Quick-turn Driving Tool Auxiliary Handle Rotation Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driving tools often cause collisions between the handle portion and the user's hand due to the design, leading to discomfort and inefficiency during operation.
Innovation Solution
A driving tool with a body featuring a first rod and a second rod, along with an auxiliary handle that allows for free rotation and adjustable engagement, enabling the user to hold the auxiliary handle and the second rod separately for comfortable and efficient operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user holds the sleeve element and rotates the main body, then the driving tool can operate, but a collision easily occurs between the handle portion and the user's hand
Solution Approach 1:
The driving tool is divided into two separate grip zones: the auxiliary handle and the second rod. The user can hold the auxiliary handle while the second rod rotates independently, or hold the second rod while the auxiliary handle remains stationary. This segmentation separates the rotation function from the gripping function, eliminating the collision between the handle portion and the user's hand.
2Ease of operation
If the auxiliary handle is freely rotatable relative to the first rod, then the user can hold the auxiliary handle and second rod separately for comfortable operation, but the structure becomes more complex
Solution Approach 1:
The auxiliary handle is integrated with the first rod through a shared rotational axis, allowing both components to rotate together or independently. The engaging member connects the auxiliary handle to the first rod's receiving slot, creating a unified structure that provides flexible gripping options without requiring separate mounting mechanisms.

AI summary
A driving tool includes a body and an auxiliary handle. The body includes a first rod and a second rod perpendicular to each other. The first rod includes an insertion hole and at least one receiving slot. The second rod is mounted between two opposite ends of the first rod. The auxiliary handle includes a connection slot mounted on the body and an engaging recess. An adjusting member is mounted in the insertion hole and movable in relation to the first rod. At least one engaging member is received in the receiving slot and the engaging recess and is abutted against the adjusting member. Thus, the auxiliary handle is freely rotatable relative to the first rod.
