The protection ridges are arranged along the arm direction, which can smoothly fit the shape of the arm and does not affect the movement of the user's arm. The groove extending along the arm direction can make the protection ridges on both sides approach each other or move away from each other relatively. When the arm makes a move, especially when the arm rotates, it can also keep the protection part and the arm part in close cooperation. While ensuring the protection effect of the arm part, it can also reduce the restraint effect of the arm guard and the protection part on the movement of the arm.
[0007] A metal reinforcing rib is embedded in the protection ridge, which can further enhance the effect of preventing cutting and slashing at the position of the protection ridge.
[0008] The vertical cross-section of the protective rib is trapezoidal, which is convenient for absorbing impact force, dispersing pressure and improving the effectiveness of protection.
[0009] The vertical cross-section of the metal reinforcing rib is circular, oval or flat rectangular, which can improve the support strength of the structure and has better anti-cutting and anti-slashing effects.
[0010] The protective rib extends longitudinally along the arm direction, and the groove extends longitudinally along the arm direction. The extension of the rib and the groove along the arm direction can further improve the matching degree with the arm.
[0011] The protective part is located on the outer surface of the arm guard body between the elbow and the wrist, which can avoid affecting the mobility of the joint part and improve the comfort and followability during use.
[0012] The overall shape of the protective part is a shield shape with a larger upper part and a smaller lower part, which has a sufficient protection area and a high degree of fit with the arm movement.
[0013] A through hole for the thumb to pass through is provided on the wrist side of the arm guard body, which is convenient for the thumb to pass through, fixes one end of the arm guard body at the wrist, ensures that the protective part does not move during arm movement, and effectively ensures the protection effect on the outer side of the arm.
[0014] The protective rib extends in an arc along the arm direction, and the groove extends in an arc along the arm direction. The arc-shaped extended protective rib and groove can prevent the tip of the knife from piercing in, improve the protection performance of the groove part, and in addition, they can move relatively far away or close to each other, and can also follow the movement of the arm without producing a lag effect.
[0015] The advantages of the present utility model are: strong followability, comfortable to wear, convenient for folding and storing, and good protection effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Embodiment
[0022] Refer to Figures 1-4 , a cut- and slash- resistant arm guard, comprising an arm guard body 1 made of cut- and slash- resistant fabric. A longitudinally extending protective part 2 is provided on the outer surface of the arm of the arm guard body 1. A plurality of elastic material protective ridges 3 are provided on the upper surface of the protective part 2 along the arm direction. A groove 4 extending along the arm direction is formed between two adjacent protective ridges 3.
[0023] The arm guard body 1 itself is made of cut- and slash- resistant fabric, such as woven or circularly woven with aramid, high- molecular polyethylene and other yarns. Because the fabric material itself has certain cut- and slash- resistant performance, it can directly defend against the cut and slash of kitchen knives and daggers, and has the effect of protecting the whole arm. And because of the fabric nature of the arm guard body 1, it can be folded by itself, which is convenient for storage. The protective part 2 is arranged on the outer surface of the arm of the arm guard body 1, which can significantly enhance the cut- and slash- resistant defensive effect of the outer part of the arm, and also has a certain active attack performance. Moreover, the protective part 2 is longitudinally arranged on the outer side of the arm, which does not affect the overall folding of the arm guard body 1. The protective ridges 3 extend along the arm direction, which can smoothly fit the shape of the arm and does not affect the movement of the user's arm. The groove 4 extending along the arm direction can make the two sides of the protective ridges approach or move away from each other. When the arm moves, especially when the arm rotates, it can also keep the protective part and the arm part in close cooperation. While ensuring the defensive effect of the arm part, it can also reduce the restraint effect of the arm guard and the protective part on the arm movement. The protective ridges 3 can be made of rubber, silica gel or other materials with buffer elasticity, which can play a buffer effect under impact and protect the arm.
[0024] In this embodiment, the vertical section of the protective ridge 3 is trapezoidal. On the one hand, it can effectively disperse the pressure and improve the protective effect. In addition, it is convenient to embed a longitudinally extending metal reinforcing rib 5 to provide a better protective effect. The vertical section of the metal reinforcing rib 5 is circular, oval or flat rectangular, and is made of relatively lightweight aluminum alloy or stainless steel. To ensure a better protective effect, the metal reinforcing rib 5 embedded in the protective ridge 3 can be a whole root slightly shorter than the protective ridge 3, or can be composed of multiple segments spliced together.
[0025] In this embodiment, the protective ridges 3 and the grooves 4 respectively extend longitudinally along the arm direction, which can further improve the cooperation degree with the arm. The protective ridges 3 and the grooves 4 can also be arranged to extend in an arc along the arm direction. When the arm rotates, it can also follow the arm, and there will be no lag consequences. The arc- extending protective ridges 3 and grooves 4 can prevent the tip of the knife from piercing in and improve the protective performance of the groove 4 part.
[0026] The protection part 2 is located on the outer surface of the arm guard main body 1 between the elbow and the wrist. After wearing, the arm guard main body 1 can not affect the mobility of the arm joint parts, improving the comfort and followability during use.
[0027] The overall shape of the protection part 2 is a shield shape with a larger upper part and a smaller lower part. The protection area is sufficient and the fit with the arm movement is high.
[0028] A through hole 6 for the thumb to pass through is provided on the wrist side of the arm guard main body 1. It is convenient for the thumb to pass through, fixing one end of the arm guard main body 1 at the wrist, ensuring that the protection part does not move during arm movement, and effectively ensuring the protection effect on the outer side of the arm.
