Connector 22 is connect with compressing member 23 by the second revolute pair a2；
Actuator 21 is translated with follower link 22, when connector 22 translates, compressing member 23 is driven to turn around the first revolute pair a1
It is dynamic.
So set, the translation by connector 22 more can easily make compressing member 23 lift or fall.Such as attached drawing 1
On the basis of shown direction, connector 22 drives compressing member 23 to turn right around the first revolute pair a1, compressing member 23 to when right translation
The one end for resisting welding is lifted, and the replacement of welding can be carried out.After replacement, connector 22 drives compressing member to left
23 turn left reset around the first revolute pair a1, and compressing member 23 is fallen, and compress welding.And connector 22 and compressing member 23 pass through the
Two revolute pair a2 connections allow the translation of connector 22 and the rotation of compressing member 23 synchronous progress without interfering with each other.Actuator
