The cooperation between the movable limit blocks of the connecting component enables the second connection port provided on the movable connecting component to be guided by the positioning column to align with the first connection port, which effectively improves the efficiency of detection.

In addition, because the movable connection assembly of the present invention allows the movable limit block to be slidably arranged in the installation space, even the movable limit block with the second connection port is required to perform multiple inspections. In the disassembly and assembly, the positioning post can also be used to drive the movable limit block to slide to align the second connection port with the first connection port, thereby reducing the cumbersome steps of adjustment and alignment during multiple disassembly and assembly.
