Abstract

The invention provides a clamping device. The clamping device comprises a driver, a driven part and two clamping jaws which are equally arranged in a sliding manner. Two symmetric inclined surfaces are formed on the driven part, and the driver drives the driven part to enable the two inclined surfaces to move; the two clamping jaws extend to form mutually-equal stress portions, and a clamping opening is formed between the two clamping jaws; the two inclined surfaces move to be in contact with the two stress portions in a pushing manner, and therefore the two clamping jaws are driven to move to clamp an opening relative to clamp shrinkage. Accordingly, the problem that a traditional clamp difficultly and precisely controls the clamping jaws to generate the closing motion is solved.
