Angled Support Surfaces for Detachable Dust Collection

The support surface is segmented into multiple inclined sections (first, second, and third sections) with different angles relative to the longitudinal axis. This segmentation allows the dust collection container to be detached through rotational movement while maintaining stable connection during operation, resolving the contradiction between connection reliability and detachment simplicity.

The support surfaces are designed with inclined sections that enable dynamic transition from a locked connected state to a detached state through rotation. The angled sections (particularly the third section with greater than 45° angle) facilitate easy detachment by converting rotational motion into axial separation, while the first and second sections maintain stable connection during normal use.

Instead of using complex three-dimensional cam mechanisms or lever systems for controlled detachment, the invention inverts the approach by using simple inclined planar surfaces. The angled support sections create a self-guided detachment path where rotation naturally translates to axial separation, simplifying the mechanism while maintaining controlled detachment.

The support surfaces utilize angular geometry rather than curved surfaces. The inclined sections with specific angles (particularly the third section with >45° angle) create sharp, defined detachment paths that guide the user through controlled separation without requiring complex three-dimensional curved mechanisms.

The simple axial plug connection is enhanced with inclined support sections that create dynamic locking. During assembly, the container is pushed axially onto the socket, establishing a simple connection. During operation, the inclined sections (first and second sections) engage to provide stable connection. For detachment, rotation engages the third inclined section to facilitate easy separation. This maintains manufacturing simplicity while ensuring connection reliability.

The connection mechanism transitions from purely axial movement to include rotational movement for detachment. The inclined support sections convert rotational motion into axial separation force. This adds a rotational dimension to the otherwise simple axial plug connection, maintaining ease of manufacture while improving connection reliability and controlled detachment.
