DETAILED DESCRIPTION

[0015] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", "vertical", "horizontal", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0017] like Figures 1 to 5As shown, the embodiment of the utility model includes a bottom plate 1 and a lower clamping plate 2, the bottom plate 1 is symmetrically provided with a plurality of positioning blocks 101 along the transverse central axis, the number of the lower clamping plates 2 is two, and the lower clamping plates 2 are provided with corresponding first positioning grooves 201, which cooperate with the positioning blocks 101 to position the lower clamping plates 2; the two lower clamping plates 2 are rotatably connected with the upper clamping plates 3 through the connecting member 4, and the lower clamping plates 2 and the upper clamping plates 3 cooperate to clamp the two sides of the material 7 to be sewn; the bottom of the upper clamping plate 3 is also provided with a corresponding second positioning groove 300 that cooperates with the positioning block 101 1, a template 6 is arranged in the middle of the upper clamp 3 through a connecting piece 4, and a mold groove 303 is arranged in the middle of the upper clamp 3, which is used to cooperate with the template 6 to form a three-dimensional shoe head sewing track; clamp quick clamps 102 are symmetrically arranged on the left and right sides of the bottom plate 1, which are used to press and fix the lower clamp 2 and the upper clamp 3; the bottom plate 1 is provided with a shoe head quick clamp 103, which is used to press the part of the material to be sewn 7 located outside the lower clamp 2 and the upper clamp 3; a pressing plate 5 connected to the moving axis of the computer sewing machine is arranged at the template 6, which is used to press the template 6 and drive the clamp to move.

[0018] As a preference, Figure 3 and 4 As shown, the lower clamping plate 2 is symmetrically provided with positioning protrusions 302, and the upper clamping plate 3 is symmetrically provided with positioning holes 302. The positioning protrusions 202 and the positioning holes 302 cooperate to position the lower clamping plate 2 and the upper clamping plate 3; Figure 5 As shown, the connecting member 4 is in the form of an adhesive tape.

[0019] When it is necessary to sew a three-dimensional toe cap, first place the material to be sewn 7 on the base plate 1, then place the two lower clamps 2 on the base plate 1, and position them by means of the positioning block 101 cooperating with the first positioning groove 201. The two lower clamps 2 are located on both sides of the material to be sewn 7 to wrap it, and then the upper clamp 3 presses both sides of the material to be sewn 7, and the part pressed by the template 6 is the shape of the three-dimensional toe cap; then the clamp quick clamp 102 presses the upper clamp 3, and the toe quick clamp 103 presses the head position of the material to be sewn 7, and then the computer sewing machine moving axis is controlled to drive the pressing plate 5 to move down and press the template 6. Since the table top of the computer sewing machine is a smooth plane, the computer sewing machine moving axis can drive the clamp to move through the pressing plate 6 to cooperate with the sewing needle to sew the shape of the three-dimensional toe cap.
