[0021] The two connecting blocks 10 are installed in the limiting grooves on the inner walls of the two sides of the explosion-proof box 1, so that the connecting blocks 10 can only move along the direction of the limiting grooves. At this time, the two connecting blocks 10 are moved in opposite directions or in the same direction by rotating the screw rod 9, and the support blocks 11 connected to the two ends of the screw rod 9 support and fix the screw rod 9, preventing the screw rod 9 from shaking or deviating during rotation. The connecting rod 12 transmits the movement of the connecting block 10 in the limiting groove to the connecting seat 13, so that the connecting seat 13 can move synchronously with the connecting block 10, thereby adjusting the position of the fixing mechanism. When the clamping block 17 contacts the experimental container, the spring 15 exerts its elastic force, so that the clamping block 17 better fits the surface of the object. In addition, the hinge seat 16 is fixed to the outer wall of one side of the telescopic rod 14, which provides a rotating fulcrum for the clamping block 17, so that the clamping block 17 can adjust the angle according to the shape and surface of the object, thereby improving the contact area and fitting degree of the clamping block 17 and the object, and realizing the fixation of pressure vessels of different sizes and shapes, and ensuring the stability of the object in the explosion-proof box 1.

At this time, a filter plate 18 is installed above the water channel 19. When water passes through the filter plate 18, the filter plate 18 can intercept larger particles in the water, thereby playing a role in preliminary filtration.
