The drive cylinder 9 serves as a transmission power element for operating the drive shaft 7.

[0029] The driving shaft 7 is in a plate-like structure, wherein the plate-like structure is convenient for assembly and disassembly, and the structural plane is suitable for assembling the transmission connector 8 .

[0030] There are four groups of slide rail assemblies 5, and every two groups are installed in an upper and lower structure with the support arm 3. The design of the slide rail assembly 5 cooperates with the support arm 3 to complete the deformation guiding process.
