[0001] The present invention relates to the technical field of cargo securing, more particularly a safety securing device integrating a protection function. STATE OF THE ART

[0002] Lashing and securing devices are a particularly essential fastening tool in the transport of goods. Lashing straps, also known as load securing straps, are fastening devices used during the transport, movement, or handling of goods. They are equipped with a secure locking mechanism that prevents loosening or detachment. They are safe, reliable, lightweight, and easy to use. They protect objects from damage and, thanks to different types of hooks, are suitable for various environments. They are also known as lashing devices, fasteners, securing straps, or military lashing straps.

[0003] However, existing lashing devices present the following problems when used:

[0004] 1. In existing safety tie-down devices, the gear mechanism The retractable strap is usually integrated into the product; during retraction, incorrect assembly methods often cause the gear to jam, resulting in uneven retraction of the strap.

[0005] 2. The outer housing that holds the retraction spring is generally attached to using rivets at both ends. This fastening method is inherently unstable and results in high production costs.

[0006] 3. The external casing, which houses various small components, is often constructed of a The single piece has left and right sides. This design leads to alignment problems when assembling pins and other parts, as the folded edges prevent precise alignment of the holes, making assembly difficult and time-consuming.

[0007] 4. During the withdrawal process, many products available on the market do not They do not retract at a uniform speed; retraction that is too rapid risks causing the consumer's hand to hit something, which constitutes a safety hazard.

[0008] 5. Existing safety restraint devices have ends of exposed springs on the handle components, when users pull the handle, these protruding spring ends can injure their hands, creating a safety hazard.

[0009] Therefore, a safety tie-down device incorporating a protective function must be provided for use. CONTENTS OF THE INVENTION
