Description
Technical Field
[0001] The utility model belongs to the technical field of cutting tools and relates to a double-edged carving knife for carving grooves on shoe and boot design patterns. Background Art
[0002] Before mass production, footwear needs to go through design and sample making stages. For many types of footwear, different materials are used to make the uppers. When sewing different materials together, one material needs to be pressed onto the other at the joint, and then sewn together at the overlapping area. During sewing, the stitching position needs to be determined by lines pre-drawn by the designer. The designer uses a grooved pattern to guide the drawing of these lines.
[0003] Because the number of prototypes made during the design phase is small, designers often use cardboard as templates and manually carve grooves with a carving knife. When carving, designers need to use a single-edged carving knife to carve two similar curves about 2mm apart, following guide lines drawn on the template, ultimately forming a 2mm wide hollow groove. Later, the template with the hollow groove is placed on the shoe upper fabric, and a marking pen tip is placed inside the groove to draw lines under its constraint. It can be seen that the above method of carving grooves with a single-edged carving knife is time-consuming, labor-intensive, and has a high error rate. Summary of the Invention
[0004] The purpose of the utility model is to provide a double-edged carving knife for carving grooves on a shoe design pattern, so as to improve the efficiency and accuracy of carving grooves on the pattern.
[0005] In order to achieve the above-mentioned purpose, the technical solutions adopted by the present invention are as follows:
[0006] A double-edged carving knife for carving grooves on shoe and boot design patterns comprises a handle and a carving knife arranged on the handle and detachably connected to the handle. The carving knife is a double-edged carving knife formed by stacking two blades, and a spacer component is arranged between the two blades; the spacing between the two blades of the double-edged carving knife is the same as the width of the groove carved on the pattern.
[0007] As a limitation, the spacer assembly is composed of a plurality of stacked sheet-like spacers;
[0008] The double-edged carving knife and the spacer are clamped by a clamping member provided with a clamping gap;
[0009] The outer shell of the clamping piece is provided with a sleeve, and the sleeve is detachably connected to the handle.
[0010] As a further limitation, the sleeve is hollow, open at both ends, and provided with an internal thread at the lower portion, and the lower portion of the clamping member and the upper portion of the handle are both provided with external threads that match the internal thread.
[0011] As a definition of the clamping slit, the clamping slit includes a first clamping slit and a second clamping slit of different widths, both of which are arranged along the length direction of the clamping member.
[0012] As a further definition of the clamping slit, in a cross section of the clamping slit, the first clamping slit and the second clamping slit are cross-intersecting.
[0013] As a limitation of the sleeve, the outer surface of the sleeve is provided with anti-slip protrusions.
[0014] As a second limitation, the double-edged carving knife for carving grooves in shoe and boot design patterns further includes a carving knife protective cover.

[0029] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0030] Example: Double-edged carving knife for carving grooves on shoe design patterns
[0031] like Figures 1 to 4 As shown, this embodiment includes a handle 1 and a carving knife disposed on and detachably connected to the handle 1. The carving knife is a double-edged carving knife 2 formed by stacking two blades, with a spacer component 3 disposed between the two blades. The distance between the two blades of the double-edged carving knife 2 is the same as the width of the groove in the template.
[0032] like Figure 2 As shown, the spacer assembly 3 is composed of a plurality of stacked sheet-like spacers. In this embodiment, the spacers are made of metal sheets with the same thickness as the blade.
[0033] The double-edged carving knife 2 and the spacer are held by a clamping member 4 with a clamping slot. A sleeve 5 is fitted over the clamping member 4, and the sleeve 5 is detachably connected to the handle 1. The outer surface of the sleeve 5 is provided with anti-slip protrusions.
[0034] Specifically, the sleeve 5 is hollow, open at both ends, and has an internal thread at the bottom. The lower part of the clamping member 4 and the upper part of the handle 1 are both provided with external threads that are compatible with the internal threads. Here, compatibility means that the sleeve 5, the clamping member 4, and the handle 1 can achieve a threaded connection.
[0035] like Figure 3 and Figure 4As shown, the clamping seams include a first clamping seam 41 and a second clamping seam 42 with different widths, both of which are arranged along the length of the clamping member 4. Furthermore, in the cross-section of the clamping seams, the first clamping seam 41 and the second clamping seam 42 intersect in a cross shape. In this way, the same clamping member 4 can be used for two different sizes of double-edged carving knives 2.
[0036] To protect the double-edged carving knife 2 from damage and to enhance safety, this invention further includes a protective sleeve for the carving knife. When not in use, the protective sleeve can be simply placed over the double-edged carving knife 2.
[0037] The method of using this embodiment is as follows: the designer draws two adjacent slotting guide lines on the template in advance according to the width of the slots to be slotted on the template; then, based on the spacing between the two slotting guide lines, selects a clamping member 4 whose first clamping slit 41 or second clamping slit 42 has the same width as the spacing; then, adjusts the number of spacers to form a spacing assembly 3, which is further placed between two blades to form a double-edged carving knife 2, and the double-edged carving knife 2 is placed in the corresponding clamping slit; then, the clamping member 4 is sleeved in the sleeve 5, and the sleeve 5, the clamping member 4, and the handle 1 are further assembled together; finally, the slots are cut along the slotting guide lines drawn on the template. During the slotting process, the two blades of the double-edged carving knife 2 exactly correspond to the two slotting guide lines, and the designer can carve a hollow groove that meets the requirements in one go.
