Hand Tool Bit Holder Structure for Multi-Size Secure Clamping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hand tool positioning devices require multiple units for different bit specifications, increasing user inconvenience and cost.
Innovation Solution
A hand tool holding structure comprising a first body, second body, multiple third bodies, an elastic member, and a fifth body, allowing for the clamping of drive members of varying sizes and specifications through movable locking portions and inclined planes, facilitated by an elastic member for secure fitting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple positioning devices are used for different bit specifications, then each device can securely hold its specific bit size, but the number of devices and cost increases
Solution Approach 1:
The positioning device incorporates multiple receiving slots of different sizes (first receiving slots for standard bits, second receiving slot for larger bits) and multiple abutting portions that can be selectively engaged. This allows a single device to securely hold bits of various specifications, eliminating the need for multiple separate positioning devices while maintaining reliable holding for each bit size.
2Device complexity
If a single positioning device is used for all bit sizes, then device complexity is reduced, but the ability to securely hold different bit specifications is compromised
Solution Approach 1:
The positioning device is segmented into multiple functional zones: first receiving slots for standard-sized bits, a second receiving slot for larger bits, and multiple abutting portions (first, second, and third abutting portions) that can be selectively engaged. This segmentation allows each zone to be optimized for specific bit sizes while maintaining secure holding capability across all specifications within a single device.

Function Achieved in This Case
Enhances versatility by securely holding drive members of different sizes and specifications, reducing the need for multiple positioning devices and lowering operational costs.
Implementation Method 1
The elastic member is mounted on the second pivot portion and hidden in the third receiving slot. The elastic member is elastically biased between the second abutting edge and the second abutting portion.

AI summary
A hand tool holding structure includes a first body, a second body, multiple third bodies, a fourth body, an elastic member, and a fifth body. The first body has a first pivot portion, a second pivot portion, a mounting portion, multiple first receiving slots, a first abutting edge, and a second abutting edge. The second body has a second receiving slot, a first abutting portion, a third receiving slot, and a second abutting portion. Each of the third bodies has a locking portion, a first inclined plane, an abutting face, a second inclined plane, and a third abutting portion. The fourth body has a fourth receiving slot, a fifth receiving slot, and a third inclined plane. The elastic member is mounted on the second pivot portion and biased between the second abutting edge and the second abutting portion. The fifth body is mounted on the first body.
