[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. 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.

[0026] Please refer to Figure 1 , a test tube holder with an adjustment function in this embodiment includes a plurality of test tube bodies 1, a bearing plate 3 and a mounting plate 2. A plurality of jacks corresponding to the placement grooves are provided on the mounting plate 2; two groups of adjustment components, each group having two, for adjusting the height of the mounting plate 2 are provided on the bearing plate 3. A plurality of equally spaced placement grooves are provided on the bearing plate 3, and a buffer pad is installed inside the placement grooves; the adjustment component includes a sleeve 4, and a sleeve rod 5 is sleeved inside the sleeve 4. A plurality of equally spaced limiting holes are provided between each two sleeve rods 5 in each group; an adjustment mechanism 6 for limiting a single group of sleeve rods 5 is provided between each two groups of adjustment components; a fixing mechanism 7 for fixing the test tube holder is installed on the bearing plate 3.

[0027] In this embodiment, by providing the adjusting mechanism 6, the limit on a single set of sleeve rods 5 can be quickly stopped or the limit thereon can be restored, enabling the operator to quickly and simply adjust the height of the mounting plate 2 to adapt to test tubes of different lengths. By providing the fixing mechanism 7, when using the test tube holder, the test tube holder can be fixed to the tabletop to improve the stability of the test tube holder during use and avoid the problem of the test tube holder tipping over due to impact.

[0028] Please refer to Figure 2 , to adjust the height of the mounting plate 2 to adapt to test tubes of different lengths, the adjusting mechanism 6 in this embodiment includes a mounting frame 601 fixed between two sleeves 4 in each group. A connection box 602 is fixed on the mounting frame 601. Long holes in a number of two are formed in the upper and lower side walls of the inner cavity of the connection box 602. A rotating shaft 603 that penetrates and extends to the opposite ends of the two connection boxes 602 is rotatably connected to the opposite side walls of the inner cavity of the connection box 602 through bearings. A worm 604 is fixed on the outer surface of the rotating shaft 603. A worm gear 605 is threadedly connected to the lower surface of the worm 604. A threaded tube 606 is fixed on the inner peripheral wall of the worm gear 605. Two threaded rods 607 are threadedly connected inside the threaded tube 606. Fixing rings 608 are fixed on the outer surfaces of the two threaded rods 607. Sliders 609 are fixed at the upper and lower ends of each fixing ring 608. The four sliders 609 are respectively located inside the long holes and are slidably connected thereto. Connecting rods 610 are fixed at the opposite ends of the two threaded rods 607. Limit rods 611 that respectively penetrate the connection box 602 and extend into the sleeves 4 are fixed at the opposite ends of the two connecting rods 610. The opposite ends of the two limit rods 611 penetrate the sleeves 4 and extend into the limit holes.

[0029] In this embodiment, first, rotate the rotating shaft 603 through the handle. When the rotating shaft 603 rotates, the two limit rods 611 are driven to move out of the limit holes, so as to stop limiting the sleeve rod 5. Further, by adjusting the height of the mounting plate 2, the height of the mounting plate 2 can be adjusted. When it is necessary to restore the limit on the adjusted mounting plate 2, just rotate the handle in the reverse direction to drive the rotating shaft 603 to rotate in the reverse direction, and the limit rods 611 can be inserted back into the limit holes to restore the limit on the sleeve rod 5.

[0030] Please refer to Figure 3, to prevent the test tube holder from being knocked over, the fixing mechanism 7 in this embodiment includes a fixing frame 701 fixed to the bottom surface of the bearing plate 3 and in an L shape. The lower end of the fixing frame 701 is slidably connected with a sliding rod 702 that penetrates and extends into the interior of the fixing frame 701. A clamping plate 703 is fixed to the upper surface of the sliding rod 702. The upper surface of the clamping plate 703 is attached to the lower surface of the bearing plate 3. Four springs 704 are fixed to the lower surface of the clamping plate 703, and the lower surfaces of the four springs 704 are fixed to the upper surface inside the fixing frame 701 to fix the upper and lower ends of the springs 704 and ensure the stability of the springs 704.

[0031] In this embodiment, when it is necessary to fix the bracket, first pull the sliding rod 702 to drive the clamping plate 703 to squeeze the spring 704, and further clamp the table board with the right end opening of the fixing frame 701. Then release the sliding rod 702, and under the elastic action of the spring 704, drive the top surface of the clamping plate 703 to clamp the bottom surface of the table board.

[0032] The working principle of the above embodiment is as follows:

[0033] When it is necessary to adjust the height of the mounting plate 2 to adapt to test tubes of different lengths, first rotate the handle. The rotation of the handle drives the rotation of the rotating shaft 603. During the rotation of the rotating shaft 603, the worm 604 installed on its outer surface will follow the rotation of the rotating shaft 603. Since the bottom surface of the worm 604 meshes with the worm gear 605, the worm gear 605 will be driven to rotate. During the rotation of the worm gear 605, the threaded tube 606 fixed to it will follow its rotation. During the rotation of the threaded tube 606, the two threaded rods 607 inside it will move. The threaded rods 607 are restricted from rotating with the threaded tube 606 under the limiting action of the slider 609 and the chute. When the threaded tube 606 rotates, since the thread directions on the outer surfaces of the two threaded rods 607 are opposite, the two threaded rods 607 will be driven to move towards the opposite ends, further driving the two limiting rods 611 to move towards the opposite ends, so as to move the limiting rods 611 out of the limiting holes, achieving the purpose of stopping the limiting of the sleeve rod 5. Further, by moving the mounting plate 2 upward, the sleeve rod 5 is driven to extend out of the sleeve 4. When adjusted to an appropriate position, rotate the handle in the reverse direction to drive the rotating shaft 603 to rotate in the reverse direction, and the limiting rods 611 can be inserted back into the limiting holes, realizing the limiting of the adjusted sleeve rod 5.

[0034] When it is necessary to fix the bracket after the adjustment is completed, first pull the sliding rod 702 to drive the clamping plate 703 to squeeze the spring 704, and further clamp the table board with the right end opening of the fixing frame 701. Then release the sliding rod 702, and under the elastic action of the spring 704, drive the top surface of the clamping plate 703 to clamp the bottom surface of the table board.

[0035] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
