Description

utility knife

本实用新型涉及一种美工用具，尤指一种美工刀。The utility model relates to an art tool, in particular to an art knife.

现有技术的美工刀1如图1所示，其具有一供人手握持施力的握把101，于握把101的前端部位设有一呈棘齿状的刀片102，其以轴枢方式设置，以人手抓持该握把101向前或向后推动施力，即可以使刀片102旋转且以其棘齿状部位对纸张进行切割，用来切割纸张的动作非常方便好用，胜过于使用剪刀；但是，一般在操作使用该美工刀1时，为求纸张切边的笔直整齐，必须额外再借助类似于直尺(图未示出)等工具，作为美工刀1操作施力时的靠边，然而因为一般的直尺的厚度较小而概呈长条薄片状，常常容易因为握持美工刀1的右手施力较大，而不知不觉中造成以左手扶持的直尺会受美工刀的推挤而移位，致使切割处的切边歪斜或扭曲而不理想，或者因为一般的直尺以塑胶或压克力材质制成，更常在充当切割的靠边时受到美工刀的划切毁损，影响其本身的直度而无法再作为划线的依据了，以上的缺弊实已困扰消费者许久，常为消费者所垢病，亦为制造者近年来所急欲努力改善的目标！The utility knife 1 of the prior art is shown in Fig. 1, and it has a handle 101 for the human hand to hold and apply force, and a ratchet-shaped blade 102 is arranged at the front end of the handle 101, which is arranged in a pivotal manner. , the handle 101 is grasped by human hands and pushed forward or backward to apply force, so that the blade 102 can be rotated and the paper can be cut with its ratchet-like part. The action of cutting paper is very convenient and easy to use, which is better than using Scissors; however, generally when the utility knife 1 is used in operation, in order to keep the trimmed edge of the paper straight and tidy, an additional tool such as a ruler (not shown) must be used as a backing when the utility knife 1 is operating and exerting force However, because the thickness of the general ruler is small and it is generally in the shape of a long thin sheet, it is often easy to cause the ruler held by the left hand to be affected by the utility knife unknowingly because the right hand holding the utility knife 1 exerts a large force. Pushing and shifting, causing the cutting edge to be skewed or twisted, which is not ideal, or because the general ruler is made of plastic or acrylic material, it is more often cut by a utility knife when it is used as a cutting edge Damage, which affects its own straightness and can no longer be used as a basis for marking. The above shortcomings have troubled consumers for a long time. They are often plagued by consumers and are also the goals that manufacturers are eager to improve in recent years. !
