Description

Technical Field

[0001] This utility model relates to the field of art and craft technology, specifically to an art knife with a fixed function. Background Technology

[0002] A utility knife, also known as a carving knife or wallpaper knife, is typically used only with the tip. Its main functions are cutting, carving, and marking. However, the blade is quite brittle, so it cannot be extended too far. Furthermore, the hardness and durability of the blade vary depending on the material used.

[0003] Patent publication number CN211250111U discloses a utility knife, including a blade, a tail cap, and a cavity formed by the blade and the tail cap. The blade includes a shell and an iron core, and the blade is disposed in the iron core. The blade can move under the action of an external force from a push button disposed on the iron core. It also includes a safety lock switch, which includes a bottom and a side. The bottom is disposed at the lower part of the push button and can move back and forth with the push button.

[0004] To address the lack of a safety locking function, existing technology employs a safety lock switch and a safety control device. When the utility knife is needed, the safety lock switch is pushed out of the slot, and the protruding structure engages with the first groove, allowing the blade to slide freely under external force. When the blade is not in use, the protruding structure engages with the second groove, and the side of the safety lock switch engages with the slot, locking the push button and preventing the blade from moving forward or backward. However, this method still suffers from issues such as blade movement due to gaps between parts during use, excessive noise when pushing the blade, and poor adaptability. Utility Model Content

[0005] The purpose of this utility model is to provide a utility knife with a fixed function to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A utility knife with a fixing function includes a blade, the surface of which is provided with a fixing mechanism and an adjustment mechanism.

[0008] The fixing mechanism includes a housing, which is movably mounted on the surface of the adjusting mechanism. A first button is movably mounted on one side of the housing, one end of which extends into the interior of the housing. Movable plates are fixedly mounted on both ends of the first button, and guide posts are movably mounted on the surface of the movable plates.

[0009] A further improvement of this utility model is that: two sets of guide posts are provided, the guide posts are symmetrically distributed on the surface of the movable plate, a limit block is fixedly installed at the top of the guide post, and a first spring is sleeved on the surface of the guide post, with the two ends of the first spring being fixedly connected to the outer shell and the movable plate, respectively.

[0010] A further improvement of this utility model is that: a pressure plate is fixedly installed at one end of the movable plate, and a first anti-slip plate is fixedly installed on the surface of the pressure plate, and the first anti-slip plate is movably installed on the left side of the blade.

[0011] A further improvement of the present invention is that the fixing mechanism further includes a fixing block, which is fixedly installed inside the blade. A second anti-slip plate is fixedly installed on the surface of the fixing block. The second anti-slip plate is movably installed on the right side of the blade and is parallel to the first anti-slip plate.

[0012] A further improvement of this utility model is that: the adjustment mechanism includes a slide rail, the slide rail is disposed at the top of the housing, a slider is movably mounted on the surface of the slide rail, a fixed seat is fixedly mounted at the bottom end of the slider, a movable groove is provided on the surface of the fixed seat, a slot strip is fixedly mounted inside the housing, the slot strip is symmetrically distributed on both sides of the fixed seat, a second button is movably mounted on the surface of the slider, a base plate is fixedly mounted at the bottom end of the second button, and the base plate is movably mounted inside the slider.

[0013] A further improvement of the present invention is that: a second spring is fixedly installed at the upper end of the base plate, and multiple sets of the second spring are provided. The second springs are evenly distributed at the upper end of the base plate. A locking post is fixedly installed at the lower end of the base plate. The locking post is movably installed on the surface of the movable groove and passes through the fixed seat. The locking post is adapted to the locking groove strip.

[0014] A further improvement of this utility model is that: a vertical plate is fixedly installed at the bottom of the fixed base, a protrusion is fixedly installed on the surface of the vertical plate, the protrusion is movably installed on the surface of the blade, a guide block is movably installed at the bottom of the vertical plate, and a groove is provided on the surface of the guide block, the groove on the surface of the guide block being adapted to the blade.

[0015] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0016] 1. This utility model provides a utility knife with a fixing function, which adopts the cooperation of a shell, a first button, a movable plate, a guide post, a first spring, a limiting block, a pressure plate, a first anti-slip plate, a fixing block, and a second anti-slip plate. By setting a fixing block on the right side inside the shell and setting a second anti-slip plate on its surface, when the blade is pushed to a suitable length by the adjustment mechanism and used, the user holds the shell with their fingers and presses the first button, which pushes the pressure plate, causing the first and second anti-slip plates to clamp the blade. At the same time, the movable plate moves along the guide post, pulling the first spring until the movable plate contacts the limiting block. When the fingers are released, the first spring causes the movable plate to spring back to its original position. This device achieves a fixing effect by squeezing the blade, and conforms to the normal hand gripping action of a utility knife. It avoids inaccurate carving and cutting caused by blade movement, and also avoids the blade bending and breaking due to external force. In addition, the top width of the shell is narrower than the side width, which is convenient for hand gripping and improves the comfort and adaptability of the device.

[0017] 2. This utility model provides a utility knife with a fixing function, which adopts the cooperation of a slide rail, a slider, a vertical plate, a guide block, a protrusion, a slot strip, a second button, a base plate, a second spring, a fixed seat, a movable groove, and a locking post. By removing the back cover of the outer shell, the blade is placed on the protrusion on the surface of the vertical plate and inserted into the groove on the surface of the guide block. The groove on the surface of the guide block can prevent the blade from moving while also providing a guiding function. When the slider is inserted into the slide rail and it is necessary to push the blade forward, the second button is pressed. The base plate drives the locking post to move downward along the movable groove on the surface of the fixed seat, while stretching the second spring. At this time, the slider slides normally on the surface of the slide rail. When the second button is released, the second spring retracts and drives the locking post to engage in the slot of the slot strip, thus completing the fixing. Compared with the traditional sliding method of utility knives, this device reduces the noise during sliding and can be used in conjunction with the fixing mechanism to further fix the blade, improving the adaptability of the device.

[0025] Example 1

[0026] like Figures 1-5 As shown, this utility model provides a utility knife with a fixing function, including a blade 1. A fixing mechanism 2 is provided on the surface of the blade 1, and an adjusting mechanism 3 is provided on the surface of the blade 1. The fixing mechanism 2 includes a housing 201, which is movably mounted on the surface of the adjusting mechanism 3. A first button 202 is movably mounted on one side of the housing 201, with one end of the first button 202 extending into the interior of the housing 201. Movable plates 203 are fixedly mounted on both ends of the first button 202. Guide posts 204 are movably mounted on the surface of the movable plates 203. Two sets of guide posts 204 are provided, symmetrically distributed on the surface of the movable plates 203. The top of the guide posts 204... A limit block 206 is fixedly installed at one end. A first spring 205 is sleeved on the surface of the guide post 204. The two ends of the first spring 205 are fixedly connected to the outer shell 201 and the movable plate 203, respectively.

[0027] In this embodiment, a fixing block 209 is provided on the inside right side of the outer casing 201, and a second anti-slip plate 210 is provided on its surface. When the blade 1 is pushed to a suitable length by the adjustment mechanism 3 and used, the outer casing 201 is held by the fingers and the first button 202 is pressed, so that the first button 202 pushes the pressure plate 207, so that the first anti-slip plate 208 and the second anti-slip plate 210 clamp the blade 1. At the same time, the movable plate 203 moves along the guide post 204, pulling the first spring 205 until the movable plate 203 contacts the limiting block 206. When the fingers are released, the first spring 205 drives the movable plate 203 to rebound and reset. This device achieves a fixing effect by squeezing the blade 1, and conforms to the normal hand holding action of art knife. While avoiding inaccurate carving and cutting caused by the movement of the blade 1, it can also avoid the situation where the blade 1 bends and breaks due to the application of external force. In addition, the top width of the outer casing 201 is narrower than the side width, making the grip more comfortable and improving the adaptability of the device.

[0028] Example 2

[0029] like Figures 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the adjusting mechanism 3 includes a slide rail 301, which is disposed at the top of the outer shell 201. A slider 302 is movably mounted on the surface of the slide rail 301, and a fixed seat 310 is fixedly mounted on the bottom end of the slider 302.

When it is necessary to push the blade 1 forward, the second button 307 is pressed. The base plate 308 drives the locking pin 312 to move downward along the movable groove 311 on the surface of the fixed seat 310, while stretching the second spring 309. At this time, the slider 302 slides normally on the surface of the slide rail 301. When the second button 307 is released, the second spring 309 retracts, causing the locking pin 312 to engage in the slot of the locking strip 306, completing the fixation. Compared with the traditional sliding method of utility knives, this device reduces the noise during sliding and can work with the fixing mechanism 2 to further fix the blade 1. A fixing block 2 is set on the right side inside the outer casing 201. 09, and a second anti-slip plate 210 is provided on its surface. When the blade 1 is pushed to a suitable length by the adjustment mechanism 3 and used, the first button 202 is pressed by holding the outer shell 201 with the fingers, so that the first button 202 pushes the pressure plate 207, so that the first anti-slip plate 208 and the second anti-slip plate 210 clamp the blade 1. At the same time, the movable plate 203 moves along the guide post 204, pulling the first spring 205 until the movable plate 203 contacts the limit block 206. When the fingers are released, the first spring 205 drives the movable plate 203 to rebound and reset. This device achieves a fixing effect by squeezing the blade 1, and conforms to the normal hand holding action of art knife. While avoiding inaccurate carving and cutting caused by the movement of the blade 1, it can also avoid the situation where the blade 1 bends and breaks due to the application of external force. In addition, the top width of the outer shell 201 is narrower than the side width, making the grip more comfortable and improving the adaptability of the device.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
