Description

Technical Field

[0001] This utility model belongs to the field of daily necessities technology, specifically relating to a multifunctional nut opener. Background Technology

[0002] Nuts are a common snack in daily life due to their rich nutritional value, but their shells need to be removed before consumption, and dealing with nut shells has always been a challenge for consumers. Furthermore, because there are many types of nuts, including sunflower seeds, peanuts, chestnuts, hazelnuts, pistachios, macadamia nuts, and pecans, different types of nut openers are needed. Currently, nut openers on the market have significant limitations and cannot meet the diverse needs of nut processing. The main problems are as follows: Existing tools are mostly designed for a single type of nut. For example, for macadamia nuts with pre-opened shells (the shells have been pre-processed by the manufacturer and have this opening), a special tool uses a metal pry bar to insert into the opening and pry open the hard shell. Chestnuts are usually shelled using ordinary scissors or special shellers. Scissors tend to crush the chestnut meat because the force is concentrated at one point, while special shellers are not compatible with other types of nuts such as macadamia nuts and sunflower seeds due to their fixed clamping structure. Sunflower seed shelling mostly relies on manual labor or the use of simple tools that can only crack thin shells. The clamping strength and spacing of these tools are not suitable for nuts with slightly harder shells (such as macadamia nuts and chestnuts). This results in consumers having to purchase multiple tools for different nuts, which increases usage costs and creates a burden on storage space. Utility Model Content

[0003] The purpose of this invention is to provide a multifunctional nut opener to solve the aforementioned problems in the prior art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A multifunctional nut opener includes: an opening pressure plate for applying pressure to nuts; an opening support plate for supporting nuts is hinged to one end of the opening pressure plate; a return spring is provided at the hinge between the opening pressure plate and the opening support plate, so that the opening pressure plate elastically returns to its open position under the action of the return spring after closing; a first inclined plate is installed at one end of the opening pressure plate near the hinge, and a second inclined plate is installed at one end of the opening support plate near the hinge; when the opening pressure plate is open, the first and second inclined plates overlap; when the opening pressure plate is closed, the first and second inclined plates are misaligned.

[0005] Furthermore, the edges of both the first and second inclined plates are treated with sharp edges, forming pointed corners.

[0006] Furthermore, a first cutting tool is fixedly connected to the opening pressure arm plate, and a second cutting tool that cooperates with the first cutting tool is fixedly connected to the opening support plate.

[0007] Furthermore, the first cutter is provided in two sets, and the two sets of the first cutter are arranged symmetrically in the width direction of the open pressure arm plate; the second cutter on the open support plate is provided in two sets corresponding to the first cutter.

[0008] Furthermore, a serrated assembly is provided between the two sets of the first cutters. The serrated assembly is fixedly connected to the open pressure arm plate, and the open support plate has a waist-shaped hole for avoiding the serrated assembly.

[0009] Furthermore, the sawtooth assembly consists of two tooth profiles: rounded teeth and pointed teeth.

Detailed Implementation

[0018] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the present utility model will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is used to help understand this utility model, but does not constitute a limitation on this utility model.

[0019] Example: like Figures 1-3 As shown, this embodiment provides a multifunctional nut opener, including: an opening pressure arm plate 1, which is used to apply pressure to the nuts, and an opening support plate 2 for supporting the nuts is hinged to one end of the opening pressure arm plate 1.

[0020] A return spring is provided at the hinge between the open pressure arm plate 1 and the open support plate 2, so that after the open pressure arm plate 1 is closed, it elastically returns to its original position and opens under the action of the return spring. The return spring can be a torsion spring, compression spring, leaf spring, square spring, etc.

[0021] In this embodiment, the reset spring 3 has a specific structure in which its middle part is embedded in the mounting groove 4, allowing it to rotate within the groove. The mounting groove 4 is located on the open support plate 2. The reset spring 3 has two ends: one end is slidably connected to the open pressure arm plate 1, and the other end is fixedly connected to the open support plate 2. The open pressure arm plate 1 is provided with a limiting groove 5 that cooperates with the mounting groove 4, limiting the sliding movement of the reset spring 3.

[0022] The mounting slot 4 provides the installation space and rotation basis for the return spring 3, while the limiting slot 5 effectively limits the sliding end of the return spring 3, preventing it from deviating from the predetermined movement trajectory during operation and ensuring the stability of its function. One end of the return spring 3 is slidably connected to the open pressure arm plate 1, and the other end is fixed to the open support plate 2. This connection method allows the return spring 3 to slide and rotate to a certain extent during operation to adapt to the movement of the open pressure arm plate 1, while the fixed end provides stable support for the return spring 3, enabling the elastic force of the return spring 3 to be effectively transmitted and drive the open pressure arm plate 1 to reset.

[0023] When the opening pressure arm plate 1 is closed by an external force, one end of the return spring 3 slides within the limiting range of the limiting groove 5 under the action of the opening pressure arm plate 1. At the same time, the return spring 3 itself will also rotate within the mounting groove 4. At this time, the return spring 3 deforms and stores elastic potential energy. When the external force disappears, the return spring 3 will release the elastic potential energy to return to its initial state, causing the opening pressure arm plate 1 to reset and open.

[0024] The open pressure arm plate 1 has a first inclined plate 6 installed at one end near the hinge, and the open support plate 2 has a second inclined plate 7 installed at one end near the hinge.

[0025] When the open pressure plate 1 opens, the first inclined plate 6 and the second inclined plate 7 overlap. When the open pressure plate 1 closes, the first inclined plate 6 and the second inclined plate 7 are misaligned. The misalignment generates squeezing force to crack nuts with slits (such as macadamia nuts).

[0026] Furthermore, in order to better insert the nut into the opening, the edges of the first inclined plate 6 and the second inclined plate 7 are both treated with sharp edges, forming pointed corners.

[0027] A first cutter 8 is fixedly connected to the open pressure plate 1, and a second cutter 9 that cooperates with the first cutter 8 is fixedly connected to the open support plate 2. The symmetrically matched cutter sets are fixed to the open pressure plate 1 and the open support plate 2 respectively, and crack the shell of nuts (such as sunflower seeds) by biting and clamping.

[0028] Two sets of first cutters 8 are provided, and the two sets of first cutters 8 are arranged symmetrically in the width direction of the open pressure arm plate 1; two sets of second cutters 9 are provided on the open support plate 2 corresponding to the first cutters 8.

[0029] A saw tooth assembly 10 is provided between the two sets of first cutters 8. The saw tooth assembly 10 is fixedly connected to the opening pressure arm plate 1. An oblong hole 11 is provided on the opening support plate 2 to avoid the saw tooth assembly 10 and prevent it from colliding with the opening support plate 2.

[0030] The serrated component 10 consists of two tooth shapes: rounded teeth 101 and pointed teeth 102. The pointed teeth 102 are used to pierce the nut shell, while the rounded teeth 101 on both sides are used to enlarge the opening to accommodate chestnuts.

[0031] There is one pointed tooth 102 and multiple rounded teeth 101, with the multiple rounded teeth 101 symmetrically arranged at both ends of the pointed tooth 102.

[0032] The other end of the open pressure plate 1 is vertically mounted with a third cutter 12, which can apply pressure to peanut nuts.

[0033] The other end of the open support plate 2 is fixedly connected to a pry bar 13, which is used to pry open the nut shell with the cut, or to dig out some kernels that are stuck inside the nut shell.

[0034] The pry bar 13 has a clearance groove 14 for avoiding the third cutting tool 12.

[0035] The first inclined plate 6 is provided with a first protrusion 15, and the opening support plate 2 is provided with a corresponding first chamfer 16, so that the first inclined plate 6 and the opening support plate 2 form a complete plane. The second inclined plate 7 is provided with a second protrusion 17, and the opening pressure arm plate 1 is provided with a corresponding second chamfer 18, so that the second inclined plate 7 and the opening pressure arm plate 1 form a complete plane.

[0036] Example 2: Opening a macadamia nut with a slit The open pressure plate 1 and the open support plate 2 open, one end of the return spring 3 is located outside the limiting groove 5, and the other end is around the mounting groove 4 to maintain the initial angle; the first inclined plate 6 and the second inclined plate 7 are spliced ​​into a flat plane through the non-fitting cooperation of the protrusion and chamfer, and placed into the cut of the macadamia nut.

[0037] Subsequently, the opening pressure arm plate 1 is pressed to rotate around the pin shaft, and the return spring 3 moves accordingly: one end slides away from the hinge point of the two, and the other end rotates around the mounting groove 4 (the mounting groove 4 provides a stable fulcrum). Through the transmission of the return spring 3, the opening pressure arm plate 1 and the opening support plate 2 are ensured to move synchronously. As the opening pressure plate 1 rotates, the first inclined plate 6 and the second inclined plate 7 gradually shift out of place. This shift generates a squeezing force that is precisely applied to the cut of the macadamia nut, opening the shell. During reset, the open pressure arm plate 1 is released, and the reset spring 3 slides and rotates in the opposite direction, causing the first inclined plate 6 to overlap and splice with the second inclined plate 7 to form a plane, thus completing the operation.

[0038] Example 3: Opening of seeds and nuts The opening pressure plate 1 and the opening support plate 2 open, and the return spring 3 drives the first cutter 8 and the second cutter 9 to separate, allowing the melon seeds to be put in. After the sunflower seed is placed between the two blades, press the opening pressure arm plate 1. The return spring 3 moves accordingly: one end slides towards the hinge point of the two blades, and the other end rotates around the mounting groove 4 to ensure that the opening pressure arm plate 1 and the support plate approach synchronously. The two blades gradually bite together: the first blade 8 and the second blade 9 are precisely connected, and the shell of the sunflower seed is cracked by the biting force (the stable transmission of the return spring 3 controls the uniformity of the force applied to avoid crushing the kernel). During reset, the reset spring 3 causes the cutter to separate and remove the sunflower seeds.

[0039] Example 4: Opening Chestnut-like Nuts The opening pressure plate 1 and the opening support plate 2 open, the saw tooth assembly 10 moves away from the opening support plate 2, and the waist-shaped hole 11 is located directly below the saw tooth, ready to avoid it. After the chestnut is placed on the opening support plate 2, the opening pressure plate 1 is pressed, and the return spring 3 drives the opening pressure plate 1 and the opening support plate 2 to move closer to each other in sync, and the saw tooth assembly 10 moves the opening pressure plate 1 downward; When the serrated assembly contacts the chestnut: the sharp teeth 102 first pierce the outer shell (playing the role of breaking the shell), and as it continues to move downward, the rounded teeth 101 contact the outer shell and widen the opening (playing the role of widening the opening); during this process, the serrated assembly 10 is always located inside the oblong hole 11 (the oblong hole 11 plays the role of avoidance to prevent collision). During reset, the reset spring 3 drives the sawtooth assembly 10 to move upward and disengage from the chestnut, thus completing the operation.

[0040] Example 5: Opening peanuts and chestnuts The open pressure arm plate 1 and the open support plate 2 are in an open state, and the return spring 3 is in the initial elastic potential energy storage state, which drives the third cutter 12 to be located outside the clearance groove 14 of the pry plate 13, and the two do not interfere with each other.

[0041] When using the third cutter 12 to open the chestnut, place the chestnut on the opening support plate 2. Then press the opening pressure plate 1. Under the stable transmission of the return spring 3, the opening pressure plate 1 moves smoothly downward, and the third cutter 12 moves downward accordingly. The third cutter 12, due to its structure and the pressure it receives, acts on the chestnut shell. Because the chestnut shell has a certain hardness, the third cutter 12 can use its cutting edge or pressure to cut or squeeze the chestnut shell, thereby forming an opening in the chestnut shell. Continuing to press the opening pressure plate 1 allows adjustment of the size and depth of the opening as needed to facilitate the subsequent removal of the kernel. After the chestnut is opened, release the opening pressure plate 1. The return spring 3 releases its elastic potential energy, causing the opening pressure plate 1 to move upward, and the third cutter 12 disengages from the clearance groove 14, completing the chestnut opening operation.

[0042] To open the peanut shell, place the peanut on the opening support plate 2. Then press down on the opening pressure plate 1. The return spring 3 precisely drives the opening pressure plate 1 to move downwards stably, and the third cutter 12 moves downwards with the opening pressure plate 1. The third cutter 12 applies pressure to the peanut shell, smoothly cutting the peanut shell to open the peanut and facilitate the removal of the peanut kernel. After opening the peanut, release the opening pressure plate 1. The return spring 3 drives the opening pressure plate 1 to move upwards, and the third cutter 12 disengages from the clearance groove 14, completing the peanut opening operation.

[0043] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
