The second connecting part 12 is located inside the end of the transverse support frame 42 and the second connecting part 12 is rotatably connected to the end of the transverse support frame 42 through a shaft assembly. When the cantilever 3 floats upward, the movable rod 13 extends into the movable sleeve 14, thereby compressing the spring 15. At the same time, the spring 15 provides a compressive force, causing the movable rod 13 to move out of the movable sleeve 14, providing a downward force for the cantilever 3. When the cantilever 3 floats downward, the movable rod 13 extends out of the movable sleeve 14, thereby stretching the spring 15. At the same time, the spring 15 provides a tensile force, causing the movable rod 13 to move into the movable sleeve 14, providing an upward force for the cantilever 3.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
