Fastener projection measurement device and fastener projection measurement method

The invention discloses a fastener projection measurement device and a fastener projection measurement method, the fastener projection measurement device comprises a fixed seat, the middle part of the fixed seat is provided with a projection through hole for projection measurement; clamping bodies which can be adjusted in a front-back and left-right sliding mode are installed on the fixing base through an adjusting assembly, and the four clamping bodies clamp the two ends of fasteners with different lengths in projection through holes of the fixing base for projection measurement; therefore, the projection measurement accuracy of the fastener is ensured, and the problem that the projection measurement accuracy of the fastener can not be ensured because the fastener can only be clamped at two points when the length of the fastener is longer or shorter by the existing equipment is solved. 本发明公开了一种紧固件投影测量装置及紧固件投影测量方法，紧固件投影测量装置，包括：固定座，固定座中部有投影测量用的投影通孔；固定座上经调节组件安装有可前后和左右滑动调节的夹持体，四个夹持体将长度不同的紧固件两端夹持在固定座的投影通孔内进行投影测量；
