Switching Pliers Head Tool for Fastening and Cutting Clamping Bands
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tools for clamp connecting require two separate tools for fastening and releasing, which increases operator weight, inconvenience, and potential damage to pipes due to the pry method used for releasing.
Innovation Solution
A tool with a switching structure incorporating a left and right pliers head, an eccentric shaft, and a cover plate system that adjusts the distance between the pliers heads to enable both fastening and cutting of clamping bands with a single tool, reducing weight, volume, and cost while enhancing stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two separate tools are used for fastening and releasing clamp connecting, then the functionality is complete, but the operator weight increases and convenience decreases
Solution Approach 1:
The patent combines fastening and releasing functions into a single tool by integrating two pliers heads (fastening pliers head and releasing pliers head) that can be switched between. This merging reduces the number of separate tools needed, thereby decreasing operator weight while maintaining complete functionality for both fastening and releasing operations
Solution Approach 2:
The single tool is designed with multi-functionality by incorporating both fastening pliers head and releasing pliers head that can be switched. This universal design allows one tool to perform multiple functions (fastening and releasing), eliminating the need for separate specialized tools and reducing overall equipment weight
2Adaptability or versatility
If two separate tools are used for fastening and releasing, then the functionality is complete, but the convenience decreases
Solution Approach 1:
By merging fastening and releasing functions into one tool with switchable pliers heads, the operator handles only one tool throughout the operation. This eliminates the inconvenience of switching between separate tools and improves ease of operation while maintaining full functionality
Solution Approach 2:
The tool incorporates a switching structure that dynamically changes the configuration between fastening and releasing modes. This dynamic switching capability allows the tool to adapt its function based on operational needs, enhancing convenience by providing seamless transition between different operational states
3Ease of operation
If the pry method is used for releasing clamp connecting, then the releasing function is achieved, but the pipes are damaged
Solution Approach 1:
The releasing pliers head acts as an intermediary tool that performs releasing operations without direct contact between the pry tool and the pipe. This intermediary mechanism enables the releasing function to be achieved while preventing harmful effects on the pipe by using a dedicated releasing pliers head designed for safe operation
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The tool achieves dual functionality with reduced weight and cost, increased stability, and convenience by using a switching structure that allows for efficient transition between fastening and cutting states without heat consumption, minimizing material damage.
Implementation Method 1
The switching structure includes an eccentric shaft which is eccentrically and rotatably disposed, to adjust the distance between the left pliers head and the right pliers head when the left pliers head and the right pliers head clamp tightly

AI summary
This invention provides a tool with a function of fastening and cutting a clamping band, including a left pliers head, a right pliers head and a switching structure. The right pliers head and the left pliers head cooperate with each other to fasten and cut the clamping band. The switching structure is disposed at the left pliers head and the right pliers head to adjust the distance between the left pliers head and the right pliers head when the left pliers head and the right pliers head clamp tightly. The tool with the function of fastening and cutting the clamping band provided in this invention achieves one tool with two functions.
