[0024] The abutting side wall 212 is provided with a plurality of arc-shaped grooves 2121, and the width of each arc-shaped groove 2121 is equal to the cutting width of a single test block 51.
[0025] The step part 21 is symmetrically provided with an abutting side wall 213 on both sides for abutting the material block 5 located on both sides.
[0026] The width of the arc-shaped groove 2121 is equal to the cutting width of a single test block 51.
[0027] With the above structure, the material block 5 needs to be cut by a cutting device when cutting the material block 5, and the placement table 2 is placed on the cutting device and cut by the cutting device.
[0028] By setting a step part 21 on the placement table 2, the material block 5 can be clamped to the step part 21 of the placement table 2, and the front side and the bottom of the material block 5 are sequentially abutted against the abutting side wall 213 and the abutting bottom wall 211 of the step part 21, respectively. By equally dividing the step part 21 into a plurality of test block 51 placement positions, and setting the abutting bottom wall 211 and the abutting side wall 212 on the placement positions, it is beneficial to cut the material block 5 into a plurality of test blocks 51, and the cutting speed is fast, which greatly improves the cutting efficiency.
