Abstract
Description
Technical Field
[0001] This utility model belongs to the field of cutting tool technology, and more specifically relates to a cutting tool. Background Technology
[0002] A knife is an everyday tool used for cutting objects. Its structure generally includes a handle and a blade connected to the handle. When using it, the blade is operated by holding the handle, making it convenient to cut.
[0003] In conventional cutting tools, the blade is typically fixed to the handle using a connecting pin. Both the handle and the connecting plate at the rear of the blade have mounting holes, which are aligned. During assembly, a slot is usually provided on the front of the handle. The connecting plate at the rear of the blade is inserted into this slot, and then the connecting pin is passed through the mounting hole in the handle and inserted into the mounting hole in the connecting plate. Finally, a special device is used to impact the connecting pin, ensuring a tight fit between the pin and the mounting holes in the handle and connecting plate, thus securing the blade to the handle. Alternatively, the handle can be divided into two opposing plates that clamp the connecting plate at the rear of the blade. The connecting pin is then passed through the mounting hole in the handle and inserted into the mounting hole in the connecting plate, and the connecting pin is again impacted using a special device to ensure a tight fit between the pin and the mounting holes in the handle and connecting plate, thus securing the blade to the handle.
[0004] However, existing knives still have the following shortcomings: 1. During assembly, the mounting holes of the blade's connecting plate and the handle need to be aligned so that the connecting nail can be inserted into both holes simultaneously. Furthermore, specialized equipment must be used to impact the connecting nail to ensure its stability, making assembly cumbersome. 2. Using specialized equipment to impact the connecting nail to ensure a tight fit with the handle and connecting plate makes it difficult to guarantee the flatness of the outer surface of the connecting nail against the outer surface of the handle after assembly. Unevenness between the connecting nail and handle surfaces affects the user's grip, requiring manufacturers to polish the wooden handle surface to maintain a smooth surface, increasing manufacturing steps. 3. After assembly, multiple connecting nails are visible on the left and right outer surfaces of the handle, affecting its aesthetics. Utility Model Content
[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a tool that is easy to assemble.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a cutting tool, including a handle and a blade connected to the handle, wherein the front end face of the handle is provided with an insertion port, the rear end of the blade is provided with a connecting piece, the connecting piece of the blade is inserted into the insertion port of the handle, the side wall of the handle is provided with a receiving groove, the bottom of the receiving groove is provided with an injection hole communicating with the insertion port, and the receiving groove has a sealing plate matching the shape of the inner side of the receiving groove.
[0007] In the above solution, a receiving groove is provided on the side wall of the tool holder, and an injection hole communicating with the insertion port is provided at the bottom of the receiving groove. When it is necessary to assemble the tool, the connecting piece of the blade can be inserted into the insertion port of the tool holder, and then glue is filled into the injection hole to enter the insertion port and stick together with the connecting piece. Then, a layer of glue is applied along the inner side of the receiving groove, and finally the sealing plate is installed into the receiving groove. Thus, the sealing plate is fixed in the receiving groove by the glue, and the connecting piece is fixed in the insertion port of the tool holder by the glue. In this way, the tool assembly operation can be completed. The entire assembly process of the knife can be completed manually without the need for any special equipment, making assembly convenient. Furthermore, after the receiving groove of the handle is sealed by the sealing plate, the outer side of the sealing plate remains flat with the outer side of the handle, ensuring a comfortable grip for the user. In addition, compared to existing knives where multiple connecting pins are exposed on the handle surface, the handle surface of this utility model only exposes a sealing plate, resulting in a simpler handle design that aligns with modern minimalist design principles and enhances the knife's aesthetic appearance.
[0008] Furthermore, the bottom of the aforementioned receiving groove has a through hole that communicates with the insertion port. A limiting post is provided on the side wall of the sealing plate corresponding to the position of the through hole, and a retaining groove is provided on the side wall of the connecting piece corresponding to the position of the limiting post. The limiting post passes through the through hole and engages with the retaining groove. This design, through the engagement of the limiting post and the retaining groove, ensures that the limiting post prevents the connecting piece from moving back and forth relative to the insertion port of the tool holder. This prevents the connecting piece from dislodging from the insertion port of the tool holder, allowing the adhesive to better fix the connecting piece to the insertion port of the tool holder, making tool assembly more convenient and stable.
[0009] Furthermore, the aforementioned limiting posts are provided in several quantities, and the number of through holes and slots is equal to the number of limiting posts. By using several limiting posts to cooperate with the slots of the connecting piece, the connecting piece can be more securely prevented from disengaging from the insertion port, thereby further improving the assembly stability of the tool.
[0010] Furthermore, the bottom of the aforementioned receiving groove is provided with an injection groove, and a fixing post is provided on the side wall of the sealing plate corresponding to the injection groove. The fixing post is placed in the injection groove. When installing the sealing plate, after applying a layer of glue to the inner side of the receiving groove, glue can be filled into the injection groove. Then the sealing plate is installed into the receiving groove, and the fixing post is placed in the injection groove. In this way, not only is the sealing plate bonded and fixed to the receiving groove by the glue, but the fixing post is also bonded and fixed to the injection groove by the glue, thereby improving the installation stability of the sealing plate.
[0011] Furthermore, the aforementioned connecting piece includes a front section and a rear section connected in sequence. The front section is connected to the rear end of the blade, and the width of the front section is greater than the width of the rear section. By increasing the width of the front section of the connecting piece, the structural strength of the front section of the connecting piece can be improved, so as to avoid the connecting piece from easily breaking during the use of the tool.
[0012] Furthermore, the aforementioned connector corresponding to the front section of the connector penetrates the upper side wall of the tool holder, and the upper side of the front section of the connector is flush with the upper side of the tool holder. This allows the front section of the connector to be wider, further improving the structural strength of the front section of the connector. Moreover, by setting the front section of the connector corresponding to the connector to penetrate the upper side wall of the tool holder, the connector can be inserted into the connector of the tool holder more easily and mate with the connector, making installation more convenient.
[0013] Furthermore, the aforementioned receiving groove is located on the upper side wall of the tool holder. The front side wall of the receiving groove is connected to the insertion port, and the rear side wall of the front section of the connecting piece abuts against the front side wall of the sealing plate. This prevents the connecting piece from swinging towards the sealing plate, thereby further improving the installation stability of the connecting piece.
[0014] Furthermore, the upper and lower side walls of the aforementioned tool holder are provided with receiving grooves, and each receiving groove is provided with an injection hole and a sealing plate. Both sealing plates are provided with limiting posts. This solution, by setting two sealing plates, allows the connecting piece to be simultaneously restricted by the limiting posts of the two sealing plates, thereby further improving the installation stability of the connecting piece.
[0015] Furthermore, the rear side wall of the aforementioned connecting piece has a through hole, so that when glue is filled into the socket, the glue can enter the through hole of the rear section of the connecting piece, thereby increasing the bonding range between the glue and the rear section of the connecting piece, which results in a better fixing effect on the connecting piece.
[0016] Furthermore, the handle is made of wood and the endplate is made of stainless steel. By using two different materials for the handle and endplate, the knife becomes more colorful and has a more unique appearance. In addition, the high strength of the steel makes the endplate less prone to breakage.
[0017] The beneficial effects of the cutting tool of this utility model are as follows: 1. The entire assembly process of the cutting tool can be completed manually without the need for special equipment to assist in the operation, making the assembly operation convenient.
[0018] 2. After the receiving groove of the handle is closed by the sealing plate, the outer side of the sealing plate can remain flat with the outer side of the handle, thus ensuring the user's comfort in gripping the handle.
[0019] 3. Compared to the design of existing knives where multiple connecting pins are exposed on the handle surface, the handle surface of this utility model knife only exposes a sealing plate, thus making the design of the handle surface simpler and making the knife of this utility model more in line with the modern minimalist design style, thereby making the appearance of the knife more beautiful.

For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.
[0028] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings:
[0029] Example 1
[0030] The structure of the cutting tool in this embodiment is as follows: Figure 1 , 2 As shown in Figure 3, the tool includes a handle 1 and a blade 2 connected to the handle 1. The front end of the handle 1 has an insertion port 11, and the rear end of the blade 2 has a connecting piece 21. The connecting piece 21 of the blade 2 is inserted into the insertion port 11 of the handle 1. The side wall of the handle 1 has a receiving groove 12. The bottom of the receiving groove 12 has an injection hole 121 that communicates with the insertion port 11, and the receiving groove 12 has a sealing plate 3 that matches the shape of the inner side of the receiving groove 12. In this embodiment, when assembling the knife, first insert the connecting piece 21 of the blade 2 into the socket 11 of the handle 1, then fill the glue injection hole 121 into the socket 11 and stick it together with the connecting piece 21. Then apply a layer of glue along the inner side of the receiving groove 12, and finally install the sealing plate 3 into the receiving groove 12. Thus, the sealing plate 3 is fixed in the receiving groove 12 by the glue, and the connecting piece 21 is fixed in the socket 11 of the handle 1 by the glue. In this way, the knife assembly operation can be completed.
[0031] Compared to existing knives, the assembly process of this embodiment can be completed manually without the need for additional specialized equipment, making the assembly operation more convenient. Furthermore, after the receiving groove 12 of the handle 1 is closed by the sealing plate 3, the outer surface of the sealing plate 3 remains flat with the outer surface of the handle 1, ensuring a comfortable grip for the user. In addition, compared to the existing knife handle designs that expose multiple connecting pins, the handle 1 of this embodiment only exposes the sealing plate 3, resulting in a simpler design that aligns with modern minimalist design principles and enhances the knife's aesthetic appearance.
[0032] As an improvement to this embodiment, the bottom of the receiving groove 12 is provided with a through hole 122, which communicates with the insertion port 11 of the tool holder 1. A limiting post 31 is provided on the side wall of the sealing plate 3 corresponding to the position of the through hole 122, and a slot 210 is provided on the side wall of the connecting piece 2 corresponding to the position of the limiting post 31. The limiting post 31 passes through the through hole 122 and cooperates with the slot 210. This solution, through the cooperation of the limiting post 31 and the slot 210, allows the limiting post 31 to prevent the connecting piece 21 from moving back and forth relative to the insertion port 11 of the tool holder 1, thereby ensuring that the connecting piece 21 of the blade 2 cannot come out of the insertion port 11 of the tool holder 1, so that the glue can better fix the connecting piece 21 to the insertion port 11 of the tool holder 1, making the tool assembly more convenient and stable.
[0033] Specifically, there are two limiting posts 31, and the number of through holes 122 and slots 210 is equal to the number of limiting posts 31. The two limiting posts 31 cooperate with the slots 210 of the connecting piece 21, which can more firmly prevent the connecting piece 21 from disengaging from the insertion port 11 of the tool holder 1, and further improve the assembly stability of the tool.
[0034] Example 2
[0035] This embodiment is a further improvement on the tool structure of Embodiment 1. The improvement lies in that, as... Figure 1 , 2 As shown in Figure 3, the connecting piece 21 includes a front section 211 and a rear section 212 connected in sequence. The front section 211 is connected to the rear end of the blade 2. The slot 210 is formed on the side wall of the rear section 212 of the connecting piece 21. The blade 2 is integrally formed with the front section 211 and the rear section 212 to ensure the connection stability between the connecting piece 21 and the blade 2. The width of the front section 211 of the blade 2 is greater than the width of the rear section 212. In this embodiment, by increasing the width of the front section 211 of the connecting piece 21, the structural strength of the front section 211 of the connecting piece 21 can be improved, so as to avoid the connecting piece 21 from easily breaking during the use of the tool.
[0036] Specifically, the aforementioned insertion port 11 corresponds to the front section 211 of the connecting piece 21 penetrating the upper side wall of the handle 1, and the upper side of the front section 211 of the connecting piece 21 is flush with the upper side of the handle 1. This allows the width of the front section 211 of the connecting piece 21 to be larger, further improving the structural strength of the front section 211 of the connecting piece 21. Furthermore, by setting the front section of the insertion port 11 to penetrate the upper side wall of the handle 1, the connecting piece 21 can be inserted into the insertion port 11 of the handle 1 more easily and cooperate with the insertion port 11, making installation more convenient.
[0037] In addition, the aforementioned receiving groove 21 is located on the upper side wall of the tool holder 1. The receiving groove 21 extends along the length of the tool holder 1 and is configured as a long strip structure. The front side wall of the receiving groove 21 is connected to the insertion port 11. The rear side wall of the front section 211 of the connecting piece 21 abuts against the front side wall of the sealing plate 3, so that the front side wall of the sealing plate 3 can prevent the connecting piece 21 from swinging towards the sealing plate 3, thereby further improving the installation stability of the connecting piece 21.
[0038] Example 3
[0039] This embodiment is a further improvement on the tool structure of Embodiment 2. The improvement is as follows: Figure 4 As shown, the upper and lower side walls of the aforementioned tool holder 1 are provided with receiving grooves 12, and each receiving groove 12 is provided with an injection hole 121 and a sealing plate 3. Each sealing plate 3 is provided with two limiting posts 31. In this embodiment, by providing two sealing plates 3, the limiting posts 31 of the two sealing plates 3 simultaneously restrict the connecting piece 21, thereby further improving the installation stability of the connecting piece 21.
[0040] As an improvement to this embodiment, such as Figure 2 , 4 As shown, the bottom rear end of the aforementioned receiving groove 12 is provided with an injection groove 123. The side wall of the sealing plate 3 is provided with a fixing post 32 corresponding to the position of the injection groove 123. The fixing post 32 is placed in the injection groove 123. When installing the sealing plate 3, after applying a layer of glue to the inner side of the receiving groove 12, glue can be filled into the injection groove 123. Then, the sealing plate 3 is installed into the receiving groove 12, and the fixing post 32 is placed in the injection groove 123. In this way, not only is the sealing plate 3 bonded and fixed to the receiving groove 12 by the glue, but the fixing post 32 is also bonded and fixed to the injection groove 123 by the glue, thereby improving the installation stability of the sealing plate 3.
[0041] In addition, the rear section 212 of the connecting piece 21 has a through hole 213 on its side wall. When glue is filled into the socket 11, the glue can enter the through hole 213 of the rear section 212 of the connecting piece 21, thereby increasing the bonding range between the glue and the rear section 212 of the connecting piece 21, which makes the fixing effect of the connecting piece 21 better.
[0042] As a preferred embodiment, the handle 1 is preferably made of wood, and the cover plate 3 is preferably made of stainless steel. By setting the handle 1 and the cover plate 3 to be made of two different materials, the knife has a richer color and a more unique appearance. In addition, the steel has good strength, making the cover plate 3 less prone to breakage.
[0043] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
