[0002] In the field of decoration engineering, the paint-free board, as an environmentally friendly, beautiful and easy-to-process board material, has been widely used. However, during the installation process of the paint-free board, the exposed edges on its sides are prone to moisture and damage, affecting the overall aesthetics and durability. Therefore, edge banding treatment for the sides of the paint-free board has become a necessary construction step.

[0003] Traditional edge banding treatment methods often rely on manual operations, using materials such as glue and edge banding strips for pasting. This method is not only inefficient but also difficult to ensure the accuracy and consistency of edge banding. At the same time, after edge banding is completed, it is often necessary to cut off the excess edge banding strips to achieve a neat and beautiful effect. This step requires additional tools, such as a utility knife, for fine operation.

[0004] In addition, most of the utility knives on the market have a single function and cannot meet the cutting requirements at different angles during edge banding treatment. When cutting off the edge banding strips, users usually need to frequently replace the blades or adjust the cutting angles, which not only increases the complexity of the operation but also reduces the work efficiency.

[0005] In view of the deficiencies in the above background art, the present invention proposes an adjustable-angle portable multi-functional utility knife and its supporting edge banding device. Through an innovative angle adjustment system, the utility knife realizes the rapid adjustment and locking of the blade angle, meeting the cutting requirements at different angles during edge banding treatment.
