The invention discloses a test turntable, a fixture and a using method thereof. The test turntable and the fixture are core parts of a railway through ground wire bending tester, the test turntable isfixedly connected with a rotary output shaft of the tester, the test turntable is step-shaped, an upper step of the test turntable is cylindrical, and the fixture for fixing the end part of a throughground wire is rotatably fixed on a lower step of the test turntable. According to the test turntable and the fixture, the bending of the fixed end of the through ground wire in the test process is effectively avoided, the problems of the test turntable of the existing through ground wire bending tester are solved, and the normal operation of a bending test is ensured. 一种试验转盘和卡具及其使用方法，该试验转盘和卡具是铁路贯通地线弯曲试验机的核心部件，试验转盘与试验机的旋转输出轴固定连接，所述试验转盘为台阶状，试验转盘的上部台阶为圆柱形，用于固定贯通地线的端部的卡具可旋转地固定在试验转盘的下部台阶上。该试验转盘和卡具，有效避免了贯通地线在试验过程中固定端头的弯折，解决了现有贯通地线弯曲试验机试验转盘存在的问题，保证了弯曲试验的正常进行。
