Tool Adapter Quick-Release Structure for Handheld Screwdrivers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional handheld tools lack a convenient mechanism for removing, repairing, or replacing internal components due to their design, requiring the replacement of entire tools rather than individual parts, which is inefficient and inconvenient.
Innovation Solution
A tool adapter quick-release structure featuring a seat portion, engagement portion, movable sleeve, installation pin, and elastic member, allowing for easy installation and removal of screwdriver shafts through a locking mechanism that facilitates quick release and repair of components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a threaded connection method is used to fasten the operating element to the holding element, then the connection strength is improved, but the ease of removal deteriorates
Solution Approach 1:
The patent employs a dynamic locking mechanism where the locking sleeve can move between locked and unlocked positions. The spring element provides continuous axial force to maintain engagement, while the ball-shaped locking elements can be displaced to release the screwdriver tool. This dynamic design allows strong connection during operation while enabling quick removal when needed.
Solution Approach 2:
The locking mechanism is segmented into distinct functional elements: the locking sleeve, spring element, and ball-shaped locking elements. This segmentation allows each component to perform its specific function independently - the spring provides continuous force, the balls provide locking engagement, and the sleeve provides the interface for both locking and removal operations.
2Reliability
If the entire tool is replaced instead of individual parts, then the reliability is improved, but the loss of substance increases
Solution Approach 1:
The tool is designed with replaceable screwdriver tools that can be independently exchanged. This segmentation allows only the worn or damaged screwdriver tool to be replaced rather than the entire handheld tool, reducing material waste while maintaining the reliability of the main tool body.
Solution Approach 2:
The design enables selective replacement of consumable or wear-prone components (screwdriver tools) while retaining and reusing the durable main tool body. This approach recovers the value of the main tool for continued use while discarding only the necessary replacement parts.
3Manufacturing precision
If the locking sleeve is designed with threaded connection, then the manufacturing precision is improved, but the ease of manufacture deteriorates
Solution Approach 1:
The locking sleeve incorporates a dynamic spring element that automatically maintains engagement force. This eliminates the need for precise threaded connections during assembly, as the spring provides continuous axial force to keep the ball-shaped locking elements engaged with the screwdriver tool, simplifying the manufacturing process.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables users to easily install and remove screwdriver components, extending the tool's lifespan by allowing for individual part replacement without needing to replace the entire tool, thus improving operational efficiency and convenience.
Implementation Method 1
an elastic member abutted against the installation pin to push the movable sleeve along an axial direction

AI summary
A tool adapter quick-release structure includes an adapter and a locking mechanism. The adapter includes a seat portion and an engagement portion extended forward from the seat portion, and an installation hole formed to penetrate into the seat portion via the engagement portion. The locking mechanism includes a movable sleeve mounted onto the seat portion, an installation pin inserted into the movable sleeve and an elastic member abutted against the installation pin to push the movable sleeve axially, and the movable sleeve allowing a fixation member to penetrate through the seat portion to protrude outward inside the installation hole via push of the elastic member. The seat portion includes a repair hole corresponding to the installation pin and is connected to the installation hole.
