The invention relates to a petroleum drilling coring tool, in particular to a full-adaptation stratum rock core cylinder feeding abnormity display mechanism. A safety joint of the abnormity display mechanism is connected with a mandrel through a hanging bearing in a hanging way; a hanging sleeve sheaths the mandrel; a standby cap and a spring pretensioning press cap are connected with the upper end of the hanging sleeve; a connecting sleeve is suspended on an outer wall step arranged at the lower end of the hanging sleeve; a spring sheaths the hanging sleeve; the upper end of the spring props the lower end of the spring pretensioning press cap; the lower end of the spring props the upper end of the connecting sleeve; the lower end of the connecting sleeve is connected with a throttling sleeve; and a gap between the hanging sleeve and the throttling sleeve is a throttling sleeve ascending position limiting space; and the throttling sleeve sheaths the mandrel. The full-adaptation stratum rock core cylinder feeding abnormity display mechanism has the advantages that the occurrence of rock core cylinder feeding abnormity conditions such as rock core blockage and clamping and crushed rock core repeated cutting can be intuitively displayed under various stratum conditions; the rock core cylinder feeding abnormity can be displayed without the help of other external equipment; and the occurrence of other accidents such as rock core abrasion, geological data loss and coring tool damage can be effectively prevented.
