The two second screws (15) drive the two connecting rods through threads, thereby driving the two push blocks (18) to move synchronously towards each other, thereby adjusting the height of the lifting platform (19) until the water level in the water tank (8) exceeds the height of the sample; S3: starting the first motor (13) to drive the first screw rod (12) to rotate, and the first screw rod (12) drives the plurality of beams (901) to move simultaneously, driving the second clamping block (903) and the third clamping block (904) to slide in the direction of the incubation tube until the pressure sensor feeds back a suitable pressure value, stopping the first motor (13), and selecting different pressure values ​​according to the material of the incubation tube; S4: The plurality of electric heating modules (21) are started to work through the control terminal (2), and the heat is transferred to the water in the water tank (8) through the support platform (1902). Through multi-point heating, the water in the water tank (8) is heated evenly, thereby evenly heating the incubation cylinder.
