Clamp connection type audio wire distribution frame fault telephone tester

The present invention relates to a clamp connection type audio wire distribution frame fault telephone tester which comprises a test wire, an alligator clip and a test head. The test wire is connected to the alligator clip. The test head is a conductive wire body. Two ends of the conductive wire body are exposed. The middle outer surface of the conductive wire body is sleeved by an insulation sleeve, and the exposed end of one end of the conductive wire body is connected to the alligator clip. By using the clamp connection type audio wire distribution frame fault telephone tester, a security unit can be tested in an online way without pulling the security unit out, the clamp connection type audio wire distribution frame fault telephone tester is convenient to use, at the same time the tool can be used by inner and outer wires, and the replacement of the tool back and forth is not needed. The transformation cost is almost zero investment, time and labor are saved, the working efficiency is greatly improved, and the bayonet of a clamp connection type audio wire distribution frame is protected.
