In the process of industrial process control and technical measurement, mechanical pressure gauges are increasingly widely used because of their elastic sensitive elements with high mechanical strength and convenient production. However, there are still some problems. When carrying pressure measurement, most existing pressure gauges do not have protective devices, so they may fall when used for a long time, causing damage to the internal parts of the body, resulting in inaccurate data when measuring pressure, greatly reducing the service life of the pressure gauge. Therefore, a pressure gauge with an anti-fall mechanism is urgently needed to solve the above problems.
