The invention discloses a flexible dexterous hand driven by piezoelectricity. The flexible dexterous hand driven by the piezoelectricity comprises a supporting platform body, three identical flexiblefingers, flexible connecting pieces, piezoelectric ceramic blocks and end actuators. The supporting platform body is regular polyhedron. The flexible fingers are evenly arranged on the outer side faces of the supporting platform body. The included angle between the adjacent flexible fingers is 120 degrees. The flexible fingers comprise front fingers and rear fingers, and the front fingers are connected with the rear fingers through the flexible connecting pieces. The piezoelectric ceramic blocks are bonded on the outer surfaces of the front fingers and rear fingers. The end actuators are installed at the tail ends of the front fingers. By controlling the magnitude and direction of the voltage applied to the two ends of the piezoelectric ceramic blocks, the piezoelectric ceramic blocks aredeformed accordingly, and the front fingers and rear fingers are driven to bend left or right. The end actuators are driven to grasp tiny electronic components flexibly and steadily in the micro-assembly and micro-operation of a micro-electromechanical system. Therefore, the flexible dexterous hand driven by the piezoelectricity has the advantages of simple structure, flexible movement and high grasping stability.

The invention provides a workpiece pressing device and a drill press workbench with the same, belongs to the technical field of operation, and solves the problem that the existing pressing device cannot meet requirements of pressing large workpieces. The workpiece pressing device comprises an oil cylinder, a guide rail assembly, a pressing arm, compression blocks and connection plates. The compression blocks and the connection plates are located on two sides of the pressing arm respectively and are fixedly connected with each other. Guide rails of the guide rail assembly are fixedly connected with pressing arm. A cylinder body of the oil cylinder is fixedly connected with the connection plates.
