Clamping assembly includes first claw and second claw are disposed on base plate and configured to pick and place circuit board. Second driving device is disposed on base plate. Second driving device is connected to clamping assembly so as to move first claw and second claw toward or away from each other.

Abstract: A protection cap for use with a fiber coupler having at least a first housing comprises a casing defining a passage therethrough for receiving at least a portion of the housing, and a covering lid pivotally assembled to the casing for enclosing an end of the passage.

Abstract: An LCD panel test apparatus for testing a liquid crystal display (LCD) panel of a notebook computer by a photo detector. The LCD panel test apparatus includes a base, a moving device, a rotary device and a clamping holder. The moving device is disposed on the base and is provided with a mounting portion for mounting the photo detector. The position of the photo detector can be changed by the movement of the moving device. The rotary device is disposed on the base. The clamping holder, for clamping the notebook computer, is disposed on the rotary device. The position of the notebook computer can be changed by the rotation of the rotary device and the clamping holder. Therefore, the LCD panel can be tested at different angles. As a result, the brightness testing of the LCD panel can be performed easily and accurately.

Abstract: A crutch includes a tube having a handle fixed on top. The handle includes a knife engaged in the tube. An extension is slidably engaged in the tube and includes an upper end adjustable relative to the tube and secured to the tube by a projection. A tool head includes a stud for engaging with the extension. The tool head may be a tip member, an axhammer or a shovel. A coupler is secured to the extension, and a quick coupler may further be engaged with the tool head so as to secure the tool head to the coupler.
