Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary fixing and quick release, in particular to an auxiliary fixing quick release hook. Background Art

[0002] With the continuous development of technology, the application of release hooks is becoming more and more extensive, especially in the field of sea vessels. For speedboats lowered by slides at the stern of the ship, it is necessary to use auxiliary fixed quick release hooks to reduce the fixing tension of the wire release winch, thereby increasing the service life of the equipment. In an emergency, violent treatment can be used to achieve the quick release requirement. The traditional auxiliary fixed quick release hook cannot adjust the fixing range of the fixed release hook according to the distance of the small boat on board at the stern of the ship. The small boat can only be fixed by changing the position of the small boat itself, which requires more manpower and reduces the fixing efficiency of the small boat. At the same time, if an emergency occurs, it is necessary to use violent treatment to quickly release the fixed small boat, which is extremely easy to cause damage to the fixed release hook, greatly reducing the practicality. Based on this, an auxiliary fixed quick release hook is now provided to eliminate the disadvantages of the existing device. Utility Model Content
