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.

Abstract: A linkage mechanism includes: a base member; a first link rotatably connected to the base member, the first link defining a first arc-shaped guide groove centered on a pivot axis about which the first link rotates relative 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 including a linear actuator and a transmission member that is driven by the linear actuator, the transmission member having a first end rotatably connected to the output shaft, and a second end slidably received in the first arc-shaped guide groove. When the linear actuator drives the connecting member to extend and move, the second end of the transmission member abuts against one end of the first arc-shaped guide groove, which drives the first link to rotate relative to the base member.
