The invention discloses a novel multipurpose converter test clamp. The test clamp is characterized by comprising a first clamp body (1) and a second clamp body (2) which are hinged with each other; areturn spring (3) is arranged at a hinged joint of the first clamp body (1) and the second clamp body (2); a grounding wire terminal (4) is arranged at the tail end of the first clamp body (1); a first test wire terminal (5) is arranged at the tail end of the second clamp body (2); the grounding wire terminal (4) and the first test wire terminal (5) are respectively connected with the opening partof the first clamp body (1) or the second clamp body (2) through wires. The test clamp provided by the invention can meet the requirements of the test clamp for performing winding deformation test, direct current resistance test, loop resistance test, capacitor capacitance test, and the like, the connection for the test wire can be directly performed on the test clamp and the multifunctional clamp can be realized.
