Abstract: A tool-hanging rope includes an extendable and retractable connecting band unit and two retaining ring units. The connecting band unit includes a pleated cloth band and a plurality of main resilient strings extending within the pleated cloth band along the length of the connecting band unit and connected to the pleated cloth band by knitting. The retaining ring units are fastened respectively to two opposite ends of the connecting band unit. One of the retaining ring units includes a retaining ring that is openable to allow a tool to be sleeved thereon and that is closable to prevent the tool to be removed therefrom.

Abstract: A stretching apparatus includes two U-shaped frames and two pivot couplers which pivotally interconnect joint ends of the U-shaped frames. At least one coupler includes a U-shaped pivot seat and a slider. The pivot seat has two opposite upright walls and a bottom bight portion. Two adjacent joint ends of the U-shaped frames are pivotally connected to the pivot seat adjacent to the bottom bight portion to prevent downward pivotal movement of the U-shaped frames toward one another. The opposite upright walls have two pairs of positioning holes above the bottom bight portion. One of the walls has a perpendicularly extending extension plate.
