Abstract
A hand-pulled device for winding binding strap, including a base seat, a fastening mechanism drivable by a movable arm and a winding mechanism having a winding reel for winding the binding strap thereon. A pivotally swinging track of the movable arm relative to the base seat defines a movement space. The outer rim of the wound binding strap is at least partially enclosed in the movement space for minifying the volume of the hand-pulled device.
Claims3
A hand-pulled device for winding a binding strap, comprising:
- a base seat having a first connecting section and a second connecting section distal from each other;
- a rotary shaft assembly pivotally disposed on the first connecting section of the base seat;
- a fastening mechanism including a movable arm pivotally connected with the rotary shaft assembly, the movable arm having a pair of symmetrically disposed arm boards laterally spaced one from the other and defining a handle space therebetween, the movable arm being pivotally swingable to drive a locating mechanism for driving and rotating the rotary shaft assembly;
- a winding reel rotatably connected to the second connecting section of the base seat;
- and
- a binding strap extending through the rotary shaft assembly, one end of the binding strap being connected with the winding reel, the binding strap being windable on an outer circumference of the winding reel to form an outer rim, the movable arm being pivotable over the winding reel and the outer rim of the wound binding strap being passed through the handle space.
