Deep-hole socket driving shank assembly with quick release nuts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional deep-hole socket driving shank assemblies suffer from poor circularity between components, leading to deflection during rotation, integral construction preventing size and specification flexibility, and necessitating full assembly replacement when parts wear out, resulting in material waste and increased maintenance costs.
Innovation Solution
A driving shank assembly featuring a hollow straight tube with mounting portions, a drive head, a connector, and quick release nuts, allowing for coaxial alignment and detachable assembly, enabling operation with nuts of different sizes and specifications, and facilitating replacement of individual components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the tube and connecting member are formed integrally, then the assembly is simplified, but the driving head cannot be reused for nuts of different sizes and specifications
Solution Approach 1:
The patent divides the integral assembly into separate components: the tube, the drive head, and the connector are formed as distinct parts that can be assembled and disassembled. This segmentation allows the drive head to be removed and reused with different nuts while maintaining a simplified overall structure through modular design.
2Ease of manufacture
If the tube and connecting member are formed integrally, then manufacturing is simplified, but the entire assembly must be replaced when the driving head or connecting member is worn out
Solution Approach 1:
By forming the tube, drive head, and connector as separate components that can be assembled together, the patent enables selective replacement of worn parts. When the drive head or connector wears out, only that specific component needs to be replaced rather than the entire assembly, reducing maintenance costs and material waste while keeping the manufacturing process relatively simple.
3Ease of manufacture
If the tube and connecting member are not coaxial, then manufacturing is easier, but the tube is easily deflected during rotation
Solution Approach 1:
The patent incorporates preliminary alignment features in the design of the tube and connector, such as positioning protrusions and recesses, that ensure coaxial alignment is achieved automatically during assembly. This preliminary action of built-in alignment eliminates the need for complex post-assembly adjustments while ensuring rotation stability during operation.

AI summary
A driving shank assembly includes a tube, a drive head, a connector, and two quick release nuts. The tube has two mounting portions each provided with an external thread or a screw hole. The drive head is provided with an external thread or a screw hole. The connector is provided with an external thread or a screw hole. Each of the quick release nuts is provided with a first internal thread screwed onto the external thread of the tube or a first through hole locked onto the screw hole of the tube. Each of the quick release nuts is provided with a second internal thread screwed onto the external thread of the drive head and screwed onto the external thread of the connector or a second through hole locked onto the screw hole of the drive head and locked onto the screw hole of the connector.
