[0024] The test materials 3 are not installed in adjacent dry test blocks 13 at the same time; the test material 3 is cotton cloth or plastic film.

[0025] A first cavity 27 is formed inwardly at one end of the spacing beam 10, and a sliding block 6 is slidably connected in the first cavity 27. One end of a first spring 14 is provided on the inner wall of the first cavity 27, and the other end of the first spring 14 is connected to the sliding block 6. One end of a locking rod 15 is also axially connected to the inner wall of the first cavity 27, and a second spring 16 is installed at the bottom of the other end of the locking rod 15. A limiting tube 22 is provided outside the second spring 16, and a counterweight 23 is connected to the bottom of the second spring 16. The sliding block 6 is formed with a first channel 17 inwardly in cooperation with the locking rod 15, and one end of the first channel 17 is connected with a transverse second channel 18, the horizontal height of the first channel 17 is greater than the horizontal height of the second channel 18, and the second channel 18 is connected with a third channel 19, the third channel 19 is a slope, the horizontal height of the bottom of the slope is less than the second channel 18, and the horizontal height of the top of the slope is not less than the horizontal height of the first channel 17, and the third channel 19 is connected with the other end of the first channel 17, and a limiting groove 21 whose arc matches the limiting tube 22 is formed inwardly on one side of the middle part of the second channel 18, and a guide protrusion 20 is formed in the other side of the middle part of the second channel 18; an elastic rubber strip 28 is installed on one side of the sliding block 6 located inside the first cavity 27, and when the elastic rubber strip 28 is against the inner wall of the first cavity 27 and the elastic rubber strip 28 is not in the ultimate compression state, the limiting tube 22 is located in the limiting groove 21, and when the second spring 16 is located on the first channel, the second spring 16 is in a compressed state.

[0027] Take cotton cloth as an example:

[0028] In the test preparation stage, prepare a cotton cloth of the same size as the block 13 to be tested. When installing the cotton cloth, first lift the slider 24 upward to fit the spacing beam 10, pass one end of the cotton cloth through the guide groove 25, and then push the sliding block 6 into the first cavity 27. Figure 4 As shown, the second spring 16 will start to move in the first channel 17 with the movement of the sliding block 6, until it moves to the end of the first channel 17, the second spring 16 enters the second channel 18, and under the gravity of the counterweight 23, the counterweight 23 contacts the bottom of the second channel 18. After the sliding block 6 is released, the sliding block 6 moves outward under the action of the first spring 14. At this time, the limiting tube 22 sleeved on the outside of the second spring 16 will move to the limiting groove 21 to limit the slider 24. At this time, the elastic rubber strip 28 at the end of the sliding block 6 cooperates with the inner wall of the first cavity 27 to limit the cotton cloth. At this time, the slider 24 is released, and the slider 24 moves to the bottom of the block 13 to be tested under the action of gravity. At the same time, under the action of the guide groove 25, the cotton cloth is almost flat, and the installation of the cotton cloth is completed.

[0029] When the cotton cloth needs to be replaced, the sliding block 6 is pushed into the first cavity 27 again. Figure 4, the limiting tube 22 leaves the limiting groove 21, and at the same time, under the action of the guide protrusion 20, the second spring 16 continues to move in the second channel 18 until it enters the third channel 19. After releasing the sliding block 6, the sliding block 6 moves outward under the action of the first spring 14. At the same time, the second spring 16 returns to the first channel 17 through the slope to complete the reset.

It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
