Description

Technical Field

[0001] The utility model relates to the technical field of seal carving knives, in particular to a hidden portable seal carving knife. Background Art

[0002] A seal cutting knife is a common carving knife, mainly used in traditional Chinese seal cutting art. It is a tool used to carve seal patterns, usually composed of a wooden handle and a steel knife, that is, a flat knife with the blade in the middle of the knife. The characteristics of a seal cutting knife are sharpness and thin blade, which is suitable for fine carving work. A seal cutting knife has many uses. It is an important tool for making seals, carving seal carving works, carving seal script and running script copybooks, making handicrafts and decorations, as well as education and training.

[0003] In the prior art, the seal carving knives on the market need to be equipped with a cover to protect the knife head or prevent scratches. The split cover is easy to lose, and each seal carving knife is limited by the direct connection between itself and the knife rod. A single seal carving knife only corresponds to one seal carving knife head and does not have multiple styles, so it is not very applicable. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and provides a hidden portable seal carving knife.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a hidden portable seal carving knife, comprising a knife bar, one end of which is fixedly connected to a storage bin, a knife head is placed inside the storage bin, and a second threaded joint is threadedly connected to the top of the storage bin;

[0006] One end of the cutter head is fixedly connected to a cutting edge, the other end of the cutter head is fixedly connected to a connecting portion, one end of the connecting portion is fixedly connected to a first threaded joint, and the outer surface of the first threaded joint is threadedly engaged with the inner wall of the second threaded joint, and the cutter head can be replaced through the threaded connection between the first threaded joint and the second threaded joint.

[0007] Furthermore, one end of the second threaded joint is fixedly connected to a rotating handle, and the rotating handle is a spherical structure.

[0008] Furthermore, an inner wall of the second threaded joint is provided with an internal thread matching the first threaded joint, and notches are symmetrically provided at one end of the second threaded joint away from the turning handle.

[0009] Furthermore, the two notches are located on the same straight line, and the widths of the two notches match the thickness of the blade.

[0010] Furthermore, one end of the knife rod away from the storage bin is fixedly connected with another rotating handle.

[0011] Furthermore, a storage cavity matching the cutter head and the second threaded joint is provided inside the storage bin.

[0012] Furthermore, the outer surface of the storage bin is surrounded by six faces to form a regular hexagonal structure.

[0013] The utility model has the following beneficial effects:

[0014] When the utility model is in use, the hidden portable seal engraving knife with replaceable blade head can realize the transformation between the use state and the idle state through the installation of the storage bin, the first threaded joint and the second threaded joint, in which the blade head is hidden in the storage bin and in which the blade head can be freely assembled at the end of the storage bin in the use state, and at the same time, the second threaded joint can be configured with blade heads of different styles for seal engraving, which is more applicable.

[0021] Figures 1 to 4 As shown, it relates to a hidden portable seal carving knife, including a knife bar 1, one end of the knife bar 1 is fixedly connected to a storage bin 2, a knife head 3 is placed inside the storage bin 2, and a second threaded joint 9 is threadedly connected to the top of the storage bin 2, wherein the outer surface of the storage bin 2 is surrounded by six faces to form a regular hexagonal structure, and a storage cavity 4 matching the knife head 3 and the second threaded joint 9 is opened inside the storage bin 2, and the storage bin 2 with a hexahedral structure can make it more convenient for the staff to limit the position of the knife bar 1, and grasp the storage bin 2 when twisting the second threaded joint 9;

[0022] One end of the cutter head 3 is fixedly connected to a cutting edge 7, the other end of the cutter head 3 is fixedly connected to a connecting portion 5, one end of the connecting portion 5 is fixedly connected to a first threaded joint 6, and the outer surface of the first threaded joint 6 is threadedly engaged with the inner wall of the second threaded joint 9, wherein the inner wall of the second threaded joint 9 is provided with an internal thread matching the first threaded joint 6, so that the first threaded joint 6 can be screwed into the inner wall of the second threaded joint 9, so that the cutter head 3 can be taken out of the storage cavity 4 and assembled with the second threaded joint 9, and the cutter head 3 can be replaced through the threaded connection between the first threaded joint 6 and the second threaded joint 9.

[0023] One end of the second threaded joint 9 is fixedly connected to a handle 8, which is a spherical structure. After the first threaded joint 6 and the second threaded joint 9 are assembled, the end of the second threaded joint 9 close to the handle 8 is aligned with the storage cavity 4 and then the second threaded joint 9 is screwed to the top of the storage bin 2, so that the entire seal cutting knife can be transformed from the idle state b to the use state a.

[0024] The second threaded joint 9 is symmetrically provided with slots 10 at one end away from the turning handle 8, the two slots 10 are on the same straight line, and the width of the two slots 10 matches the thickness of the blade 7. After use in the use state a, when the cutter head 3 is unscrewed from the second threaded joint 9, the end of the second threaded joint 9 is almost flush with the end of the storage bin 2. At this time, the end of the cutter head 3 close to the blade 7 is aligned with the slot 10, and the blade 7 can be used to clamp the slot 10 to drive the rotation of the second threaded joint 9, thereby taking the second threaded joint 9 out from the top of the storage bin 2, and then the cutter head 3 is put into the storage cavity 4, and the second threaded joint 9 is screwed into the storage bin 2 with the turning handle 8 facing outward, so as to realize the transformation of the entire seal carving knife from the use state a to the idle state b.

[0025] Another turning handle 8 is fixedly connected to one end of the knife bar 1 away from the storage bin 2. Similarly, holding the turning handle 8 can also limit the position of the knife bar 1, thereby facilitating the staff to turn the other turning handle 8 to unscrew the second threaded joint 9 from the storage bin 2.

[0026] When using a hidden portable seal-carving knife with replaceable blade heads, the blade head 3 can be transformed between a use state and an idle state by installing a first threaded joint 6 and a second threaded joint 9. In the idle state, the blade head 3 is hidden in the storage bin 2. The second threaded joint 9 is unscrewed by the turning handle 8. After the blade head 3 is poured out, the first threaded joint 6 and the second threaded joint 9 are assembled. Subsequently, the end of the second threaded joint 9 close to the turning handle 8 is aligned with the storage cavity 4 and then the second threaded joint 9 is screwed onto the top of the storage bin 2. This allows the entire seal-carving knife to be transformed from an idle state b to a use state a. In the use state a, the blade head 3 can be freely assembled at the end of the storage bin 2. At the same time, the second threaded joint 9 can be configured with blade heads 3 of different styles for seal-carving, which is more applicable.

[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
