The bottom end of the spring 241 is fixedly connected to a dial bar 28, and the top of the dial bar 28 is fixedly connected to a long rod 27. The bottom end of the support seat 23 is internally slidably connected to a detection block 25, and the top of the detection block 25 is fixedly connected to a pressure sensor 26. The two sides of the detection block 25 are respectively fixedly connected to the limit bars 251, and the two ends of the support seat 23 are internally slidably connected to the limit rods 291. The two ends of the limit rod 291 are fixedly connected to the limit block 292 respectively. The top of the limit block 292 is fixedly connected to the bottom of the guide seat 21. The front of the guide seat 21 is fixedly connected with a positioning strip 29. The bottom end of one side of the holder 24 is fixedly connected with a grab 242. A through hole is provided in the top inner left end of the holder 24. The surface of the long rod 27 passes through the through hole in the top inner left end of the holder 24. A slide groove is provided inside the guide seat 21. The surface of the T-shaped block 22 is slidably connected to the inside of the slide groove. A slot is provided inside the holder 24. The surface of the shift bar 28 is slidably connected to the inside of the slot. A rectangular cavity is provided inside the support seat 23.

[0030] Furthermore, a positioning hole is provided inside the positioning bar 29, and the surface of the long rod 27 matches the inside of the positioning hole. The shift bar 28 is moved downward to drive the long rod 27 downward to disengage from the position inside the positioning bar 29, so that the T-shaped block 22 can move inside the guide seat 21 and drive the detection block 25 to move, thereby enabling data detection at any position of the concrete sample, thereby obtaining multiple sets of sample data, and correspondingly improving the accuracy of data detection and reducing data detection errors.

[0031] Example 2

[0032] See Figure 1-5On the basis of the first embodiment, the driving mechanism 3 is further obtained to include a support frame 31, the support frame 31 is fixedly connected to the top of the base 1, the top of the support frame 31 is fixedly connected to a hydraulic lifting device 32, the bottom end of the hydraulic lifting device 32 is fixedly connected to a plate 33, the top of the plate 33 is fixedly connected to a motor 34, the surface of the motor 34 is meshed with a main gear rack 35, the surface of the main gear rack 35 is meshed with a sub-gear rack 36, the top of the sub-gear rack 36 is rotatably connected to the inside of the plate 33, the bottom end of the sub-gear rack 36 is fixedly connected to the top of the guide seat 21, sliding holes are respectively provided inside the four ends of the plate 33, and the surface of the support frame 31 is slidably connected to the inside of the sliding holes.

[0033] Furthermore, a cavity is opened inside the flat plate 33, and the surfaces of the main gear rack 35 and the sub-gear rack 36 are both located inside the cavity.

During the detection, the detection block 25 is subjected to pressure to drive the pressure sensor 26 upward, thereby causing the pressure sensor 26 to be squeezed with the top of the support seat 23 and generate pressure, thereby transmitting the data through the pressure sensor 26.

[0034] During actual operation, when this device is used, the pressure sensor 26 is externally connected to a computer data transmission device. When testing the strength of concrete, the concrete sample to be tested is placed on the top of the base 1.

During the test, the detection block 25 is subjected to pressure and drives the pressure sensor 26 upward, thereby causing the pressure sensor 26 to squeeze the top of the support seat 23 and generate pressure, thereby transmitting data through the pressure sensor 26.

[0035] When it is necessary to detect different positions of the concrete sample, the motor 34 rotates to drive the main gear rack 35 and the sub-gear rack 36 to rotate, thereby driving the guide seat 21 to change the position of the detection block 25 when rotating. In addition, the dial bar 28 can be moved downward to drive the long rod 27 downward to disengage from the position inside the positioning bar 29, so that the T-shaped block 22 can move inside the guide seat 21 and drive the detection block 25 to move, thereby allowing data detection at any position of the concrete sample, thereby obtaining multiple sets of sample data, and correspondingly improving the accuracy of data detection and reducing data detection errors.
