As shown in fig. 1 and 2, the supporting pad 40 is disposed on the fastening member 30, and the supporting pad 40 is located between the head 34 of the bolt 31 and the mounting leg 11, so that a distance between the head 34 of the bolt 31 and the mounting leg 11 is equal to a distance between the supporting pad 40 and the mounting leg 11, that is, the supporting pad 40 can increase the clamping length between the head 34 of the bolt 31 and the nut 32, thereby reducing the wear between the bolt 31 and the mounting leg 11 and reducing the connection rigidity between the bolt 31 and the mounting leg 11. In addition, the elastic deformation amount of the bolt 31 and the mounting leg 11 is increased, and the clamping length between the head 34 of the bolt 31 and the nut 32 is increased, so that the reduction amount of the pretightening force of the fastening piece 30 can be reduced, and the risk of non-rotation loosening of the fastening piece 30 can be reduced.

As shown in fig. 2, the thickness of the support pad 40 is d1, and d1 satisfies the following relation: d1 is more than or equal to 10 mm. The thickness setting of supporting pad 40 is greater than 10mm, like this in error range, can increase the centre gripping length between the head 34 of bolt 31 and the nut 32 as far as possible, thereby can reduce the degree of wear between bolt 31 and the installation stabilizer blade 11, reduce the rigidity of being connected between bolt 31 and the installation stabilizer blade 11, also can reduce the decline volume to fastener 30 pretightning force, reduce the non-rotatory not hard up risk of fastener 30, thereby can improve the connection reliability of thrust rod subassembly 1, and adopt the mode of supporting pad 40 can reduce the installation degree of difficulty of thrust rod subassembly 1, can improve the installation convenience of thrust rod subassembly 1.
