PURPOSE: An apparatus for fixing specimens of an electric fatigue testing machine is provided to minimize error of an operator, as stabilizing abnormal experiment probability and condition. CONSTITUTION: An apparatus for fixing specimens of an electronic fatigue testing machine includes a main body (100), a holder (200), a rotating member (300), a pair of guides (400) and a pair of fixing jigs (500). A lifting unit (600) is installed in the main body. The holder is installed on the upper part of the lifting unit, and a retainer (10) inserted with a number of metal balls is placed on the upper part. The rotating member is installed on the upper part of the holder as being able to be lifted and rotated horizontally, and applies friction force to the metal balls on the upper part of the retainer. The pair of guides is installed on both sides of the main body to have length up and down, and is able to move horizontally. The pair of fixing jigs is installed so that one end of the outer side slides on the guides, and one end facing with each other supports both ends of the holder respectively. |
