Fixing Gun Loading Device With Linkage Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fixing guns require manual reloading of fasteners, which is inconvenient and prone to inaccurate positioning, leading to inefficiencies in fastening operations.
Innovation Solution
A fixing gun with a loading device featuring a guide member and linkage mechanism, including a lower link and pins that engage guide grooves, allowing for automated and precise loading of fasteners into the gun body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual reloading operation is used, then the fixing gun can be operated, but the reloading process is inconvenient and time-consuming
Solution Approach 1:
The fastener is pre-positioned in the magazine before operation. The loading device automatically transfers the fastener from the magazine to the gun body when needed, eliminating the need for manual reloading operations during the fastening process.
Solution Approach 2:
The loading device is designed to automatically load fasteners into the gun body without requiring manual intervention. The system uses its own mechanical components (linkage mechanism, guide member, cam member) to perform the loading function autonomously.
2Manufacturing precision
If manual reloading operation is used, then the fixing gun can be reloaded, but the fastener positioning is inaccurate
Solution Approach 1:
The guide member acts as an intermediary component that precisely guides the fastener from the magazine to the gun body. The guide grooves on the guide member ensure accurate positioning of the fastener during the automatic loading process, eliminating positioning errors associated with manual operation.
Solution Approach 2:
The manual mechanical positioning operation is replaced by an automatic mechanical linkage system. The linkage mechanism, driven by the cam member, automatically positions the fastener with consistent precision that cannot be achieved through manual operation.
3Productivity
If automated loading device is added, then loading speed and precision are improved, but device complexity increases
Solution Approach 1:
The linkage mechanism serves multiple functions: it transfers the fastener from the magazine to the gun body, positions the fastener accurately, and resets the cam member for the next loading cycle. This multi-functionality reduces the need for separate components for each function.
Solution Approach 2:
The loading device components are arranged in a compact, nested configuration where the linkage mechanism moves within the space defined by the guide member and magazine structure. This efficient spatial arrangement minimizes the overall device complexity while maintaining full functionality.

AI summary
A fixing gun includes a gun body and a loading device. The gun body is for manipulation of a fastener, and has a loading hole. The loading device includes a guide member and a linkage mechanism. The guide member is formed with a first guide groove and a second guide groove. The linkage mechanism includes a lower link, a slide member, and a clamp assembly for holding the fastener. The slide member is disposed movably on the guide member. The lower link is pivoted to the slide member and the clamp assembly. During movement of the slide member relative to the guide member for moving the fastener into the loading hole, the lower link is alternatively engaged to the first guide groove and the second guide groove.
