[0003] The patent (CN216717190U) discloses a portable manual reading device for tensioning wire and tensioning wire type horizontal displacement meter, comprising two symmetrically arranged support rods and a flat plate bracket movably connected to the upper ends of the two support rods, and the height of the flat plate bracket is adjustable; the flat plate bracket is provided with a laser pen that passes through the flat plate bracket and emits a laser beam downward, and the flat plate bracket is inlaid with a bubble level.
