Strain gauge connecting and fixing device for test piece elasticity modulus test

The utility model discloses a strain gauge connecting and fixing device for a test piece elasticity modulus test. A plurality of wiring terminals are fixedly arranged at set positions of a chuck respectively. The signal output end of each wiring terminal is connected with the signal input end of an external tester through a wire. According to the utility model, the connection mode is a pressure embedded wire, the operation is simpler and more time-saving than the operation of welding the wire, and the operation can be completed within one minute. According to the utility model, the problems ofdisordered wire arrangement and strain gauge dragging by wires are completely solved; and the eight wires are fixedly arranged in pairs, so that convenience is provided for later instrument test output value arrangement. The connecting operation time is greatly prolonged, the strain gauges and the wires can be connected only by pressing the buckles downwards, the whole process can be completed within one minute, and a te
