In operation, the auxiliary measuring member 20 is first installed to the concave side of the bending deformation portion 210 of the product 200, at this time, the auxiliary measuring member 20 is kept horizontal, and the distance value between the lower surface of the auxiliary measuring member 20 and the lowest point of the concave side is the maximum bending deformation value of the product 200; then, the auxiliary measuring part 20, the measuring screw 40 and the product 200 are respectively electrically connected with the controller 10; immediately after the stepping motor 30 is started, the stepping motor 30 drives the measuring screw 40 to extend out and contact with the auxiliary measuring part 20, and the controller 10 starts counting; the measuring screw 40 pushes the auxiliary measuring member 20 to move close to the concave side of the bending deformation part 210 of the product 200 until at least one of the measuring screw 40 and the auxiliary measuring member 20 contacts the product 200, and the controller 10 stops counting; finally, the controller 10 calculates the number of turns of the measuring screw 40 according to the stepping motor, the number of steps of rotation and the step angle, and then calculates the distance value between the auxiliary measuring member 20 and the concave side of the bending part of the product 200 according to the product of the lead of the measuring screw 40 and the number of turns of rotation, that is, the maximum bending deformation of the product.
