detail here by way of example.

[0022] Example 1:

[0023] This embodiment provides a lapel sewing auxiliary tool; see [link / reference]. Figures 1 to 4 This lapel sewing auxiliary tool includes an upper clamping plate 1, a middle clamping plate 2, and a lower clamping plate 3. Both the upper clamping plate 1 and the lower clamping plate 3 can rotate and open relative to the middle clamping plate 2. In this embodiment, the upper clamping plate 1, the middle clamping plate 2, and the lower clamping plate 3 are all transparent plastic sheets, which are low-cost and easy for operators to observe. In this embodiment, three single-sided adhesive strips 4 are used to connect the upper clamping plate 1, the middle clamping plate 2, and the lower clamping plate 3 in pairs, allowing both the upper clamping plate 1 and the lower clamping plate 3 to rotate and open relative to the middle clamping plate 2. Using single-sided adhesive strips to connect the three clamping plates in pairs is low-cost and easy to assemble. Those skilled in the art can modify the connection method of the upper, middle, and lower clamping plates to achieve rotation and opening of both the upper and lower clamping plates relative to the middle clamping plate through other connection methods.

[0024] The upper layer 1, middle layer 2, and lower layer 3 are all provided with sewing clearance holes A, see [reference]. Figure 5 The sewing clearance hole A corresponds to the outer contour A1 of the lapel. The upper layer plate 1, the middle layer plate 2 and the lower layer plate 3 are all provided with marking clearance holes B. The marking clearance holes B correspond to the inner contour B1 of the lapel. Both the sewing clearance hole A and the marking clearance hole B are holes that pass through the plate along the thickness direction of the plate. The interlayer, the outer collar and the bottom collar are sewn together along the sewing clearance hole A. The sewing trajectory on the lapel for docking with the collar stand is drawn along the marking clearance hole B.

[0025] Multiple ease control blocks C are provided on the lower side of the upper layer 1 and the upper side of the middle layer 2. The ease control blocks C are distributed at intervals along the sewing clearance holes A. When the upper layer 1 and the middle layer 2 are closed, the ease control blocks C on the lower side of the upper layer 1 and the ease control blocks C on the upper side of the middle layer 2 are alternately arranged. In this embodiment, the ease control blocks C are made of yellow foam material with adhesive on one side.

[0026] The lower clamping plate 3 has a collar alignment line on its upper side, facilitating precise placement of the collar on the lower clamping plate 3 by the operator. The middle clamping plate 2 has a face collar alignment line on its upper side, facilitating precise placement of the face collar on the middle clamping plate 2 by the operator. In this embodiment, the collar alignment line is formed by a collar limiting strip 31 fixed to the upper side of the lower clamping plate 3, and the face collar alignment line is formed by a face collar limiting strip 21 fixed to the upper side of the middle clamping plate 2. The collar limiting strip 31 and the face collar limiting strip 21 are made of red foam material, with adhesive on one side, and are adhered to the clamping plates. Those skilled in the art can modify the method of forming the collar alignment lines and the face collar alignment lines, for example, by engraving the alignment lines on the clamping plates.

[0027] In this embodiment, the upper side of the middle layer plate 2 is provided with two slack control strips 22, which are located between the sewing clearance hole A and the marking clearance hole B on the middle layer plate 2. The upper layer plate 1 is provided with arc-shaped clearance holes 11 corresponding to the slack control strips 22. The slack control strips 22 are made of yellow foam material, with adhesive on one side, and are stuck to the plate. Those skilled in the art can adjust the number, thickness, and shape of the slack control strips 22, and adjust the number, thickness, and position of the slack control blocks C as needed.

[0028] In this embodiment, anti-slip strips D are provided on the upper side of the lower layer 3, the upper side of the middle layer 2, and the lower side of the upper layer 1. Only two anti-slip strips D on the upper side of the lower layer 3 are shown in the figure. The function of the anti-slip strips D is to prevent the interlayer, collar, and bottom collar from shifting. Those skilled in the art can design the position of the anti-slip strips D as needed. For example, anti-slip strips can be provided along the marked clearance hole B on the lower side of the upper layer 1, and along the sewing clearance hole A and the marked clearance hole B on the upper side of the middle layer 2. The anti-slip strips D can have one side with adhesive and the other side with a frosted surface, with the adhesive side attached to the interlayer. Alternatively, the anti-slip strips D can have adhesive on both sides; those skilled in the art can choose according to their needs.

[0029] In this embodiment, to prevent relative displacement between the interlayer, the outer collar, and the bottom collar, the upper clamping plate 1 is provided with multiple fixing nails 12. Each fixing nail 12 has an L-shaped nail head. When the upper clamping plate 1 and the middle clamping plate 2 are closed, the multiple nail heads are spaced apart along the marked clearance holes B on the middle clamping plate 2. Each fixing nail 12 has a T-shaped nail tail. Multiple fixing plates 13 are adhered to the upper clamping plate 1, with each fixing plate 13 corresponding to a fixing nail 12. The fixing plates 13 fix the nail tails of the corresponding fixing nails 12 to the upper clamping plate 1. The T-shaped nail tails of the fixing nails 12 make them less prone to movement under the fixation of the fixing plates 13. In this embodiment, the fixing nail 12 is formed by bending a metal needle, which is easy to process. See [reference needed]. Figure 6 The blunt end of the metal needle is C-bent to form a T-shaped nail tail, see [reference]. Figure 7 The tip of the metal needle is bent into an L-shape to form an L-shaped nail head; those skilled in the art can design the nail tail of the fixing nail into other structures.

[0030] The method for using this lapel sewing aid is as follows:

[0031] Flip open the upper layer 1 and the middle layer 2 together, place the bottom collar on the upper side of the lower layer 3, flip the middle layer 2 back, so that the bottom collar is sandwiched between the middle layer 2 and the lower layer 3, and draw a line on the bottom collar along the line marking hole B on the middle layer 2.

[0032] Place the collar on the upper side of the middle layer plate 2, flip the upper layer plate 1 back, so that the collar is sandwiched between the upper layer plate 1 and the middle layer plate 2. Then, flip the upper layer plate 1, the collar and the middle layer plate 2 together, and draw a line on the collar along the line marking hole B on the middle layer plate 2.

[0033] Flip the upper plywood 1, the collar, and the middle plywood 2 back together;

[0034] Flip open the upper layer 1, place the interlayer on the collar, and then flip the upper layer 1 back so that the interlayer and the fabric are sandwiched between the upper layer 1 and the middle layer 2.

[0035] Sew the interlayer, outer collar, and bottom collar together along the sewing relief hole A. Then, turn the upper panel 1 over and pull the sewn interlayer, outer collar, and bottom collar down through the sewing relief hole A on the middle panel 2 to carry out the subsequent sewing work.

[0036] Example 2:

[0037] This embodiment provides a lapel sewing auxiliary tool; see [link / reference]. Figure 8 The difference between this lapel sewing aid and Embodiment 1 lies in the middle layer plate. In this embodiment, the upper side of the middle layer plate is provided with three ease control strips 22, one shorter and two longer, with the shorter ease control strip 22 stacked on top of the longer ease control strip 22. Those skilled in the art can replace the stacked long and short ease control strips with an irregularly shaped ease control strip.

[0038] In addition, to solve the problem of excessive excess at both ends of the lapel, the middle layer plate is provided with ease allowance holes 23 corresponding to both ends of the lapel. The ease allowance holes 23 correspond to the ease control blocks C at the corresponding positions on the lower side of the upper layer plate 1, so that the two ends of the lapel have more space.
