Automatic test clamp

The utility model relates to an automatic test clamp which has an opening / closing device. A cover body of the clamp can be independently opened and closed in an electric mode or a pneumatic mode when the utility model is not limited by other mechanisms, and a hook bottom and a hook claw which are respectively arranged at the cover body and the clamp are matched with each other; thus, the hook claw can be clamped with the hook bottom and can cause the hook bottom to be pulled downward when the cover body is closed; so the probes which are positioned at the cover body and the lower part of a PC board can be contacted with the PC board, and the PC board needs to be tested; thereby, the a connecting point can be tested, and the clamp automation is realized; so the work efficiency is raised, and the generation probability of the professional injury is decreased. The utility model is used for testing the connecting point of the PC board, and the utility model has the function that the cover body can be opened and closed automatically.
