Description

Technical Field

[0001] This utility model belongs to the field of cutting tool and equipment technology, and specifically relates to a utility knife that is easy to cut. Background Technology

[0002] A utility knife, also known as a carving knife or wallpaper knife, is a type of knife used for art and handicrafts. It's primarily used for cutting soft materials and typically consists of a plastic handle and a blade, with a pull-out design. A few have metal handles. The blade is usually beveled; when dull, it can be broken along the lines drawn on the blade to create a new edge, making it easier to use. Current utility knives require a finger grip for cutting, using the fingers as support to control the cutting force and speed. For example, when cutting straight lines, the blade needs to be held close to a ruler, sliding along the edge of the ruler. This requires one hand to hold the ruler down while the other hand holds the utility knife, making it difficult to control the force and direction. Furthermore, the blade is too close to the hand holding the ruler, increasing the risk of cuts and reducing safety. Utility Model Content

[0003] The purpose of this utility model is to solve the problems existing in the background technology mentioned above and provide a utility knife that is easy to cut. By using a guide mechanism set under the blade shell, the finger is replaced from contacting the object to be cut. The rolling guide mechanism can move freely when pressed, thereby driving the blade to move for cutting. When using it, the hand does not come into contact with the object being cut, making it easier to control the force and direction of the utility knife and improving safety performance.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a utility knife that is easy to cut, comprising a knife housing, a rear plug, a push button, a blade, and a guide mechanism. The blade is slidably connected inside the knife housing, and its tail is fastened to the rear plug. The push button is installed inside the knife housing, with its upper end slidably connected to the knife housing and its lower end connected to the blade through a fixed post. The guide mechanism includes a snap-fit ​​outer shell and a rolling element. The rolling element is rotatably connected to the outer shell, wherein the lower front end of the outer shell is provided with an inclined corner, and the rolling element extends out of the corner.

[0005] Furthermore, a slot is provided at the lower end of the head of the tool housing, and the slot is fastened to the outer shell.

[0006] Furthermore, the rolling element includes a rolling shaft and a roller. A fixing seat for inserting the rolling shaft is provided in the middle of the inner side of the housing. A through hole is provided at the lower end of the housing. The rolling shaft is installed in the fixing seat perpendicular to the housing. The roller passes through the rolling shaft and is rotatably connected to the housing. The lower end of the roller protrudes through the through hole at the bottom of the housing.

[0007] Furthermore, the rolling element is a ball bearing, and the outer shell is provided with a spherical groove for installing the ball bearing. The lower end of the outer shell is also provided with a circular hole communicating with the spherical groove, and the roller is fixed at the bottom of the outer shell at the rear end extending outward from the circular hole.

[0008] Furthermore, arc-shaped baffles are provided on both sides of the outer shell.

[0009] Furthermore, the outer shell is integrally formed with the tool housing.

[0010] The beneficial effects of this utility model are: 1) This utility model uses a guide mechanism to engage with the blade housing, and uses a rolling element to replace the fingers to provide support and rolling movement, which reduces the friction between the fingers and the workpiece. This not only makes it easier to move and saves effort, but also allows for more precise control of the cutting size and moving distance. The outer shell and baffle can be used as reference lines during movement, so that the movement path is laid out through the outer shell rather than the blade itself, which improves safety performance and makes the operation simple and convenient.

[0015] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0016] Example: As shown in the figure, the utility knife of this invention, which is easy to cut, includes a knife housing 1, a rear plug 2, a push button 3, a blade 4, and a guide mechanism 5. The blade 4 is slidably connected inside the knife housing 1, and its tail is fastened to the rear plug 2. The push button 3 is installed inside the knife housing 1, with its upper end slidably connected to the knife housing 1 and its lower end connected to the blade 4 through a fixing post. The guide mechanism 5 includes a snap-fit ​​outer shell 6 and a rolling element 7. The rolling element 7 is rotatably connected to the outer shell 6. The lower front end of the outer shell 6 is provided with an inclined corner, and the rolling element 7 extends out of the corner.

[0017] The lower end of the head of the knife housing 1 is provided with a slot 8, which is fastened to the outer shell 6. When in use, the guide mechanism 5 can be freely disassembled through the slot 8 to switch the guide function of the utility knife, and it is also convenient for maintenance, carrying and daily cleaning; or the outer shell 6 and the knife housing 1 can be integrally formed, which can improve the structural strength of the guide mechanism 5 and enhance its service life.

[0018] The rolling element 7 includes a rolling shaft 9 and a rolling shaft 10. A fixing seat 11 for inserting the rolling shaft 9 is provided in the middle of the inner side of the housing 6. A through hole 12 is provided at the lower end of the housing 6. The rolling shaft 9 is installed in the fixing seat 11 perpendicular to the housing 6. The rolling shaft 10 passes through the rolling shaft 9 and is rotatably connected to the housing 6. The lower end of the rolling shaft 10 protrudes through the through hole 12 at the bottom of the housing 6. When in use, the tilted utility knife contacts the object with the blade tip, using the rolling shaft 10 as the support point and the handle as the other end. The rolling shaft 10 provides support and rolling, while the handle provides downward pressure at the blade tip and driving force to move the blade tip. During the process, the rolling shaft 10 moves by rolling friction, which can save the amount of cutting force compared to finger support.

[0019] The rolling element 7 uses ball bearings 13. The outer shell 6 has a spherical groove 14 for installing the ball bearings 13. The lower end of the outer shell 6 also has a circular hole communicating with the spherical groove 14. The roller is fixed to the bottom of the outer shell 6, which extends outward from the circular hole. Similarly, the structure of roller and spherical groove 14 not only facilitates movement and saves effort, but also allows the roller to rotate without dead angles on the plane, thereby driving the blade tip to move at any angle and cut any shape. With the roller as an auxiliary support point, the downward pressure can be transmitted in cooperation. When moving downward, the support point is pressed down to make it fit with the object, and then the force is transmitted to the blade tip in the form of a lever for cutting, which can precisely control the cutting force.

[0020] Arc-shaped baffles 15 are also provided on both sides of the outer shell 6. In use, the arc-shaped baffles 15 are located at the bottom of the outer shell 6, that is, at the junction of the rolling element 7 and the outer shell 6. The arc-shaped baffles 15 are conveniently limited by a straight reference object, so that the guide mechanism 5 can only move along the direction of the outer shell 6 to cut the item, without directly contacting the blade 4, thus improving safety during cutting.

[0021] This invention uses a guide mechanism to engage with the blade housing, and a rolling element to replace the fingers for support and rolling movement, reducing friction between the fingers and the workpiece. This allows for more precise control of the cutting size and movement distance. The outer shell and baffle can serve as reference lines during movement, ensuring the movement path is laid out through the outer shell rather than the blade itself, thus improving safety. The design is simple and convenient to use.

[0022] The above description is only used to illustrate the technical solution of this utility model and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
