Description

Technical Field

[0001] The utility model relates to the technical field of Arabidopsis thaliana, in particular to a device for collecting Arabidopsis thaliana. Background Technique

[0002] Arabidopsis thaliana is an annual slender herb of the cruciferous family and genus, often used as a model plant to screen mutants, and is a very important model organism in plant molecular genetics and breeding research. The fruit of Arabidopsis thaliana is a silique, and the fruit pod is prone to cracking in the later stage of maturity, and the seeds are easy to eject into the external environment. It is extremely difficult to collect the seeds in the later stage of maturity and is limited by the collection tools. When the operation is improper or there is a slight vibration, the silique is easy to crack, resulting in seed ejection loss.

[0003] The current tools used for collecting Arabidopsis thaliana seeds are mainly scissors and tweezers. During the collection process, the pedicel of the Arabidopsis thaliana fruit pod needs to be cut under the condition of being fixed by tweezers. During this process, it is necessary to prevent hand shaking, prevent the vibration of the cut pedicel, and promptly use tweezers to clamp the pedicel. This process requires extremely high concentration of attention, otherwise it will cause the fruit pod to crack and seed loss, and the collection process is relatively cumbersome. For this reason, we propose a device for collecting Arabidopsis thaliana to solve the above problems. Summary of the Utility Model

[0004] In view of the deficiencies of the prior art, the utility model provides a device for collecting Arabidopsis thaliana, which solves the problems that the current tools used for collecting Arabidopsis thaliana seeds are mainly scissors and tweezers. During the collection process, the pedicel of the Arabidopsis thaliana fruit pod needs to be cut under the condition of being fixed by tweezers. During this process, it is necessary to prevent hand shaking, the vibration of the pedicel, and promptly clamp the pedicel when cutting the pedicel. This process requires extremely high concentration of attention, otherwise it is easy to cause the fruit pod to crack and seed loss, and the collection process is relatively cumbersome.

[0005] To achieve the above objectives, the utility model is realized through the following technical solutions: A device for collecting Arabidopsis thaliana includes a static blade assembly. A moving blade assembly is provided at the top of the static blade assembly. A fixing bolt is movably connected to the inner cavities of the moving blade assembly and the static blade assembly through a bearing. A first pair of tweezers is fixedly connected to the left side of the static blade assembly. A fixing mechanism is provided at the bottom of the first pair of tweezers;

[0006] The fixing mechanism includes a limit box. Both the front and rear sides of the bottom of the limit box are fixedly connected with support plates. Both the front and rear sides of the bottom of the limit box are fixedly connected with rotating shafts. A limit plate is movably sleeved on the surface of the rotating shaft. A support spring is fixedly provided on the right side of the support plate. The left side of the limit plate is fixedly connected to the right side of the support spring. A fixing block is slidably connected to the inner cavity of the limit box. A connecting rod is fixedly connected to the bottom of the fixing block. A collector assembly is fixedly connected to the bottom of the connecting rod.

[0013] The utility model provides a device for collecting Arabidopsis thaliana. Compared with the prior art, the following beneficial effects are achieved:

[0014] The utility model is used for collecting Arabidopsis thaliana. By pushing the fixing block into the limiting box, the connecting rod pushes the limiting plate to rotate leftward. When the connecting rod is located in the inner cavity of the limiting box, the supporting spring pushes the limiting plate to reset, completing the limitation of the connecting rod, making the connecting rod fixed, and completing the installation of the collector assembly. The horizontal lines of the vertices of the second blade and the first blade need to be slightly higher than the horizontal lines of the first silica gel pad and the second silica gel pad. This design can make the cut Arabidopsis thaliana fruit stalks be firmly fixed by the first silica gel pad and the second silica gel pad in the stationary blade assembly and the moving blade assembly at the moment of fracture. The material is designed to be soft, which can not only prevent the fruit stalk from shaking during the cutting process, but also prevent the fruit stalk from sliding, so as to ensure that the fruit pod remains stationary after fracture, thereby preventing the fruit pod from cracking and the seeds from ejecting. Through the integrated design of the second tweezer, the first tweezer, the moving blade assembly, the stationary blade assembly and the collector assembly, it is more convenient and fast when collecting seeds. By setting the second tweezer and the first tweezer, the Arabidopsis thaliana fruit pod stalk can be fixed to prevent the seeds from falling after cutting the Arabidopsis thaliana fruit pod stalk, reducing the collection difficulty and the seed loss rate.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-4 , the present utility model provides two technical solutions, specifically including the following embodiments: Embodiment 1

A first tweezer 8 is fixedly connected to the left side of the stationary blade assembly 1. A fixing mechanism 9 is provided at the bottom of the first tweezer 8;

[0023] The fixing mechanism 9 includes a limit box 903. Both the front and rear sides of the bottom of the limit box 903 are fixedly connected with support plates 907. Both the front and rear sides of the bottom of the limit box 903 are fixedly connected with rotating shafts 904. A limit plate 905 is movably sleeved on the surface of the rotating shaft 904. A support spring 906 is fixedly provided on the right side of the support plate 907. The left side of the limit plate 905 is fixedly connected with the right side of the support spring 906. A fixed block 901 is slidably connected to the inner cavity of the limit box 903. A connecting rod 902 is fixedly connected to the bottom of the fixed block 901. A collector assembly 6 is fixedly connected to the bottom of the connecting rod 902;

[0024] By pushing the fixed block 901 into the inside of the limit box 903, the connecting rod 902 pushes the limit plate 905 to rotate leftward. When the connecting rod 902 is located in the inner cavity of the limit box 903, the support spring 906 pushes the limit plate 905 to reset, completing the limitation of the connecting rod 902, making the connecting rod 902 fixed, and making the collector assembly 6 fixedly connected to the bottom of the connecting rod 902 fixed, completing the installation of the collector assembly 6. Among them, the horizontal lines of the vertices of the second blade 103 and the first blade 303 need to be slightly higher than the horizontal lines of the first silica gel pad 302 and the second silica gel pad 102. This design can make the cut Arabidopsis thaliana fruit stalk be firmly fixed by the first silica gel pad 302 and the second silica gel pad 102 of the static blade assembly 1 and the moving blade assembly 3 at the moment of fracture. The material is designed to be soft, which can not only prevent the fruit stalk from shaking during the cutting process, but also prevent the fruit stalk from sliding, so as to ensure that the fruit pod remains stationary after fracture, thereby preventing the fruit pod from cracking and seed ejection. Through the integrated design of the second tweezer 7, the first tweezer 8, the moving blade assembly 3, the static blade assembly 1 and the collector assembly 6, it is more convenient and fast to collect seeds. The static blade assembly 1 can be disassembled from the collector assembly 6 and form a separate instrument. The arc scissors can be used alone when timely collection is not required.

[0025] The surface of the connecting rod 902 is slidably connected to the inner cavity of the limit box 903;

[0026] Through the sliding connection between the surface of the connecting rod 902 and the inner cavity of the limit box 903, the support spring 906 can push the limit plate 905 to reset, complete the limitation of the connecting rod 902, make the collector assembly 6 fixedly connected to the bottom of the connecting rod 902 fixed, and facilitate the fixation of the collector assembly 6.

[0027] The second tweezer 7 is fixedly connected to the left side of the moving blade assembly 3;

[0028] By setting the second tweezer 7, the Arabidopsis thaliana fruit pod stalk can be fixed, preventing the seeds from falling after cutting the Arabidopsis thaliana fruit pod stalk, and greatly reducing the collection difficulty and seed loss rate.

[0029] At the same time, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art. Embodiment 2

[0030] On the basis of Embodiment 1, the moving blade assembly 3 includes a first blade back 301, a first silica gel pad 302 is fixedly connected to the bottom of the first blade back 301, and a first blade 303 is fixedly connected to one end of the first blade back 301.

[0031] The static blade assembly 1 includes a second blade back 101, a second silica gel pad 102 is fixedly connected to the bottom of the second blade back 101, and a second blade 103 is fixedly connected to one end of the second blade back 101.

[0032] The first blade 303 is slightly lower than the first silicone pad 302, and a second handle 4 is fixedly connected to the right side of the moving blade assembly 3.

[0033] The second blade 103 is slightly higher than the second silicone pad 102, and a first handle 2 is fixedly connected to the right side of the stationary blade assembly 1;

[0034] The horizontal line passing through the vertices of the second blade 103 and the first blade 303 needs to be slightly higher than the horizontal lines of the first silicone pad 302 and the second silicone pad 102. This design enables the cut Arabidopsis thaliana fruit stalk to be firmly fixed by the first silicone pad 302 and the second silicone pad 102 of the stationary blade assembly 1 and the moving blade assembly 3 at the moment of fracture. The soft material design can not only prevent the fruit stalk from shaking during cutting but also prevent the fruit stalk from sliding, thus ensuring that the fruit pod remains stationary after fracture and preventing the fruit pod from cracking and seed ejection.

[0035] During operation, the fixing block 901 is pushed into the interior of the limiting box 903, and the connecting rod 902 pushes the limiting plate 905 to rotate leftward. When the connecting rod 902 is located in the inner cavity of the limiting box 903, the supporting spring 906 pushes the limiting plate 905 to reset, completing the limitation of the connecting rod 902 and fixing the connecting rod 902, thus completing the installation of the collector assembly 6. Among them, the horizontal line passing through the vertices of the second blade 103 and the first blade 303 needs to be slightly higher than the horizontal lines of the first silicone pad 302 and the second silicone pad 102. This design enables the cut Arabidopsis thaliana fruit stalk to be firmly fixed by the first silicone pad 302 and the second silicone pad 102 of the stationary blade assembly 1 and the moving blade assembly 3 at the moment of fracture. The soft material design can not only prevent the fruit stalk from shaking during cutting but also prevent the fruit stalk from sliding, thus ensuring that the fruit pod remains stationary after fracture and preventing the fruit pod from cracking and seed ejection. Through the integrated design of the second tweezer 7, the first tweezer 8, the moving blade assembly 3, the stationary blade assembly 1, and the collector assembly 6, it is more convenient and fast to collect seeds. The stationary blade assembly 1 can be detached from the collector assembly 6 and used independently. The arc-shaped scissors can be used alone when timely collection is not required.
