[0030] The fixing mechanism 7 includes a fixing block 701 fixed to the top of the storage rack 9. A locking block 705 is slidably disposed inside the fixing block 701. The locking block 705 is inserted into the slot 6 opened in the inner wall of the box 1. A spring 702 is fixedly connected to the other end of the locking block 705. The other end of the spring 702 abuts against the side of the fixing block 701 away from the locking block 705. The spring 702 can provide a continuous elastic thrust to the locking block 705, ensuring that the locking block 705 is stably locked in the slot 6, thereby improving the firmness of the connection.

[0031] The fixing mechanism 7 also includes a connecting rod 703. The connecting rod 703 is fixedly connected to two locking blocks 705 in each fixing mechanism 7 through connecting blocks 704 fixed at both ends. The connecting rod 703 enables synchronous linkage of the locking blocks 705 in the two fixing mechanisms 7, allowing the operator to complete the separation or docking of all locking blocks 705 with the slot 6 with only one operation, simplifying the operation steps and improving the disassembly and assembly efficiency.

[0032] The beneficial effects achieved in this embodiment 1 are as follows: Through the coordinated operation of the components of the fixing mechanism 7, under normal conditions, the spring force of the spring 702 pushes the locking block 705 into the slot 6, achieving a stable connection between the storage rack 9 and the box 1, effectively resisting the bumps and impacts during desert transportation and preventing the storage rack 9 from loosening or shifting; during disassembly, pulling the connecting rod 703 can simultaneously disengage all locking blocks 705 from the slot 6, achieving quick assembly and disassembly of the storage rack 9 without the need for any tools. Compared with the existing fixed connection method, the storage rack 9 can be removed as a whole to enable batch retrieval and placement of sample tubes, greatly improving the efficiency of laboratory retrieval.
