CLAMPING APPARATUS FOR PRACTICAL TRAINING MATERIALS

摘要

A clamping device for an experiment practice is provided to firmly hold clamping and unclamping states by one pressing motion and to easily fix or separate a large box-type experiment practicing device to/from a table even in using plural clamping devices. In the clamping device for an experiment practice, rotating body operating units(140-1,140-2) are inserted into a support plate(110) to rectilinearly reciprocate. One of the rotating body operating units is protruded and the other is pushed inward on both sides of a clamp member rotating body(120) with facing each other. The clamp member rotating body is rotated in one direction to turn a clamp member(130) by pressing one side of the protruded rotating body operating unit and the other side of the pushed rotating body operating unit is projected out and settled in the correspondent position at the same time. When the other side of the protruded rotating body operating unit is pressed and inserted inward, the clamp member rotating body and the clamp member turned in one direction are rotated to an original state and one side of the pressed rotating body operating unit is projected out and settled in the correspondent position. Accordingly, an experiment practicing device is fixed to or separated from a table by repeating the steps.
