[0042] The specimen rotating assembly includes a second motor 3, a driving sprocket 23, a chain 22, a rotating member 21, a transmission rod 20, a transmission sprocket 19, an intermittent drive disk 18, a transmission shaft 17 and a test bench 15. Three specimen slots are provided at the top end of the test bench 15. Both the transmission shaft 17 and the transmission rod 20 are rotatably connected to the bottom plate 16. The test bench 15 and the intermittent drive disk 18 are respectively installed at both ends of the transmission shaft 17. The transmission sprocket 19 and the rotating member 21 are respectively installed at the top end and the bottom end of the transmission rod 20, and the rotating member 21 is drivingly connected to the intermittent drive disk 18.

A sliding groove 33 is provided at the top end of each spoke 29, and the width of the sliding groove 33 is adapted to the diameter of the sliding column 25.

[0043] Three second sector blocks 28 are installed at the top end of the rotating ring 32, and there is an interval of 120 degrees between two adjacent second sector blocks 28. The outer arc of the first sector block 27 is adapted to the inner arc of the second sector block 28.

[0044] In this embodiment, when the test of one of the samples is completed, the test wheel 13 is first lifted, and then the second motor 3 is started.

The transmission sprocket 19 drives the rotating disk 5 to rotate one circle through the transmission rod 20. After the rotating disk 5 rotates, the rotating disk 5 drives the sliding column 5 to rotate through the rotating rod 26. The sliding column 5 slides on the sliding groove 33 on the two adjacent spokes 29, thereby driving the entire rotating ring 32 to rotate 120 degrees. At this time, the rotating column 25 is suspended above the center disk 24, and the outer circle of the first sector block 27 slides with the inner circle of the second sector block 28.

During the test, the height of the test wheel 13 is adjusted to above the sample by the hand-cranked wheel 31, and then the first motor 30 is started. At this time, the first motor 30 drives the driving disk 4 to rotate, and the driving disk 4 drives the sliding seat 11 to make a crank slider movement through the crank 6, and the sliding seat 11 reciprocates. At this time, the test wheel 13 tests the sample. When the test of one of the samples is completed, the test wheel 13 is lifted first, and then the second motor 3 is started. At this time, the second motor 3 drives the driving sprocket 23 to rotate, and the driving sprocket 23 drives the transmission sprocket 19 to rotate through the chain 22, and the transmission sprocket 19 drives the rotating disk 5 to rotate through the transmission rod 20. After the rotating disk 5 rotates for one circle, the rotating disk 5 drives the sliding column 25 to rotate through the rotating rod 26, and the sliding column 25 slides on the sliding groove 33 on the two adjacent spokes 29, thereby driving the entire rotating ring 32 to rotate 120 degrees. At this time, the rotating column 25 is suspended above the central disk 24, and the outer circle of the first sector block 27 slides with the inner circle of the second sector block 28. At this time, the transmission disk 18 is stationary, and the intermittent transmission disk 18 rotates 120 degrees during this process. The intermittent transmission disk 18 drives the test bench 15 to rotate 120 degrees through the transmission shaft 17, thereby realizing the rotation of the sample, so that the new sample to be tested moves to the bottom of the test wheel 13, and the test wheel 13 is lowered to test the next sample.
