Description

Technical Field

[0001] The utility model relates to the technical field of utility knives, in particular to a blade breaking device. Background Art

[0002] The thickness of utility knives varies depending on their models and manufacturers, but in general, their thickness is usually between 0.3 mm and 1 mm. Specifically: the blade thickness of a small utility knife may be thinner, such as some small blades suitable for ordinary light operations such as home or office, the blade thickness may be 0.38 mm, and the blade of a large utility knife may be thicker, such as the extra-large H blade suitable for difficult operations such as thick materials, the blade thickness may reach 0.7 mm, and the large blade suitable for various operations may have a blade thickness of 0.5 mm.

[0003] Tip breakage is a common problem during the use of utility knives, and a blade breaker is needed to deal with it. However, due to slight differences in the thickness of utility knife blades, which is usually between 0.3 mm and 1 mm, this poses a challenge to blade breaking. The utility knife blade breaking storage devices and blade breaking collection devices currently on the market use groove-shaped structure designs such as blade breaking ports, which aim to achieve the breaking function by applying appropriate shear force to the blades. However, the breaking port designs of these devices are often fixed and cannot adapt to blades of different thicknesses.

[0004] When a thinner blade is inserted into a relatively wide breaking mouth, due to the large space, at the moment of breaking, the blade may splash due to the extra space for movement, which may not only cause safety hazards, but also affect the accuracy and efficiency of the breaking operation. In addition, this fixed breaking mouth design may not be accurate and effective when applying shear force, thereby reducing the convenience of using the breaking device. Therefore, how to improve the adaptability and safety of the breaking device for utility knife blades of different thicknesses is a problem that needs to be solved at present. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a blade breaking device to solve the technical problem that when a thinner blade is inserted into a wider breaking mouth, at the moment of breaking, the thinner blade has a relatively large movement space, which easily causes the blade to splash.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a blade breaking device, comprising a device body, a bottom cover is provided at the bottom of the device body, a breaking groove is provided at the top of the device body, the breaking groove is used to insert the blade, a limiting mechanism is provided on one side of the breaking groove, a receiving groove is provided inside the device body, the limiting mechanism comprises an empty groove, a spring sheet, a pressure block, and a shift block, the spring sheet is provided in the empty groove, the pressure block is provided on one side of the spring sheet, and the side of the pressure block facing away from the spring sheet passes through the device body through a slide groove and is fixedly connected with a shift block.

[0007] By adopting the above technical solution, the mobility of the spring sheet enables the breaking device to flexibly adapt to blades of different thicknesses. When the blade is inserted into the breaking groove, the spring sheet can adjust its position to fit closely to the blade and provide stable support. This adaptive characteristic ensures that the device can effectively limit blades of various thicknesses.

[0008] Furthermore, the spring sheet and the pressing block are in an inclined surface abutment structure.

[0009] By adopting the above technical solution, the pressing block can press the spring sheet smoothly and continuously when moving, thereby realizing fine adjustment of the pressure of the spring sheet. The inclined abutment increases the contact area, disperses the pressure, and improves the stability and durability of the device.

[0010] Furthermore, a friction plate is provided on one side of the spring plate close to the breaking groove, and the surface of the friction plate and the inner wall of the breaking groove are both in contact with the blade.

[0011] By adopting the above technical solution, the friction between the blade and the blade is increased. When the blade is inserted into the breaking groove, the friction plate fits tightly against the surface of the blade, providing a firm clamping force and effectively preventing the blade from sliding or deflecting during the breaking process.

[0012] Furthermore, a plurality of friction blocks are arranged on the surface of the shift block.

[0013] By adopting the above technical solution, the shift block provides the user with an intuitive and convenient operation point for controlling the sliding of the pressure block. The user can easily adjust the position of the pressure block and then control the clamping force of the spring sheet on the blade by simply shifting the shift block, thereby simplifying the operation steps.

[0014] Furthermore, the bottom cover is plugged into the device body via a mounting seat.

[0015] By adopting the above technical solution, a convenient cleaning outlet is provided for the blade inside the receiving groove. When it is necessary to clean the broken blade fragments, the user can conveniently open the bottom cover to quickly clean out the fragments.

[0016] Furthermore, a magnetic block is provided inside the mounting seat for adsorbing the broken blade.

[0017] By adopting the above technical solution, the magnetic block can effectively absorb the broken blade to prevent it from scattering everywhere, which not only makes it easy to collect and handle the broken blade, but also avoids the possible damage to the environment and users caused by the blade fragments.

[0018] Furthermore, a protrusion is provided on one side of the bottom cover, and the protrusion is used to provide a supporting point for the user to act on the bottom cover.

[0019] By adopting the above technical solution, the protrusion provides the user with a clear and stable supporting point. When opening or closing the bottom cover, the user can conveniently apply force to the protrusion to easily operate the bottom cover. The protrusion increases the contact area between the hand and the bottom cover, making the operation more labor-saving and stable.

[0020] In summary, the utility model mainly has the following beneficial effects:

[0021] 1. The utility model uses the limit mechanism and the mobility of the spring sheet so that the device can automatically adapt to blades of different thicknesses. When the blade is inserted into the breaking groove, the spring sheet and the friction sheet will automatically adjust their positions according to the thickness of the blade and closely abut the blade to ensure its stability during the breaking process. At the same time, this structure enables the breaking device to better apply precise breaking force to the blade, because the blade is tightly fixed in the breaking groove. When the user applies the bending force, the force can be more concentrated and accurate, thereby improving the efficiency and success rate of the breaking, which not only improves the limit adaptability of the device to blades of different thicknesses, but also greatly increases the convenience of breaking the blade;

[0022] 2. The utility model provides a magnetic block which can effectively absorb the broken blades, which greatly simplifies the cleaning process and prevents the blade fragments from being scattered or lost. The absorption function keeps the working environment tidy and reduces the potential safety hazards caused by blade fragments. At the same time, the provision of the magnetic block also facilitates the user to uniformly handle the broken blades. Since the blades are tightly absorbed by the magnetic block, the user can easily collect and handle the blades, which not only improves work efficiency but also meets environmental protection requirements. In addition, the strong magnetism of the magnetic block ensures that the blades will not fall off easily even if the device shakes or tilts, further enhancing the safety of use.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0029] The following describes an embodiment of the utility model based on its overall structure.

[0030] Embodiment 1:

[0031] A blade breaking device, such as Figure 1-Figure 4 As shown, it includes a device body 1, a bottom cover 3 is provided at the bottom of the device body 1, a breaking groove 601 is provided at the top of the device body 1, the blade 2 is inserted into the breaking groove 601 when in use, a limiting mechanism 7 is provided on one side of the breaking groove 601, a receiving groove 602 is provided inside the device body 1, the limiting mechanism 7 includes an empty groove 701, a spring sheet 702, a pressing block 705, and a shifting block 706, the spring sheet 702 is provided in the empty groove 701, the pressing block 705 is provided on one side of the spring sheet 702, and the side of the pressing block 705 away from the spring sheet 702 passes through the device body 1 through the sliding groove 704 and is fixedly connected with the shifting block 706. In this embodiment, the mobility of the spring sheet 702 enables the breaking device to flexibly adapt to blades 2 of different thicknesses. When the blade 2 is inserted into the breaking groove 601, the spring sheet 702 can adjust its position to fit closely to the blade 2 and provide stable support. This adaptive characteristic ensures that the device can effectively limit blades 2 of various thicknesses. At the same time, through the flexible abutment of the spring sheet 702, the breaking device can ensure that the blade 2 remains stable during the breaking process, which is conducive to the user applying a more precise breaking force to the blade 2, which not only improves the adaptability to blades 2 of different thicknesses, but also makes the breaking operation more convenient and accurate.

[0032] See also Figure 3 , Figure 4The spring sheet 702 and the pressing block 705 are of an inclined abutment structure, so that the pressing block 705 can smoothly and continuously press the spring sheet 702 when moving, thereby realizing fine adjustment of the pressure of the spring sheet 702. The inclined abutment increases the contact area, disperses the pressure, and improves the stability and durability of the device. At the same time, the inclined abutment structure also enables the device to more flexibly adapt to blades 2 of different thicknesses. When the thickness of the blade 2 changes, the inclined abutment can automatically adjust the compression amount of the spring sheet to ensure that the blade 2 always obtains the appropriate clamping force. This adaptive feature simplifies the operation process, improves the user experience, and ensures the accuracy and efficiency of the breaking operation.

[0033] See also Figure 3 , Figure 4 A friction plate 703 is provided on the side of the spring plate 702 close to the breaking groove 601. The surface of the friction plate 703 and the inner wall of the breaking groove 601 are both in contact with the blade 2, which increases the friction between the blade 2 and the blade 2. When the blade 2 is inserted into the breaking groove 601, the friction plate 703 fits tightly against the surface of the blade 2, providing a firm clamping force, effectively preventing the blade 2 from sliding or deflecting during the breaking process. At the same time, the friction plate 703 and the inner wall of the breaking groove 601 are both in contact with the blade. This double contact structure further enhances the stability of the blade 2, which not only ensures the accuracy of the breaking operation, but also improves the safety of the operation and reduces the risk of accidental slippage of the blade.

[0034] See also Figure 1 , Figure 3 , Figure 4 The shift block 706 is used to provide the user with a sliding action point for the pressure block 705. The surface of the shift block 706 is provided with multiple friction blocks 707. The shift block 706 provides the user with an intuitive and convenient operation point for controlling the sliding of the pressure block 705. The user only needs to shift the shift block 706 to easily adjust the position of the pressure block, thereby controlling the clamping force of the spring sheet 702 on the blade 2, thereby simplifying the operation steps. At the same time, the multiple friction blocks 707 provided on the surface of the shift block 706 increase the friction between the user's hand and the shift block 706, ensuring that the hand will not slip during the operation, thereby improving the stability and accuracy of the operation, which not only improves the user experience, but also enhances the safety of the operation.

[0035] Embodiment 2:

[0036] See also Figure 1 , Figure 2 , Figure 3The bottom cover 3 is plugged into the device body 1 through the mounting seat 4, and is used to provide a cleaning outlet for the blade 2 inside the receiving groove 602, providing a convenient cleaning outlet for the blade 2 inside the receiving groove 602. When it is necessary to clean the broken blade 2 fragments, the user can easily open the bottom cover 3 to quickly clean out the fragments. At the same time, this plug-in mechanism also ensures a tight connection between the bottom cover 3 and the device body 1, effectively preventing the blade 2 fragments from leaking from the connection, ensuring the safety and cleanliness of use. In addition, the convenience of the plug-in mechanism also enables users to quickly disassemble and assemble when needed, thereby improving the maintainability and service life of the equipment.

[0037] See also Figure 1 , Figure 2 , Figure 3 A magnetic block 5 is provided inside the mounting seat 4 for adsorbing the broken blade 2. The magnetic block 5 can effectively adsorb the broken blade 2 to prevent it from scattering, which not only makes it easy to collect and handle the broken blade 2, but also avoids the possible damage to the environment and the user caused by the fragments of the blade 2. At the same time, the magnetic adsorption effect of the magnetic block 5 can ensure that the broken blade 2 will not be moved or lost at will, thereby improving the safety and cleanliness of the working area. In addition, the setting of the magnetic block 5 also makes it convenient for users to uniformly manage and recycle the broken blades, which is in line with the concepts of environmental protection and sustainable development.

[0038] See also Figure 1 , Figure 2 A protrusion 8 is provided on one side of the bottom cover 3 to provide a support point for the user to act on the bottom cover 3. The protrusion 8 provides the user with a clear and stable support point. When opening or closing the bottom cover 3, the user can conveniently apply force to the protrusion 8, thereby easily operating the bottom cover 3. The protrusion 8 increases the contact area between the hand and the bottom cover, making the operation more labor-saving and stable. At the same time, the setting of the protrusion 8 also improves the convenience and comfort of use. Since the protrusion 8 is conspicuous and easy to hold, the user can quickly and accurately find the support point without the need to search or grope laboriously, thereby improving the operating efficiency. The protrusion 8 can also prevent the hand from slipping to a certain extent, thereby enhancing the safety of operation.

[0039] The implementation principle of the utility model is: first, insert the end of the blade 2 to be broken into the inside of the breaking groove 601, then, turn the block 706 to cause the pressure block 705 on one side to move, and use the pressure block 705 to abut against the inclined surface of the spring sheet 702, so that the spring sheet 702 and the friction sheet 703 gradually approach one side of the blade 2, and cooperate with the inner wall of the breaking groove 601 to abut the blade 2, then, by applying a bending force to the blade 2, the blade 2 is broken. In this process, the mobility of the spring sheet 702 is used to cause the blade 2 to abut. With this structure, the limit adaptability of the breaking device to blades 2 of different thicknesses is improved, which is conducive to applying a more precise breaking force to the blade 2 and improving the convenience of breaking the blade 2.
