Description

Technical Field

[0001] This utility model relates to the field of hooking device technology, specifically a hooking device structure. Background Technology

[0002] Current technologies for hook lowering mechanisms often neglect the issue of friction between rotating components. The connection between the rotating rod and related drive components (similar to a cam structure) is relatively rudimentary, resulting in significant friction during operation. This not only causes unnecessary energy loss, requiring greater power input to complete the operation, but also significantly shortens component lifespan due to heat generated by friction and component wear, increasing maintenance and operating costs. Frequent repairs and component replacements also affect the normal operating efficiency of the hook lowering mechanism, leading to jamming, loosening, and instability, ultimately making it inconvenient to use. Therefore, we have introduced a new hook lowering mechanism structure. Utility Model Content
