Mechanical Speed Switching in Tire Repair Tools for Stable Output

The patent replaces the electronic speed control system with a mechanical speed control system. The mechanical system uses a speed changing switch that directly mechanically connects to the transmission gear unit, eliminating electronic components and their vulnerable wire connections. This substitution maintains speed control capability while eliminating the reliability issue caused by vibrations loosening electronic connections.

The patent removes the electronic speed control system entirely from the tire repair tool, extracting the problematic electronic components and their vulnerable connections. By eliminating these components, the patent avoids the reliability issues associated with loose wire connections while preserving the essential speed control function through a purely mechanical alternative.

The patent merges the speed changing switch directly with the transmission gear unit, integrating the control mechanism into the existing mechanical structure. This merging eliminates the need for separate electronic control components and their vulnerable connections, while the integrated mechanical design maintains operational simplicity. The speed changing switch is positioned to directly interact with the transmission gears, creating a unified mechanical control system.

The mechanical speed control system is designed to be self-contained and self-regulating. The speed changing switch automatically engages different gear ratios through pure mechanical interaction without requiring external electronic control signals or complex wiring. The system uses the existing kinetic energy and mechanical movements of the tool to operate the speed control, making it self-sufficient and eliminating vulnerable external connections.
