Description

Technical Field

[0001] The utility model relates to the technical field of sampling tools, in particular to an extrusion type sampling pliers used for toast bread. Background Art

[0002] In order to conduct microbial experiments on toast slices, samples of the toast slices are generally taken first. Currently, microbiological laboratories use scissors to cut the samples before conducting experiments. However, this method of cutting samples is time-consuming and cannot maintain the uniformity of the samples, which can indirectly affect the experimental results. Summary of the Invention

[0003] The utility model aims to provide a squeezing type sampling pliers for toast bread, which can realize rapid sampling and maintain sample uniformity, thereby reducing the error of experimental results.

[0004] A kind of extrusion sampling pliers for toast bread, comprising a first handle and a second handle, wherein the first handle is cross-connected with the second handle, an elastic member is connected to one side of the intersection of the first handle and the second handle, one end of the first handle is connected to an extrusion head, and one end of the second handle is connected to a sampling head, and the extrusion head can cooperate with the sampling head for extrusion.

[0005] In the above scheme, the first handle and the second handle are held, and the toast slice is placed between the extrusion head and the sampling head. The elastic member can support the first handle and the second handle so that the height between the extrusion head and the sampling head can be higher than the toast slice. Then, force is applied to the first handle and the second handle so that the extrusion head can pass through the toast slice and squeeze the toast slice out of the sampling head. In addition, multiple samples of the same shape can be taken at the same time. It is very convenient to use, realizes rapid sampling, ensures sample uniformity, and thus can reduce experimental errors.

[0006] Furthermore, the extrusion head includes a clamp head portion and an extrusion portion, and a plurality of the extrusion portions are vertically connected to the clamp head portion.

[0007] In the above solution, the vertically connected extrusion part can more accurately control the depth and position of the sampling, ensuring the consistency of each sampling. The operator can more intuitively see the contact between the extrusion head and the toast slice during extrusion, which facilitates the control of strength and direction.

[0008] Furthermore, the cross-section of the clamp head is circular, and the extrusion portion is cylindrical.

[0009] In the above scheme, the circular cross-section of the clamp head and the cylindrical extrusion part can apply pressure more evenly, reduce local excessive extrusion of the toast slice, and thus reduce damage to the sample; when the cylindrical extrusion part passes through the toast slice, due to its shape characteristics, it can reduce friction, making the extrusion process smoother.

[0010] Furthermore, the cross section of the sampling head is circular, and a plurality of circular through holes are formed on the sampling head.

[0011] In the above scheme, the extrusion part of the extrusion head can pass through the through hole to sample the toast slices. The circular through hole provides a consistent sampling size, ensuring that the size and shape of each sample are the same, thereby improving the consistency of the sample and the accuracy of the experiment.

[0012] Furthermore, the extrusion head and the sampling head are made of stainless steel.

[0013] In the above solution, the stainless steel has a smooth surface and is easy to clean and disinfect, making it suitable for industries such as food processing and biomedicine, thereby ensuring the hygiene and safety of the sampling process. In addition, stainless steel has high strength and hardness and can withstand greater pressure and wear, thereby improving the durability and service life of the tool.

[0014] Furthermore, the first handle and the second handle are rotatably connected via a pin, and the pin is installed at the intersection.

[0015] In the above solution, pins are used as connecting members, which has a simple design, is easy to manufacture and maintain, and makes the operation more flexible, so that the user can adjust the angle of the handle as needed.

[0016] Furthermore, the elastic member is a spring.

[0017] In the above solution, the spring has excellent elasticity and can quickly return to its original shape after the first handle and the second handle are released, which helps to ensure that the extrusion head and the sampling head can quickly return to their initial positions to prepare for the next sampling. The spring can absorb the vibration and impact during the operation of the first handle and the second handle, thereby improving the sampling accuracy and operating comfort.

[0018] The utility model discloses an extrusion-type sampling pliers for toast bread, which has the beneficial effects of enabling rapid sampling and maintaining sample uniformity, thereby reducing the error in experimental results. Holding the first and second handles, a slice of toast bread is placed between the extrusion head and the sampling head. The elastic member can support the first and second handles so that the height between the extrusion head and the sampling head is higher than the toast bread. Then, force is applied to the first and second handles, allowing the extrusion head to pass through the toast bread slice and squeeze the toast bread slice out of the sampling head. Multiple samples of the same shape can be taken simultaneously, making it very convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The extrusion type sampling pliers for toast bread of the present invention will be described in further detail below with reference to specific embodiments and accompanying drawings.

[0022] like Figure 1 As shown, in a preferred embodiment, the present invention provides an extrusion-type sampling pliers for toast bread, comprising a first handle 1 and a second handle 2, wherein the first handle 1 and the second handle 2 are cross-connected. An elastic member 6 is connected to one side of the intersection 3 of the first handle 1 and the second handle 2. An extrusion head 4 is connected to one end of the first handle 1, and a sampling head 5 is connected to one end of the second handle 2. The extrusion head 4 can cooperate with the sampling head 5 for extrusion. Holding the first handle 1 and the second handle 2, a slice of toast bread is placed between the extrusion head 4 and the sampling head 5. The elastic member 6 can support the first handle 1 and the second handle 2 so that the height between the extrusion head 4 and the sampling head 5 is higher than the toast bread. Then, force is applied to the first handle 1 and the second handle 2, so that the extrusion head 4 can pass through the toast bread slice and squeeze the toast bread slice out of the sampling head 5. Multiple samples of the same shape can be taken simultaneously, which is very convenient to use, realizes rapid sampling, ensures sample uniformity, and thus can reduce experimental errors.

[0023] like Figure 1 As shown, in some embodiments, the extrusion head 4 includes a clamp head 41 and an extrusion portion 42, with multiple extrusion portions 42 connected perpendicularly to the clamp head 41. The perpendicularly connected extrusion portions 42 can more accurately control the depth and position of the sample, ensuring consistency in each sample. The operator can more intuitively see the contact between the extrusion head 4 and the toast slice during the extrusion, making it easier to control the force and direction.

[0024] like Figure 1 As shown, in some embodiments, the clamp head 41 has a circular cross-section and the extrusion portion 42 is cylindrical. The circular cross-section of the clamp head 41 and the cylindrical extrusion portion 42 can apply pressure more evenly, reducing localized excessive extrusion of the toast slice, thereby reducing damage to the sample. The cylindrical extrusion portion 42, due to its shape, can reduce friction when passing through the toast slice, making the extrusion process smoother.

[0025] like Figure 1As shown, in some embodiments, the sampling head 5 has a circular cross-section and is provided with a plurality of circular through-holes 51. The extrusion portion 42 of the extrusion head 4 can pass through the through-holes 51 to sample the toast. The circular through-holes 51 provide a consistent sampling size, ensuring that each sample is of the same size and shape, thereby improving sample consistency and experimental accuracy.

[0026] like Figure 1 As shown, in some embodiments, the extrusion head 4 and the sampling head 5 are made of stainless steel. Stainless steel has a smooth surface and is easy to clean and disinfect, making it suitable for industries such as food processing and biomedicine, thereby ensuring the hygienic safety of the sampling process. Stainless steel also has high strength and hardness, can withstand greater pressure and wear, and improves the durability and service life of the tool.

[0027] like Figure 1 As shown, in some embodiments, the first handle 1 and the second handle 2 are rotatably connected by a pin, and the pin is installed at the intersection 3. Using the pin as a connecting member is simple in design, easy to manufacture and maintain, and makes the operation more flexible, so that the user can adjust the angle of the handle as needed.

[0028] like Figure 1 As shown, in some embodiments, the elastic member 6 is a spring. The spring has excellent elasticity and can quickly return to its original position after the first handle 1 and the second handle 2 are released. This helps ensure that the extrusion head 4 and the sampling head 5 can quickly return to their initial positions to prepare for the next sampling. The spring can absorb vibration and impact when the first handle 1 and the second handle 2 are operated, thereby improving sampling accuracy and operating comfort.

[0029] The utility model discloses an extrusion type sampling pliers for toast bread, which has the following working principles and processes: hold the first handle 1 and the second handle 2, and open the extrusion head 4 and the sampling head 5 to a certain extent, so that the height between them can be higher than the toast bread slice; place the toast bread slice between the extrusion head 4 and the sampling head 5; then apply force to the first handle 1 and the second handle 2, so that the extrusion part 42 of the extrusion head 4 can pass through the toast bread slice, and squeeze the toast bread slice out from the through hole 51 of the sampling head 5; finally, put the bread sample into a buffer solution. The extrusion type sampling pliers for toast bread of the present invention are different from the existing stainless steel scissors, and can shorten the sampling time, improve the working efficiency, sample evenly, and are convenient to use.
