The invention discloses an improved loop resistance test clip for a handcart type circuit breaker. The improved loop resistance test clip comprises a fixed plate, a test piece assembly part and a testpiece, wherein a buckle connecting piece is arranged above the fixed plate; the lower part of the fixed plate is connected with the test piece assembly part through a spring; and the test piece is arranged on the test piece assembly part. By using a connecting combination type structure, the loop resistance test work of various types of handcart type circuit breakers is facilitated, the improvedloop resistance test clip is high in universality, convenient to use and easy for retention, the contact, with a conducting rod of the circuit breaker, of a contactor during testing is compact, the preparation of testing data is time-saving and labor-saving, the improved loop resistance test clip is convenient to carry, a contact terminal is unlikely to damage, the problem of loop resistance testing can be solved reliably in testing site and is not limited by objective environments (elements such as a tough finger oxidation layer and touch finger dust), and the work efficiency is greatly improved while the test data is normalized.
