Abstract: An electronic device is provided. The electronic device is adapted to be disposed on a mounting surface. The electronic device includes a device body, a connection base and a bracket. The connection base is connected to the device body. The connection base is adapted to be rotated between a first orientation and a second orientation relative to the device body. When the connection base is in the first orientation, the connection base is connected to the device body. When the connection base is in the second orientation, the connection base is separated from the device body. The bracket is wedged against the connection base, wherein the bracket is adapted to be affixed to the mounting surface.

Abstract: A core assembly for the linear motor comprising a first core, a second core, a space, a tube division, a first assembly part and a second assembly part is provided. The first core comprises a first yoke, a first surface and a second surface wherein the first surface and the second surface are configured on the opposite sides of the first yoke, and a plurality of first teeth are configured on the second surface. The second core comprises a second yoke, a third surface and a fourth surface wherein the third surface and the fourth surface are configured on the opposite sides of the second yoke, the third surface corresponds to the first surface, and a plurality of second teeth are configured on the fourth surface. The space is formed between the first yoke and the second yoke. The tube division is contained within the space. The first assembly part and the second assembly part are positioned between the first surface and the third surface in the form of complementary configuration.
