The fixing component 4 plays a role in adapting to the water bath ports of different water bath equipment, improving the use efficiency of the test tube rack.

[0021] The fixing assembly 4 includes an auxiliary block 41 fixedly connected to the outer wall of the positioning ring 5. The auxiliary block 41 is fixed to the outer wall of the positioning ring 5, which has the effect of limiting the rotating rod 42 in the horizontal position. The inner wall of the auxiliary block 41 is provided with a rotating rod 42, and the rotating rod 42 is rotated inside the auxiliary block 41 through the support of the rotating shaft. A limiting block 43 is provided in the inner cavity of the rotating rod 42, and a limiting rod 44 drives the limiting block 43 to slide in the inner cavity of the rotating rod 42. A limiting rod 44 is provided at the bottom of the limiting block 43, and a support plate 49 drives the limiting rod 44 to slide inside the rotating rod 42. Multiple groups of limiting grooves 45 are provided on both sides of the limiting rod 44, and the limiting rod 47 is restricted inside the limiting groove 45. A support plate 49 is provided at the bottom of the limiting rod 44. The limiting rod 44 is fixed inside the water bath device through the support of the support plate 49. Two groups of limiting rods 47 are provided inside the rotating rod 42, and the limiting rod 47 rotates inside the rotating groove 48 through the rotating shaft. A spring 46 is provided on the opposite side of the limiting rod 47, and the spring 46 has the effect of resetting the limiting rod 47.

[0022] A sliding groove matching the limiting block 43 is provided inside the rotating rod 42 , and the limiting block 43 is driven to slide in the inner cavity of the rotating rod 42 by the limiting rod 44 .

[0023] The limit block 8 is arranged above the anti-slip rubber pad 7 , the limit block 8 is arranged below the positioning ring 5 , and the limit block 8 is arranged between the anti-slip rubber pad 7 and the positioning ring 5 .
