Description

Technical Field

[0001] The utility model belongs to the technical field of school supplies, in particular to an art knife with a scale. Background Art

[0002] Utility knife, also known as carving knife or wallpaper knife, is a kind of knife used for art and handicrafts. It is mainly used to cut soft things. Most of them are made of plastic handle and blade, and are pull-out structures. There are also a few with metal handles. The blades are mostly beveled. When blunt, they can be broken along the line of the blade, and a new blade will appear, which is convenient for use. Utility knives come in many sizes. When a utility knife is used normally, only the tip of the knife is usually used. Cutting, carving, and dotting are the main functions.

[0003] The tape measure is a common measuring tool in daily life. The one you often see is the steel tape measure, which is commonly used in construction and decoration, and is also one of the essential tools for the family. The tape measure can be rolled up because there is a spring inside the tape measure. When it is pulled out to measure the length, it actually lengthens the length of the ruler and the spring. Once the measurement is completed, the spring inside the tape measure will automatically shrink, and the ruler will also shrink under the action of the spring force, so the tape measure will roll up, which is very convenient to use.

[0004] Generally speaking, the distance is measured and then cut with a utility knife. In this case, you need to switch between two tools, and it is very easy to scratch your fingers. Summary of the invention

[0005] In order to solve the above technical problems, a technical solution adopted by the utility model is:

[0006] A utility knife with a scale, comprising a housing portion, and a cutting portion and a measuring portion installed in the housing portion;

[0007] The housing portion includes a first housing, a second housing, and a partition disposed in the first housing and the second housing;

[0008] The cutting part comprises a driving member rotatably connected to the second housing and a blade for cutting, wherein the blade is fixed to the rotating member, and the rotating member drives the blade to rotate on the first housing, and the driving member is further provided with a first elastic element for resetting the driving member;

[0009] The measuring part includes a first roller and a gear set rotating on the second shell, the first roller is meshed with the gear set, the output end of the gear set is meshed with the first winding wheel, the first winding wheel is provided with a rebound member for driving the first winding wheel, and the second shell is also provided with a second winding wheel, the tape measure passes around the guide wheel and is wound around the first winding wheel and the second winding wheel, and the second winding wheel is also meshed with the second roller.

[0010] Furthermore, the cutting part also includes a second elastic element, one end of the second elastic element is connected to the driving member, and the other end is connected to the rotating member. When the driving member is pressed, the driving member can press the blade to cut, and when the driving member is released, the second elastic element resets the blade.

[0011] Furthermore, the resilient member includes a resilient block rotating in the second shell and a third elastic element arranged in the resilient block, one end of the third elastic element is fixedly connected to the second shell, and the other end is fixedly connected to the resilient block, and the resilient block engages with the first winding wheel.

[0012] Furthermore, the first shell is provided with a knife hole for the blade to pass through.

[0013] Furthermore, the second housing is also provided with a first through hole and a second through hole for the tape measure to pass through.

[0014] Beneficial effects of the utility model:

[0015] The utility model integrates the measuring tape and the blade together, and the length can be quickly measured by sliding. The blade can be ejected by pressing the driving part to form a cutting and cutting function. The switching is convenient and the safety performance is high. If the driving part is pressed and the first rotating part is rolled at the same time, the cutting length can be observed, which is very convenient. BRIEF DESCRIPTION OF THE DRAWINGS
