By setting the first receiving groove 26, the angular offset between the first mounting part 21 and the first mounting base 4 during the assembly process can be avoided, which would lead to assembly errors. During installation, firstly, the first blade 22 is clamped and fixed in the mounting groove between the first clamping block 23 and the first clamping block 23 by several locking screws 25 and locking nuts. Then, the first mounting part 21 is placed in the gap between the first mounting base 4 and the two first buckles 64.
