The invention discloses a mechanical structure testing tool of a molded case circuit breaker mechanism. The mechanical structure testing tool comprises a base block and a handle, a fixed rod and a movable rod are arranged at the two ends of the X shaft respectively, the middle of the movable rod and the base block are rotationally installed through a torsional spring, and clamping shafts are vertically arranged at the bottoms of the fixed rod and the movable rod; when the movable rod rotates, the movable rod and the bottom of the fixed rod form a clamping mechanism with an adjustable opening size; the handle is in threaded connection with the top of the base block, a conical sliding block is installed outside the handle in a sliding mode, and a spring is arranged between the sliding block and the handle in the relative movement direction; when the spring is released, the sliding block is pushed to move downwards, the conical surface of the sliding block makes contact with the upper end of the movable rod and
