摘要：
A universal holding frame provides convenience and safety for certain drill accessories which all have an elongate drivable shaft and a mounted storage barrel. The universal holding frame maintains the mounted storage barrel against rotation with the shaft of the drill accessory. It can contract and extend and be able to fit almost all drills.
