Description

Technical Field

[0001] This utility model relates to the field of broken blade technology, specifically a segmented blade breakage collection device. Background Technology

[0002] In scenarios such as manual cutting, office organization, and home renovation, segmented blades, commonly known as "break knives," are widely used because of their interchangeable sharp points. These blades are typically made of thin metal, with multiple pre-set grooves along the length of the blade surface, allowing them to cut different thicknesses of cardboard, foam board, and other materials.

[0003] When the blade wears down or needs to be adapted to different cutting depths, users can break off the discarded blade segment to expose a new, sharp blade segment and restore cutting performance. This segmented design significantly extends the overall lifespan of the blade and reduces the frequency of consumable replacements, making it an economical and practical cutting tool. However, existing break-off blades still have the following problems during use:

[0004] Firstly, when breaking the blade directly by hand, the blade fragments are likely to fly out and cause eye or skin cuts. Furthermore, uneven force applied manually can cause the blade to break along non-pre-set grooves, resulting in an irregular cutting edge that affects subsequent use. Secondly, existing auxiliary tools lack protective structures, so there is still a risk of flying fragments and accidental hand contact, making it difficult to meet the requirements for safe operation. Utility Model Content

[0005] The purpose of this invention is to provide a segmented blade breakage collection device. By using this device, the problems of existing broken blades being prone to breakage, difficult to accurately locate, and lacking protection can be solved.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a segmented blade breakage collection device, comprising a bin cover, an inlet at the center of the bin cover, magnetic blocks connected to both sides of the inlet, a rubber block at the center of the magnetic blocks, a threaded rod connected to the side of the bin cover, a gripping block connected above the threaded rod, a second adsorption magnet connected inside the bin cover, a first adsorption magnet connected below the second adsorption magnet, the first adsorption magnet being located above the outer shell, an mounting block connected to the center of the outer shell, a breakage opening at the center of the mounting block, and a protrusion connected to the inner side of the breakage opening.

[0007] Preferably, the connection between the cover and the threaded rod is a threaded connection, the connection between the threaded rod and the grip is a fixed connection, and a limit rod is connected to the other side of the cover. The height of the mounting block at the bottom is changed by using the threaded rod to facilitate the use of different sized breakers.

[0008] Preferably, the center of the hopper cover coincides with the center of the feed inlet, and magnetic blocks are symmetrically distributed on the feed inlet. The magnetic blocks are connected to the feed inlet by a rotating connection, which facilitates the fixation of the handheld part of the breaking knife through the feed inlet, thereby enabling the breaking operation.

[0009] Preferably, the magnetic block and the other magnetic block are mutually attracted, the magnetic block and the rubber block are staggered, and the magnetic block and the rubber block are fixedly connected. The magnetic block and the rubber block cooperate to automatically seal the feed port and fit it in the handheld part, preventing the blade from breaking and popping out.

[0010] Preferably, the first adsorption magnet is fixedly connected to the outer shell, the first adsorption magnet and the second adsorption magnet have a magnetic adsorption structure, and the second adsorption magnet is fixedly connected to the cover. By using the cooperation of the first adsorption magnet and the second adsorption magnet, the outer shell can be quickly fixed to achieve magnetic positioning.

[0011] Preferably, the connection between the breakout and the mounting block is a fixed connection, and the connection between the mounting block and the outer shell is a sliding connection. The inner side of the breakout has symmetrically distributed protrusions, which are used to fix the breakout blade and ensure that the breakout work is carried out after the breakout blade is bent.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. To prevent the blade from breaking, an automatic bonding protection mechanism is set up: By setting mutual magnetic blocks at the feed inlet, the magnetic blocks will automatically adhere to the hand-held part when the blade enters, thereby preventing the blade from breaking when it breaks. In addition, the opaque cover prevents the broken blade from being seen, reducing user resistance. Furthermore, the staggered rubber blocks ensure a good sealing effect.

[0014] 2. The protrusion ensures the positioning of the blade for quick and easy breaking: When the breaking blade is inserted into the breaking point, it will contact the protrusion. At this time, you will feel obvious resistance, which means that it has been inserted into the right position. The protrusion ensures positioning and prevents the breaking blade from moving. In addition, the mounting block has a liftable structure to ensure that breaking blades of different sizes can be fixed and broken. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0022] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 A segmented blade breakage and collection device includes a bin cover 1. A feed inlet 6 is located at the center of the bin cover 1, allowing broken blades to easily enter. Magnetic blocks 4 are connected to both sides of the feed inlet 6 to seal and prevent the blades from breaking off. A rubber block 5 is located at the center of each magnetic block 4 to ensure a tight seal and reduce gaps. A threaded rod 11 is connected to the side of the bin cover 1, allowing for the adjustment of the height of mounting blocks 8 to accommodate different blades. A gripping block 3 is connected above the threaded rod 11 for easy holding. A second adsorption magnet 10 is connected inside the bin cover 1. The second adsorption magnet 10 is used in conjunction with the first adsorption magnet 7 for quick fixation. The first adsorption magnet 7 is connected to the bottom of the second adsorption magnet 10. The first adsorption magnet 7 is connected to the outer shell 2, which facilitates the removal of the broken blade inside the outer shell 2. The first adsorption magnet 7 is located above the outer shell 2. The outer shell 2 stores the broken blade. The center of the outer shell 2 is connected to the mounting block 8, which receives the breakage opening 9 for easy breaking. The center of the mounting block 8 has a breakage opening 9 for breaking the blade. The inner side of the breakage opening 9 is connected to a protrusion 12 for precise positioning, reminding the blade to be inserted into the appropriate position.

[0023] The present invention will be further described below with reference to the embodiments.

[0024] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The connection between the cover 1 and the threaded rod 11 is a threaded connection, and the connection between the threaded rod 11 and the grip block 3 is a fixed connection. A limit rod is connected to the other side of the cover 1. The height of the mounting block 8 at the bottom is changed by using the threaded rod 11 to facilitate the use of different sized breakers.

[0025] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The center of the cover 1 coincides with the center of the feed inlet 6. Magnetic blocks 4 are symmetrically distributed in the feed inlet 6. The magnetic blocks 4 are connected to the feed inlet 6 by rotation. The feed inlet 6 facilitates the fixation of the handheld part of the breaking blade for breaking work. The magnetic blocks 4 and the other magnetic blocks 4 are mutually attracted. The magnetic blocks 4 and the rubber blocks 5 are staggered. The magnetic blocks 4 and the rubber blocks 5 are fixedly connected. The cooperation of the magnetic blocks 4 and the rubber blocks 5 makes the feed inlet 6 automatically seal and fit against the handheld part, preventing the blade from breaking and popping out. The breaking opening 9 is fixedly connected to the mounting block 8. The mounting block 8 is slidably connected to the outer shell 2. The inner side of the breaking opening 9 has symmetrically distributed protrusions 12. The protrusions 12 are used to fix the breaking blade and ensure that the breaking work is carried out after the breaking blade is bent.

[0026] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The first adsorption magnet 7 is fixedly connected to the outer shell 2. The first adsorption magnet 7 and the second adsorption magnet 10 have a magnetic adsorption structure. The second adsorption magnet 10 is fixedly connected to the cover 1. By using the cooperation of the first adsorption magnet 7 and the second adsorption magnet 10, the outer shell 2 is quickly fixed to achieve magnetic positioning.

[0027] Working principle: First, according to the width and thickness of the segmented blade to be broken, rotate the grip block 3 on the side of the cover 1. Since the grip block 3 is fixedly connected to the threaded rod 11, the rotation of the grip block 3 will drive the threaded rod 11 to rotate synchronously. Since the threaded rod 11 is rotatably connected to the mounting block 8, the rotation of the threaded rod 11 will be converted into the vertical lifting and lowering of the mounting block 8 along the inside of the outer shell 2. The limiting rod on the other side can restrict the mounting block 8 to rotate synchronously with the threaded rod 11 until the height of the breakout 9 in the center of the mounting block 8 is adapted to the current blade. For thin blades, the mounting block 8 needs to be lowered to shorten the lever arm, and for thick blades, the mounting block 8 needs to be raised to leave enough bending space.

[0028] Simultaneously, insert the break-off blade downwards from the feed inlet 6. Due to their mutual attraction, the magnetic blocks 4 on both sides of the feed inlet 6 will automatically adhere to the blade's handheld part. The rubber blocks 5, which are staggered on the magnetic blocks 4, will fill the gap between the magnetic blocks 4 and the blade, achieving automatic sealing of the feed inlet 6. Continue inserting the blade until the blade contacts the protrusion 12 on the inside of the break-off opening 9. At this point, the hand will feel obvious resistance, confirming that the blade has been accurately inserted into the break-off area. Finally, bend the handheld part. Because the protrusion 12 engages the blade, when the pressing pressure reaches the blade's breaking threshold, the discarded blade segment breaks along the preset indentation, completing the blade breaking operation. The magnetic blocks 4 and rubber blocks 5 at the feed inlet 6 will adhere tightly to the blade, preventing fragments from flying out of the feed inlet 6 during breaking. Furthermore, the cover 1 is opaque, which can prevent the user from directly seeing the blade breaking process, reducing resistance during operation and eliminating fear that prevents them from performing the breaking operation.
