When a person sits on the chair, the piston moves downwards under the influence of the gravity of the person and transmits the gas in the cylinder into the constant pneumatic cylinder through the gas guide pipe. The constant pneumatic cylinder is used for keeping constant air pressure and releasing pressure and exhausting air through the first one-way air outlet valve. The gas that invariable pneumatic cylinder exhausted makes the flabellum rotate, and first pivot rotates simultaneously, and the clockwork spring on the first pivot is continuous to be wound up tightly, and until invariable pneumatic cylinder exhaust is accomplished, the flabellum is static. After the constant pneumatic cylinder finishes exhausting, the clockwork spring on the first rotating shaft starts to be loosened, the elastic potential energy of the clockwork spring is converted into kinetic energy, and the clockwork spring on the second rotating shaft starts to rotate reversely to wind the clockwork spring. The second rotating shaft correspondingly rotates, the gear on the second rotating shaft correspondingly rotates, the gear is meshed with the rack plate, and the rack plate correspondingly moves upwards until the rack moves out of the opening. When a person uses the workbench, the opening is moved out from the seat to the chair to the rack plate, a certain time is needed, and the time is used for regularly reminding the person to have a rest. When the person leaves the chair after using the work bench, the second one-way air inlet valve introduces air into the cylinder, the piston and the seat cushion correspondingly move upwards, the chair is ready for standby, and all the rest structural units are static. When the person sits again on the chair, the above process will be repeated again.

The beneficial effect of this scheme lies in: through setting up a series of structure subassemblies to utilize the self gravity of people to come corresponding messenger each subassembly work, reach the purpose of regularly reminding the people to have a rest. The workbench is ingenious in design, simple and practical. The workbench of the scheme can regularly remind people without additional deliberate operation, and is concise in operation, convenient and fast.
