摘　　要：介绍了一种基于杠杆—斜楔—铰杆三级增力的冲击式手动夹具的工作原理,并给出了相关的力学计算公式。该夹具是手动敲击式的夹紧装置,能够在瞬间获得较大的作用力,而自锁则可以长时间保持输出力。A kind of impacting fixture based on lever-wedge-toggle three-step force amplifier is introduced. The calculating formulae of output force are also given. Using the mechanism, we can gain powerful force in moment by impacted the lever. And the self-locking is able to keep output force for a long time.
