Additionally, the term "substantially" may refer to slight imprecision or deviation in conditions, amounts, values, or dimensions, etc., some of which may be within manufacturing or tolerance limits.

Examples

As shown in fig. 1, 2, 3 and 4, a deformable desk comprises desk legs 1 and a desktop 10, wherein the desktop comprises a panel and left and right side plates 12, the left and right side plates of the desktop are respectively rotatably connected with a left lifting frame and a right lifting frame, and the desk legs, the lifting frames 2 and two parallel swing frames 3 are connected into a parallel four-bar mechanism through hinges; the table leg is connected with one of the swing frames through a telescopic control device, the telescopic control device is an air spring 4, and the height of the table top can be adjusted through the telescopic action of the air spring. The lifting frame is provided with a limiting blocking body 11 for limiting the rotating angle of the desktop, the bottom edge of the side plate can be supported on the limiting blocking body when the desktop is horizontal, and the bottom edge of the side plate is excessive with the side fillet. Through the rotation of the relative crane of manual messenger curb plate, the air spring cooperation is flexible, can realize the conversion of curb plate and spacing baffle contact position to angle modulation has been realized.

Wherein the left side board is connected with the lifting frame through a gear pin shaft, and the right side board is rotationally connected with the lifting frame through a rotating shaft 7.
