Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of plant artificial pollination auxiliary tools, and in particular to a plant artificial pollination emasculation tweezers. Background Technology
[0002] Emasculation is a crucial and tedious step in artificial hybridization pollination of plants. It involves removing all the anthers from the flower bud before it opens, and tweezers are an essential tool for this process. Conventional pointed tweezers can easily penetrate and open the flower bud, but they cannot cut the filaments; the anthers must be pulled upwards to remove them. Conventional blunt tweezers cannot penetrate or open the flower bud. In practice, pointed tweezers are usually used to open the flower bud, then the filaments are grasped and pulled upwards to remove the anthers. Alternatively, tweezers and scissors can be used alternately to cut the filaments, but this method is inefficient and can easily damage the style.
[0003] To address the aforementioned technical issues, this utility model provides a plant artificial pollination and emasculation tweezers. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0027] Reference Figure 1-2 This utility model provides a plant artificial pollination emasculation forceps, comprising:
[0028] The tweezers body includes a first tweezer arm 1 and a second tweezer arm 2, which are arranged in a V-shape.
[0029] The tip hook 3 has a groove 4 at the end of the first tweezer arm 1, and the tip hook 3 has a plug 5 fixed at the end, which is inserted into the groove 4.
[0030] The shrinking mechanism includes an elastic component and a pulling component. The elastic component is installed in the groove 4, and the pulling component is installed in the middle position of the side wall of the first tweezer arm 1. The pulling component is fixed to the insert block 5 by the pull wire 8.
[0031] The positioning components are provided in two sets on the first tweezer arm 1, and the pulling components are disposed between the two sets of positioning components.
[0032] The first tweezer arm 1 and the second tweezer arm 2 are respectively provided with serrated grooves at their ends that are far apart from each other, and the serrated grooves on the first tweezer arm 1 and the serrated grooves on the second tweezer arm 2 are arranged correspondingly.
[0033] The plant artificial pollination and emasculation forceps are in normal assembly state. The tip hook 3 is inserted into the groove 4 at the end of the first forceps arm 1 through the insert block 5. The elastic component is installed in the groove 4. The pulling component is installed in the middle of the side wall of the first forceps arm 1 and is fixed to the insert block 5 by the pull wire 8. Two sets of positioning components are set on the first forceps arm 1. The pulling component is located between the two sets of positioning components. The first forceps arm 1 and the second forceps arm 2 have a V-shaped structure, and the ends that are far apart from each other have correspondingly arranged serrated grooves.
[0034] During the process of removing male stamens from plants, the user holds the main body of the tweezers and uses the serrated grooves at the ends of the first tweezer arm 1 and the second tweezer arm 2 to clamp the stamens and other parts of the plant that need to be removed through a clamping action. The serrated grooves can cut off the stamens.
[0035] The pointed hook 3 can cut open the corolla of an unopened flower bud, exposing the filaments and stigma. At the same time, the pointed hook 3 can be used to hook multiple filaments between the first tweezer arm 1 and the second tweezer arm 2, and then cut multiple filaments simultaneously through the serrated groove between the first tweezer arm 1 and the second tweezer arm 2.
[0036] Compared to the fixed end hook 3 in the prior art, the present invention arranges a reciprocating end hook 3, thereby improving the flexibility of the device.
[0037] The solution is further optimized so that the elastic component includes a spring 6, which is set in the groove 4, and the two ends of the spring 6 are fixedly connected to the insert block 5 and the bottom wall of the groove 4, respectively.
[0038] Based on factors such as the weight of the tip hook 3 and the friction between the insert 5 and the groove 4, select a suitable spring 6 with appropriate wire diameter, outer diameter, free length, and effective number of coils. For example, if the tip hook 3 is heavy, a spring 6 with a thicker wire diameter and a larger elastic modulus should be selected to ensure sufficient elastic force to push the tip hook 3 back. Assuming the total mass of the tip hook 3 and the insert 5 is 5g, the required elastic force is approximately 0.05N (considering a certain safety factor). A spring 6 with a wire diameter of 0.3mm, an outer diameter of 3mm, a free length of 10mm, and an effective number of 5 coils can be selected. Its elastic modulus can be calculated based on the material and specifications or determined experimentally.
[0039] When installing spring 6, ensure a secure connection between it and the bottom wall of insert 5 and groove 4, and make sure that the axis of spring 6 coincides with the axis of groove 4 as much as possible. This will prevent spring 6 from shifting or jamming during extension and retraction, which could affect the normal operation of end hook 3. The installation error should be controlled within ±0.1mm.
[0040] Further optimization of the scheme: the pulling component includes a pulling wheel 7, a sliding groove is provided on the side wall of the first tweezer arm 1, the pulling wheel 7 is slidably connected in the sliding groove, and one end of the wire 8 is fixed on the pulling wheel 7.
[0041] The pull wheel 7 slides in the groove. By pulling the pull wheel 7, the wire puller 8 is driven, thereby controlling the extension and retraction of the end hook 3.
[0042] The design of the pull wheel 7 makes the operation smoother. Users can easily slide the pull wheel 7 with their fingers to achieve precise control of the end hook 3. The groove guides the pull wheel 7 to ensure that the pulling direction of the wire 8 is accurate.
[0043] The diameter and width of the pull wheel 7 need to be determined based on the comfort of finger operation and the size of the groove. Generally, the diameter can be between 5-8mm and the width is about 3-5mm to ensure that the fingers can easily grip and slide the pull wheel 7. For example, choosing a pull wheel 7 with a diameter of 6mm and a width of 4mm can ensure both ease of operation and accommodate the finger size of most users.
[0044] The width of the groove should be slightly larger than the width of the pull wheel 7 to ensure smooth sliding of the pull wheel 7. At the same time, the groove depth should be sufficient to prevent the pull wheel 7 from slipping out. The groove width can be 0.2-0.5 mm larger than the pull wheel 7 width, and the depth should be approximately 2-3 mm. The surface roughness of the groove should be controlled below Ra1.6 to reduce frictional resistance.
[0045] The diameter and material of the wire 8 need to be selected based on the tensile force and the usage environment. If the maximum tensile force required to pull the tip hook 3 is 0.5N, a stainless steel wire 8 with a diameter of 0.2mm can be selected, as it has high tensile strength and can meet the usage requirements. The surface of the wire 8 should be smooth, free of rust and burrs, to reduce friction in the perforations and grooves.
[0046] The scheme is further optimized by providing a perforation in the first tweezer arm 1, which is connected to the groove 4, and the wire 8 is inserted through the perforation.
[0047] The diameter of the piercing hole should be slightly larger than the diameter of the drawing wire 8 to ensure that the drawing wire 8 can pass through smoothly, while minimizing the gap between the piercing hole and the drawing wire 8 to prevent the drawing wire 8 from wobbling during the pulling process. Generally, the diameter of the piercing hole can be 0.1-0.2mm larger than the diameter of the drawing wire 8. For example, when the diameter of the drawing wire 8 is 0.2mm, the diameter of the piercing hole can be selected as 0.3mm.
[0048] The perforation position should be accurate to ensure that the wire 8 does not collide with other components inside the tweezers arm during the pulling process. The center line of the perforation should coincide with the connection line between the pull wheel 7 and the insertion block 5, and the deviation should be controlled within ±0.1mm.
[0049] The inner wall of the perforation should be smoothed, such as by polishing or chrome plating, to reduce friction between the wire 8 and the inner wall of the perforation and extend the service life of the wire 8. The surface roughness should be controlled below Ra0.8.
[0050] The design is further optimized by including magnets 9 in the positioning component. Two sets of magnets 9 are fixed on the first tweezer arm 1 and the second tweezer arm 2, respectively, with the magnets 9 on the first tweezer arm 1 and the second tweezer arm 2 arranged opposite each other. A pull wheel 7 is positioned between the two magnets 9 on the first tweezer arm 1. Magnets 9 are installed on both sets of tweezer arms with their magnetic poles facing each other, thus generating a small repulsive force. This ensures that the device retains sufficient resilience after repeated compression, improving its service life.
[0051] To further optimize the design, anti-slip textures 10 are provided on the sidewalls of the first tweezer arm 1 and the second tweezer arm 2, respectively.
[0052] In a further optimized design, the ends of the first tweezers arm 1 and the second tweezers arm 2 near the tip hook 3 are both set as flat surfaces, and the inner surface of the tip hook 3 is set as a cutting surface.
[0053] The inner side of the pointed hook 3 is designed as a cutting edge, which, together with the flat end, can achieve a cutting function independently, making it convenient for operation in confined spaces.

Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
