The utility model discloses a flexible laser denudation pool, which comprises a laser system, a flexible denudation pool and a sample pedestal, the flexible denudation pool is provided with a TPR cover shell, the top of the TPR cover shell is connected with an upper support plate, the periphery of the lower part of the TPR cover shell is connected with a lower fixed flexible ring, a plurality of full-thread screw rods are connected between the upper support plate and the lower fixed flexible ring, and the full-thread screw rods are connected with the sample pedestal. The height of the bottom of the TPR cover shell is adjusted by the full-thread screw through the fixing nut, the bottom of the TPR cover shell is attached and sealed to the surface of a sample, a closed cavity is formed between the TPR cover shell and the sample, and a sample detection part becomes a base of the flexible denudation pool; samples are placed on a sample supporting table arranged on a sample table seat, clamping plates are arranged on the two sides of the sample supporting table, the bottom of the sample supporting table is connected with a rotating motor through a rotating disc, and the bottom of the rotating motor is connected with a lifting air cylinder to control rotation and lifting of the sample supporting table. According to the utility model, the sample where a certain point of the detected sample is located is changed into the substrate of the closed cavity of the laser ablation pool, so that multi-point positioning analysis on the sample is realized.
