Rotatable Hook Device for Nailers Using Grooved Rear Plug
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional nailers have fixed hooks that cannot be adjusted arbitrarily, causing inconvenience to users as the position of the nailer cannot be customized according to specific needs.
Innovation Solution
A hook device for a nailer featuring a ring-like hook that is firmly and rotatably positioned using a rear plug with positioning grooves and a positioning unit, allowing the hook to be mounted and adjusted as needed, with a fastener causing the rear plug to bulge out and engage with the ring-like hook, enabling arbitrary positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the hook is fixed unrotatably to the nailer, then the hook is firmly positioned, but the position of the nailer cannot be adjusted arbitrarily
Solution Approach 1:
The hook is designed to be rotatable relative to the nailer body, transforming from a static fixed connection to a dynamic adjustable connection. The user can rotate the hook to any desired angle and secure it in position, providing adaptability in positioning the nailer while maintaining a relatively simple structure through the rotation mechanism
2Adaptability or versatility
If the ring-like hook is made rotatable on the rear plug, then the nailer can be positioned arbitrarily, but the hook positioning stability may be compromised
Solution Approach 1:
The positioning mechanism is divided into discrete components: positioning grooves cut into the rear plug body and corresponding positioning protrusions on the hook. This segmentation allows the hook to be rotated to different positions and locked into specific grooves, providing both flexibility in positioning and stability through the defined groove-protrusion engagement points
Solution Approach 2:
The positioning grooves are pre-formed in the rear plug during manufacturing, creating predetermined stable positions before the hook is installed. This preliminary preparation ensures that when the hook is rotated and positioned, it can be reliably secured in the intended location without requiring additional stabilization mechanisms

AI summary
The present invention relates to a hook device which can be firmly positioned on a nailer, wherein a fastener is used to insert in the rear plug by cooperating with a ring-like hook, so as to make the rear plug slightly bulge out to press against the ring-like hook, thus, the ring-like hook is firmly fixed to the rear plug. The hook device can be arbitrarily and rotatably positioned on the nailer, wherein a plurality of positioning grooves are formed on the step circular wall of the rear plug, and a ring-like hook is mounted on the rear plug. The ring-like hook is provided with a positioning unit which is to be engaged in the positioning grooves of the rear plug, so as to enable the ring-like hook to be rotatably positioned on rear plug. Thereby, the user can position the nailer arbitrarily according to real needs.
