Description

Technical Field

[0001] This utility model relates to the field of book carving knife technology, specifically an adjustable force carving knife device. Background Technology

[0002] Calligraphy engraving is a new art form that integrates various artistic elements. With calligraphy as its core, it incorporates traditional engraving, seal carving, painting, printmaking, and other similar art forms, forming its own unique artistic style. It possesses three main characteristics: two-dimensional composition, three-dimensional composition, and color composition.

[0003] There are two main methods of using a carving knife: "chising" and "carving". The chising method involves holding the knife in the left hand and a mallet (wooden mallet or stick) in the right hand, striking the handle with explosive force to drive the chisel into the wood for carving. However, the force generated by the striking is very difficult for the user to control. If the striking force is too weak, the work cannot be completed, and if the force is too strong, the entire work may even crack. Therefore, an adjustable force carving knife device is proposed to solve the above problems. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides an adjustable-force carving knife device, which has the advantages of adjustable carving force. It solves the problem that the force generated by striking is very troublesome for users to control, and when the striking force is too small, the work cannot be completed, while when the force is too large, the entire work may even crack.

[0006] (II) Technical Solution

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: An adjustable force carving knife device includes a hand-held shell, the hand-held shell is provided with an adjusting sleeve threadedly connected thereto, a thrust spring is provided between the hand-held shell and the adjusting sleeve, the adjusting sleeve is slidably connected to a movable component, and the adjusting sleeve is provided with a positioning component adapted to the movable component.

[0008] The active component is provided with a connecting component, and a clamping sleeve is provided on the outside of the connecting component for threaded connection. The connecting component is also provided with a cutting tool component.

[0009] The beneficial effects of this utility model are:

[0010] 1) This adjustable-force engraving knife device requires downward striking during use, causing the movable component to move towards the handheld housing. During this process, the movable component is held in place by the positioning component, allowing the force at the tail of the handheld housing to be transmitted to the engraving knife component. If the force is too great, the movable component will slide past the positioning component, causing it to retract inward and preventing engraving problems caused by excessive force. When the force needs to be adjusted, simply hold the movable component and rotate the handheld housing. This will cause the adjusting sleeve to rotate inside the handheld housing, and the screw thread will push the adjusting sleeve into the handheld housing. This will compress the thrust spring, increasing the thrust on the positioning component and enhancing its stability. This will prevent the movable component from sliding past the positioning component, thus increasing the engraving force and providing the advantage of adjustable engraving force.

[0011] 2) When the adjustable force engraving knife device needs to replace the knife head, simply rotate the clamping sleeve, which will be driven away from the connecting component by the thread, thereby releasing the limit on the engraving knife component, so that the engraving knife component can be taken out for replacement. Then, rotate the clamping sleeve in the opposite direction to re-limit the new engraving knife component, which has the advantage of replaceable knife head.

[0012] Based on the above technical solution, the present invention can be further improved as follows.

[0013] Furthermore, the movable component includes a sliding sleeve, a return spring, and a push ring. The adjusting sleeve is slidably connected to the sliding sleeve, the sliding sleeve is provided with a return spring, and the sliding sleeve is provided with a push ring.

[0014] Furthermore, the positioning assembly includes a push rod, a hinge seat, a hinge rod, and a positioning block. The adjusting sleeve is movably connected to the push rod, the push rod is provided with a hinge seat, the hinge seat is movably connected to the hinge rod, and the adjusting sleeve is movably connected to a positioning block extending to the outside of the adjusting sleeve and movably connected to the hinge rod. The positioning block is inclined, and the push ring is inclined to match the positioning block.

[0015] The beneficial effect of adopting the above-mentioned further solution is that when the hammer strikes the hand-held shell for engraving, the sliding sleeve moves towards the hand-held shell. During this process, the sliding sleeve is locked by the positioning block through the push ring. In this process, when the force is too large, the push ring can slide past the positioning block, thereby causing the sliding sleeve to retract inward, preventing the engraving problem from being caused by excessive force.

[0016] Furthermore, the connecting assembly includes a connecting seat and a connecting claw, the sliding sleeve is provided with a connecting seat, the connecting seat is provided with a connecting claw, and the connecting seat is threadedly connected to a clamping sleeve adapted to the connecting claw;

[0017] Furthermore, the engraving tool assembly includes a cutting head and a connecting chuck, the connecting jaws are provided with a connecting chuck, and the connecting chuck is provided with a cutting head.

[0018] The advantage of adopting the above-mentioned further solution is that when it is necessary to replace the cutter head, simply rotate the clamping sleeve, thereby driving the clamping sleeve away from the connecting jaws under the push of the thread, so that the connecting jaws open, thereby releasing the limit on the connecting chuck, and the cutter head can be taken out for replacement.

[0019] Furthermore, the handheld shell is equipped with a hammer head, and a reinforcing ring is fitted around the outside of the hammer head.

[0020] The advantage of adopting the above-mentioned further solution is that it can be engraved by striking the hammer head, preventing damage to the handheld casing from being struck.

[0021] Furthermore, a strap is provided on the outside of the handheld shell.

[0022] The beneficial effect of adopting the above-mentioned further solutions is that it makes the handheld case feel better to hold. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1, by Figure 1-6 The present invention provides an adjustable force carving knife device, comprising a hand-held shell 1, an adjusting sleeve 2 threadedly connected to the hand-held shell 1, a thrust spring 3 between the hand-held shell 1 and the adjusting sleeve 2, a movable component 4 slidably connected to the adjusting sleeve 2, and a positioning component 5 adapted to the movable component 4.

[0032] The active component 4 includes a sliding sleeve 41, a return spring 42, and a push ring 43. The adjusting sleeve 2 is slidably connected to the sliding sleeve 41. The sliding sleeve 41 is provided with a return spring 42 and a push ring 43.

[0033] The positioning assembly 5 includes a push rod 51, a hinge seat 52, a hinge rod 53, and a positioning block 54. The adjusting sleeve 2 is movably connected to the push rod 51. The push rod 51 is provided with a hinge seat 52. The hinge seat 52 is movably connected to the hinge rod 53. The adjusting sleeve 2 is movably connected to the positioning block 54, which extends to the outside of the adjusting sleeve 2 and is movably connected to the hinge rod 53. The positioning block 54 is set with an inclined surface. The push ring 43 is set with an inclined surface that is adapted to the positioning block 54.

[0034] When the hammer strikes the hand-held shell 1 for engraving, the sliding sleeve 41 moves toward the hand-held shell 1. During this process, the sliding sleeve 41 is held in place by the positioning component 5 through the push ring 43. If the force is too great, the push ring 43 can slide past the positioning block 54, thereby causing the sliding sleeve 41 to retract inward, preventing the engraving from being damaged by excessive force.

[0035] In Embodiment 2, based on Embodiment 1, the movable component 4 is provided with a connecting component 6, and a clamping sleeve 7 is provided on the outside of the connecting component 6 for threaded connection. The connecting component 6 is also provided with a cutting tool component 8.

[0036] The connecting assembly 6 includes a connecting seat 61 and a connecting claw 62. The sliding sleeve 41 is provided with a connecting seat 61, the connecting seat 61 is provided with a connecting claw 62, and the connecting seat 61 is threadedly connected to a clamping sleeve 7 that is adapted to the connecting claw 62.

[0037] The engraving tool assembly 8 includes a cutting head 81 and a connecting chuck 82. The connecting jaw 62 is provided with the connecting chuck 82, and the connecting chuck 82 is provided with the cutting head 81.

[0038] When the cutter head needs to be replaced, simply rotate the clamping sleeve 7, which will be pushed away from the connecting jaw 62 by the thread, thereby opening the connecting jaw 62 and releasing the limit on the connecting chuck 82, so that the cutter head 81 can be taken out for replacement.

[0039] The handheld shell 1 is equipped with a hammer head 9, and a reinforcing ring is fitted on the outside of the hammer head 9;

[0040] Engraving can be done by striking the hammer head 9 to prevent damage to the handheld shell 1 from being struck.

[0041] A strap 10 is provided on the outside of the handheld case 1;

[0042] This makes the grip of the hand-held case 1 feel better.

[0043] Working principle:

[0044] Implementation steps for the first innovation point:

[0045] Step 1: During the use of the carving knife, it is necessary to strike downwards, so that the moving component 4 moves towards the hand-held shell 1. During this process, the sliding sleeve 41 is locked by the positioning block 54 through the push ring 43, so that the force located at the tail of the hand-held shell 1 can be transmitted to the cutting head 81.

[0046] Step 2: During this process, if the force is too great, the push ring 43 can slide past the positioning block 54, thereby causing the sliding sleeve 41 to retract inward, thus causing the cutter head 81 to lose force and preventing the engraving problem from being caused by too much force.

[0047] Step 3: When the force needs to be adjusted, simply hold the movable component 4 and rotate the handheld shell 1. This will cause the adjusting sleeve 2 to rotate inside the handheld shell 1. Under the push of the thread, the adjusting sleeve 2 will move into the handheld shell 1, causing the thrust spring 3 to compress and deform, thereby increasing the thrust on the push rod 51 and enhancing the stability of the positioning block 54. This will make it difficult for the push ring 43 to slip past the positioning block 54, thus achieving the effect of increasing the engraving force.

[0048] Implementation steps for the second innovation point:

[0049] Step 1: When it is necessary to replace the cutter head, simply rotate the clamping sleeve 7, thereby driving the clamping sleeve 7 away from the connecting jaw 62 under the push of the thread;

[0050] Step 2: This causes the connecting claw 62 to open, thereby releasing the restriction on the connecting chuck 82, allowing the cutter head 81 to be removed;

[0051] Step 3: Finally, reposition the new cutter's connecting chuck 82 inside the connecting jaws 62, thereby rotating the clamping sleeve 7 in the opposite direction. This causes the clamping sleeve 7 to re-clamp the connecting jaws 62, thus allowing the connecting jaws 62 to re-limit the connecting chuck 82 and fix the new cutter head 81.
