Summary:The invention discloses an improved long rod shaft segment length measurement fixture and a measurement method thereof. The improved long rod shaft segment length measurement fixture comprises a rod part ejector pin, an ejector pin sleeve, a handle part ejector pin and dial test indicators. During a measurement process, the rod part ejector pin and the handle part ejector pin are located at two ends of a measured workpiece for positioning the measured workpiece; the ejector pin sleeve sleeves the rod part ejector pin for ensuring the coaxiality between the rod part ejector pin and the handle part ejector pin. According to the improved long rod shaft segment length measurement fixture and the measurement method thereof, through the coaxiality between the rod part ejector pin and the handle part ejector pin, stability of center holes at two ends of the workpiece is ensured, the long rod shaft segment length measurement beat and the measurement precision are effectively improved, and the long rod shaft product p
