Description

Technical Field

[0001] The utility model relates to the technical field of strap tensioning and fixing equipment, in particular to a strap tensioning and fixing device. Background Art

[0002] Tie straps, also known as cargo strapping straps, are used to secure cargo during transportation, movement, loading, or storage. They have locking properties and will not fall off. They are safe, reliable, lightweight, easy to operate, and protect objects from damage. Tie straps require a tie strap tensioning and fixing device during use, which uses mechanical principles to tighten and secure the tie straps.

[0003] At present, most of the strap tensioning and fixing devices are mainly composed of a strap and a tensioning and fixing device. The connection between the strap and the tensioning and fixing device is achieved by putting one end of the strap on a screw and then fixing it with a nut. After the strap tensioning and fixing device has been used for a period of time, the strap is severely worn and needs to be replaced. However, the existing disassembly method requires the use of tools for disassembly, which makes the disassembly more cumbersome, and the disassembled nut is small, which may cause the nut to be lost, making it inconvenient to use.
