  • Linkage mechanism
    Patent number: 10208842
    Abstract: A linkage mechanism includes a pivot assembly, a gear assembly, and a linkage assembly. The pivot assembly pivots around a first rotation axis. The gear assembly is pivoted with the pivot assembly and moves in conjunction with the pivot assembly. The gear assembly includes a cam, and the cam pivots around a second rotation axis. The second rotation axis is not parallel to the first rotation axis. The linkage assembly is disposed at a side of the gear assembly and contacts the cam. When the pivot assembly drives the gear assembly to pivot, the linkage assembly abuts against the cam to produce a relative movement with the cam.
