Description

Technical Field

[0001] This utility model relates to the field of cutting tool technology, and in particular to a double-ended cutting tool. Background Technology

[0002] With the fast pace of modern life and the increasing popularity of outdoor activities, multifunctional portable kitchen utensils are being used more and more widely in scenarios such as home life, picnics, camping, and long-distance travel. Among them, double-ended fruit knives have become an important innovative direction in the field of everyday tools due to their unique functional integration. The typical structural design usually adopts a two-end functional partition scheme: one end is equipped with a curved peeler for peeling fruits and vegetables, and the other end is equipped with a cutter for cutting food into pieces, with a detachable sheath for safety protection. This design concept effectively integrates the functional modules of traditional fruit knives, peelers, and other tools, significantly improving the portability and space utilization of the product while ensuring basic usability.

[0003] However, current double-headed fruit knives have complex structures, are cumbersome to assemble, and are costly. For example, Chinese patent application CN202120566866.4 discloses "a double-headed fruit knife, including a blade connector, one end of which has a peeling part, and the other end of which has a cutting part. The peeling part includes a peeling sheath and a peeling blade, which are engaged with the blade connector. The cutting part includes a cutting sheath and a cutting blade, which are engaged with the blade connector. Based on existing fruit knives, it has two ends, one for peeling and the other for cutting, each end fitted with a protective sheath, and they are visually distinguishable. When using one end, pressing the unlock button on that end activates the other end's sheath, which functions as a handle. Each unlock button includes an unlock cap, a button spring, and a button base cover, which is interference-fitted with the blade connector." This patented technology has a complex structure, and the unlock button's spring-reset mechanism increases production and assembly costs.

[0004] Currently, some improvement solutions attempt to address these challenges through structural simplification. For example, magnetic sheaths are used instead of mechanical locking mechanisms. However, these alternatives present new drawbacks in terms of environmental adaptability (such as magnetic field interference) or cost control. Therefore, developing a novel double-ended tool structure that combines structural simplification, cost optimization, and improved reliability has become a key technical focus for those skilled in the art.

[0033] The present invention will be further described below with reference to embodiments.

[0034] This utility model embodiment proposes a double-headed cutting tool, referring to... Figures 1 to 6The connector includes: a connector 100, wherein the left and right ends of the connector 100 are respectively provided with a first cutter 110 and a second cutter 120, and the upper and lower surfaces of the connector 100 are respectively provided with a first mounting groove 130 and a second mounting groove 140, wherein the first mounting groove 130 is provided with a first slot 131 and a first slot hole 132, and the second mounting groove 140 is provided with a second slot 141 and a second slot hole 142, wherein the first cutter 110 is nested with a first cutter sleeve 150, and the second cutter 120 is nested with a second cutter sleeve 160; and a first button 200, wherein the front end of the first button 200 is provided with a first hook 210, and the end of the second cutter sleeve 160 connected to the first hook 210 is provided with a fourth slot hole 161, and the rear end of the first button 200 is provided with a first mounting groove 130 facing the first mounting groove 140. A first cantilever 220 and a second cantilever 230 extend in the direction of the groove 130. The free end of the first cantilever 220 is provided with a second hook 221 that engages with the first slot 132. The second cantilever 230 is embedded in the first slot 131 and secured. A second button 300 is provided with a third hook 310 at its front end. The end of the first blade sheath 150 connected to the third hook 310 is provided with a third slot 151. The rear end of the second button 300 is provided with a third cantilever 320 and a fourth cantilever 330 extending in the direction of the second mounting groove 140. The free end of the third cantilever 320 is provided with a fourth hook 321 that engages with the second slot 142. The fourth cantilever 330 is embedded in the second slot 141 and secured.

[0035] This embodiment provides a dual-headed cutting tool, including a connecting base 100, a first button 200, and a second button 300, which can realize the rapid switching and stable fixation of the dual-headed cutting tool.

[0036] The connecting seat 100 has a cuboid structure, with a first tool 110 (e.g., a cutting blade) fixedly mounted on its left end and a second tool 120 (e.g., a planer blade, which may have a blade and a tool holder, and the tool holder may be shaped like a blade). Figure 2 The C-shaped structure shown has the blades held at both ends of the C-shaped tool holder. It is possible that the tool holder and the connecting seat 100 are separate units, connected by means of fastening, rotation, or screws. The first tool 110 and the second tool 120 can be made of 304 stainless steel. The upper surface of the connecting seat 100 has a first mounting groove 130, and the lower surface has a second mounting groove 140, with the two mounting grooves symmetrically distributed.

[0037] The first mounting groove 130 has a horizontally extending first slot 131 and a first slot hole 132 located at the bottom of the first mounting groove 130; the second mounting groove 140 has a horizontally extending second slot 141 and a second slot hole 142 located at the bottom of the second mounting groove 140. It is possible that the first slot hole 132 penetrates the bottom plate of the first mounting groove 130, and the second slot hole 142 penetrates the bottom plate of the second mounting groove 140.

[0038] The first button 200 is an elongated button with a first hook 210 protruding outward at the front end for engaging with the blade sheath. Two cantilever arms extend from the rear end: the first cantilever arm 220 has a bent second hook 221 at its free end, which inserts into the first locking hole 132 to form a vertical limit; the second cantilever arm 230 is a laterally extending plate-like structure that can be inserted into the first locking groove 131 for horizontal fixation. Thus, the first cantilever arm 220 and the second cantilever arm 230 together form an elastic clamping structure. Pressing the first button 200 causes it to elastically deform, thereby releasing the locking of the first hook 210.

[0039] The second button 300 is symmetrical to the first button 200 in structure, with a third hook 310 at its front end and a third hook 310 at its rear end.

[0040] The third cantilever 320 has a fourth hook 321 at its free end, which is embedded in the second hole 142.

[0041] The fourth cantilever 330 is inserted into the second slot 141. The cooperation of the two cantilevers enables the second button 300 to form a bidirectional limit in the second mounting slot 140.

[0042] When it is necessary to change the tool: Press the first button 200, the first cantilever 220 and the second cantilever 230 remain in place, the end away from the first cantilever 220 and the second cantilever 230 retracts elastically, the first hook 210 disengages from the first tool sleeve 150, and the first tool 110 can be pulled out at this time.

[0043] Similarly, pressing the second button 300 removes the second blade sheath 160 and pulls out the second blade 120.

[0044] When installing the blade sheath, push the first blade sheath 150 or the second blade sheath 160 into the corresponding first hook 210 or third hook 310. The first hook 210 or third hook 310 slides into the limiting part of the blade sheath until you hear a "click" sound of the first hook 210 or third hook 310 locking, which means the fixing is complete.

[0045] The combination of the above slots and cantilever simplifies the assembly of the cutting tool.

[0046] In a preferred embodiment, two first cantilever arms 220 are provided, arranged side by side and perpendicular to the second cantilever arm 230. A first clearance gap 231 is provided between the second cantilever arm 230 and the two first cantilever arms 220 to avoid the groove wall of the first slot 131. Two third cantilever arms 320 are provided, arranged side by side and perpendicular to the fourth cantilever arm 330. A second clearance gap 331 is provided between the fourth cantilever arm 330 and the two third cantilever arms 321 to avoid the groove wall of the second slot 141.

[0047] In this embodiment, the width of the first slot 131 is adapted to the width of the second cantilever 230, and the depth of the first slot 131 is adapted to the body of the second cantilever 230, so as to secure the second cantilever 230 within the first slot 131. The width of the second slot 141 is adapted to the width of the fourth cantilever 330, and the depth of the second slot 141 is adapted to the depth of the third cantilever 320, so as to secure the fourth cantilever 330 within the second slot 141.

[0048] In a preferred embodiment, the first button 200 has a first pressing part 240 on the plate surface opposite to the first mounting groove 130. The first pressing part 240 is located at one end near the first hook 210 and protrudes from the plate surface of the first button 200. The second button 300 has a second pressing part 340 on the plate surface opposite to the second mounting groove 140. The second pressing part 340 is located at one end near the third hook 310 and protrudes from the plate surface of the second button 300.

[0049] In this embodiment, combined with Figure 3 and Figure 4 As shown, the first button 200 is provided with a first hook 210 that can be elastically deformed. On the front panel of the first button 200 facing away from the first mounting groove 130, a first pressing part 240 is integrally formed. The first pressing part 240 has a square boss structure, which makes it convenient for the operator to press with their fingers.

[0050] Correspondingly, the second button 300 is assembled with the connecting seat 100 through the second mounting groove 140, and the engagement direction of its second hook 221 is centrally symmetrical with that of the first hook 210. The front panel of the second button 300 is provided with a second pressing part 340, which forms a square boss structure near the root of the third hook 310. The top surface of the second pressing part 340 is machined with tool type indicator lines, and its edges are chamfered to ensure a comfortable feel during pressing.

[0051] When in use, when it is necessary to remove the blade sheath at one end, the operator presses down the first pressing part 240 or the second pressing part 340. Since the first pressing part 240 or the second pressing part 340 is set close to the corresponding first hook 210 or third hook 310, the pressing torque can be effectively amplified through the lever principle, causing the first hook 210 or the third hook 310 to undergo elastic deformation, thereby achieving smooth disengagement.

[0052] In a preferred embodiment, the end of the first blade sheath 150 that abuts against the first pressing part 240 is further provided with a first recess 152, which is used to hold the first pressing part 240; the end of the second blade sheath 160 that abuts against the second pressing part 340 is further provided with a second recess 162, which is used to hold the second pressing part 340.

[0053] In this embodiment, combined with Figure 1 , Figure 5 and Figure 6 As shown, the first blade sheath 150 and the second blade sheath 160 can be made of plastic, making them lightweight. A first recess 152 and a second recess 162 are formed at the opening near the handle end. These recesses have a U-shaped structure, and their opening width and depth are adapted to the shape of the protrusion of the first pressing part 120, ensuring stable locking.

[0054] In use, the operator presses down the first pressing part 240 or the second pressing part 340, and the first hook 210 or the second hook 221 disengages from the blade sleeve, allowing the blade sleeve to slide along the axial direction to achieve the opening action.

[0055] In a preferred embodiment, such as Figure 3 and Figure 4 As shown, the inner wall of the first slot 131 is provided with a first limiting rib 131a, and the inner wall of the second slot 141 is provided with a second limiting rib 141a.

[0056] In this embodiment, several first limiting ribs 131a and second limiting ribs 141a extending towards the bottom of the groove are symmetrically arranged on the left and right sides of the groove walls of the first groove 131 and the second groove 141. The top ends of the first limiting ribs 131a and the second limiting ribs 141a are provided with guide slopes extending towards the middle. The spacing of the first limiting ribs 131a is adapted to the thickness of the second cantilever 230, and the spacing of the second limiting ribs 141a is matched to the thickness of the fourth cantilever 330.

[0057] In a preferred embodiment, such as Figure 5 and Figure 6 As shown, the tail of the first blade sleeve 150 or the second blade sleeve 160 is provided with a hanging ring 170, the fixed end of the hanging ring 170 is provided with a first locking strip 171 and a second locking strip 172, and the tail of the first blade sleeve 150 or the second blade sleeve 160 is provided with a fixing hole 163, which is engaged between the first locking strip 171 and the second locking strip 172.

[0058] In this embodiment, the second locking strip 172 and the first locking strip 171 are arranged in parallel. During installation, the hanging ring 170 is inserted into the fixing hole 163 with an interference fit, and locking is achieved by the elastic deformation of the second locking strip 172 and the first locking strip 171.

[0059] In a preferred embodiment, such as Figure 3 and Figure 4 As shown, a first reinforcing rib 222 is provided between the inner surface of the first cantilever 220 and the first button 200, and a second reinforcing rib 322 is provided between the inner surface of the third cantilever 320 and the second button 300.

[0060] In this embodiment, the first reinforcing rib 222 and the second reinforcing rib 322 adopt a triangular plate-shaped structure design and are integrally formed with the first cantilever 220 and the third cantilever 320 body.

[0061] In a preferred embodiment, such as Figure 2 As shown, the second tool 120 is a planer, which includes a tool holder 121 and a blade 122. The tool holder 121 is integrally formed with the connecting seat 100.

[0062] In this embodiment, the blade holder 121 may be made of plastic, or possibly, the blade holder 121 and the connecting seat 100 may be integrally formed, while the blade 122 may be made of metal, such as stainless steel. The blade 122 is snapped onto the blade holder 121 and can rotate within a certain angle on the blade holder 121 to facilitate peeling fruits, etc.
