[0035] The chain 4 can be transported outward by the rotation of the winding roller 3, and the chain 4 will slide in the outlet shell 5 during transportation, so that the chain 4 can extend from the winding roller 3, and then the gravity part of the rotating component 6 is tilted toward the winding roller 3, so that the driving part of the rotating component 6 can move upward, and when the driving part moves, it drives the fixed component 7, so that the chain stopping part of the fixed component 7 can be engaged and limited in the chain 4, thereby fixing the chain 4 and preventing the chain 4 from extending outward, and the gravity part of the rotating component 6 is pulled obliquely upward by the steel cable, so that the gravity part cooperates with the driving part, so that the driving part can move downward, and when the driving part moves downward, it drives the fixed component 7, so that the fixed component 7 can be separated from the chain 4, thereby achieving the effect that the chain 4 can be wound up or extended outward.

[0036] Furthermore, when the fixing component 7 fixes the chain 4, one end of the locking component 8 is inserted into the hole of the gravity part of the rotating component 6, so that the gravity part can be limited, so that the chain 4 can be locked again after being fixed to prevent the chain 4 from loosening, and the locking component 8 is pulled upward by the steel cable, so that the locking component 8 can be separated from the gravity part of the rotating component 6, and the gravity part is pulled by the steel cable at the same time, so that the gravity part of the rotating component 6 can move downward.
