AI Technical Summary
Technical Problem
Existing cutting devices lack internal support when cutting round tubes, which makes the cutting area prone to deformation and is not suitable for cutting round tubes of different sizes.
Method used
An elastic pressing mechanism is installed on the guide sleeve. The guide sleeve contains a guide block and a push rod. The guide block pushes the push rod to move radially to support the inner wall of the round tube. The cutting blade rotates in the opposite direction to the round tube. The positioning structure and driving mechanism ensure cutting stability.
Benefits of technology
It achieves minimal edge deformation during round tube cutting, has a stable positioning structure, is suitable for cutting round tubes of different sizes, and improves cutting quality and versatility.
