Abstract: A linkage mechanism includes: a base member; a first link having a first end rotatably connected to the base member; a second link rotatably connected to the first link; a connecting member rotatably connected to the base member and the second link; an actuating mechanism having a linear actuator, a pushing member, and a transmission member, the pushing member slidably connected to the output shaft, the pushing member having a pushing surface, the transmission member including a first end hinged to the pushing member, and a second end pivoted to the first end of the first link. When the output shaft extends to push the pushing surface, the pushing member moves and the first link rotates relative to the base member.
