　　Summary:
　　Micro-electromechanical engineering, optics and photonics engineering, precision engineering, biomedical engineering and other fields, the rapid development of the urgent need to be able to sub-millimeter, micron-space micro-actuator micro-operation. Micro-actuators in micro clamp is important to perform a device that can be used to complete the object of holding a small, mobile, and assembly of such action, in the micro assembly, micro-manipulation has Strong magnets an important role. Existing micro-clamp in the clamping range, clamping force, the response speed, precision control, there are certain problems.
　　In order to overcome existing microgripper insufficient clamping force and clamping range of issues, this paper, a kind of giant magnetostrictive material (GMM) as the driving source of new microgripper carried out a systematic study. New micro-good 65Mn from the elastic clamp plate body made ​​using wire cutting, clamp structure is simple, using lever mechanism to amplify the output displacement. In addition, instead of the traditional with the flexible hinge hinges, easy-to-manufacturing, non-clearance and friction from lubrication and wear, good stability, can improve the precision of movement and life. Papers on giant magnetostrictive driven microgripper performance http://www.chinamagnets.biz/ test results showed that the new micro clamp with clamping range, fast response, high output accuracy, easy to control the clamping force advantages. The paper also carried out design calculations on the magnetic circuit, using ANSYS software to drive the magnetic field of the finite element analysis, and microgripper performance of the dynamic strength and stress analysis.
