The invention aims to provide a low-cost high-efficient convenient test tool for an electric steering column assembly. The test tool is characterized in that the electric steering column assembly is placed at a corresponding position of the test tool; a reference block and a clamping mechanism limit up-down movement of the electric steering column assembly; a positioning mechanism limits movementof a shaft pin in the horizontal plane; therefore, the electric steering column assembly is clamped and positioned; and then a first hole position detection mechanism, a second hole position detectionmechanism, a handle detection mechanism, a clamping groove detection mechanism and an end surface detection mechanism detect the qualification degree of corresponding parts respectively, namely, multiple indexes can be detected after one-time clamping and positioning, operation is simple, the relative positions of all the parts can be detected, and the detection precision is further improved. Compared with three-coordinate dotting detection in the prior art, the test tool of the invention is low in cost, high in efficiency and convenient to use.
