[0074] The pressing mechanism 6 presses the screw holes ③B3 and ④B4 of the spring piece B at the diagonal positions, and then pre-tightens the screw in the screw hole ①B1 and locks the screw in the screw hole ②B2 in sequence. After the pressing mechanism 6 releases the spring piece B, the screw in the screw hole ①B1, the screw in the screw hole ③B3 and the screw in the screw hole ④B4 are locked in sequence, so that when the spring piece B is tightened, the gaps between the four corners of the spring piece B and the base plate A are the same and the force is evenly applied, which reduces the possibility of the spring piece B being squeezed due to tightening the screws, and effectively reduces the difficulty of assembling the spring piece B.
