By moving the lever 24 towards the center, the snap-fit ​​blocks 22 can be moved. After the two snap-fit ​​blocks 22 are inserted into the grooves, the spring force of the spring rod 23 fixes the snap-fit ​​blocks 22 to the fixed plates 25. This fixation of the fixed plates 25 secures control boxes 2 and 3. The structure on the pressure plate 26 is exactly the same as that on the pressure plate 5.

Two fixing rods 18 are fixedly connected to the side wall of the connecting plate 14. Both clamping plates 17 are slidably connected to the two fixing rods 18. Multiple inserts 19 are fixedly connected to the side wall of one clamping plate 17. Multiple notches are opened on the other clamping plate 17. The inserts 19 correspond to the notches one by one.

Then, the locking plate 26 is placed over both ends of the composite material body, and the insert block 27 is inserted into the recess. Finally, the locking block 28 locks the composite material body in place. On control box 12, place control box 23 on top of the synthetic material body and pour gravel into control box 23. Then cover it with cover plate 212 and start the electric hydraulic device 19 to press the lower pressure plate 10 against cover plate 212. This will perform a direct shear test on the synthetic material body through pressure. After the test is completed, remove control box 23.
