  • the hook 74 is hooked on the inner side wall surface of the skate bracket 10. Because the pressing spring 75 will top press the pressing block 73 toward the opening direction of the fastening groove 72, and the hook body of the fastener will also face the opening direction of the fastening groove 72, at this time, the fastener will be firmly hooked in the through-hole fastener 70, thus preventing the hidden danger that the folding locking wrench 41 will be turned over or opened after accidental collision during sliding.
  • another embodiment of the fixing part 7 comprises magnets which are respectively provided on the outer side walls of the folding locking wrench 41 and the skate bracket 10 and can be mutually attracted together.
  • the state after the folding locking wrench 41 is vertically turned over in the above embodiment is the overlapping state that the side wall of the folding locking wrench 41 is adhered to the wall surface of the accommodating groove 411 on the outer side wall surface of the skate support 10 (refer to the attached drawing for details).
