Zusammenfassung:	A simple tester for testing the torsional force of spanner has a hollow casing. A connecting body is pivoted to one end of said casing. The both ends of said connecting body have rectangular sleeve blocks extended out from the sides of casing for testing the spanner. A primary and at least one secondary rods radially pass through the middle part of said connecting body. Their another ends are pressed by the rollers on the slide track which is crewed with a linkage rod. Turning the linkage rod can change the action position of roller on the primary and secondary rods. Its advantages are high accuracy and high fatigue durability.
