[0002] A gauge is a special inspection device used to measure and evaluate the size, shape, position, and quality of a part. Dial indicators are precision measuring tools commonly used in machining and quality inspection. They can provide extremely high measurement accuracy and are used to ensure that the size and shape of parts in the manufacturing process meet strict specifications. They are mainly used to detect the shape and position errors of workpieces and perform precision alignment. When using a dial indicator, it needs to be fixed on a bracket to facilitate the use of the dial indicator and ensure accuracy during use.

[0003] The existing dial indicator magnetic bracket adsorbs the magnetic base on the workpiece when in use. However, the surface of the workpiece to be tested is not completely flat, and the magnetic base may not be adsorbed firmly, causing the magnetic base to vibrate and move out of position during measurement. On the one hand, this causes inaccurate measurement, and on the other hand, it may cause the bracket to fall and damage the dial indicator. Utility Model Content
