Small equipment e.g. box, opening device, has mechanism communicating with gear that transmits rotation movement to four axles equipped with blade carrier, where gear triggers opening or closing of blades
摘要
<p>The device has a mechanism (1) activated by a button or key (2). The button or key actuates the rotation of a main axle and a driving pinion. The mechanism communicates with a gear that transmits a rotation movement to four axles (8) equipped with a blade carrier (10). The gear triggers opening or closing of blades (17). A bevel pinion is fixed on one of the axles (8), and connection pinions are fixed on other three axles (8). An offset pinion inverses an original rotation direction. The diameter of the bevel pinion is less than that of the offset pinion.</p>
