Strain gauge fixing device for vehicle body structure load test

The utility model relates to the technical field of load testing, in particular to a strain gauge fixing device for a vehicle body structure load test. The utility model provides the strain gauge fixing device for the vehicle body structure load test, which can straighten the strain gauge during bonding and avoid the change of the resistance value of the strain gauge caused by improper tensioning of the strain gauge. A strain gauge fixing device for a vehicle body structure load test comprises a mounting plate, buckles, fixing belts and a piece stretching mechanism, the buckles are connected to the upper sides of the front portion and the rear portion of the mounting plate in a bilateral symmetry mode, the fixing belts are connected between every two adjacent buckles, and the piece stretching mechanism is arranged on the mounting plate. The connecting block is connected with the strain gauge through the adhesive, the connecting block is driven by the adjusting block and the pull rope to move towards the sides
