The invention discloses a lifting appliance which comprises a supporting frame and a clamping mechanism arranged on the supporting frame. The clamping mechanism comprises clamping jaws, a rotating shaft, a first connecting rod, a second connecting rod and a connecting plate; one end of the clamping jaw is connected with the rotating shaft; one end of the first connecting rod is rotationally connected with one end of the second connecting rod; the other end of the first connecting rod is connected with the rotating shaft; the other end of the second connecting rod is rotationally connected with the connecting plate; and the rotating shaft is rotationally connected with the supporting frame. When the connecting plate moves upwards, the connecting plate drives the rotating shaft to rotate through the second connecting rod and the first connecting rod and enables the clamping jaws to be folded and clamped. The connecting plate is driven to move upwards, so that the second connecting rod and the first connecting rod are linked with the connecting plate and drive the rotating shaft to rotate, and the clamping jaws are folded and clamped; when clamping is not needed, the connecting plate moves downwards under the action of gravity, and the clamping jaws are opened, so that the function of automatically clamping and separating a rear floor assembly can be achieved, operation is simple, and the labor intensity of workers is reduced.

    本发明公开了一种吊具,包括支撑架以及设置在支撑架上的夹紧机构,夹紧机构包括夹爪、旋转轴、第一连接杆、第二连接杆以及连接板,夹爪的一端与旋转轴连接,第一连接杆的一端与第二连接杆的一端转动连接,第一连接杆的另一端与旋转轴连接,第二连接杆的另一端与连接板转动连接,旋转轴与支撑架转动连接,当连接板向上运动时,连接板通过第二连接杆和第一连接杆带动旋转轴转动并使夹爪收拢夹紧。通过驱动连接板向上运动,使第二连接杆和第一连接杆与连接板联动并带着旋转轴转动,以使夹爪收拢夹紧,当不需要夹紧时,连接板在重力的作用下向下运动,使夹爪张开,从而可以实现对后地板总成自动夹紧和分离的功能,操作简单,降低员工的劳动强度。
