[0002] In engineering cost work, an indispensable tool is the tape measure. By pulling out the scale tape, the length data can be measured, which is convenient for calculating the engineering cost. However, as the engineering cost tape measure is used over time, dust will stick to the scale tape on the tape measure. Usually, the scale tape is rolled up in the tape measure shell. The scale tape on the tape measure is long, and it takes a long time for the staff to clean the dust on it, which is inefficient.

When it is put into the shell, it is easy to cause blockage and jamming in the winding and rotating gap, affecting the use of the measuring tape. At the same time, the size of the measuring tape covered with dust and dirt is not clear, which affects the use of the measuring tape. Utility Model Content
