The invention discloses a lifting appliance, and belongs to the technical field of lifting devices. The lifting appliance comprises a lifting body, a lifting block and a driving assembly, the liftingblock is provided with a first end and a second end, the lifting block is rotatably connected to the lower end of the lifting body, the lifting block has a first state and a second state, orthographicprojection is carried out on the lifting body, in the first state, the projection of the first end and the projection of the second end are located outside the projection of the lifting body, in thesecond state, the projections of the first end and the second end are located in the projection of the lifting body; and the driving assembly enables the lifting block to be switched from the first state to the second state and/or from the second state to the first state. According to the lifting appliance, when the lifting block is kept in the second state, the lifting block can extend into a through hole of a lifting piece along with the lower end of the lifting body, and after the lifting block is switched to the first state at the proper position, the lifting piece can be lifted by liftingthe lifting body upwards, so that compared with the fact that a traditional lifting appliance is used for lifting, the lifting operation is greatly simplified, the lifting time is shortened, the lifting efficiency is improved, and the man-hour cost is reduced.

    本发明公开的吊具,属于吊挂装置技术领域,包括:吊体,吊体竖直设置;吊块,吊块具有第一端和第二端,吊块转动连接于吊体的下端,吊块具有第一状态和第二状态,对吊体进行正投影,在第一状态时,第一端和第二端的投影位于吊体的投影外;在第二状态时,第一端和第二端的投影位于吊体的投影内;驱动组件,驱动组件使吊块从第一状态切换至第二状态和/或从第二状态切换至第一状态;本发明的吊块保持在第二状态时可以随吊体的下端伸入到吊取件的通孔内,并在合适位置,吊块切换至第一状态后,即可通过上提吊体的方式将吊取件吊挂,相较于使用传统的吊具进行吊挂时,极大的简化了吊挂操作,降低了吊挂工时,提高了吊挂效率,降低了工时成本。
