[0025] In this embodiment, after the aerated block is placed on the test bench 4, the aerated block can be pre-fixed by rotating the second screw 6 to push the extrusion plate 5 to extrude the aerated block, thereby ensuring the stability of subsequent cutting of the aerated block. At the same time, while the servo motor 2 drives the first screw 3 to rotate and control the movement of the test bench 4, the cutting operation can be completed quickly as the cylinder 7 drives the cutting blade 9 to move up and down, with high efficiency and stable operation, thereby ensuring the flatness of the sample notch and improving the accuracy of the test results.

[0026] Example 2, refer to Figure 2 A performance test device for autoclaved aerated concrete blocks, wherein the top outer wall of a base 1 is fixedly connected to an air pump 10 by bolts, and an air pipe 11 is connected to an air intake port of the air pump 10, and dust hoppers 12 equidistantly distributed are connected to the outer wall of the air pipe 11, and a dust bag 13 is connected to an exhaust port of the air pump 10.

[0027] In this embodiment, the dust generated when cutting the aerated block can be sucked into the dust hopper 12 in the first time to prevent the surrounding environment from being polluted. As the air pump 10 works, the dust can be collected in the dust bag 13 and effectively collected, thereby improving the environmental quality of the test work.

[0028] Reference Figure 1The top outer wall of the base 1 is provided with symmetrically distributed guide rods 14 , and the bottom outer wall of the test bench 4 is slidably connected to the outer wall of the guide rods 14 .
