The sample clamping mechanism comprises a base, a fixing rod is fixedly connected to the interior of the base, a fixing block is fixedly connected to one side of the fixing rod, a limiting assembly is arranged on one side of the fixing block, a butt joint assembly is arranged at the position, located on one side of the limiting assembly, of one side of the fixing block, and the butt joint assembly is fixedly connected to one side of the fixing rod. And four placing plates are mounted on one side of the fixing block through a butt joint assembly. By the adoption of the structure, when the placing plate needs to be disassembled and assembled, a worker pulls the pulling plate, the pulling plate enables the first spring to move, the first spring enables the inserting rod to move, the inserting rod leaves the inserting block on one side of the placing plate, then the placing plate is moved, the inserting block is separated from the inserting groove in the fixing block, and disassembling can be completed; therefore
