Abstract
Description
Technical Field
[0001] This utility model relates to a cutting tool, specifically to a pinch groove type anti-slip knife handle. Background Technology
[0002] A scalpel typically consists of a blade and a handle, with the blade being detachable and replaceable relative to the handle. During use, the hand holding the handle can easily become contaminated with liquids such as medication, blood, tissue fluid, or sweat, posing a safety hazard as the hand can easily slip relative to the handle.
[0003] Existing technology, such as the Chinese utility model patent with publication number "CN211704769U" entitled "surgical scalpel", discloses the following scheme: "A surgical scalpel includes a handle and a blade body. The blade body has a mounting hole on its right side. The handle is movably connected to the blade body. The handle surface has anti-slip texture on its left side and scale texture on its right side. A connecting rope is fixedly connected to the top right side of the handle. A finger ring is fixedly connected to the top of the connecting rope. The blade body is made of titanium alloy and its model number is 10#. The handle is made of titanium alloy and its model number is scale number 3. The anti-slip texture is trapezoidal in shape."
[0004] The above solution, through the combined use of connecting ropes and rings, prevents medical personnel from dropping or slipping the scalpel during clinical surgery.
[0005] However, the connecting cord and ring can easily affect hand movements during actual use and make the scalpel difficult to clean; moreover, without the connecting cord and ring, the anti-slip effect of the anti-slip texture on the outside of the handle is relatively limited.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.
[0027] refer to Figures 1 to 4 A pinch groove type anti-slip knife handle includes a blade 1 and a handle 2. The blade 1 is detachably connected to one end of the handle 2. The blade 1 is used for cutting or slicing, and the blade 1 can be replaced with the handle 2. The handle 2 includes a handle body 21 for hand gripping.
[0028] The handle 21 is provided with a first pinch groove 22, a second pinch groove 23, a support protrusion 26, an arc-shaped protrusion 27, and an anti-slip texture 28; the first pinch groove 22, the second pinch groove 23, the support protrusion 26, the arc-shaped protrusion 27, and the anti-slip texture 28 are all used to provide an anti-slip effect.
[0029] The first pinch groove 22 and the second pinch groove 23 are located on both sides of the handle 21 in the thickness direction, and both the first pinch groove 22 and the second pinch groove 23 are located near the blade 1; both the first pinch groove 22 and the second pinch groove 23 are used for pinching with the fingers.
[0030] Both the first pinch groove 22 and the second pinch groove 23 are grooves; they are concave relative to the outer surface of the handle 21, thereby increasing the coefficient of friction.
[0031] The first pinch groove 22 extends along the length of the handle 21, and the second pinch groove 23 extends along the width of the handle 21; this is to accommodate the habit of most people holding the handle 2 with their right hand.
[0032] The support protrusion 26 is located on both sides of the second pinch groove 23; the support protrusion 26 can press against the finger when the handle 2 slips, to prevent further slippage.
[0033] The arc-shaped protrusion 27 is arc-shaped and is set along the edge of the first pinch groove 22; the arc-shaped protrusion 27 protrudes from the side of the handle 21 to fit the edge of the finger, so that the finger rests on the arc-shaped protrusion 27, which is conducive to fully pinching the handle 21 and reducing the chance of slipping.
[0034] The anti-slip texture 28 is located on both sides of the handle 21 in the thickness direction. The anti-slip texture 28 can play an anti-slip role when gripping the handle 21.
[0035] The first pinch groove 22 is oval-shaped, which is suitable for the horizontal pinching posture of the thumb. The second pinch groove 23 is U-shaped, which is suitable for the vertical pinching posture of the index finger. The second pinch groove 23 is connected to the top of the handle 21 to avoid discomfort to the hand.
[0036] The first pinch groove 22 is provided with a first rib 24, and the second pinch groove 23 is provided with a second rib 25. Both the first rib 24 and the second rib 25 are used to enhance the anti-slip properties.
[0037] The height of the first rib 24 is less than the depth of the first pinch groove 22, and the uneven surface is conducive to improving the coefficient of friction; the height of the second rib 25 is less than the depth of the second pinch groove 23, and the uneven surface is conducive to improving the coefficient of friction.
[0038] The first rib 24 and the second rib 25 both extend along the thickness direction of the handle body 21; the first rib 24 and the second rib 25 are integrally formed with the handle body 21, making them durable and preventing them from falling off.
[0039] The support protrusions 26 are located on both sides of the second pinch groove 23 near the top of the handle 21; the support protrusions 26 are cylindrical and can block the fingers.
[0040] The end of the support protrusion 26 is provided with a rounded head structure to avoid injury to the fingers; the support protrusion 26 is integrally formed with the handle body 21, making it durable and preventing it from falling off.
[0041] The arc-shaped protrusion 27 is located at the end of the first pinch groove 22 away from the blade 1. The arc-shaped protrusion 27 is consistent with the curvature of the edge of the first pinch groove 22, which is suitable for the thumb to press the inner contour of the first pinch groove 22. The arc-shaped protrusion 27 is integrally formed with the handle body 21, which is durable and will not fall off.
[0042] The anti-slip texture 28 is a raised or recessed texture, and the direction of the anti-slip texture 28 is parallel to the width direction of the handle 21, resulting in a high coefficient of friction.
[0043] The working principle of this utility model is as follows:
[0044] When it is necessary to use the knife, hold the handle 2. Specifically, taking the right hand to hold the handle 2 as an example, the right thumb presses in the first pinch groove 22; the right index finger presses in the second pinch groove 23.
[0045] That is, the thumb and index finger of the right hand pinch the first pinch groove 22 and the second pinch groove 23 from both sides of the handle 21 of the knife handle 2.
[0046] Since the first rib 24 and the second rib 25 are respectively provided in the first pinch groove 22 and the second pinch groove 23, the thumb and index finger can pinch the multiple first ribs 24 and the second ribs 25 to achieve anti-slip.
[0047] When the thumb presses the first pinch groove 22, the thumb will also press on the inside of the arc-shaped protrusion 27 and come into contact with the arc-shaped protrusion 27, which can prevent the handle 21 from slipping relative to the hand along the length direction.
[0048] When the index finger presses into the second pinch groove 23, if the handle 21 slips along the length of the hand, it will touch one of the support protrusions 26 on both sides of the second pinch groove 23, thereby blocking and preventing further slippage.
[0049] The base of the thumb, along with the middle, ring, and little fingers, press against the anti-slip texture 28 on both sides of the handle 21.
[0050] The above anti-slip structures work together to achieve a strong anti-slip effect on the handle 21.
[0051] The above embodiments are used to further illustrate the present invention, but do not limit the present invention to these specific embodiments. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be understood as being within the protection scope of the present invention.
