Description

Technical Field

[0001] This application relates to the field of ear pick technology, and in particular to an ear pick. Background Technology

[0002] Currently, there are roughly the following methods for fixing the head and handle of ear picks: The first method is to tighten the head and handle with screws. This method is relatively cumbersome to install and remove, and there is a risk of them falling off if not tightened properly. The second method is to set a collar on the head with a groove, which fits into a protrusion on the handle. This method has poor fatigue strength and limited precision, and the protrusion and groove may loosen after repeated installation and removal. Utility Model Content

[0003] Therefore, it is necessary to provide an ear-cleaning spoon to address the problems of cumbersome disassembly and assembly and easy loosening of the current method of fixing the spoon head and handle.

[0004] An ear pick includes a spoon head and a spoon handle, one of the spoon head and the spoon handle including a telescopic structure, the telescopic structure being detachably sleeved on the other, the telescopic structure being for expanding when sleeved and for retracting when unsleeved.

[0005] In one embodiment, the spoon head includes a connected spoon portion and the telescopic structure, which is detachably sleeved onto the spoon handle.

[0006] In one embodiment, the telescopic structure has a hollow portion extending through its own axis, and the telescopic structure also has a cut communicating with the hollow portion. The cut is used to expand when the telescopic structure is fitted and to contract when the telescopic structure is unfitted.

[0007] In one embodiment, the cut is located at the middle of the telescopic structure along its own axial direction and extends through the outer peripheral surface of the telescopic structure.

[0008] In one embodiment, along the axial direction of the telescopic structure, the outer peripheral surface of the telescopic structure has opposing first and second edges, and the opening size of the cut along the circumferential direction of the telescopic structure gradually increases from the first edge of the outer peripheral surface toward the second edge.

[0009] In one embodiment, the cuts include a plurality of cuts, which are spaced apart circumferentially along the telescopic structure.

[0010] In one embodiment, the plurality of cuts includes a first cut and a second cut, wherein the opening size of the first cut gradually increases from the first edge toward the second edge in the circumferential direction of the telescopic structure, and the opening size of the second cut gradually increases from the second edge toward the first edge in the circumferential direction of the telescopic structure.

[0011] In one embodiment, the first cut and the second cut are staggered and spaced apart along the circumference of the telescopic structure.

[0012] In one embodiment, the telescopic structure has a limiting structure protruding into the hollow portion at one end along its own axial direction. The limiting structure is used to abut against the spoon head or the spoon handle when the telescopic structure is sleeved.

[0013] In one embodiment, the spoon handle includes a handle portion and a camera module, the handle portion having a receiving cavity, and the camera module being located within the receiving cavity.

[0014] The aforementioned ear pick features a telescopic structure, allowing the connection between the spoon head and handle to be completed with a simple fitting action. During installation, simply align the part with the telescopic structure and insert it into the other part. The telescopic structure automatically expands and deforms during the fitting process to adapt to the size of the connecting parts, eliminating the need for multiple rotations required for tightening screw threads. For example, when the handle is inserted into the end of the spoon head with the telescopic structure, the telescopic structure quickly wraps around the connecting part of the handle, completing the connection quickly. During disassembly, simply apply appropriate external force to separate the two parts, and the telescopic structure will retract, allowing the spoon head and handle to easily detach. Compared to traditional, complex fixing methods, this assembly and disassembly process is more direct and convenient, greatly improving user ease of use. The telescopic structure expands and fits tightly against the surface of the connecting parts during fitting. It adaptively adjusts and deforms according to the specific shape and size of the connecting parts of the spoon head and handle, tightly wrapping around the connecting parts and generating significant friction to effectively prevent the connection from loosening. Because the expansion of the telescopic structure is based on contact with the connecting parts, it can fill any tiny gaps that may exist between the connecting parts, making the connection between the spoon head and the handle more stable and less prone to loosening even under certain vibrations or external pulling forces. Since the telescopic structure can expand when fitting and contract when unfitting, it can dynamically adapt to different sizes of the spoon head and handle connecting parts. During the production process, even if there are certain dimensional tolerances in the connecting parts of the spoon head and handle, the telescopic structure can adapt to these differences through its own elastic deformation. For example, if the connecting part of the spoon head is slightly larger, the telescopic structure will expand fully to accommodate its size when fitting; if the size is slightly smaller, the telescopic structure can still fit tightly when contracting, thus effectively compensating for insufficient dimensional accuracy and ensuring a good fit. The telescopic structure adapts to the connecting parts through its overall expansion and contraction, distributing stress across the entire contact surface, avoiding fatigue damage caused by excessive local stress, and improving fatigue resistance. Therefore, the ear pick of this application, by setting a telescopic structure, can be easily disassembled and assembled, improve fatigue resistance, adapt to the connection position size of the spoon head and the spoon handle, improve the fitting accuracy, and reduce the phenomenon of loosening.

Detailed Implementation

[0020] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0021] Currently, there are roughly three ways to fix the head and handle of an ear pick: The first is to tighten the head and handle with screws. This method is cumbersome to install and remove, and there's a risk of it falling off if not tightened properly. The second method involves a collar with a groove on the head, which fits into a protrusion on the handle. During repeated installation and removal, the contact point between the groove and the protrusion experiences significant local stress. When subjected to external forces such as insertion, removal, or twisting, the stress concentrates at the edges of the groove and the corners of the protrusion, easily leading to excessive local stress and fatigue damage. Furthermore, the fixing of the groove and protrusion relies on the shape fit between them. During repeated installation and removal, the shapes of the protrusion and groove wear due to excessive friction and compression caused by stress concentration, loosening the fit, reducing precision, and causing it to come loose. The third method involves a vertical opening on the collar on the head, which fits onto the handle. This method also has poor fatigue strength and will loosen after several installations and removals.

[0022] Please see Figure 1To address the aforementioned problems, this application provides an ear pick 100, including a spoon head 1 and a spoon handle 2. One of the spoon head 1 and the spoon handle 2 includes a telescopic structure 12, which is detachably fitted onto the other. The telescopic structure 12 expands during fitting and retracts when disassembling. The ear pick 100 with the telescopic structure 12 allows the connection between the spoon head 1 and the spoon handle 2 to be completed through a simple fitting action. During installation, simply align the part with the telescopic structure 12 and insert it into the other part. The telescopic structure 12 will automatically expand and deform during fitting to adapt to the size of the connecting part, eliminating the need for multiple rotations required for tightening screw threads. For example, when the spoon handle 2 is inserted into the end of the spoon head 1 with the telescopic structure 12, the telescopic structure 12 can quickly wrap around the connecting part of the spoon handle 2, quickly completing the connection. During disassembly, simply apply appropriate external force to separate the two parts, and the telescopic structure 12 will retract, allowing the spoon head 1 and the spoon handle 2 to easily detach. Compared to traditional, complex fixing methods, this disassembly and assembly process is more direct and simple, greatly improving the ease of operation for users.

[0023] The telescopic structure 12 expands and fits tightly against the surface of the connecting part during insertion. It adaptively adjusts the degree of expansion according to the specific shape and size of the connecting part between the spoon head 1 and the spoon handle 2, ensuring a tight fit. This expansion generates a mutual pressing force between the telescopic structure 12 and the inserted part, resulting in significant friction and effectively preventing the connection from loosening. The telescopic structure 12 expands during insertion and contracts when released, ensuring its adaptability during each assembly and disassembly process. This keeps the connection in a suitable state at all times. This synchronized change avoids excessive friction caused by overly tight connections, thus preventing wear and loosening, and ensuring connection stability.

[0024] Since the expansion of the telescopic structure 12 is based on contact with the connecting parts, it can fill any tiny gaps that may exist between the connecting parts, making the connection between the spoon head 1 and the spoon handle 2 more stable and less prone to loosening even under certain vibration or external pulling. The telescopic structure 12 can dynamically adapt to different sizes of the extension parts 112 of the spoon head 1 and the spoon handle 2. During the production process, even if there are certain dimensional tolerances in the connecting parts of the spoon head 1 and the spoon handle 2, the telescopic structure 12 can adapt to these differences through its own changes. For example, if the connecting part of the spoon head 1 is slightly larger, the telescopic structure 12 will expand fully to accommodate its size when fitted; if the size is slightly smaller, the telescopic structure 12 can still fit tightly when contracted, thus effectively compensating for insufficient dimensional accuracy and ensuring a good fit. The telescopic structure 12 adapts to the connecting parts through its overall expansion and contraction, distributing stress across the entire contact surface, avoiding fatigue damage caused by excessive local stress, and improving fatigue resistance. Therefore, the ear pick 100 of this application, by setting the telescopic structure 12, can be easily disassembled and assembled, improve fatigue resistance, adapt to the connection position size of the spoon head 1 and the spoon handle 2, improve the fitting accuracy, and reduce the phenomenon of loosening.

[0025] Please see Figure 2 In an optional embodiment, a telescopic structure 12 can be provided on the spoon head 1, so that the telescopic structure 12 on the spoon head 1 is sleeved on the spoon handle 2. Alternatively, in other optional embodiments, a telescopic structure 12 can be provided on the spoon handle 2, so that the telescopic structure 12 on the spoon handle 2 is sleeved on the spoon head 1. Preferably, in some embodiments, the spoon head 1 includes a connected spoon portion 11 and a telescopic structure 12, and the telescopic structure 12 is detachably sleeved on the spoon handle 2. Providing a telescopic structure 12 on the spoon head 1, so that the spoon head 1 is sleeved on the spoon handle 2, facilitates gripping and connection. Furthermore, the spoon head 1 has a simple structure and can be used as a replacement part for future replacement; multiple spoon heads 1 can correspond to one spoon handle 2.

[0026] Please see Figure 2 In an optional embodiment, the spoon portion 11 includes a recessed portion 111 and an extended portion 112, with the recessed portion 111 and the telescopic structure 12 connected to both ends of the extended portion 112 along its length. The recessed portion 111 is hemispherical or semi-elliptical and is used to accommodate earwax. The extended portion 112 is an elongated column or cuboid shape and is used to extend the recessed portion 111 away from the telescopic structure 12.

[0027] In an optional embodiment, the telescopic structure 12 may be cap-shaped, i.e., a sleeve structure with one end open. Alternatively, in other optional embodiments, the telescopic structure 12 may be ring-shaped, i.e., a sleeve structure with both ends open.

[0028] Please see Figure 2In some embodiments, the telescopic structure 12 has a hollow portion 121 extending through it along its own axial direction. The telescopic structure 12 also has a slit 122 communicating with the hollow portion 121. The slit 122 is used to expand when the telescopic structure 12 is fitted and to contract when the telescopic structure 12 is unfitted. When the telescopic structure 12 is ready to be fitted onto another component (spoon head 1 or spoon handle 2), the component to be fitted first contacts the entrance of the hollow portion 121. Due to the presence of the slit 122, the slit 122 is equivalent to a pre-designed "opening". As the component to be fitted gradually enters the hollow portion 121, the component will exert outward pressure on the inner wall of the hollow portion 121. This pressure acts on the structures on both sides of the cut 122. Because of the presence of the cut 122, there is no complete annular structure to resist this outward force, allowing the portions on both sides of the cut 122 to be pushed open like a "door," thus expanding the telescopic structure 12. The expanded telescopic structure 12 can better adapt to the size of the fitted component, achieving a tight fit. When the fit is released, since there is no outward pressure from the fitted component, the structural characteristics of the telescopic structure 12 itself begin to function. The portions on both sides of the cut 122 are no longer subjected to outward spreading force, just like an opened "door" that has lost its external force pushing it back. At this time, the structures on both sides of the cut 122 will move towards their original positions due to the absence of continuous external force. From an overall structural perspective, the telescopic structure 12 will gradually retract along the cut 122, returning to its state before the fit. This is because, without external interference, the telescopic structure 12 tends to maintain its original, unexpanded structural form.

[0029] The telescopic structure 12 is provided with a notch 122. The presence of the notch 122 allows the telescopic structure 12 to expand during fitting, and this expansion can precisely adapt to the size of the fitted component (spoon head 1 or spoon handle 2). Because the notch 122 provides deformable space, the telescopic structure 12 can expand accordingly based on the actual diameter of the fitted component. For example, if the diameter of the fitted component is slightly larger than the original diameter of the hollow portion 121 of the telescopic structure 12, the expansion of the notch 122 allows the telescopic structure 12 to fit tightly onto the component, like a self-adjusting collar. Compared to a fixed-size fitting structure without the notch 122, this structure with the notch 122 better handles potential dimensional differences between components. Whether due to manufacturing tolerances or other reasons, dimensional changes can be effectively accommodated through the expansion of the notch 122, improving the compatibility between components.

[0030] During the fitting process, the notch 122 prevents the telescopic structure 12 from excessively compressing the fitted parts. Without the notch 122, if the telescopic structure 12 and the fitted parts are slightly mismatched in size, forced compression may occur, which could not only damage the parts but also affect the fitting effect. With the notch 122, the telescopic structure 12 can expand to adapt, avoiding problems such as part deformation or loose connection caused by excessive compression.

[0031] From an operational perspective, the notch 122 makes the fitting process easier. When the user inserts the fitting part into the hollow part 121 of the telescopic structure 12, the notch 122 allows the structure to expand, and the fitting can be completed without applying excessive external force. When installing the spoon head 1 and spoon handle 2 of the ear pick 100, the user can complete the operation more conveniently and quickly. Especially for situations where hand strength is limited or high operational precision is required, this structural advantage with the notch 122 makes installation easier.

[0032] The slit 122 helps maintain the overall stability of the telescopic structure 12 during expansion and retraction. During insertion, the expansion of the slit 122 allows the telescopic structure 12 to fit tightly against the outer surface of the inserted component, forming a stable connection. This tight fit is achieved through the adaptive expansion of the slit 122, preventing component wobbling or loosening due to a loose connection. For example, during the use of the ear pick 100, even with slight external force interference, the slit 122 ensures a stable relative position between the spoon head 1 and the handle 2 because it tightly connects the telescopic structure 12 to the inserted component. When the telescopic structure 12 retracts, the presence of the slit 122 allows it to better return to its original state and maintains a good connection tightness when inserted again. Because the slit 122 adjusts according to the shape and size of the inserted component during each expansion and retraction, the insertion effect between the telescopic structure 12 and the inserted component remains consistently good, preventing loosening due to repeated use.

[0033] Please see Figure 2 In an optional embodiment, one side edge of the telescopic structure 12 is connected to the extension portion 112 of the spoon portion 11.

[0034] Please see Figure 2 and Figure 3In optional embodiments, in some embodiments, the cut 122 is located in the middle of the telescopic structure 12 along its own axial direction and extends through the outer peripheral surface of the telescopic structure 12. In other optional embodiments, the cut 122 may be located on the two end peripheral surfaces of the telescopic structure 12 along its own axial direction. The former arrangement is preferred, as it allows for more uniform overall stress distribution: when the cut 122 is located on the outer peripheral surface of the telescopic structure 12, the external force acting on the telescopic structure 12 during the fitting and retraction processes will result in a more uniform stress distribution. Taking the fitting process as an example, when the spoon head 1 or spoon handle 2 is inserted into the hollow portion 121 of the telescopic structure 12, the cut 122 on the outer peripheral surface allows the structure to expand outward evenly, and the pressure can be distributed relatively evenly along the circumferential direction. If the cut 122 is not on the outer peripheral surface, it may cause stress concentration in a local area, causing the telescopic structure 12 to deform excessively in that area. The design of the cut 122 on the outer peripheral surface can avoid this situation, allowing the entire telescopic structure 12 to expand or retract in a coordinated manner in the circumferential direction. The cutout 122 on the outer circumference guides the structure to expand naturally in the circumferential direction, allowing each part to share a portion of the stress. When pressure is applied to the ring from the outside, the opening allows the ring to deform in a relatively uniform manner, rather than bearing excessive pressure at a weak point.

[0035] The slit 122 on the outer peripheral surface facilitates a tight fit between the telescopic structure 12 and the spoon head 1 or spoon handle 2. During connection, the slit 122 on the outer peripheral surface allows the telescopic structure 12 to better adapt to the shape of the component being connected. The slit 122 also allows the telescopic structure 12 to evenly wrap around the component like an elastic sleeve, ensuring a tight connection. This tight fit effectively prevents loosening or wobbling between the spoon head 1 and spoon handle 2 during use, improving the overall stability of the ear pick 100.

[0036] When the cut 122 is located on the outer peripheral surface, the user can clearly see the position and state of the cut 122. During the connection and disassembly process, this helps the user to better control the force and direction of operation. For example, the user can clearly see how the telescopic structure 12 expands and retracts through the cut 122 on the outer peripheral surface, thereby more accurately connecting or separating the spoon head 1 and the spoon handle 2.

[0037] Please see Figure 3In some embodiments, along the axial direction of the telescopic structure 12, the outer peripheral surface of the telescopic structure 12 has opposing first edges 123 and second edges 124. The opening size of the slit 122 along the circumferential direction of the telescopic structure 12 gradually increases from the first edge 123 towards the second edge 124. When the spoon head 1 or spoon handle 2 is inserted into the hollow portion 121 of the telescopic structure 12, this slit 122 with gradually increasing opening size acts as a guide groove. Starting from the first edge 123, the opening is smaller, and as the insertion process progresses towards the second edge 124, the opening gradually increases. This makes the insertion action easier to initiate because the smaller initial opening can provide preliminary positioning and guidance for the inserted part, thus effectively reducing resistance during insertion and allowing the user to connect the parts more easily and accurately during the fitting process. During the fitting process, as the inserted part compresses the telescopic structure 12, the stress gradually distributes from the first edge 123 towards the second edge 124. Due to the gradually increasing opening size, the stress can also be gradually dispersed along this direction. This gradual stress dispersion method can prevent stress concentration at a certain point or in a certain area. Compared with the uniformly sized cutout 122, it allows the telescopic structure 12 to bear pressure more evenly during the sleeve connection, reducing the possibility of excessive local deformation, thereby extending the service life of the telescopic structure 12.

[0038] After the connection is completed, the specially shaped cut 122 allows the telescopic structure 12 to better conform to the inserted component. Because the opening of the cut 122 changes from the first edge 123 to the second edge 124, the telescopic structure 12 can generate different degrees of clamping force at different positions according to the shape characteristics of the inserted component. The portion near the first edge 123 has a smaller opening and a relatively larger clamping force on the component, while the portion near the second edge 124 has a larger opening, providing a certain clamping force while better adapting to changes in the component's shape. This differentiated clamping force distribution makes the connection between the telescopic structure 12 and the inserted component tighter, effectively preventing loosening during use.

[0039] In an optional embodiment, the telescopic structure 12 may have one or more slits 122. When there are multiple slits 122, the number of slits 122 may be one, two, three, four, etc.

[0040] Please see Figure 3In some embodiments, the slits 122 include multiple slits 122, which are spaced apart circumferentially along the telescopic structure 12. When multiple slits 122 are spaced apart circumferentially along the telescopic structure 12, the external force can be more evenly distributed across the entire circumference during the fitting and retraction process. If there is only one slit 122, the stress will be mainly concentrated near this slit 122 during fitting, resulting in greater pressure in that area, while other parts will experience less stress distribution. The presence of multiple slits 122 allows the telescopic structure 12 to distribute stress evenly to various parts of the circumference when subjected to the pressure of the fitted component (spoon head 1 or spoon handle 2) being inserted. Multiple slits 122 can effectively prevent excessive local deformation, thereby extending the service life of the telescopic structure 12. Due to the uniform stress distribution, the material around each slit 122 will not be overstretched or damaged due to excessive stress. The circumferential distribution of multiple slits 122 allows the telescopic structure 12 to expand from multiple directions during fitting. When the shape of the component being fitted is not perfectly regular or there is a slight tilt during insertion, multiple cuts 122 can better accommodate this situation. For example, during insertion, if the component being fitted is slightly biased to one side, the cut 122 adjacent to that side can expand more easily to accommodate this deviation, rather than the single cut 122 which might be unable to accommodate this deviation, leading to fitting difficulties or damage to the component. During retraction, multiple cuts 122 also provide a more stable restoring force. When disengaging, the material around the multiple cuts 122 can work together to allow the telescopic structure 12 to retract more evenly to its original state. Compared to a single cut 122, the presence of multiple cuts 122 can reduce jamming or uneven shrinkage during retraction, ensuring that the telescopic structure 12 can smoothly return to its initial shape, preparing for the next fitting.

[0041] In an optional implementation, the multiple cuts 122 can be spaced at equal intervals or at non-equal intervals.

[0042] Please see Figure 3In optional embodiments, some embodiments include multiple cuts 122 including a first cut 1221 and a second cut 1222. The opening size of the first cut 1221 gradually increases from the first edge 123 towards the second edge 124 along the circumferential direction of the telescopic structure 12, and the opening size of the second cut 1222 gradually increases from the second edge 124 towards the first edge 123 along the circumferential direction of the telescopic structure 12. It is understood that the size changes of the first cut 1221 and the second cut 1222 are opposite, and this design of the cuts 122 in opposite directions can generate a bidirectional clamping force. After the connection is completed, the material around the first cut 1221 and the second cut 1222 will exert a center-to-center clamping force on the connected components due to elastic restoring force. Since the opening size changes of the two cuts 122 are in opposite directions, the clamping forces they generate are also in opposite directions, and this bidirectional clamping force enables a tighter connection between the telescopic structure 12 and the connected components. For example, when using the ear pick 100, even if subjected to some external vibration or slight pulling, this two-way clamping force can effectively prevent loosening between the spoon head 1 and the spoon handle 2, ensuring the stability of the connection.

[0043] In optional embodiments, in some embodiments, the first cut 1221 and the second cut 1222 are staggered along the circumference of the telescopic structure 12. It is understood that the arrangement of the first cut 1221 and the second cut 1222 can be: first cut 1221 - second cut 1222 - first cut 1221 - second cut 1222 - first cut 1221. In other optional embodiments, the first cut 1221 and the second cut 1222 can be randomly arranged; for example, the arrangement of the first cut 1221 and the second cut 1222 can be: first cut 1221 - first cut 1221 - second cut 1222 - second cut 1222 - first cut 1221. Preferably, the first cut 1221 and the second cut 1222 are staggered. The staggered arrangement can effectively prevent excessive deformation caused by local stress concentration. Because the opening dimensions of adjacent cuts 122 change in opposite directions, they restrain and balance each other under pressure. The staggered arrangement of the first cuts 1221 and the second cuts 1222 ensures that the material around each cut 122 maintains a reasonable degree of deformation under the balancing effect of adjacent cuts 122, thereby extending the service life of the telescopic structure 12. The staggered spacing of the first cuts 1221 and the second cuts 1222 generates a more comprehensive clamping force. After the connection is completed, the material around these staggered cuts 122 will exert a clamping force towards the center on the connected parts due to the elastic restoring force. Since the clamping forces of the first cuts 1221 and the second cuts 1222 are opposite in direction and staggered, this clamping force can act tightly on the connected parts from multiple angles, forming a more stable connection.

[0044] Please see Figure 2 In some embodiments, the telescopic structure 12 has a limiting structure 125 protruding inward from one end along its own axial direction toward the hollow portion 121. The limiting structure 125 is used to abut against the spoon head 1 or the spoon handle 2 when the telescopic structure 12 is fitted together. The limiting structure 125 is used to limit the fit when the spoon head 1 and the spoon handle 2 are fitted together, preventing overfitting.

[0045] Please see Figure 2 In an optional embodiment, a telescopic structure 12 is provided on the spoon head 1, and a limiting structure 125 is provided at the connection between the extension portion 112 of the spoon head 1 and the telescopic structure 12. When the spoon head 1 is sleeved on the spoon handle 2, the limiting structure 125 can abut against the end of the spoon handle 2 to prevent the sleeve length of the spoon handle 2 from being too long.

[0046] Please see Figure 2 In some embodiments, the handle 2 includes a handle 21 and a camera module 22. The handle 21 has a receiving cavity, and the camera module 22 is located inside the receiving cavity. By setting the camera module 22, the ear-cleaning spoon 100 can be visualized during ear cleaning, allowing the user to see the condition inside the ear canal, making the ear cleaning process safer and more efficient. The camera module 22 is a technical means well known to those skilled in the art and will not be described in detail here.

[0047] In an optional embodiment, the handle 21 may be a tubular structure made of materials such as steel, plastic, or aluminum alloy.

[0048] In summary, this application provides an ear pick 100. By setting a telescopic structure 12 on the spoon head 1, and opening symmetrical inverted V-shaped cuts 122 on the telescopic structure 12, the telescopic structure 12 is cut into an S-shape. The inverted V-shaped cuts 122 provide kinetic energy for the stretching and contraction of the telescopic structure 12, so that the telescopic structure 12 of the spoon head 1 forms a spring-like structure. The diameter of the entire telescopic structure 12 can be stretched and contracted smoothly, which can be smoothly adapted to the spoon handle 2 with a diameter tolerance of 0.03mm. This can improve fatigue resistance and achieve repeated disassembly and assembly without loosening.

[0051] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0052] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0053] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0054] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
