The invention relates to a countersunk head rivet hole chamfer adjuster. The countersunk head rivet hole chamfer adjuster comprises a shaft box, a shaft sleeve and a mandrel, one end of the shaft sleeve is inserted into the shaft box, the mandrel is coaxially arranged in the shaft sleeve and is in running fit with the shaft sleeve, the shaft sleeve and the shaft box are in sliding fit in the axis direction of the mandrel, and a limiting piece used for limiting the sliding distance of the shaft sleeve is arranged between the shaft sleeve and the shaft box. The countersunk head rivet hole chamfer adjuster has the advantages that abrasion of the mandrel is reduced, the fit clearance between the mandrel and the shaft sleeve is reduced, shaking of a pistol drill during chamfering is reduced, and the consistency of the chamfering size is guaranteed. 本申请涉及一种沉头铆钉孔倒角调节器，包括轴匣，一端插接于轴匣内的轴套和同轴设置于轴套内且与轴套转动配合的芯轴，轴套与轴匣沿芯轴的轴线方向滑移配合，在轴套和轴匣之间设置有用于对轴套滑移距离进行限制的限位件。本申请具有降低芯轴的磨损，减小芯轴与轴套的配合间隙，进而减小倒角时手枪钻的晃动，保证倒角尺寸的一致的优点。
