A two-section tool joint comprises a first rod, an engaging element, a second rod and a limiting element. The two-section tool joint utilizes an elastic engaging structure to obtain an engaging effect during a multi-angle screwing/unscrewing operation, meanwhile, the tool joint can be fixed stably, avoiding the retraction of the tool joint and reducing the difficultly and inconvenience of the screwing/unscrewing operation.
