[0031] When using the assembled concrete strength testing instrument, Figure 1 , Figure 2 ,and Figure 3 As shown, first, the concrete block to be tested is placed on the upper end of the testing platform 1, and then the movable plate 8 is pressed downward to slide between the movable plate 8 and the fixed block 10, and the movable plate 8 squeezes the spring 9, so that the spring 9 is elastically deformed, and the movable plate 8 drives the fixed rod 11 to move downward, so that the fixed rod 11 is disengaged from the movable bracket 6, and then the limit between the movable bracket 6 and the side plate 5 is released, and then the movable bracket 6 is pulled to the side close to the vertical central axis of the testing platform 1, and the movable bracket 6 slides between the side plate 5, and the movable bracket 6 drives the fixed clamping plate 7 to extend and retract at the upper end of the testing platform 1, so that the fixed clamping plate 7 clamps and limits the concrete block at the upper end of the testing platform 1 to prevent the concrete block from shifting during the testing process. After the clamping is completed, the movable plate 8 is directly released, and at this time the spring 9 restores its elastic deformation, driving the movable plate 8 to slide upward, so that the movable plate 8 drives the fixed rod 11 to move upward, so that the fixed rod 11 is engaged with the corresponding position of the lower end of the movable bracket 6, and then the movable bracket 6 and the side plate 5 are limited.

[0032] After the concrete block is positioned, Figure 6As shown, a connecting mechanism 13 is provided at the rear end of the protective cover 12, and the connecting mechanism 13 includes a movable column 14 fixedly connected to the rear end of the protective cover 12, an auxiliary plate 15 fixedly connected to the rear end of the movable column 14, a connecting bolt 16 for connecting and and a limiting block 17 for positioning.

The connecting mechanism 13 drives the protective cover 12 to move downward, so that the protective cover 12 is lifted and lowered at the upper end of the testing platform 1. The protective cover 12 is arranged on the outer side of the concrete block, and then the connecting bolt 16 threadedly connected to the upper end of the auxiliary plate 15 is rotated, so that the connecting bolt 16 drives the limiting block 17 to engage with the fixed bracket 2, thereby facilitating the limiting of the movable column 14 and the fixed bracket 2.

[0033] After the protective cover 12 is limited, the electric telescopic rod 3 installed on the upper end of the fixed bracket 2 is started, and the electric telescopic rod 3 drives the extrusion detection block 4 to move downward to perform extrusion detection on the concrete block, and the extrusion detection block 4 is provided with a corresponding pressure sensor to sense the magnitude of the extrusion force, so that the strength of the concrete block can be detected, and the protective cover 12 is arranged on the outside of the concrete block, which can prevent the concrete block from splashing and collapsing outward during the extrusion detection process to cause harm to the operator, thereby eliminating safety hazards.
