Abstract: A support and cushioning device for supporting and holding an electronic device includes a first supporting assembly, a fixed bracket, an adjusting board, and a plurality of elastic members. The adjusting board is mounted to the distal end of the first support assembly. The fixed bracket is elastically mounted to the adjusting board by means of a plurality of elastic members. The fixed bracket includes a base body and a plurality of holding arms extending out from a periphery of the base body. The plurality of holding arms and the base body cooperatively define a holding space for holding an electronic device.

Abstract: A housing includes a bottom housing and a top housing. The bottom housing includes a connecting surface. The top housing includes a bottom surface. The connecting surface is fixed to the bottom surface by welding. A receiving groove is defined in the bottom surface, for receiving the molten slag generated and collected during a welding process.

Abstract: A machining device includes a support platform, a machining assembly, a clamping assembly, a driving assembly, and a controlling assembly. The support platform includes a first supporting member, a sliding rail mounted on the first supporting member, and a second supporting member mounted on the sliding rail. The machining assembly mounted on the second supporting member includes a machining tool. The clamping assembly is mounted on the first supporting member, for clamping and rotating the workpiece. The driving assembly is fixed to the second supporting member. The controlling assembly includes a connecting member mounted on the second supporting member and a resisting member mounted on the connecting member. The driving member drives the second supporting member to slide along the sliding rail, to make a gradual and increasing depth of contact by the machining tool on the workpiece, until a preset limit is reached.
