Abstract: A device for roasting beans which is significantly easier to install and place in a bean-roasting machine includes a chassis, a bean roasting tube, and a driving member. The chassis defines an accommodating cavity and a receiving hole communicating with the accommodating cavity. The bean roasting tube includes a rotating member and a chamber. The rotating member is detachably connected to the chassis. The chamber includes a first end plate, a second end plate opposite to the first end plate, and a bearing piece fixedly connected between the first end plate and the second end plate. The second end plate faces the receiving hole and is rotatably connected to the rotating member. The driving member is fixed to the first end plate and movable to drive the chamber to rotate in the accommodating cavity.

Abstract: A key structure includes a key body, a key portion disposed on the key body and installed inside a slot formed on a case of an electronic device in a movable manner, and an actuating portion disposed on the key body and synchronally movable with the key portion. The actuating portion includes two actuators for respectively actuating a corresponding electronic switch of the electronic device.

Abstract: A conductive elastic component for electrically connecting an electronic device with a cradle includes a plurality of fingers, a first metallic plate connecting first ends of the plurality of fingers, and a second metallic plate connecting second ends of the plurality of fingers. Each finger has a first end for being mechanically connected to the cradle, a first segment spanning between the first end and a first point, and a second segment spanning between the first point and a second end. The second segment of each finger has a curved contact region for contacting the input node of the electronic device. An angle between a line connecting the first point and the first end and a line connecting the first point and the second end is an acute angle. In addition, the centerline along the lengths of the first and second segments resides in a same plane.
