[0043] When the experimental device for testing the performance of the anti-ice adhesion coating of this embodiment is in use, first, the staff places the test sample on the positioning frame 11, and then the positioning cylinder 12 works to drive the four groups of connecting rods 14 on the outer wall of the lifting block 13 to move synchronously, and the lifting block 13 drives the positioning slide block 15 to slide along the outer wall of the limiting guide groove 16 through the connecting rod 14, and the positioning slide block 15 slides to drive the positioning block 17 to fit with the outer wall of the test sample, and the four groups of positioning blocks 17 slide synchronously relative to each other to achieve a stable positioning operation of the test sample, thereby avoiding the deviation of the water droplets injected by the injection syringe 10.
