Description

Technical Field

[0001] This utility model specifically relates to a multifunctional sampling pliers. Background Technology

[0002] In customs inspection and quarantine, random sampling of live samples is a crucial task, especially when inspecting and quarantining imported and exported animals and their products. Accurately and compliantly collecting representative samples is essential. To ensure that imported and exported animals and animal products meet national quarantine and food safety requirements, it is usually necessary to sample and test different categories of products. This typically involves obtaining appropriate sampling sizes from various sample types for further testing. However, due to different sample types and testing requirements, the required sampling sizes and shapes often vary.

[0003] Traditional sampling pliers have a simple design and fixed function, making them unable to adapt to diverse sampling requirements. The fixed blade shape of these traditional tools cannot be adjusted according to actual needs, thus limiting their applicability in various environments. For example, a curved blade may be needed to obtain the best sampling effect when processing soft tissue samples, while a straight blade may be necessary when cutting plant samples.

[0004] In addition, sampling tools must be strictly disinfected after use to prevent cross-contamination between microbial products. This places higher demands on the materials and technology of the sampling tools. Due to the limitations of the sampling site conditions, heating is often used as a simple disinfection method. However, without auxiliary equipment, it is impossible to visually observe whether the heating is sufficient.

[0005] This utility model was developed precisely because of the aforementioned shortcomings. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a convenient and adaptable multifunctional sampling pliers.

[0007] This utility model is achieved through the following technical solution:

[0008] This utility model provides a multifunctional sampling pliers, comprising: two symmetrically arranged pliers, rotatably connected and forming an intersection; at least two sets of scissor heads, each pliers head including two symmetrically arranged scissor heads, each scissor head being detachably connected to a corresponding pliers; a reset elastic element between the two pliers, allowing them to close and open; when the reset elastic element is in its natural state, the two pliers are in their initial state; when the reset elastic element is in its compressed state, the two pliers are in their closed state; and when the reset elastic element is in its stretched state, the two pliers are in their extended state; a locking structure is provided between the scissor heads and the pliers to fix the former to the latter; and an unlocking structure is provided between the two pliers to unlock the locking structure when they are in their extended state.

[0009] As described above, the multi-functional sampling pliers have mounting holes on the pliers and mounting pins on the pliers head that can be inserted into the mounting holes, so that the pliers head and the pliers head can be detachably connected.

[0010] As described above, the multi-functional sampling pliers have a spring clip connected to the mounting pin, and the locking structure includes a snap-fit ​​part on the spring clip and a snap-fit ​​groove in the mounting hole that snaps into the snap-fit ​​part to prevent the mounting pin from coming out.

[0011] As described above, the unlocking structure of the multi-functional sampling pliers includes an arc-shaped groove disposed on the pliers and communicating with the locking groove, and a push rod disposed on the pliers and capable of being inserted into the arc-shaped groove of another pliers. The center of the arc-shaped groove is consistent with the rotation center of the two pliers, so that when the two pliers are closed and opened, the push rod of the pliers slides in the arc-shaped groove of the other push rod. Furthermore, when the two pliers are in the unfolded state, the push rod reaches the locking groove and is used to push out the locking part.

[0012] The multi-functional sampling pliers described above have a cutting edge on the cutting head, and a scale marking is also provided on the cutting head along the cutting edge.

[0013] As described above, in the multi-functional sampling pliers, the reset elastic element is a spring that connects to two pliers at both ends.

[0014] The multi-functional sampling pliers described above have a thermochromic coating on the surface of the pliers head.

[0015] The thermochromic coating of the multifunctional sampling cutter described above is a metal oxide multilayer interference film.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. Versatile adaptability: By providing a variety of shaped scissor heads, it can adapt to the sampling needs of different sample types and sizes, greatly improving the applicability and flexibility of the tool.

[0018] 2. Convenient operation experience: The detachable design allows users to quickly replace the scissor head assembly, simplifying the sampling preparation process for different samples and improving work efficiency. The locking and unlocking structures ensure a firm connection between the scissor head and the scissor clamps, while facilitating disassembly and cleaning, ensuring long-term stability and reliability.

[0019] 3. Enhanced safety and hygiene standards: The thermochromic coating on the surface makes the sterilization process more intuitive, allowing for direct observation of whether the heating is sufficient and uniform. This ensures that the pliers have reached the appropriate sterilization temperature before each use, effectively reducing the risk of cross-contamination between microorganisms. At the same time, the pliers, due to their high temperature after heat sterilization, cannot be used directly for sampling, otherwise the original microorganisms in the sample will be disinfected. Therefore, they need to be cooled before sampling again. The use of the thermochromic coating on the surface makes it easy for users to observe whether the pliers have reached the low temperature standard for reuse.

[0020] 4. Intuitive size identification: The scale markings on the scissor head, arranged along the scissor blade, help operators to more accurately control the size and shape of the sample during the sampling process, thereby improving the sampling quality.

[0021] 5. Easy to maintain and service: Since the scissor head assembly can be easily disassembled and replaced, it becomes simpler to clean, disinfect, or replace specific parts of the entire device, extending the service life of the equipment and reducing maintenance costs.

[0022] 6. Improved inspection accuracy: By accurately matching the required sampling specifications for various types of samples, the accuracy and reliability of subsequent analysis results were ensured, providing strong technical support for the customs center. Attached Figure Description

[0028] The utility model will be further described below with reference to the accompanying drawings:

[0029] The orientations described in this utility model specification, such as "up," "down," "left," "right," "front," and "back," are based on the orientations in the accompanying drawings and are intended to facilitate the description of the relationships between the various components. They do not indicate the unique or absolute positional relationships between the various components, but are merely one embodiment of the utility model and are not a limitation on its implementation.

[0030] This embodiment introduces a multifunctional sampling pliers, such as... Figure 1 and Figure 2 As shown, the device includes a symmetrically arranged pair of scissor clamps 1, which are rotatably connected and intersecting each other; it also includes at least two sets of scissor head assemblies 200, each 200 comprising two symmetrically arranged scissor heads 2, which are detachably connected to their corresponding scissor clamps 1. Some scissor head assemblies 200 have straight blades, while others have curved blades. Other blade shapes are also possible, such as rectangular or triangular notches. This interchangeable scissor head assembly 200 allows the scissors clamps to have blades 20 of different shapes and sizes, adapting to different sample collection environments.

[0031] like Figure 1 As shown, a reset elastic element 3 is provided between the two shearing clamp pieces 1, allowing them to close and open. The reset elastic element 3 is a spring with its two ends connected to the two shearing clamp pieces 1 respectively; of course, it can also be a spring sheet, tension spring, or other parts. Figure 3 As shown: when the reset elastic element 3 is in its natural state, the two shearing parts 1 are in their initial state, as shown in P1 in the figure; when the reset elastic element 3 is in its compressed state, the two shearing parts 1 are in their closed state, as shown in P2 in the figure; when the reset elastic element 3 is in its stretched state, the two shearing parts 1 are in their unfolded state, as shown in P3 in the figure. This allows the two shearing parts 1 to not only close and return to their original state, but also to unfold from their initial state to their unfolded state.

[0032] As a preferred structure in this embodiment, such as Figure 4As shown, a locking structure 4 is provided between the clipper head 2 and the pliers 1 to fix the former to the latter, and an unlocking structure 5 is provided between the two pliers 1 to unlock the locking structure 4 when both are in the unfolded state. Specifically, the pliers 1 has a mounting hole 11, and the clipper head 2 has a mounting post 21 that can be inserted into the mounting hole 11, allowing the clipper head 2 and the pliers 1 to be detachably connected. The installation connection is completed by inserting the clipper head 2 into the pliers 1. Figure 4 and Figure 5 As shown, a spring clip 41 is connected to the mounting pin 21. The locking structure 4 includes a snap-fit ​​part 42 on the spring clip 41 and a snap-fit ​​groove 12 in the mounting hole 11 that snaps into the snap-fit ​​part 42 to prevent the mounting pin 21 from coming out. The unlocking structure 5 includes an arc-shaped groove 13 on the pliers 1 that communicates with the snap-fit ​​groove 12 and a push rod 14 on the pliers 1 that can be inserted into the arc-shaped groove 13 of another pliers 1. The center of the arc-shaped groove 13 is consistent with the rotation center of the two pliers 1, so that when the two pliers 1 are closed and opened, the push rod 14 of the pliers 1 slides in the arc-shaped groove 13 of the other push rod 14. When the two pliers 1 are in the unfolded state, the push rod 14 reaches the snap-fit ​​groove 12 and is used to push out the snap-fit ​​part 42. In normal use of the shears, simply press the two shearing parts 1 together to change them from the initial state to the closed state, and the shearing function can be realized. Then, the reset elastic element 3 can be used to restore them to the initial state. When the shear head 2 needs to be removed, simply pry open the two shearing parts 1 to change them from the initial state to the open state. At this time, the push rod 14 slides in the arc groove 13 to the locking groove 12 and pushes the locking part 42 out of the locking groove 12, so that the shear head 2 can be removed. Its structure is stable and firm and easy to disassemble.

[0033] As a preferred option, such as Figures 1 to 4 As shown, in order to visually identify the approximate size of the sampled block during the sampling process, the shear head 2 is provided with a shear blade 20, and the shear head 2 is also provided with a scale 22 arranged along the shear blade 20.

[0034] Preferably, to prevent cross-contamination between microbial products and samples, the cutting forceps often require heat sterilization after use. Therefore, in this embodiment, the surface of the cutting head 2 is provided with a thermochromic coating, allowing the user to more intuitively observe whether the heating is sufficient during the process. Furthermore, the heated cutting forceps, due to their high temperature, cannot be used directly for sampling, as this would disinfect any existing microorganisms in the sample. Therefore, cooling is required before sampling again. The thermochromic coating facilitates user observation of whether the cutting forceps have reached the low-temperature standard for reuse. The thermochromic coating is preferably a multilayer interference film of metal oxides, such as a spacecraft thermal control coating like SiO2 / Ta2O5 multilayer films. Alternatively, metal oxide coatings such as vanadium dioxide or tungsten oxide (WO3) can also be used.

[0035] The above descriptions are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model. These modifications will not affect the effectiveness of the implementation of this utility model or the practicality of the patent. The scope of protection claimed in this application shall be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
