Hand Device Based on Two-step Force Orthogonal Amplification Mechanism of Linkage and Pinion and Rack Mechanism

A kind of hand pressure amplifying device based on two-step orthogonal force amplifying mechanism of linkage with self-locking function on passing the critical position and pinion and rack mechanism is introduced.Working principle and technologic characteristic are both analyzed,and calculating formulae is also given.The mechanism not only utilizes the self-locking and force amplifier function of toggle force amplifier on passing the critical position,but also goes along the second force amplifier by two-step orthogonal mechanism of linkage.The effect of device is better than conventional force amplifier mechanism.
