Description

Technical Field

[0001] The utility model belongs to the field of instrument detection, in particular to an instrument rotation fixing device. Background Art

[0002] Instruments and meters are tools or equipment used to detect, measure, observe and calculate various physical quantities, material components and physical parameters. Vacuum leak detectors, pressure gauges, length gauges, microscopes and multipliers are all instruments and meters. Instruments and meters need to be fixed with a fixing device during the detection process. During use, the instruments and meters need to be continuously rotated for comprehensive observation and detection. The State Intellectual Property Office issued an authorization announcement on July 28, 2023, with the patent number CN219434094U: "Instrument and meter rotation fixing device". The patent discloses a device that can rotate the instrument and meter after it is fixed. However, in the device, the instrument and meter can only rotate along the axis of the support column, and the rotation direction is single, which easily leads to limited observation of the instrument and meter. Therefore, we designed an instrument and meter rotation fixing device. Utility Model Content
