[0026] The reduction motor 43 is controlled to turn on and drive the transmission gear 2 45 to rotate, and the transmission gear 2 45 drives the transmission gear 1 44 meshing therewith to rotate, thereby driving the rotating shaft 42 to rotate along the inner side of the bearing seat 41, and the rotating shaft 42 drives the turntable 46 to rotate so that the roller 48 rotates along the limiting ring 49, and the turntable 46 drives the water pump arranged above it to rotate at a uniform speed, so that the water pump is located inside the temperature control unit 6 to rotate so that it is heated and cooled evenly, thereby reducing the impact on the test results.

[0027] like Figure 5 As shown, the turntable 46 includes a support platform 461 , and a symmetrically left-right opening of a hollow groove 462 is formed inside the support platform 461 , and a limiting groove 463 is formed on both the left and right sides of the hollow groove 462 .

[0028] By arranging the empty slot 462 and the limiting slot 463 in the support platform 461, when the water pump is located above the support platform 461, the bottom of the water pump is located above the empty slot 462 and remains suspended, so as to ensure uniform heating and cooling.

[0029] The fixing assembly 5 includes a rotating rod 51, which is rotatably connected to the inner side of the empty groove 462.
