Connection Rod Tool Holder With Positioning Member Anti-Theft Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tool holders are not anti-theft, allowing connection rods to be easily stolen as they can be disengaged by simply moving the tubular portion away from the band, making them inconvenient to secure and assemble.
Innovation Solution
A tool holder design featuring a main body with a hanging, assembling, and abutting portion, including engaging blocks and a positioning member that radially abuts the connection rod's body and stepped portion, preventing disengagement by engaging the tubular portion with the block and abutting the stepped portion, and optionally being screwed or pivoted for enhanced security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a band is used to bind the connection rod to the board portion, then the connection rod can be secured to the tool holder, but it is inconvenient to bind and disengage the connection rod
Solution Approach 1:
The tool holder is divided into distinct functional portions: an assembling portion with engaging blocks for securing the tubular portion, and an abutting portion for positioning the body portion. This segmentation allows each part to perform its specific function independently, improving both ease of operation and reliability.
Solution Approach 2:
The positioning member is extracted as a separate component from the main board portion. It can be independently assembled to the tool holder and provides precise positioning for the connection rod without requiring a band to wrap around the entire assembly, making installation and removal more convenient.
2Reliability
If a conventional band-based tool holder is used, then the connection rod can be held, but it is not anti-theft and connection rods may be stolen easily
Solution Approach 1:
The positioning member is inserted into and nested within the structure of the tool holder's abutting portion. This nested configuration provides a compact, integrated anti-theft mechanism that prevents theft without requiring complex external structures or multiple separate components.
Solution Approach 2:
The engaging blocks are designed with asymmetric geometries that match corresponding features on the connection rod. The tubular portion engages with protruding engaging blocks while the body portion abuts against the positioning member, creating an asymmetric engagement that provides secure anti-theft holding while maintaining simple overall structure.
3Ease of operation
If the tubular portion is simply moved away from the band, then the connection rod can be disengaged, but this makes the tool holder vulnerable to theft
Solution Approach 1:
The positioning member and engaging blocks are designed to create preliminary resistance to disengagement attempts. The abutting portion prevents radial movement of the body portion, while the engaging blocks on the assembling portion prevent removal of the tubular portion, thereby preemptively countering theft attempts before they can succeed.

AI summary
A tool holder is provided for at least one connection rod to be assembled thereto. Each connection rod has a body portion and a tubular portion greater than the body portion in radial dimension, and a stepped portion is formed between the tubular and body portions. The tool holder includes a main body and a positioning member. The main body includes a hanging portion, an assembling portion and an abutting portion, the assembling portion includes at least one engaging block for one said tubular portion to be engaged therewith, and the abutting portion is for radially abutting against the body portion. The positioning member is assembled to the main body, a side of the positioning member facing the abutting portion is for radially abutting against the body portion, and an end of the positioning member facing the assembling portion is for abutting the stepped portion.
