Description

Technical Field

[0001] This utility model relates to the field of specimen preparation technology, and more specifically to a herbarium specimen fixator. Background Technology

[0002] Herbarium specimens, also known as pressed specimens, are a type of dried plant specimen. They are made by collecting a section of a leafy branch with flowers or fruits, or a whole plant with flowers or fruits, pressing it flat in a specimen press, drying it, and then mounting it on mounting paper. These specimens are used for plant taxonomy research.

[0003] According to announcement number CN209737504U, published on December 6, 2019, a manual nail gun for plastic steel nail clips is disclosed, including a gun head and a fixed magazine connected to the gun head. The upper surface of the gun head has a nailing hole that penetrates it. The fixed magazine has a nailing groove that communicates with the nailing hole. A movable magazine that matches the fixed magazine is installed in the nailing groove. A spring, a push rod, and a push head are installed in the movable magazine. A baffle is provided at the outer end of the movable magazine. One end of the spring abuts against the baffle, and the other end abuts against the push rod. The push rod matches a striker corresponding to the push head. The push head is located in the nailing groove and slides back and forth in the nailing groove. A strip-shaped notch that communicates with the nailing groove is provided below it. Several nail-holding devices are provided in a longitudinally evenly distributed manner in the nailing hole.

[0004] However, since the specimen needs to maintain the integrity of the plant's morphology, traditional nail guns usually require the user to fix the specimen by hand and then use the nail gun to fix the plant's stem. If the nail is nailed crookedly and then removed, it will damage the specimen. Utility Model Content

[0005] The purpose of this invention is to provide a herbarium specimen fixator to solve the above-mentioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a herbarium specimen fixer, including a nail gun and a wrench rotatably mounted thereon, including a trigger hammer movably mounted inside the nail gun, a stop block fixedly mounted at its second end, and a trigger position that forms a blocking engagement with the end of the wrench during the moving stroke of the stop block;

[0007] The guide groove at the first end of the trigger hammer is divided into arc groove and straight groove according to its shape;

[0008] A symmetrically slidably mounted positioning rod on the nail gun, used to fix the specimen, slides with the guide groove to allow the stop block to rotate to the trigger position.

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] like Figure 1-5 As shown, a herbarium specimen fixer includes a nail gun 1 and a wrench 2 rotatably mounted thereon, and a trigger hammer 4 movably mounted inside the nail gun 1, with a stop block 8 fixedly mounted at its second end, and a trigger position that forms a blocking engagement with the end of the wrench 2 during the movement stroke of the stop block 8.

[0025] The guide groove opened at the first end of the trigger hammer 4 is divided into an arc groove 41 and a straight groove 42 according to its shape.

[0026] The positioning rod 3, which is symmetrically and slidably mounted on the nail gun 1 and used to fix the specimen, slides with the guide groove to make the stop block 8 rotate to the trigger position.

[0027] Specifically, it also includes a first spring 6 installed inside the nail gun 1 to drive the trigger hammer 4. A second spring 5 is installed inside the nail gun 1 to hold the positioning rod 3 in a predetermined position. The trigger hammer 4 rotates and slides inside the nail gun 1. When using the nail gun 1 to fix the specimen, the symmetrically arranged positioning rod 3 supports the flat leaves or flowers located on both sides of the petiole, fixing the position of the leaves or flowers. It is observed whether the petiole to be fixed is located in the center of the positioning rod 3. If the position of the petiole is significantly off-center, it is adjusted so that the petiole is in the center of the positioning rod 3. Then, the nail gun 1 is pressed down in a direction perpendicular to the plane of the specimen. At this time, the second spring 5 contracts, and the nail gun 1 is pressed tightly against the specimen. When the positioning rod 3 slides relative to the trigger hammer 4, because the elastic force of the first spring 6 on the trigger hammer 4 is large, the pressure on the trigger hammer 4 from the positioning rod 3 is less than the elastic force of the first spring 6, resulting in a smaller axial displacement of the trigger hammer 4. Furthermore, the positioning rod 3 is guided by the arc groove 41, making the trigger hammer 4... The hammer 4 rotates first, causing the stop block 8 to rotate from the side away from the wrench 2 to the side facing the wrench 2, i.e., the trigger position. Then, the wrench 2 is pressed, causing the end of the wrench 2 to rotate and be blocked by the stop block 8 located under the trigger position. The pressure of the end of the wrench 2 on the stop block 8 overcomes the elastic force of the first spring 6 on the trigger hammer 4, causing the first spring 6 to contract and store force. The end of the wrench 2 drives the trigger hammer 4 to move axially by supporting the stop block 8. At this time, the positioning rod 3 slides with the straight groove 42 and does not interfere with the axial sliding of the trigger hammer 4. After the wrench 2 rotates to a certain angle, its end disengages from the stop block 8. The elastic force of the first spring 6 releases the fixing nail to the blade and fixes the blade. After the firing is completed, the stop block 8 returns to the trigger position, and then the nail gun 1 moves away from the specimen. The positioning rod 3 slides and extends a distance from the nail gun 1 under the deformation recovery action of the second spring 5, and drives the trigger hammer 4 to rotate in the opposite direction again. At this time, the stop block 8 returns to the side away from the wrench 2.

[0028] In the above technology, the symmetrically arranged positioning rods 3 are supported on the flat leaves or flowers located on both sides of the petiole, so that the position of the leaves or flowers is fixed. It is observed whether the petiole that needs to be fixed is located in the center of the positioning rods 3. When the nail gun 1 is close to the specimen, the positioning rods 3 slide with the arc groove 41, and the stop block 8 rotates to the trigger position to avoid firing the fixing nail when the nail gun 1 is not close to the specimen.

[0029] As a further embodiment of this utility model, it also includes a feeding groove 7 mounted on the nail gun 1, and the feeding groove 7 is provided with a nail outlet, which is located in the middle of the two positioning rods 3.

[0030] Specifically, the feeding groove 7 is used to assemble the fixing nails. By observing the center position of the two positioning rods 3, the nail exit position can be predicted, thus avoiding accidental nailing that could damage the specimen.

[0031] As a further embodiment of this utility model, the observation cavity opened on the nail gun 1 has a bottom slope of its inner wall, and a first reflector 13 is fixedly installed on the slope. A second reflector 10 parallel to the first reflector 13 is fixedly installed on the top of the inner wall of the observation cavity.

[0032] Specifically, the observation chamber also includes a convex mirror 11 fixedly mounted on the nail gun 1, with the axis of the convex mirror 11 parallel to the user's line of sight. As the nail gun 1 approaches the specimen, the specimen is reflected by the first reflecting mirror 10 and the second reflecting mirror 13, and then magnified by the convex mirror 11 for better observation by the user. The direction of light reflection is as follows: Figure 5 As indicated by the arrow, to avoid obstructing the view of the nail gun 1 body, the user can observe the unsupported parts of the specimen through the convex mirror 11, thus avoiding crushing the branches and leaves of the specimen when pressing down on the nail gun 1.

[0033] As another embodiment of this utility model, it also includes a transparent scraper 12 that is slidably disposed on the observation cavity and scrapes along the upper surface of the first reflector 13.

[0034] Specifically, the side wall of the observation chamber is provided with an inclined groove for the transparent scraper 12 to slide. A transmission rod 9 that slides with the transparent scraper 12 is fixed on the positioning rod 3. When the positioning rod 3 slides along the side of the nail gun 1, it drives the transmission rod 9 to slide along the inclined groove, thereby driving the transparent scraper 12 to scrape the upper surface of the first reflector 13. The transparent scraper 12 is made of transparent plastic to avoid affecting the observation of the specimen and to clean the first reflector 13, preventing leaf fragments on the specimen from adhering to the first reflector 13.

[0035] Working principle: When using nail gun 1 to fix the specimen, the symmetrically arranged positioning rods 3 support the flat leaves or flowers located on both sides of the petiole, fixing the position of the leaves or flowers and placing the petiole in the center of the positioning rods 3. Then, the nail gun 1 is pressed down in a direction perpendicular to the plane of the specimen. At this time, the second spring 5 contracts, and the nail gun 1 is pressed tightly against the specimen. When the positioning rods 3 slide relative to the trigger hammer 4, the elastic force of the first spring 6 on the trigger hammer 4 is large, and the pressure on the trigger hammer 4 from the positioning rod 3 is less than the elastic force of the first spring 6. This results in a smaller axial displacement of the trigger hammer 4. Furthermore, the positioning rod 3 is guided by the arc groove 41, causing the trigger hammer 4 to rotate first, and driving the stop block 8 to rotate from the side away from the wrench 2 to the side facing the wrench 2, i.e., the triggering position. Then, press the wrench 2, causing its end to rotate and be blocked by the stop block 8 located below the trigger position. The pressure of the wrench 2 end on the stop block 8 overcomes the elastic force of the first spring 6 on the trigger hammer 4, causing the first spring 6 to contract and store force. The end of the wrench 2, by supporting the stop block 8, drives the trigger hammer 4 to move axially. At this time, the positioning rod 3 slides with the straight groove 42, without interfering with the axial sliding of the trigger hammer 4. After the wrench 2 rotates to a certain angle, its end disengages from the stop block 8. The release of the elastic force of the first spring 6 launches the fixing nail onto the leaf stalk, fixing the leaf stalk. As the nail gun 1 approaches the specimen, the specimen is reflected by the first reflector 10 and the second reflector 13, and then magnified by the convex mirror 11 for better observation by the user. The direction of light reflection is as follows: Figure 5 As indicated by the arrow, to avoid obstructing the view of the nail gun 1 body, the user can observe the unsupported parts of the specimen through the convex mirror 11, avoiding crushing the branches and leaves of the specimen when pressing down the nail gun 1. After firing, the stop block 8 returns to the trigger position, which then moves the nail gun 1 away from the specimen. The positioning rod 3 slides and extends a distance away from the nail gun 1 under the deformation recovery action of the second spring 5, and drives the trigger hammer 4 to rotate in the opposite direction again. At this time, the stop block 8 returns to the side away from the wrench 2.

[0036] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
