Abstract

The invention discloses an electronic flexible rule capable of displaying variable quantity and a measurement method thereof. The electronic flexible rule comprises a flexible rule body, wherein a circuit board is arranged in the flexible rule body and is in circuit connection with a display screen which is arranged on the surface of the flexible rule body. When the display screen is electrified and used for measuring, the current measurement value is recorded and saved; the current measurement value is compared with a target value; and the comparison result can be displayed. The electronic flexible rule is capable of obtaining the current measurement value and comparing the current measurement value with the target value to obtain the comparison result, so that the user can measure the current measurement value and know the variation change; the variable quantity measuring function is added.

Description

technical field [0001] The invention relates to the field of measuring equipment, in particular to an electronic tape measure capable of displaying variation and a measuring method. Background technique [0002] The tape measure is a commonly used measuring tool in people's daily life. Its measuring principle is to set a coil spring box and a ruler tape in the tape measure. There is a scale on the ruler tape. The elastic force will recover the tape. However, the existing tape measure only has this function, especially when it is applied to the measurement of body parts, it cannot record the previous measurement data, nor can it be compared with the previous measurement data, so it is impossible to visually view the change. [0003] Therefore, the prior art still needs to be improved and developed. Contents of the invention [0004] In view of the above-mentioned deficiencies in the prior art, the object of the present invention is to provide an electronic tape measure an...
