[0026] Specifically, the base 1 fixes the fixed block 4 so that the position of the fixed block 4 is fixed. The fixed block 4 is fixed on the base 1 by welding, so that the fixed block 4 is stable. The fixed block 4 limits the pin shaft 12 so that the pin shaft 12 can rotate stably. The pin shaft 12 can be fixed by the fixing nut. The mounting block 5 and the protective cover 6 limit the screw rod 8 so that the screw rod 8 can rotate stably.
