A slider 65 is slidably connected to the inner wall of the sliding groove 64. The cross-section of the slider 65 is in a "T" shape. A protective shell 66 is fixedly connected to the surface of the slider 65. A threaded column 67 is fixedly connected to the surface of the sliding block 4. A fixing plate 69 is inserted through the arc surface of the threaded column 67. A nut 68 is threadedly connected to the arc surface of the threaded column 67. When the testing machine 1 is used to test the strength of the rock and soil during the process of geotechnical engineering, first place the rock and soil on the surface of the placing table 3, and then rotate the protective covers 63 on both sides of the sliding block 4 to make the mounting plates 62 on the protective covers 63 rotate on the arc surfaces of the rotating shaft plates 61 on the surface of the sliding block 4 until the two protective covers 63 contact each other. Then insert the fixing plate 69 through the arc surface of the threaded column 67 on the surface of the sliding block 4, and then threadedly connect the nut 68 to the threaded column 67 to make the fixing plate 69 contact and press on the surface of the protective cover 63. Then operate the control panel 2 on the testing machine 1 to set and debug the testing machine 1 to make the sliding block 4 slide, and make the slider 65 on the protective shell 66 slide on the inner wall of the sliding groove 64 on the surface of the protective shell 66.

Through the arrangement of the spring 610, after the positions of the two protective shells 66 are fixed, when the protective shell 66 on the arc surface of the protective shell 66 is in use, it can contact the surface of the testing machine 1 more quickly under the action of the force of the spring 610, and further better enable the combined state of the protective shell 66 and the protective cover 63 to protect the rock mass testing machine 1.

Card plates 72 are respectively rotatably connected to the arc surfaces of the two rotating frames 71. A bolt 73 is threadedly connected through the surface of the card plate 72, and the bolt 73 is threadedly connected to the arc surface of the rotating frame 71. A fixing groove 76 is opened on the arc surface of the protective shell 66, and the card plate 72 is clamped with the inner wall of the fixing groove 76. When the protection device 6 is wrapped around the rock mass during the pressure strength test, rotate the card plates 72 on the two rotating frames 71 until the card plates 72 contact and press into the fixing groove 76 on the arc surface of the protective shell 66, then thread the bolt 73 through the surface of the card plate 72 until it penetrates, and finally thread the bolt 73 onto the arc surface of the rotating frame 71 to fix the position of the card plate 72. At this time, when the testing machine 1 is used to test the rock mass, it can better fix and limit the position of the protective shell 66 of the protection device 6, so as to better prevent the extrusion and splashing of rock blocks, and further improve the use effect of the protection device 6.

[0034] Working principle: When the rock and soil are subjected to strength tests using the testing machine 1 during the progress of geotechnical engineering, first place the rock and soil on the surface of the placing table 3, and then rotate the protective covers 63 on both sides of the sliding block 4 so that the mounting plates 62 on the protective covers 63 rotate on the arc surface of the rotating shaft plate 61 on the surface of the sliding block 4 until the two protective covers 63 contact each other. Then insert the fixing plate 69 through and on the arc surface of the threaded post 67 on the surface of the sliding block 4, and then rotate the knob 612 fixedly connected to the nut 68 to threadedly connect the nut 68 to the threaded post 67, so that the fixing plate 69 contacts and presses on the surface of the protective cover 63, and the fixing plate 69 is inserted into the reinforcement groove 611 on the surface of the protective cover 63. Then operate the control panel 2 on the testing machine 1 to set and debug the testing machine 1, so that the sliding block 4 slides, and the slider 65 on the protective shell 66 slides on the inner wall of the chute 64 on the surface of the protective shell 66. During this process, the pressing block 5 will contact and press the rock mass on the placing table 3. According to the applied pressure, observe the state of the rock and soil. At this time, when the testing machine 1 is performing strength tests on the rock and soil, it can better prevent the rock and soil from splashing debris when being contact-extruded, causing harm to the surrounding staff, and at the same time facilitating the cleaning of the rock and soil after the test, improving the use effect and working efficiency of the testing machine 1.

[0035] When the protective device 6 is wrapped around the rock mass in the pressure strength test, rotate the clamping plates 72 on the two rotating frames 71 until the clamping plates 72 contact and press into the fixing groove 76 on the arc surface of the protective shell 66. Then threadedly connect the bolt 73 sleeved with the washer 74 to the surface of the clamping plate 72 until it penetrates, and finally threadedly connect the bolt 73 to the arc surface of the rotating frame 71 to fix the position of the clamping plate 72. At this time, when the testing machine 1 is used to test the rock mass, it can better fix and limit the position of the protective shell 66 of the protective device 6, thereby better preventing the extrusion and splashing of rock fragments and further improving the use effect of the protective device 6.
