Description

Wood carving knife handle

Technical Field

The utility model relates to a manual sculpture technical field especially relates to a wood carving tool handle.

Background

The wood carving knife is a main tool for making wood carving prints. The knife shape has three types of u, v and w, namely circular, prismatic and multi-tough, and is matched with various sizes. The handle of the traditional wood carving knife is like a pencil-shaped long strip, and when the knife is used for carving lines, the traditional wood carving knife is roughly like a pencil. However, such a pen-holding operation is very inconvenient to exert force, and is mainly performed by friction force generated by clamping the thumb, the index finger and the middle finger to exert force or hold the handle to prevent the handle from falling off, but after long-time carving, the clamping force of the three fingers is gradually loosened and weak, so that the carving operation is difficult to be smoothly performed, and the working efficiency and the working quality are affected.

Detailed Description

It is first defined that, unless otherwise specified, the handle of the wood carving tool and its related sub-components are a head end (or front end) at the end facing the tool 1 and a tail end (or rear end) at the end away from the tool 1.

As shown in fig. 1 and fig. 2, the handle of the wood carving tool of the present invention has a rod portion 6 for fixing the tool 1 at the head end, and a support portion 7 for supporting the palm, wherein the rod portion 6 and the support portion 7 can be integrally formed, and can also be fixedly connected in other manners. Because the support part 7 for supporting the palm is arranged, when the wood nicking tool provided with the handle is used, the force is exerted without the full-force clamping rod part 6 of the thumb, the index finger and the middle finger, but the palm (particularly the tiger mouth of the palm in the preferred embodiment) is used for propping against the support part 7 for carving when the force is exerted, so that the physical energy of the fingers of a user is saved, occupational diseases are prevented, the force for exerting the force can be greatly improved by pushing the support part 7, the knife feeding is deeper, the removal amount is larger during carving, and the working efficiency is improved.

Further, the holder 7 is preferably integrally formed at the tail end of the rod portion 6 in the present embodiment, so that the handle of the wood carving knife integrally presents an L-shaped structure. The handle of the wood nicking tool with the structure is small and compact in structure and accords with the physiological characteristics of the palm of a human body, so that the rod part 6 is convenient to hold and keep better controllability, and the support part 7 forming the turning part is convenient to support the palm and is more beneficial to exerting strength. And the L-shaped structure can prevent the tool 1 from rotating along the circumferential direction of the rod part 6 after being held because the bent support part 7 exists, thereby preventing the smooth operation of the carving operation from being influenced.

The above description of the position of the L-shaped structure is defined here: consider the presence of a hollow L-letter with only the delineation lines on the paper, the "sides" of the L-letter (i.e., the L-shaped structure) above and below the paper, the "inner edge" being the inner edge relatively close to the L-shaped corner, and the "outer edge" being the outer edge relatively far from the corner.

Further, the shaft portion 6 has a taper with a thin head end and a thick tail end, so that it forms a tapered surface 2 as shown in fig. 1 and 2, and the taper of the tapered surface 2 is preferably 1: 8. By setting the taper, particularly the taper of 1:8, the rod part 6 can be better attached to fingers when being held by a thumb, an index finger and a middle finger, particularly when the thumb and the index finger pinch an object, an included angle can be formed naturally by the two fingers, and the taper of 1:8 is more matched with the angle, so that the thumb and the index finger can clamp the rod part 6 by most of finger bodies, compared with the original condition that a long straight handle can only be pinched by finger tips, the force for clamping the rod part 6 by the finger bodies is larger (particularly the finger bodies close to the root parts of the fingers), the holding posture enables the human body to be less fatigued, and the tool setting can be controlled more freely due to the lifting of the force. In addition, the rod part 6 with the conical surface generates a backward component force after being clamped, and the forward thrust of the palm to the support part 7 is matched, so that an operator can better hold the handle, the slipping and deviation can not be generated, the operability is enhanced, and the accuracy of the carving operation is improved.

Further, a first groove 3 can be arranged at the connection position of the rod part 6 and the support part 7. Particularly, when the first groove (3) is arranged at two sides of the L-shaped structure (as shown in figure 2), the tiger's mouth is propped against the support part 7, and when the thumb and the forefinger clamp the rod part 6, the root parts of the thumb and the forefinger are positioned at the first groove 3 (the first groove 3 is arranged at the position where the thumb and the forefinger are contacted with the penholder when a pen is clamped by the finger root, so that the fingers can better cling to the handle, and after the fingers are clamped in the first groove 3, the whole handle of the wood nicking tool is positioned by the root parts of the fingers which are forced to be larger, and because the finger root and the finger tip are just equivalent to the force path difference between the fulcrum of the lever and the far end, the whole handle is not easy to slip and move after being clamped and clamped by the finger root, can be firmly controlled by an operator, enhances the operability of the wood nicking tool, and can bear the pressure of the tiger's mouth on the support part 7 when force is exerted, reduce soft tissue injury caused by long-term use of compressing local tissues at the tiger's mouth.

In addition, the first groove 3 may be provided on the inner edge of the L-shaped structure (as shown in fig. 1), so that the first groove 3 is connected at least on three sides, or forms a surrounding loop at the end of the rod portion 6. The first groove 3 in the L-shaped structure can enable the middle finger to be fist-held when the handle is held, the fist-held middle finger can be clamped at the first groove 3, and the effect that the thumb and the forefinger are clamped at the first groove 3 is achieved.

Furthermore, the front end of the support part 7 is provided with an inclined surface 4 (as shown in fig. 1) which is inclined towards the tail end of the rod part 6, and the inclined surface can be attached to fingers of a fist when the middle finger or the ring finger is fist-held, so that the handle control operation performance of the handle of the wood carving knife when being held is further enhanced, the overall holding feeling is stronger, and a user can feel more comfortable when carrying the knife.

Furthermore, as shown in fig. 1, the tail end of the support part 7 may have a second groove 5, and the second groove 5 may not only fit the shape of the web of tiger but also allow the web of tiger to generate a clamping and fixing effect on the handle when the web of tiger supports the support part 7 to exert force, thereby preventing the wood nicking tool from generating longitudinal rotation during carving.
