[0002] In the experimental operations of multiple disciplines such as microbiology, cell, and molecular biology in the field of biological science research, pipettes are essential experimental tools. A pipette is a tool used in a laboratory to accurately transfer a small amount or trace amount of liquid.

[0003] In the existing technology, when operating a pipette, the angle of the pipette tip is usually controlled by hand-holding to achieve the full transfer of the target sample solution. However, when the target sample solution requires the same transfer angle, relying solely on hand-holding operation is prone to angular errors, resulting in inconsistent diffusion speeds of the target sample solution, and it is not precise enough to use.

[0021] Next, in combination with the accompanying drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. 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.

[0022] Referring to Figures 1-4 , an embodiment provided by the present utility model: a gun head support structure convenient for angle adjustment, including a support frame 1. The support frame 1 includes a base and a vertical plate, and the base is fixedly connected to the vertical plate. There are eight adjustment holes 5 provided in the upper part of the support frame 1, and they are evenly arranged in a circumference. A rotating shaft 201 is rotatably connected to the upper part of the support frame 1. The rotating shaft 201 is located inside two sliding rods 702. A control plate 2 is fixedly connected to the front part of the rotating shaft 201. A support seat 6 is fixedly connected to the center of the control plate 2. The support seat 6 is adapted to the clamping block 701. Both the inner sides of the support seat 6 and the clamping block 701 have an adaptation groove adapted to the pipette gun. Two sliding rods 702 are slidably connected to the control plate 2. The number of the sliding rods 702 is two, and they are symmetrically arranged. A control handle 8 is fixedly connected to the front end of the sliding rod 702. A control plate 7 is fixedly connected to the front side of the control handle 8. A clamping block 701 is fixedly connected to the rear side of the control plate 7;

[0023] By driving the control plate 7 through the control handle 8, the control plate 7 drives the clamping block 701 and the sliding rod 702 to move. At this time, the spring 4 is compressed, so that the distance between the clamping block 701 and the support seat 6 becomes larger. Then, the pipette gun is placed between the two. Then, under the elastic force of the spring 4, the clamping block 701 and the support seat 6 are in contact with each other, and the pipette gun is clamped.

[0024] A buffer cylinder 3 is sleeved on the sliding rod 702 and in front of the control plate 2. The buffer cylinder 3 is made of rubber material. A spring 4 is sleeved on the sliding rod 702 and behind the control plate 2. A matching plate 401 is fixedly connected to the rear end of the sliding rod 702. A locking component 9 is provided in the upper part of the support frame 1;

[0025] The locking component 9 includes a connecting plate 902. A plug rod 904 is fixedly connected to the rear part of the connecting plate 902. The number of the plug rods 904 is two, and they are symmetrically arranged. The plug rods 904 pass through the adjustment hole 5 and the matching plate 401. A magnet block 903 is fixedly connected to the center of the connecting plate 902. The magnet block 903 is adsorbed to the upper part of the support frame 1. A locking ring 901 is fixedly connected to the rear of the connecting plate 902.

[0026] When it is necessary to adjust the angle of the pipette tip, the locking ring 901 drives the connecting plate 902, the connecting plate 902 drives the insertion rod 904, the insertion rod 904 moves out from the mating plate 401 and the adjustment hole 5, rotates the adjustment disk 2 to the required angle, and then passes the insertion rod 904 through the adjustment hole 5 and the mating plate 401 again, and uses the magnet block 903 to adsorb with the support frame 1 to complete the fixation.

[0027] Through the provided locking assembly 9, rotating shaft 201, adjustment disk 2, and mating plate 401, the angle of the adjustment disk 2 can be changed, so that the angle of the pipette tip can be changed, ensuring that the diffusion rate of the target sample solution is consistent; the provided control board 7, slide rod 702, spring 4, and clamping block 701 can clamp the pipette, facilitating taking and using, and being applicable to various scenarios.

[0028] Working principle: During use, the control handle 8 drives the control board 7, the control board 7 drives the clamping block 701 and the slide rod 702 to move. At this time, the spring 4 is compressed, increasing the distance between the clamping block 701 and the support base 6. Place the pipette between the two, and then under the elastic force of the spring 4, the clamping block 701 contacts the support base 6 to clamp the pipette; when it is necessary to adjust the angle of the pipette tip, the locking ring 901 drives the connecting plate 902, the connecting plate 902 drives the insertion rod 904, the insertion rod 904 moves out from the mating plate 401 and the adjustment hole 5, rotates the adjustment disk 2 to the required angle, and then passes the insertion rod 904 through the adjustment hole 5 and the mating plate 401 again, and uses the magnet block 903 to adsorb with the support frame 1 to complete the fixation.

[0029] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
