This form of stage can be roughly divided into two types: natural stage and artificial stage. The natural stage is usually a natural body of water such as the ocean. Due to the characteristics of its natural environment, the risk factor is relatively high. When using the underwater stage, an anti-shear device is required to prevent the lifting stage from pinching people's feet.

[0003] After searching, the application number is "201320676642.4", which provides an anti-shear mechanism for the underwater lifting stage. When the feet of actors or scenery exceed the edge of the lifting platform, the lifting platform will touch the movable rod of the anti-shear mechanism, and the movable rod will move upward, and the sliding rod will further drive the tilt switch in the sealed cavity to move. The tilt switch is connected to the driving control system of the lifting platform. When the control system detects the movement of the tilt switch, it will immediately stop the movement of the lifting platform, thereby avoiding the occurrence of shear accidents.

[0004] When the actor's feet exceed the edge, the tilt switch at the bottom will be activated to facilitate the shearing of the feet. However, with this structure, the stage stops after the actor's feet pass through the edge, and the stage needs to be raised by the backstage lift, which makes the actor's performance discontinuous and affects the performance effect.
