摘要

The device has a button (4) whose end is passed through a handle (1) and introduced into a transversely open receiving groove to abut against an abutment rib (23). A positioning extrusion (24) is engaged selectively with one of positioning openings (31, 32), so that an article (3) is received in the groove, or swivels relative to the handle by an angle between the article and the handle. The button abuts against an abutment plate (21) when a user presses the button, and the extrusion is disengaged from the positioning opening such that the article rotates freely relative to the handle. The article is a glazing knife.
