Description

Technical Field

[0001] This utility model relates to the field of handmade leather processing technology, specifically a handheld knife for hand-stitching holes in leather. Background Technology

[0002] Completing a piece of handmade leather goods is a complex and meticulous process, requiring perfection in every step to create a flawless piece. Leather goods are typically assembled using sewing, but due to the thickness and stiffness of leather, the necessary stitching holes must be pre-drilled for the stitching.

[0003] Existing leather stitching tools generally consist of a gap wheel with multiple serrated blades and a handle. When in use, the user can roll the gap wheel against the surface of the leather to leave straight or curved stitching traces on the surface of the leather.

[0004] Existing leather sewing tool tools on the market generally adjust the depth of the sewing hole by changing the blade size, which is rather cumbersome. Therefore, there is an urgent need to develop a handheld tool for hand-sewing leather holes to meet practical needs. Utility Model Content

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A handheld knife for hand-stitching seams in leather includes a handle, an adjusting baffle, and a fixing assembly. One end of the handle has a rotatable clearance wheel, and the end of the handle away from the clearance wheel is a grip. The adjusting baffle is movably disposed on one side of the handle and is located at the end of the handle near the clearance wheel. The fixing assembly includes a first fixing nut and a second fixing nut. The adjusting baffle has a first clearance hole and a second clearance hole in its middle. The handle has a first mounting hole and a second mounting hole in its middle that match the first fixing nut and the second fixing nut. The first fixing nut and the second fixing nut pass through the first clearance hole and the second clearance hole respectively and are threadedly connected to the first mounting hole and the second mounting hole. The diameter of the first clearance hole and the second clearance hole is larger than the diameter of the first mounting hole and the second mounting hole.

[0008] As a further solution, the end of the adjusting baffle near the gap wheel is an arc-shaped limiting plate that can move horizontally on its plane.

[0009] As a further scheme in the above description, a plurality of cutting edges are arranged in a circumferential array at the periphery of the gap wheel.

[0010] As a further scheme in the above description, a plurality of cutting edges are arranged in a circumferential array at the periphery of the gap wheel.

[0011] As a further scheme in the above description, a plurality of cutting edges are arranged in a circumferential array at the periphery of the gap wheel.

[0012] As a further scheme in the above description, a plurality of cutting edges are arranged in a circumferential array at the periphery of the gap wheel.

[0013] The beneficial effects of the present application are as follows:

[0014] The handheld cutter for handcrafting a leather sewing line hole according to the present application has the following advantages: the adjusting baffle is arranged at one end of the cutter handle close to the gap wheel, and the middle part of the adjusting baffle is provided with a first clearance hole and a second clearance hole with a larger hole diameter than the first mounting hole and the second mounting hole, so that the adjusting baffle can be moved up and down or left and right on the plane; on the one hand, the adjusting baffle can adjust the limiting height between the edge and the leather, thereby achieving the function of adjusting the line hole depth of the gap wheel; on the other hand, this structure can satisfy the effect of adjusting the hole depth when the user holds horizontally or vertically, and has stronger applicability.
