  • the swing rod 37 , the gear A 35 and the gear B move along the axial direction of the driving shaft 34 with the driving shaft 34 .
  • the gear A 35 and the gear B enter the strip-shaped groove 31 and are clamped with the locking teeth 32 to lock the guide member 22 , so that it cannot move back and forth in the guide groove 23 .
  • the “horizontal state” of the folding locking wrench 41 in this embodiment uses the angle shown in FIGS. 18 to 23 as an example, that is, the open state of the folding locking wrench 41 )
  • the guide member 22 can be unlocked, and the hook 21 can be separated from the second skate hook 141 B hooked therewith, so as to achieve the purpose of disassembling the skate.
  • the shape of the U-shaped groove 36 in this embodiment is not limited to U-shape, but also can be provided as an oval shape with a long top side and a long bottom side.
  • a polygonal block 61 is fixedly sleeved at one end of the driving shaft 34 away from the folding locking wrench 41 , and the polygonal block 61 is coaxially provided with the driving shaft 34 .
  • the inner wall of the skate bracket 10 is also provided with a polygonal groove 62 , which can accommodate the polygonal block 61 .
  • the polygonal block 61 is inserted into the polygonal groove 62 , and the swing rod 37 and the driving shaft 34 are locked so that they cannot be reversed, achieving the effect that the locking hook 21 and the second skate hook 141 B hooked therewith are locked and cannot be separated from each other.
  • the guide member 22 can be unlocked, so that the locking hook 21 can be separated from its hooked second skate hook 141 B, and the purpose of detaching the skate 14 can be achieved.
  • the locking part 6 in this embodiment can also be implemented in combination with the first embodiment of the present disclosure, that is, the polygonal groove 62 provided on the inner wall of the skate bracket 10 is used to replace the clamping groove 60 in the first embodiment, and the polygonal block 61 is matched to replace the locking part 6 in the first embodiment.
  • a return spring 211 can also be provided at one end of the locking hook 21 , one end of the return spring 211 is top pressed and fixed on the side wall end of the locking hook 21 , and the other end thereof is top pressed and fixed on the inner wall of the hook accommodating cavity 13 .
  • the return spring 211 can automatically rebound the locking hook 21 , reducing the manual screwing time.
  • a fixing part 7 is further provided between the folding locking wrench 41 and the outer side wall of the skate bracket 10 , and the fixing part 7 is capable of fixing the folding locking wrench 41 on the outer side wall of the skate bracket 10 after the folding locking wrench is turned over vertically.
  • the fixing part 7 comprises a fastener 71 provided on the outer side wall of the folding locking wrench 41 , and a through-hole fastener 70 provided on the outer side wall of the skate bracket 10 into which the fastener 71 is inserted and clamped together.
  • the fastener 71 comprises: a fastening groove 72 provided at the tail end of the folding locking wrench 41 and provided with an opening; a pressing block 73 , one end of which extends out of the opening of the fastening groove 72 , and the other end of which is capable of moving back and forth in the fastening groove 72 ; a hook 74 , which extends outward from the pressing block 73 towards the wall surface of the outer side wall of the skate bracket 10 and is capable of being inserted into the through-hole fastener 70 to be hooked and fixed; a pressing spring 75 , which is provided between the pressing block 73 and the wall surface of the fastening groove 72 , and is capable of keeping the pressing block 73 extending outward.
  • the hook 74 extends into the through-hole fastener 70 , the hook 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 avoiding 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).
