Description

technical field [0001] The invention relates to an electric fast measuring digital display micrometer, which belongs to the field of mechanical instrument measurement. Background technique [0002] The current digital display micrometer includes a ruler body, an upper cover, a lower cover, a liquid crystal screen, a measuring rod, a measuring head, a large ratchet, a small ratchet, buttons, pole pieces, PCB boards, locking wheels, batteries, etc. After the LCD screen is embedded in the upper cover, install the PCB board and fix it with screws, then install the cover on the ruler body, install the measuring rod on the ruler body, and then install the large and small ratchets to lock it. The displacement is generated by the linear movement of the measuring rod. A voltage signal is generated, and a digital signal is generated through MCU data processing to generate a digital display on the LCD screen. The current digital display micrometer needs to twist the large and small ra...
