Portable floor thickness detector

The utility model relates to the technical field of thickness detection, and discloses a portable floor thickness detector which solves the problems that when a traditional thickness detector detects the thickness of a floor, it is inconvenient for a user to rapidly detect the thickness of the floor, and the detection efficiency is low. A handle is installed on one side of the top end of the box body, a transmission mechanism is installed in the box body, a movable rod is installed at the bottom end of the transmission mechanism, a connecting assembly is installed at the bottom end of the movable rod, L-shaped measuring rods are installed at the bottom end of the connecting assembly, and scales are arranged on one L-shaped measuring rod. Through arrangement of the toothed plate, the push rod, the first gear, the second gear and other components, adjustment of the horizontal position of the movable rod can be realized, namely adjustment of the horizontal position of the L-shaped measuring rod is realized, rapi
