Description

Technical Field

[0001] This utility model relates to the field of architectural decoration and cosmetic construction, and in particular to a rubber nozzle cutting tool. Background Technology

[0002] Glass sealant or cosmetic sealant is widely used in building decoration, home renovation, and cosmetic construction. The nozzles of these bottles typically need to be cut to the appropriate shape and size of the dispensing nozzle according to specific construction requirements. Currently, the tools used to cut the nozzles are mostly ordinary scissors or knives, which users manually operate. However, this method has the following problems: First, because the nozzle material is relatively hard and irregularly shaped, it is difficult to control the flatness of the nozzle during manual cutting, resulting in an irregular shape of the dispensing nozzle after cutting, which is difficult to meet the required precision in construction. Second, ordinary scissors or knives can easily cause burrs or cracks in the nozzle during the cutting process, affecting the uniformity of dispensing and the construction effect. Furthermore, existing tools usually cannot effectively flatten the nozzle before cutting, requiring users to take additional steps or use additional tools to adjust the nozzle shape, which is cumbersome and inefficient.

[0003] To address the aforementioned issues, some specialized cutting tools for cutting nozzles have emerged on the market. For example, cutting devices with fixed and movable blades can improve cutting stability to some extent. However, these tools still have shortcomings: firstly, existing tools lack the ability to adjust the flatness of the nozzle, making it difficult for users to precisely pre-process the nozzle before cutting, resulting in the size and shape of the outlet failing to meet diverse construction needs; secondly, the blade movement of existing tools is mostly direct cutting, lacking a structural design adapted to the nozzle shape, making it prone to deviation during cutting and affecting cutting accuracy. Therefore, there is an urgent need for a nozzle cutting tool with a simple structure and convenient operation, capable of flattening the nozzle before cutting by pressing the handle to ensure that the shape and size of the outlet after cutting meet construction requirements. Simultaneously, a linkage design between the handle and the blade should improve cutting accuracy and stability to overcome the shortcomings of existing technologies. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of existing technologies and to propose a nozzle shearing tool. To achieve the above objective, this utility model adopts the following technical solution:

[0005] A nozzle cutting tool is suitable for cutting bottle nozzles of silicone sealant or cosmetic glue. It includes a body, a handle, a blade, and a pressing handle. The body has a cutting opening. The pressing handle is pivotally connected to the body and is used to flatten the nozzle before cutting so that the cut nozzle meets the construction requirements. The handle is pivotally connected to the body and is equipped with a blade. When the handle is pressed, it can drive the blade to cut the nozzle inserted into the cutting opening.

[0006] Preferably, the pressing handle is provided with a pressing surface, and the main body is provided with a supporting surface opposite to the pressing surface; when the pressing handle is rotated, the pressing surface and the supporting surface cooperate with each other to clamp and flatten the nozzle.

[0007] Preferably, the cutting edge of the blade is arranged perpendicular to the axis of the nozzle.

[0008] Preferably, the pressing handle is positioned opposite to the knife holder.

[0009] Preferably, the pressing handle is provided with a locking mechanism to lock the pressing handle in the pressed position to maintain the state when the nozzle is flattened.

[0010] Preferably, the cut is a slit-shaped opening, the width of which matches the thickness of the flattened nozzle.

[0011] Preferably, a limiting structure is provided at the cutting opening to limit the depth of the nozzle extending into the cutting opening.

[0012] Preferably, one end of the handle is pivotally connected to the front end of the body, and the blade is located at the end of the handle near the cutting edge.

[0013] Preferably, a return spring is connected between the handle and the body so that the handle automatically returns to its initial position after being released.

[0014] Preferably, the blade is detachably mounted on the shank by fasteners.

[0015] Beneficial Effects: The nozzle cutting tool overcomes the problems of difficulty in controlling nozzle flatness, irregular nozzle outlet shape, and low operating efficiency in existing technologies by combining a main body, handle, blade, and pressing handle. Specifically, the pressing handle, pivotally connected to the main body and used to flatten the nozzle before cutting, effectively adjusts the nozzle flatness, ensuring the nozzle outlet shape and size precisely meet construction requirements. The handle, pivotally connected to the main body and equipped with the blade, drives the blade to cut the nozzle inserted into the cutting opening when the handle is pressed, achieving precise matching between the blade and nozzle, avoiding burrs and cracks caused by misalignment in traditional scissors or knives. The independent pivoting design of the pressing handle and the handle allows users to complete both nozzle flattening and cutting with a single tool, simplifying the construction process, significantly improving operating efficiency, and overcoming the cumbersome nature of existing technologies that require additional tools to adjust the nozzle shape. The cutting notch on the main body, along with the pressing handle and blade, works in synergy to ensure that the nozzle can be smoothly inserted and precisely cut after being flattened, enhancing the tool's stability and ease of use, and adapting to the needs of different construction scenarios.

[0027] Example 1

[0028] Please see Figures 1 to 7 The following detailed description of the nozzle cutting tool 10 of this utility model, in conjunction with specific embodiments, will enable those skilled in the art to understand and implement this utility model.

[0029] This embodiment provides a nozzle cutting tool 10, suitable for cutting bottle nozzles of silicone sealant or cosmetic adhesive. It includes a body 11, a handle 12, a blade 13, and a pressing handle 14. The body 11 is made of high-strength engineering plastic and is elongated. Its front end has a cutting slot 15, which is a slit-shaped or circular structure suitable for accommodating the flattened nozzle. The pressing handle 14 is mounted on the middle of the body 11 through a first pivot hole. A first pivot pin passes through the first pivot hole, and the pressing handle 14 is pivotally connected to the body 11 via the first pivot pin, allowing the pressing handle 14 to rotate around the first pivot pin. The pressing handle 14 has an elongated structure, and its inner side has a flat pressing surface 17 for squeezing the nozzle during rotation.

[0030] A blade holder 12 is mounted on the front end of the main body 11 via a second pivot hole. A second pivot pin passes through the second pivot hole, and the blade holder 12 is pivotally connected to the main body 11 via the second pivot pin, allowing the blade holder 12 to rotate around the second pivot pin. A blade mounting groove is provided at the end of the blade holder 12 near the cutting opening 15, and the blade 13 is fixed in the blade mounting groove by screws. When the blade holder 12 is pressed by an external force, it can drive the blade 13 to move downwards, cutting the nozzle inserted into the cutting opening 15.

[0031] The working process of this embodiment is as follows: First, the user inserts the nozzle of the glass glue or cosmetic glue bottle between the main body 11 and the pressing handle 14, so that the part of the nozzle to be cut is below the pressing handle 14; then, the user holds the main body 11 with one hand and presses the pressing handle 14 with the other hand, so that the pressing handle 14 rotates around the first pivot pin, and the pressing surface 17 of the pressing handle 14 gradually approaches the inner wall of the main body 11 to ensure that the shape of the glue outlet after cutting meets the construction requirements; next, the user presses the knife handle 12, so that the knife handle 12 rotates around the second pivot pin, and the knife handle 12 drives the blade 13 to move downward, and the cutting edge of the blade 13 passes through the cutting opening 15 to cut the flattened nozzle; after cutting, the knife handle 12 and the pressing handle 14 are released, and the nozzle is taken out, thus completing one cutting operation.

[0032] Through the above structural design, the nozzle cutting tool 10 of this utility model can effectively flatten the nozzle by pressing the handle 14 before cutting, and achieve precise cutting through the linkage of the handle 12 and the blade 13. The nozzle shape is regular, the operation is simple, and it is suitable for wide application in building decoration and beauty construction.

[0033] Example 2

[0034] This embodiment further optimizes the design based on Embodiment 1, providing an improved nozzle cutting tool 10 suitable for cutting bottle nozzles of silicone sealant or cosmetic adhesive. Its structure includes a main body 11, a handle 12, a blade 13, and a pressing handle 14. The main body 11 is made of high-strength engineering plastic and is elongated, with a cutting opening 15 at the front end. The cutting opening 15 is a slit-shaped structure suitable for accommodating the flattened nozzle. The pressing handle 14 is mounted on the middle of the main body 11 through a first pivot hole, and a first pivot pin passes through the first pivot hole, pivotally connecting the pressing handle 14 to the main body 11 via the first pivot pin. The handle 12 is mounted on the front end of the main body 11 through a second pivot hole, and a second pivot pin passes through the second pivot hole, pivotally connecting the handle 12 to the main body 11 via the second pivot pin. The blade 13 is fixed to the end of the handle 12 near the cutting opening 15 by a screw.

[0035] Preferably, the pressing handle 14 is provided with a pressing surface 17, which is a flat rectangular surface and is polished to reduce scratches on the nozzle. The main body 11 is provided with a support surface 18 opposite to the pressing surface 17. The support surface 18 is a plane parallel to the pressing surface 17 and forms a clamping space by cooperating with the pressing surface 17. When the user presses the pressing handle 14, the pressing handle 14 rotates around the first pivot pin, the pressing surface 17 and the support surface 18 move closer to each other and clamp the nozzle, applying uniform extrusion force to flatten the nozzle and ensure that the shape of the nozzle outlet after cutting meets the construction requirements.

[0036] Preferably, the cutting edge of the blade 13 is arranged perpendicular to the axis of the nozzle. The blade 13 is made of stainless steel and the cutting edge is formed by precision grinding. It maintains a 90-degree angle with the longitudinal axis of the nozzle, so that it can cut perpendicularly into the nozzle during shearing, reduce lateral deviation, and ensure the flatness and accuracy of the shearing surface.

[0037] Preferably, the pressing handle 14 and the knife handle 12 are arranged opposite to each other. The pressing handle 14 is located on the upper side of the main body 11, and the knife handle 12 is located on the lower side of the main body 11. The two are pivotally connected to the main body 11 by the first pivot pin and the second pivot pin, respectively. The opposite arrangement facilitates one-handed operation by the user. The user can press the pressing handle 14 with the thumb of one hand and press the knife handle 12 with the index or middle finger of the other hand to achieve continuous flattening and cutting actions.

[0038] The working process of this embodiment is as follows: First, the user inserts the nozzle between the clamping surface 17 and the supporting surface 18, so that the part to be cut is below the pressing handle 14; then, the user presses the pressing handle 14 with their thumb, and the clamping surface 17 and the supporting surface 18 cooperate to clamp and flatten the nozzle; next, the user presses the blade handle 12 with their index finger, and the blade handle 12 drives the blade 13 to move downward, and the vertical cutting edge of the blade 13 cuts the flattened nozzle; finally, the pressing handle 14 and the blade handle 12 are released, the nozzle is removed, and the cutting is completed. The above design improves the uniformity of flattening through the cooperation of the clamping surface 17 and the supporting surface 18, improves the cutting accuracy through the vertical cutting edge, and optimizes the operating feel by setting the pressing handle 14 and the blade handle 12 accordingly, making it suitable for various construction scenarios.

[0039] Example 3

[0040] This embodiment further optimizes the design based on Embodiments 1 and 2, providing an enhanced nozzle cutting tool 10 suitable for cutting bottle nozzles of silicone sealant or cosmetic adhesive. Its structure includes a main body 11, a handle 12, a blade 13, and a pressing handle 14. The main body 11 is made of high-strength engineering plastic and is elongated, with a cutting notch 15 at the front end. The pressing handle 14 is mounted on the middle of the main body 11 through a first pivot hole, and the handle 12 is mounted on the front end of the main body 11 through a second pivot hole. The blade 13 is fixed to the handle 12 with screws.

[0041] Preferably, the pressing handle 14 is provided with a locking mechanism 19, which includes a sliding latch mounted on the side of the pressing handle 14 and has protruding teeth. When the pressing handle 14 is pressed down to the flattened position of the nozzle, the teeth of the latch engage with a pre-set groove on the side of the main body 11, locking the pressing handle 14 in the pressed state, thereby maintaining the stability of the flattened nozzle and facilitating subsequent cutting operations.

[0042] Preferably, the cutting opening 15 is a slit-shaped opening that matches the thickness of the flattened nozzle, ensuring that the nozzle fits tightly against the cutting edge of the blade 13 when inserted into the cutting opening 15, reducing offset during the shearing process and improving the flatness of the nozzle.

[0043] Preferably, a limiting structure 20 is provided at the cutting opening 15. The limiting structure 20 consists of two protruding blocks, which are respectively provided on both sides of the cutting opening 15 to limit the depth of the nozzle into the cutting opening 15 to 10 mm, so as to prevent the nozzle from being inserted too deeply and causing the cutting position to be inaccurate.

[0044] Preferably, one end of the handle 12 is pivotally connected to the front end of the main body 11. Specifically, the tail end of the handle 12 is connected to the second pivot hole at the front end of the main body 11 through the second pivot pin. The blade 13 is disposed at one end of the handle 12 near the cutting opening 15. The blade mounting groove is located at the front end of the handle 12 to ensure that the blade 13 can be accurately aligned with the nozzle in the cutting opening 15 when pressed.

[0045] Preferably, a return spring is connected between the handle 12 and the body 11. The return spring is a compression spring, installed near the second pivot hole, with one end fixed to the bottom of the handle 12 and the other end fixed to the inner wall of the body 11. When the user releases the handle 12, the spring provides a return force to make the handle 12 automatically return to the initial position, which is convenient for repeated operation.

[0046] Preferably, the blade 13 is detachably mounted on the handle 12 by a fastener 22, which is an M3 screw. The blade mounting groove has a screw hole, and the screw passes through the corresponding hole on the blade 13 for fixing. The user can replace the worn blade 13 by loosening the screw to ensure the cutting effect for long-term use.

[0047] The working process of this embodiment is as follows: First, the user inserts the nozzle between the pressing surface 17 and the supporting surface 18, and then presses the pressing handle 14. The pressing surface 17 and the supporting surface 18 cooperate to flatten the nozzle, and the sliding lock engages in the slot to lock it in place. Next, the user presses the blade handle 12, which drives the blade 13 to cut the nozzle. After completion, the user releases the blade handle 12, and the return spring returns the blade handle 12 to its original position. Finally, the user releases the lock and removes the nozzle. The above design maintains the flattened state through the locking mechanism 19, the limiting structure 20 and the slit-shaped cutting opening 15 improve the cutting accuracy, and the return spring and detachable blade 13 enhance the ease of operation and durability.

[0048] In summary, the above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the scope of the present utility model.
