Abstract: An impact platform (30) for use in drop testing includes a bottom plate (33), a lift plate (31), a bracket (35), and an action member (37). The lift plate is parallel to the bottom plate and capable of moving up and down relative to the bottom plate. The bracket is slidably connected between the lift plate and the bottom plate. The bracket comprises two frames (36, 38) connected to each other and being capable of rotating relative to each other about a common axis. Each frame has a first connecting portion (363, 383) attached to the lift plate and a second connecting portion (365, 385) attached to the bottom plate. The action member is rotatably insertable into the first connecting portions or the second connecting portions of the two frames of the bracket for controlling the movement of the lift plate.

Abstract: A clamping fixture (1) is used for clamping an enclosure of a device. The clamping fixture includes a first clamp member (12), a second clamp member (13), and an adjusting pole (5). The first clamp member includes a first clamping portion (127) with a first contacting surface. The second clamp member includes a second clamping portion (137) with a second contacting surface. The second contacting surface is parallel to the first clamping portion. The first and the second clamping portions are configured for cooperatively clamping the enclosure of the device between the first and the second contacting surfaces. The adjusting pole has a first end threadedly engaged in the first clamp member and an opposite second end threadedly engaged in the second clamp member. The adjusting pole is adjustably movable relative to the first and the second clamp members along a lengthwise direction thereof.
