New description: [New technical field] This creation is a modified structure of plastic wrap cutter, which is set at the middle of the sawtooth row set on the end face of the cutter fixed on the wrap box. The long ore tooth segment is provided with a left and right horizontal mineral tooth segment on both sides of the silver plated tooth row to provide a technical field in which the plastic wrap is easily torn and the hand is cut. [Prior Art] The general wrap film packaging box is provided with a cutting knife at the end of the lid of the packaging box, and the end surface of the δ Xuan cutting knife is provided with a mineral tooth row to facilitate the cutting when the plastic wrap is taken out. The recording tape on the knife smashes the plastic wrap to facilitate the neat tearing of the wrap film. [New content] First, the problem to be solved: 1. The conventional cling film cutting knife, because it is set in a curved shape, often when the middle part of the cling film is punctured, the cling film is pricked to the sides one by one, so that the fresh-keeping The film is widened by the pushing of the teeth. The width of the two ends of the wrap film is beyond the width of the cutting blade, so that the wrap film is not easily torn by nature, and it is inevitable that the user can assist the tear by hand. A careless 'will make it easy for the palm to be cut by a cutting knife. 2. The sawtooth row on the conventional cling film cutter has the same size as the tooth peak and the valley. The width of the middle part of the wrap film is punctured for the first time. Because the serration is small, the wrap film is not easily broken. 'The user must pull the cling film and the crisper in the opposite direction to tear the cling film, but the wrap will be quite irregular. 3 M404841 even caused some traces to be broken, so that the user Inconvenience in use. Second, the means of solution; the creation system is provided on the inside of the cover of the wrap film packaging box, a cutting blade, the end face of the cutting blade is -_ ' and the county end of the curved end face, and in the row of the ore There are several bribes in the middle section of the middle section, and there are left and right horizontal sections at the two ends of the squad: the aforementioned butterfly knife, the towel of the silk nunnu on the plastic wrap box, the _ _ _ _ _ _ _ _ _ _摊 彳 彳|| The 嵩 予以 予以 予以 并 并 并 并 并 魏 魏 魏 魏 魏 魏 魏 魏 魏 魏 魏 魏 魏 魏 魏 魏 魏 魏 魏 魏 魏 魏 魏 魏 魏 魏 魏 魏 魏 魏 魏 魏 魏 魏 魏 魏 魏 魏 魏 魏The cling film is easy to be difficult to avoid, and it is not possible to be torn after the puncture, and attempts to tear the hand by hand, and prevent the palm from being accidentally cut by the cutting knife. [Embodiment] Referring to the first, second, and fifth figures, a cutting blade 1 is disposed in the end of the cover 21 of the wrap film packaging box 2, and the end face of the cutting blade is an arc w, and The curved W end surface is provided with a sawtooth row 1 丨 ' and a plurality of long sawtooth segments 12 ′ are provided at the middle portion of the saw tooth rib 使 so that the serrations of the longer dent portion 12 are longer than the saw teeth of the sawtooth row π; The end positions of the mineral tooth row 11 on both sides of the plurality of long tooth segments 12 of the cutting blade 1 may be respectively provided with a left and right horizontal sawtooth segments W1 and W2; please cooperate with the third, fourth, sixth and seventh figures, the foregoing The cutting blade 1 , wherein the longer recording segment 12 preferentially pierces the middle portion of the wrap film 3 drawn from the wrap film packaging box 2, and then punctures the zigzag row 11 to the sides, and the jagged teeth The left and right horizontal serrations W1 and W2 on both sides of the row 11 will have a retaining 臈3 stop to prevent the plastic wrap 3 which is broken by the punctured 4 M404841, and the two sides are slid and widened by successively squeezing and widening, so that The cling film 3 is easily torn 'and avoids tearing after being punctured and attempts to tear the hand by hand', preventing the palm from being accidentally Shu cutter who cuts. Please refer to the fourth 'six and seven figures, the cutting blade, the longer serrated section 12 provided in the section, can pierce the cling film 3, so that the longer serrated section 完全2 completely completes the section Bao Lai 3 deduction, money _ application of its two _ _ 丨丨 丨丨 丨丨 丨丨 丨丨 丨丨 丨丨 丨丨 丨丨 丨丨 丨丨 丨丨 丨丨 丨丨 丨丨 丨丨 丨丨 丨丨 丨丨 丨丨 丨丨 丨丨 丨丨 丨丨Please refer to the second, sixth and seventh riding instructions.
