Operation Rod Connection Structure for Quick Tip Tool Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connection structures for long-reach operation rods, such as screw fastening types, face difficulties in efficiently attaching and detaching tip tools due to complexity and time-consuming disengagement processes, especially when deep engagement is required, which hampers work efficiency.
Innovation Solution
A connection structure featuring an engagement pair with a main body, a moving body, and a floating piece that can be fitted into a recessed part, allowing for easy alignment and locking of the tip tool, enabling quick attachment and detachment with minimal effort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a screw fastening type locking structure is used to prevent loosening, then the connection stability is improved, but the time required for attachment and detachment increases
Solution Approach 1:
The locking structure is segmented into a locking piece that can independently engage with the locking groove, separated from the rotating part. This allows the locking action to be decoupled from the rotation operation, enabling quicker attachment without requiring complex rotation of a locking mechanism.
Solution Approach 2:
The locking function is extracted from the rotating part and implemented by a dedicated locking piece that automatically engages with the locking groove when the engagement part is inserted. This eliminates the need to rotate a locking mechanism, reducing the time for attachment and detachment while maintaining connection stability.
2Reliability
If deep engagement is required for secure connection, then the connection stability is improved, but the rotating part must be moved away more, increasing the time for detachment
Solution Approach 1:
The locking mechanism is segmented so that the locking piece operates independently from the rotating part. The locking piece engages with the locking groove through a simple insertion motion, allowing deep engagement for stability without requiring the rotating part to be moved away for detachment.
Solution Approach 2:
The locking function is extracted and implemented by a locking piece that engages automatically during insertion. This eliminates the need to rotate or move away any component for detachment, as the locking piece can be simply pushed back to disengage, regardless of engagement depth.
3Adaptability or versatility
If multiple tools are used for work, then the versatility is improved, but the time for repeated attachment and detachment increases
Solution Approach 1:
The operation rod is designed with a universal engagement part that can connect to various types of tools through the standardized locking mechanism. The simple insertion-based locking allows quick attachment and detachment of multiple different tools, reducing the time penalty associated with tool changes while maintaining versatility.

AI summary
Provided is a connection structure of an operation rod in which a connection object such as a tip tool can be easily attached to and detached from the operation rod in a relatively short time without causing a fixed state. The main body is inserted into the cylindrical operation rod on the tip side. An engagement pair is formed of an engagement part with a notch provided to the main body on a tip side and an engagement part with an engagement pin provided to a tip tool. An inner slider on which a recessed groove is formed in a circumferential direction is relatively slidably disposed to the main body on an inner diameter side. An outer slider is relatively slidably disposed to the main body on an outer diameter side, wherein an opposing recess which can oppose to the recessed grove is formed on the outer slider.
