Innovation Solution
A quick release device for nail guns featuring a quick release mount, pulling base with an engaging hook, pivot hole, and elastic element, allowing for easy assembly and disassembly with reduced force requirements and a smooth surface to prevent workpiece damage, utilizing a pivotal rod and elastic element for efficient nail ejection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the turning frame provides sufficient force to abut against the panel during nail ejection, then the nails are successfully ejected without un-ejecting or random ejection, but the user must pull the pulling frame with considerable force making it laborious and prone to injury
Solution Approach 1:
The spring element acts as a counterweight mechanism, providing continuous abutting force against the panel to counterbalance the resistance force during nail ejection. This eliminates the need for the user to apply excessive pulling force, as the spring maintains the turning frame in constant contact with the panel, thereby ensuring reliable nail ejection while reducing operational effort and injury risk.
2Stability of the object's composition
If the panel has an uneven groove structure on its top surface, then the panel can be securely attached to the nail gun, but the uneven surface damages workpieces during abutting
Solution Approach 1:
The panel's top surface is segmented into multiple small protrusions instead of a single uneven groove structure. This segmentation distributes the contact points with the workpiece, preventing concentrated stress that causes damage. The multiple small protrusions maintain secure attachment stability while minimizing harm to the workpiece surface during abutting operations.
3Productivity
If the pulling frame is rotated relative to the panel to exclude problematic nails, then the nails can be quickly removed, but the considerable force required makes assembly and disassembly inconvenient
Solution Approach 1:
The spring element is pre-loaded to provide continuous abutting force against the panel before the pulling operation begins. This preliminary action ensures that the turning frame is already in contact with the panel, eliminating the need for the user to apply excessive force to initiate rotation. The pre-positioned spring facilitates quick nail exclusion while making assembly and disassembly convenient.

AI summary
A quick release device for a panel of nail guns has a quick release mount, a pulling base, and an elastic element. The quick release mount is disposed on a body of a nail gun adjacent to a rear end of an ejecting track, and has two connecting boards and a pivotal rod connected to the two connecting boards. The pulling base is pressably connected to the quick release mount, selectively engages with a panel of the nail gun, and has an engaging hook, a pivot hole, and a pulling arm. The engaging hook is formed on the pulling base, and selectively engages with a limiting claw of the panel to limit a position of the panel relative to the ejecting track. The elastic element is mounted between the quick release mount and the pulling base to provide a returning force to the pulling base.
