Description

Technical Field

[0001] This utility model relates to the technical field of protective structure design for special equipment, and in particular to a protective cover for a manual electric push knife. Background Technology

[0002] In the fields of garment processing and fabric making, manual electric clippers are frequently used tools due to their high cutting efficiency and compatibility with various fabrics. Their core working component is a high-speed rotating blade, the exposed part of which directly contacts the fabric. Operators need to hold the handle to control the cutting trajectory, so blade protection is crucial to ensuring operational safety. Insufficient protection can easily lead to accidental finger contact with the blade, resulting in cuts, or fabric debris, especially synthetic fibers and wool fibers, can splash into the eyes and respiratory tract, causing safety accidents.

[0003] Most electric hair clippers rely solely on their built-in blade guards, which only cover the top of the blade, leaving the sides and bottom completely exposed. This makes it easy for operators to accidentally touch the blade when approaching from the side. Some added protective covers are fixed structures, such as welded or screw-fixed metal covers, whose dimensions and angles are perfectly matched to specific models. They cannot be installed when using electric hair clippers of different brands or blade lengths. Existing protective devices mostly use rigid plates, which, while providing high protection, obstruct the operator's view of the point of contact between the blade and the fabric, leading to a decrease in cutting accuracy, especially when cutting curved or corner shapes. Some protective plates have untreated edges, and the sharp corners can easily snag soft fabrics such as knitted fabrics and lace, causing fabric damage. A few adjustable protective devices are fixed with clips or simple screws, but they are prone to loosening under high-frequency vibration, causing the protective plate to wobble or even fall off, thus affecting the protective effect.

[0004] Existing manual electric knife protectors suffer from deficiencies in terms of comprehensive protection, compatibility with multiple machine models, ease of installation and disassembly, and operational compatibility, which have become pain points restricting the safety and efficiency of garment processing. There is an urgent need for a protective cover that can provide full-range protection, quick installation and disassembly, compatibility with multiple machine models, and non-interference with operation, thus solving the aforementioned industry problems.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a manual electric knife protective cover, including a body 1, a handle 2 fixedly connected to the lower part of the body 1, an auxiliary block 3 fixedly connected to one side of the body 1, a blade baffle 4 fixedly connected to the upper part of the auxiliary block 3, and a blade 5 disposed below the blade baffle 4. The baffle 4 is equipped with a drive assembly, and the output end of the drive assembly is fixedly connected to the blade 5. Therefore, the rotation of the blade 5 is achieved by the drive assembly. The body 1 is provided with a top fixing block 6. Rotating rods 7 are fixedly connected to both sides of the top fixing block 6. Fixed arms 8 are rotatably connected to each rotating rod 7. Soft pads 9 are fixedly connected to the inner side of the fixed arms 8. Connecting blocks 10 are fixedly connected to the other end of the fixed arms 8. Connecting bolts 11 are provided on the connecting blocks 10. Magnetic blocks 12 are fixedly connected to the connecting blocks 10. Baffle brackets 14 are provided on the magnetic blocks 12. The rotating rod 7 provides rotational support for the fixed arm 8. The user can rotate the fixed arm 8 around the rotating rod 7 to adjust the angle between the fixed arm 8 and the body 1, adapting to the contour curvature of the body 1 of different models, until the soft pad 9 on the inner side of the fixed arm 8 is completely in contact with the surface of the body 1. The soft pad 9 can fill the gap between the body 1 and the fixed arm 8, enhance friction and prevent the fixed arm 8 from sliding. A bottom plate 17 is provided under the handle 2. A plate fixing frame 18 is fixedly connected to the bottom plate 17. A plate clamp 19 is provided on the plate fixing frame 18. A connector 13 is provided on one side of the bottom plate 17. A screw 20 is fixedly connected to the connector 13. The screw 20 on the connector 13 can pass through the base plate 17, and the screw 20 is threaded with a nut 21; A magnetic block 12 is fixedly connected to the connector 13, a baffle frame 14 is provided on the magnetic block 12, a baffle 15 is provided on the baffle frame 14, and a buckle 16 is fixedly connected to the baffle 15. The tray plate 17 is fixed to the bottom of the handle 2 by engaging with the tray plate fixing bracket 18 and the tray plate clamp 19. The clamping tightness of the tray plate clamp 19 can be finely adjusted according to the diameter of the handle 2 to ensure that the bottom tray plate 17 fits the handle 2 without shaking. The connection piece 13 is fixed to the bottom tray plate 17 by the screw 20 to achieve core locking.

[0021] Working principle: The bottom fixing system is based on the bottom plate 17. It is fixed to the bottom of the handle 2 by the plate fixing bracket 18 and the plate clamp 19. The clamping tightness of the plate clamp 19 can be finely adjusted according to the diameter of the handle 2 to ensure that the bottom plate 17 fits the handle 2 without shaking. The connection between the connector 13 and the base plate 17 is secured by the screw 20: one end of the screw 20 is fixedly connected to the connector 13, and the other end passes through the base plate 17 and is threadedly connected to the nut 21. When the nut 21 is tightened, the nut 21 and the surface of the base plate 17 are tightly fitted together, and the connector 13 is firmly fixed to the base plate 17 by the friction of the threads, preventing relative displacement between the two, and maintaining stability even during high-frequency vibration operation of the machine body 1. If the position of the connector 13 needs to be finely adjusted, the nut 21 can be loosened to adjust its relative distance with the base plate 17. After it is in place, the nut 21 can be tightened again to fix it, taking into account both the reliability of the fixation and the adjustability of the position.

[0022] The top fixing block 6 is pre-fixed to the upper part of the machine body 1. The rotating rods 7 on both sides provide rotational support for the fixing arm 8. The user can rotate the fixing arm 8 around the rotating rod 7 to adjust the angle between the fixing arm 8 and the machine body 1 to adapt to the contour curvature of the machine body 1 of different models, until the soft pad 9 on the inner side of the fixing arm 8 is completely in contact with the surface of the machine body 1. The soft pad 9 can fill the gap between the machine body 1 and the fixing arm 8, enhance the friction and prevent the fixing arm 8 from sliding. Then, the angle of the fixing arm 8 is locked by the connecting bolt 11 on the connecting block 10. The connecting bolt 11 passes through the connecting block 10 and abuts against the side wall of the top fixing block 6, restricting the rotation of the rotating rod 7, so that the top fixing structure and the machine body 1 form a rigid connection, and prevent the fixing arm 8 from shifting during the cutting operation.

[0023] The baffle frame 14 serves as the mounting carrier for the baffle 15. It is fixed to the magnetic blocks 12 of the top connecting block 10 and the bottom connecting piece 13 by magnetic attraction blocks 12 at both ends. The magnetic connection requires no tools and can be quickly attached after alignment. The attraction force is ≥8N, ensuring that the baffle frame 14 will not fall off during operation. The baffle 15 is fixed to the baffle frame 14 by the buckle 16 on it. The buckle 16 is embedded in the slot of the baffle frame 14 and can be locked by pressing. After installation, the baffle 15 completely covers the exposed area of ​​the blade 5, forming a physical barrier from the top of the blade 5 to the bottom pressure foot. This not only prevents the operator from accidentally touching the high-speed rotating blade 5, but also intercepts the fabric debris generated during cutting, avoiding the debris from splashing and polluting the environment or cutting hands.

[0024] During use, if it is necessary to replace the blade 5 or clean up debris, the baffle frame 14 can be directly pried off the magnetic block 12 without disassembling the base plate 17 or the fixing arm 8, making maintenance convenient. After the operation is completed, the baffle frame 14 can be re-attached to its original position, and the buckle 16 will automatically engage the baffle 15 to restore the protective state. It is well-suited to the needs of high-frequency operation and intermittent maintenance in garment processing, and greatly improves operational safety without affecting cutting efficiency.
