The invention discloses a mechanical linkage mechanism which comprises a first joint, a second joint, an upper pipe, a front pipe and a rear pipe. The first joint is hinged to the second joint; the near end of the upper tube is fixedly connected to the first joint; the near end of the rear tube is fixedly connected to the second joint; the near end of the front tube is hinged to the first joint; the front pipe is provided with a guide groove extending linearly, the first joint is provided with a sliding structure in sliding fit with the guide groove, and the sliding structure can slide in the extending direction of the guide groove, so that when the first joint and the second joint rotate relatively, the front pipe and the upper pipe are folded/unfolded towards the rear pipe synchronously. The device has the beneficial effect that the contradictory relation between the operation sensitivity and the firmness is relieved.

    本发明公开了一种机械联动机构,包括第一关节、第二关节、上管、前管、后管;所述第一关节和第二关节相铰接;所述上管的近端固定连接在第一关节上;所述后管的近端固定连接在第二关节上;所述前管的近端铰接在第一关节上;所述前管设有线形延伸的导向槽,所述第一关节设有和导向槽滑动配合的滑动结构,所述滑动结构可沿导向槽的延伸方向滑动,使得所述第一关节和所述第二关节相对转动时,所述前管和所述上管同步地向所述后管收拢/展开。本发明的有益效果在于,解除了操作灵敏程度和牢固性之间存在的矛盾关系。
