Description

Technical Field

[0001] This utility model belongs to the field of scissors technology, specifically relating to a pair of scissors with protective functions. Background Technology

[0002] Scissors, as a common cutting tool, are widely used in many fields such as daily life and industrial production. Their basic structure usually consists of two symmetrical blades connected by a pin. The blades are opened and closed by rotating around the pin, thus completing the cutting operation of various materials such as paper, cloth, and thread.

[0003] Existing traditional scissors, especially during children's craft activities or when beginners are using them, can easily cause cuts if fingers accidentally touch the blade due to a lack of sufficient operating experience and safety awareness. In industrial production settings, operators may also cause workplace injuries due to fatigue, distraction, or operational errors. However, when not in use, the exposed blade is not only prone to accidental cuts but may also be damaged by collisions and friction, affecting its performance. Although some scissors come with simple sheaths or storage boxes, they only provide some protection when not in use and cannot provide real-time protection after use. Utility Model Content

[0004] The purpose of this invention is to provide a pair of scissors with protective functions to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a pair of scissors with a protective function, comprising: a first scissor blade, one end of which is hinged to a second scissor blade via a hinge connector; A protective sleeve is fitted over the first and second scissor blades to cover the blades of the first and second scissor blades when not in use to prevent accidental contact and damage. The first handle is connected to one end of the first scissor blade, and the second scissor blade is connected to one end of the second handle. The first handle and the second handle are fixed together by a limiting component so that when the first handle and the second handle are in the closed state, they are fixed together to maintain the closed state. The blade is covered by a protective sleeve to prevent accidental contact, and the limiting component fixes the closed handle to maintain the state. Preferably, the limiting component includes a fixing frame, and a first protrusion and a second protrusion are respectively connected to the first handle and the second handle. The second protrusion is provided with a slot and the fixing frame is connected to the slot. The fixing frame and the two protrusions cooperate to provide a basis for the handle to be closed and fixed. Preferably, the fixing frame has two sets of V-shaped metal springs connected to it. One end of the first protrusion is connected to a circular locking block through a protruding post. One end of the circular locking block passes through the slot and is inserted between the two sets of metal springs to clamp and fix the circular locking block. The V-shaped metal springs clamp the circular locking block to achieve a stable fixation after the handle is closed. Preferably, a limiting post is connected between the two sets of metal springs to limit the excessive insertion of the circular locking block. The limiting post prevents the circular locking block from being excessively inserted and protects the metal springs from damage.

[0006] Preferably, the protective cover has a protective plate at the top and bottom, and a cleaning cloth is connected to the protective plate for wiping the first and second scissor blades. The cleaning cloth is used to wipe the scissor blades during storage to remove debris and maintain the blade performance. Preferably, the protective plate has a threaded groove in the middle, which provides a threaded fit structure for the connection between the protective plate and the protective sleeve. Preferably, the top and bottom mounting holes of the protective cover are provided with hand-tightening bolts, and one end of the hand-tightening bolt rotates through the mounting hole and is threaded into the threaded groove. The hand-tightening bolts enable the detachable connection between the protective plate and the protective cover, which is convenient for cleaning or replacing parts. Preferably, handle covers are fixedly fitted onto the first and second handles. The handle covers increase grip comfort and anti-slip properties, and improve operational stability.

[0007] Compared with the prior art, the beneficial effects of this utility model are: When not in use, the protective sleeve completely covers the blades of the first and second scissor blades, effectively preventing cuts from children, beginners, or operators due to accidental contact. It also prevents damage to the blades from collisions and friction during storage or transport. The retaining component firmly secures the first and second handles when closed, keeping the scissors closed. This not only ensures the protective sleeve stays stably on the blades when not in use, preventing it from falling off, but also allows the retaining component to close the first and second scissor blades after use, preventing accidental cuts from the open blades. Thus, the scissors provide real-time protection after use.

[0008] The top and bottom guards inside the protective case are connected to cleaning cloths. When the scissor blades are put into the protective case, the cleaning cloths will wipe the blades of the first and second scissor blades to remove dust, debris and other impurities from the blades, which helps to maintain the sharpness and performance of the blades and solves the problem of traditional scissors needing to be cleaned separately.

[0009] The protective plate is connected to the protective cover by a hand-tightening bolt. Loosening the hand-tightening bolt allows the protective plate to be removed from the protective cover, making it easy to clean or replace the cleaning cloth, ensuring cleaning effectiveness. It also facilitates cleaning the inside of the protective cover, extending its service life. Attached Figure Description

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0013] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed", "equipped with", "sleeved with", "connected", etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0014] This utility model provides, for example Figure 1-6 The scissors shown have a protective function, including: The first scissor blade 1 has a second scissor blade 3 hinged at one end via a hinge 2. The two scissor blades can rotate around the hinge 2 to open and close, thereby completing the cutting operation of various materials. The protective sleeve 4 is fitted onto the first scissor blade 1 and the second scissor blade 3. Its internal contour is adapted to the shape of the two scissor blades in the closed state. It can completely cover the blades of the first scissor blade 1 and the second scissor blade 3 when not in use. By forming a physical isolation barrier, it prevents personnel from accidentally touching the blades and causing damage, and at the same time prevents the blades from being damaged by external collisions and friction. The first handle 5 is connected to one end of the first scissor blade 1, and the second handle 6 is connected to one end of the second scissor blade 3. By holding the two handles, the corresponding scissor blades can be driven to open and close. The first handle 5 and the second handle 6 are fixed together by a limiting component. This limiting component can firmly lock the first handle 5 and the second handle 6 in the closed state, so that the scissors remain closed, ensuring that the protective cover 4 is stably worn when not in use, and preventing the scissor blades from opening after use and causing accidental cuts. The limiting component includes a fixing frame 7. A first protrusion 8 and a second protrusion 9 are respectively connected to the first handle 5 and the second handle 6. The second protrusion 9 has a slot adapted to the fixing frame 7. The fixing frame 7 is connected in the slot. The cooperation between the protrusion and the fixing frame forms a mechanical locking structure to fix the two handles in the closed state. The fixing frame 7 has two sets of V-shaped metal springs 10 fixedly connected inside. The metal springs 10 have good elastic deformation ability. One end of the first protrusion 8 is connected to a circular locking block 11 through a protrusion. One end of the circular locking block 11 is inserted between the two sets of metal springs 10 after passing through the slot. The metal springs 10 deform under the pressure of the circular locking block 11 and generate a reverse clamping force, thereby firmly clamping and fixing the circular locking block 11 to ensure reliable locking of the two handles in the closed state.

[0015] The two sets of metal springs 10 are connected by a limiting post 12 to limit the excessive insertion of the circular locking block 11. The limiting post 12 can abut against the end of the circular locking block 11 to prevent the circular locking block 11 from being inserted too deeply, causing the metal spring 10 to deform excessively and fail, thus ensuring the service life and locking stability of the limiting component.

[0016] The protective sleeve 4 is provided with a guard plate 13 at the top and bottom. A cleaning cloth 14 for wiping the first scissor blade 1 and the second scissor blade 3 is connected to the guard plate 13. The cleaning cloth 14 is made of absorbent microfiber material. When the scissor blades are put into the protective sleeve 4, they can fully contact the blade surface to remove dust, debris and other impurities from the blade and maintain the cleanliness and sharpness of the blade. The guard plate 13 has a threaded groove 15 in the middle. The threaded groove 15 provides a threaded fit structure for the connection between the guard plate 13 and the protective sleeve 4, which facilitates the detachable connection between the two. The protective sleeve 4 has a hand-tightening bolt 16 in the mounting holes at the top and bottom. The hand-tightening bolt 16 is easy to operate manually. One end of the bolt rotates through the mounting hole and is threaded into the threaded groove 15. The thread engagement achieves a stable connection between the protective plate 13 and the protective sleeve 4. The installation and removal of the protective plate 13 can be completed quickly by rotating the hand-tightening bolt 16. The first handle 5 and the second handle 6 are fixedly fitted with handle covers. The handle covers are made of non-slip and soft material, which can increase the comfort of holding, prevent the hand from slipping, and improve the stability and safety of operation.

[0017] When the scissors with protective function need to be used, the fixing components of the first handle 5 and the second handle 6 must be released first. In specific operation, the operator pinches the first handle 5 and the second handle 6 with his / her fingers and applies appropriate force to the outside, so that the circular locking block 11 on the first protrusion 8 gradually comes out from between the two sets of V-shaped metal springs 10 in the inner fixing frame 7 of the second protrusion 9. During this process, the V-shaped metal springs 10 will open slightly to both sides due to the external force of the circular locking block 11. After the circular locking block 11 is completely released, the metal springs 10 return to their original shape. At this time, the first handle 5 and the second handle 6 are no longer restricted and can rotate flexibly around the hinge 2. This allows the operator to hold the handle sleeves on the first handle 5 and the second handle 6 with both hands respectively, and move the first handle 5 and the second handle 6 closer or further apart by opening and closing their fingers. Since the first handle 5 is fixedly connected to the first scissor blade 1 and the second handle 6 is fixedly connected to the second scissor blade 3, the movement of the handles is synchronously transmitted to the scissor blades, so that the first scissor blade 1 and the second scissor blade 3 open and close and rotate around the hinge 2. When the two blades bite each other, they can cut materials such as paper, cloth, and thread. After use, the operator slowly closes the first handle 5 and the second handle 6, causing the blades of the first scissor blade 1 and the second scissor blade 3 to gradually come together. During the closing process, the first protrusion 8 moves with the first handle 5, and the circular locking block 11 on it gradually approaches the fixing frame 7 inside the second protrusion 9, eventually aligning with and inserting into the gap between the two sets of V-shaped metal springs 10. During insertion, the circular locking block 11 squeezes the inner side of the V-shaped metal spring 10, causing the spring to expand outward. After the locking block is fully inserted, the spring retracts inward due to its own elasticity, tightly clamping the circular locking block 11. At the same time, the end of the circular locking block 11 contacts the limiting post 12 to prevent over-insertion and structural deformation, thereby ensuring that the first handle 5 and the second handle 6 are stably in the closed state. Subsequently, the protective sleeve 4 is slipped onto the blades along their length. The inner wall of the protective sleeve 4 fits snugly against the sides of the blades. During the slip-on process, the cleaning cloth 14 on the guard plate 13 makes full contact with the blade surfaces of the first and second blades 1 and 3. As the protective sleeve 4 is pushed in, the cleaning cloth 14 thoroughly wipes the blades, removing any residual dust, debris, and other impurities. The protective sleeve 4 is secured to the guard plate 13 using a hand-tightening bolt 16. The bolt portion of the hand-tightening bolt 16 passes through the mounting hole on the protective sleeve 4 and engages with the guard plate 13. The threaded groove 15 in the middle engages precisely. By rotating the head of the hand-tightening bolt 16, the bolt is gradually tightened, thereby firmly fixing the guard plate 13 inside the protective sleeve 4. This fixing method ensures that the guard plate 13 and the cleaning cloth 14 will not shift inside the protective sleeve 4, ensuring that the protective sleeve 4 can tightly wrap the blade and continue to play a protective role when not in use. When the guard plate 13 needs to be disassembled later, the hand-tightening bolt 16 can be loosened to remove the guard plate 13 from the protective sleeve 4, making it convenient to clean or replace the cleaning cloth 14. The cleaning cloth 14 inside the protective case 4 is made of microfiber material. Microfiber material has a dense fiber structure that can absorb dust, debris and trace amounts of moisture on the blade surface through capillary action. It is also soft and will not damage the sharpness of the blade, making it suitable for everyday household use and maintaining a cleanliness level.
