[0017] See also Figure 1-Figure 2The utility model provides a technical solution: a DNA testing test tube rack, comprising a test tube rack body 1, a placement groove 11 is provided on the upper surface of the test tube rack body 1, a limited position block 12 is movably connected to the inner side of the placement groove 11, a slide groove 14 is horizontally provided in the middle of the test tube rack body 1, connecting grooves 15 are horizontally symmetrically provided on the inner walls on both sides of the slide groove 14, a connecting strip 17 is horizontally provided on the inner side of the connecting groove 15, one end of the limited position block 12 is placed on the inner side of the connecting groove 15 and is fixedly connected to the outer side of the connecting strip 17, a slider 2 is slidably connected to the inside of the slide groove 14, the connecting strip 17 is fixedly connected to the outer side of the slider 2, a threaded groove 21 is horizontally penetrated inside the slider 2, and screws 22 are rotatably connected to the inner walls on both sides of the slide groove 14 through bearings, and the screws 22 are threadedly connected to the threaded groove 21.

[0018] In this technical solution, the test tube can be positioned by the placement grooves 11 evenly opened on the upper surface of the test tube rack body 1. The slider 2 is slidably connected to the slide groove 14, and the screw 22 is rotated to drive the slider 2 to move left and right in the slide groove 14. When the slider 2 moves to the right, it can drive the connecting bar 17 to move right in the connecting groove 15, thereby pushing one end of the limit block 12 to be inserted into the placement groove 11, and further limiting and clamping the DNA test tube in the placement groove 11, thereby solving the problem of the existing DNA testing test tube rack. During the transportation process of the test tube rack body 1, the DNA test tube is easily dropped from the placement groove 11 and damaged.

[0019] In this embodiment, a clamping groove 13 is formed at one end of the limiting block 12 which is placed inside the placement groove 11 , and a protective pad is bonded to the inner wall of the clamping groove 13 .

[0020] In this technical solution, by opening a clamping groove 13 at one end of the limiting block 12 , the clamping effect of the limiting block 12 on the DNA test tube in the placement groove 11 can be improved.

[0021] In this embodiment, a guide groove 16 is provided on the inner wall of the placement groove 11, and the limit block 12 is slidably connected to the guide groove 16. The placement groove 11 is connected to the connecting groove 15 through the guide groove 16. The size of the connecting groove 15 matches that of the limit block 12. The placement grooves 11 are evenly distributed on the upper surface of the test tube rack body 1, and the size of the limit block 12 matches that of the placement groove 11.

[0022] In this technical solution, when the DNA test tube in the placement slot 11 needs to be taken out, the screw rod 22 is rotated in the opposite direction to drive the slider 2 to move to the left, and the limit block 12 can be pulled into the connecting slot 15 through the connecting bar 17, thereby releasing the squeezing and fixing of the DNA test tube in the placement slot 11, and the DNA test tube in the placement slot 11 can be taken out.

[0023] When a DNA testing tube rack is in use, the placement grooves 11 evenly opened on the upper surface of the test tube rack body 1 can be used to position and support the test tube. The slider 2 is slidably connected to the slide groove 14, and the screw rod 22 is rotated to drive the slider 2 to move left and right in the slide groove 14. When the slider 2 moves to the right, it can drive the connecting bar 17 to move right in the connecting groove 15, thereby pushing one end of the limit block 12 to be inserted into the placement groove 11. The clamping groove 13 opened at one end of the limit block 12 can effectively limit and clamp the DNA test tube in the placement groove 11, thereby solving the problem of the existing DNA testing tube rack that the DNA test tube is easy to fall and be damaged from the placement groove 11 during the transportation process of the test tube rack body 1. The screw rod 22 is rotated in the opposite direction to drive the slider 2 to move left, and the limit block 12 can be pulled into the connecting groove 15 through the connecting bar 17, thereby releasing the squeezing and fixing of the DNA test tube in the placement groove 11, and the DNA test tube in the placement groove 11 can be taken out.
