[0028] Further, such as Figure 2 - Figure 7 As shown, a pair of fixed columns 21 are fixedly connected to the inner side wall of the test tube rack body 1; a plurality of slots 2 are provided at the bottom of the sliding rack 12; a sliding slot 22 is provided on the side wall of the fixed column 21; a spring 23 is fixedly connected to the inner side wall of the sliding slot 22; a fixing pin 24 is fixedly connected to the end of the spring 23. During operation, after repeatedly pulling and pulling the sliding rack 12, the distance between the sliding rack 12 and the device becomes larger, thereby causing the test tube rack body 1 and the sliding rack 12 to shake. Through the slots 2 provided at the bottom of the sliding rack 12, the spring 23 is normally 23 pushes the fixing pin 24 into the card slot 2 to fix the sliding frame 12. When adjustment is needed, the staff pulls the sliding frame 12 with force, and the ends of the card slot 2 and the fixing pin 24 are arc-shaped. When the sliding frame 12 is pulled with force, the fixing pin 24 will be squeezed into the sliding slot 22, and then the sliding frame 12 can be pulled until the fixing pin 24 is pushed into the card slot 2 again. The sliding frame 12 is effectively fixed by the set fixing device, which reduces the shaking of the equipment and the displacement of the sliding frame 12.

[0029] Further, such as Figure 4 , Figure 5 and Figure 7 As shown, a paddle hole 3 is formed on the side wall of the fixing column 21; a paddle 31 is formed on the side wall of the fixing pin 24; the paddle 31 is fixedly connected to the side wall of the fixing pin 24; the paddle 31 passes through the paddle hole 3 and is fixedly connected to the fixing pin 24.

When used for a long time, it will cause excessive wear of the equipment, thereby resulting in poor fixing effect of the fixing pin 24. Through the set paddle 31, when adjusting the sliding frame 12, the staff can pull the paddle 31 downward to pull the fixing pin 24 out of the card slot 2, and then the position of the sliding frame 12 can be easily adjusted, thereby effectively facilitating the staff to use the equipment, improving the convenience of the equipment, and facilitating the staff to adjust the equipment.

[0030] Further, such as Figure 4 , Figure 5 and Figure 7As shown, a pull rope 4 is provided at the end of the fixing pin 24; the pull rope 4 is fixedly connected to the end of the fixing pin 24; a metal ball 41 is provided at the end of the pull rope 4; the metal ball 41 is fixedly connected to the end of the pull rope 4. During operation, when the sliding frame 12 is pulled out, not only can the fixing pin 24 be pulled downward by pulling the paddle 31, but the metal ball 41 can also be held and pulled. When the metal ball 41 is pulled, the fixing pin 24 will be pulled into the sliding groove 22, and then the sliding frame 12 can be pulled. By using a variety of ways to pull the fixing pin 24, when one way is damaged, another way can be used, thereby facilitating the staff to operate the equipment and increasing the convenience of the equipment.

The sliding frame 12 is effectively fixed by the provided fixing device, which reduces the shaking of the equipment and the displacement of the sliding frame 12. When adjusting the sliding frame 12, since the ends of the card slot 2 and the fixing pin 24 are both arc-shaped, the sliding frame 12 needs to be pulled with force to squeeze the fixing pin 24 into the card slot 2. When used for a long time, it will cause excessive wear of the equipment, thereby resulting in poor fixing effect of the fixing pin 24. By providing the paddle 31, when adjusting the sliding frame When the slide rack 12 is pulled out, the staff can swing the paddle 31 downward to pull the fixing pin 24 out of the card slot 2, and then the position of the slide rack 12 can be easily adjusted, which effectively facilitates the staff's use of the equipment, improves the convenience of the equipment, and facilitates the staff's adjustment of the equipment. When the slide rack 12 is pulled out, not only can the fixing pin 24 be pulled downward by paddle 31, but the metal ball 41 can also be held and pulled. When the metal ball 41 is pulled, the fixing pin 24 will be pulled into the sliding slot 22, and then the slide rack 12 can be operated. There are multiple ways to pull the fixing pin 24. When one way is damaged, another way can be used, which makes it easier for the staff to operate the equipment and increases the convenience of the equipment.By setting the first magnet 5 and the second magnet 51, when the test tube rack body 1 does not need to be adjusted, the first magnet 5 and the second magnet 51 will be attracted to each other, thereby fixing the sliding rack 12, thereby improving the stability of the device during adjustment. When the paddles 31 are moved, a pair of paddles 31 need to be moved at the same time, which is inconvenient for the staff to adjust the device. By setting the connecting rod 6, the connecting rod 6 connects the pair of paddles 31 together. When adjusting the device, the pair of paddles 31 can be pulled by pulling the connecting rod 6, so that the staff can pull the connecting rod 6 with one hand and adjust the amount of the sliding rack 12 to be pulled out with the other hand.
