Disclosed is a hindered-to-flip-up structure for a desktop lifting platform, wherein the desktop lifting platform includes a lifting column, and a supporting plate that rises or descends with the lifting column; the hindered-to-flip-up structure is disposed on the supporting plate; the supporting plate includes a fixing plate and a flip plate in rotatable connection with the fixing plate; a limiting device is provided on the supporting plate; when the flip plate rotates downwardly, the limiting device limits the flip plate from downward rotation; the flip plate is free to rotate upwardly. Further disclosed is a desktop lifting platform adopting the hindered-to-flip-up structure. The disclosures offer advantages of better protecting the desktop lifting platform and protecting items on the desk from being excessively crushed and crashed. The disclosures are mainly placed on a work platform such as a desk.

Workstation for a user (10), in particular intended for a user's (10) keyboard work, the workstation (11) comprising a working surface (12) which is movable in relation to the workstation (11), a motor (16) arranged to drive the working surface (12) of the workstation (11), when the workstation (11) with the working surface (12) thereof is situated on a first lower vertical level (LL), downward and forward from an upper position (UTP) to a lower position (LTPSit) and from said lower position (LTPsit) back to said upper position (UTP) according to a determined length of stroke (42, 43) of a first movement pattern, wherein said motor (16) is adapted to drive said working surface (12) of the workstation (11) when the workstation (11) with the working surface (12) thereof is situated on a second upper vertical level (UL) in a second movement pattern deviating from the first movement pattern.
