AI Technical Summary

⚠Technical Problem

During use, the extended rod of the existing multi-purpose folding shovel is prone to sliding and retracting along the inner side of the shovel handle due to external forces or its own weight, which affects the stability of operation and ease of use. In particular, in scenarios where it is necessary to maintain the extended length of the rod, frequent adjustments will reduce work efficiency and may lead to tool loss of control or uneven force on the user.

⚗Method used

The design incorporates fixed and limiting components, including a transmission component and a limiting component. The extension rod can be quickly adjusted and fixed through the threaded connection of the synchronous pulley and the threaded rod. The limiting component precisely restricts the position of the rotating shaft through the cooperation of the return spring and the limiting post, ensuring the stability of the shovel head. The outer side of the shovel handle is equipped with an anti-slip pad to increase friction and prevent slippage.

🎯Benefits of technology

In complex scenarios, the extension rod can be quickly adjusted and fixed, improving efficiency, ensuring tool stability during high-intensity operations, guaranteeing operational safety and stability, preventing loosening or accidental flipping, and enhancing ease of use and safety.
