Linkage mechanism and linkage fixture

The invention discloses a linkage mechanism and a linkage fixture, wherein the linkage mechanism comprises rod members, linkage pulling rods, a guide frame, sliders that can slide along the rod member, and linkage blocks that can move along the guide frame. The two ends of the linkage pulling rods are respectively hinged with the sliders and the linkage blocks, and the linkage pulling rods and thelinkage blocks of each linkage mechanism are two or more. When the sliders slide along the rod members, the linkage pulling rods drive the linkage blocks to move along the guide frame. The linkage mechanism has good mobile synchronization, and opposite linkage mechanisms can be simultaneously adjusted respectively. 本发明公开了种联动机构以及联动夹具，其中，种联动机构，包括杆件、联动拉杆、导向架、可沿杆件滑动的滑块以及可沿导向架移动的联动块，联动拉杆两端分别与滑块和联动块铰接，每个联动机构的联动拉杆和联动块均为两个以上，当滑块沿杆件滑动时，联动拉杆带动联动块沿导向架移动。本发明具有良好的移动同步性，能够分别对相对的联动机构同时进行调整。
