It could be a "ratchet strap" or a "spring-loaded securing bar."
These two types of tools are commonly used in daily life to secure goods, tie luggage, or organize furniture. They often have a tension adjustment device at the top. Their names and uses may vary slightly depending on their specific form. Here's a detailed distinction:
Ratchet Strap (Tightener): The main body is a metal or plastic rod with a metal hook and ratchet mechanism (tension adjustment device) at the top. When used, after wrapping it around the object, the strap is tightened by repeatedly turning the ratchet handle. It's commonly used to secure goods during truck transport and is also frequently used when moving furniture at home.
Spring-loaded Secure Bar (Telescopic Bar): Mostly a hollow metal bar with an internal spring or elastic cord, and rubber anti-slip tips at both ends. The length is adjusted by rotating the bar. It's used to hold items in places like cabinets or car trunks to prevent them from sliding, and is suitable for securing lighter items such as boxes and folding chairs.
Similar tools include "Velcro straps" (with hooks and loops) and "hook mesh bags" (with elastic cord mesh), which are more flexible for organizing wires and loose tools. When purchasing, pay attention to the weight-bearing parameters. For items weighing over 20 kg, metal ratchet straps are recommended, while telescopic poles are more suitable for securing small everyday items.
