The invention relates to a fixing device for a metal sheet high temperature tensile extensometer, the fixing device fixes the high-temperature extensometer by upper and lower clamping blocks, whereinthe two clamping blocks in the form of a semicircular block are provided with through grooves at sample contact portions to fix a sample, and are provided with annular grooves at curved parts to facilitate connecting with the high-temperature extensometer by a fixing line. A guide rod of the fixing device is provided with a telescopic sleeve which is convenient for use of samples of different gauge lengths. The fixing device has the advantages of simple structure, convenient and easy operation AND low manufacturing cost, is suitable for high-temperature tensile tests of metal sheets of variousthicknesses and lengths, and effectively avoids the breakage of the fixing line, falling off of the extensometer and failed testing caused by direct contact with a thin plate sample at high temperature. 本发明涉及种金属薄板高温拉伸引伸计的固定装置
