Portable felt thickness measuring tool

The invention relates to a portable felt thickness measuring tool. A stand column is fixed at the right end part of a lower part support. A calibrated scale is arranged on the stand column. An upper part support is slidably connected at the upper end part of the stand column. The upper part support and the lower part support are arranged in parallel. A lower slide arm is slidably plugged in the lower part support. An upper slide arm is slidably plugged in the upper support. A lower part tray is fixed at the left end part of the lower slide arm. An upper part scale plate is fixed at the left end part of the upper slide arm. The portable felt thickness measuring tool is simple in structure, easy and convenient to operate and accurate in measurement, and different shapes and different areas of felt thickness can be measured so that application range is wide.
