The keyboard 5 is 420mm in length, 160mm in width and 31.5mm in thickness, mounting holes of the inner sliding rails 3 are formed in the two sides of the keyboard 5, the aperture is 5-M2.5mm, triangular rubber bulges are further arranged at the front ends of the two sides, the protruding length is 2.5mm, the depth is 7mm, the thickness is 5mm, and the rubber bulges deform to be embedded between the wave-shaped bulges of the tray 4 when being stressed.

The magnetic attraction 6 is an ultra-thin type magnetic attraction and comprises a body and attraction pieces, the length dimension is 35mm, the width dimension is 15mm, the body is arranged at the rear ends of two sides in the sliding rail frame 1, the attraction pieces are arranged at the front ends of two sides of the shell of the tray 4, and the total thickness is 3.4mm after the body and the attraction pieces are attracted.

The damping rotating shaft 7 is used for connecting and overturning the slide rail frame 1 and the tray 4, the maximum outer diameter is phi 27mm, the shaft diameters of two ends are phi 15mm and phi 12mm respectively, the diameter of the wire passing hole is phi 9mm, the torque of the rotating shaft is 20kgf.cm, and M2.5 threaded holes and phi 2.8mm countersunk holes which are uniformly distributed along the axis are formed in two ends of the rotating shaft respectively.

Panel 8 is used for fixed whole tilting mechanism, it is long to be 80mm, it is wide to be 37mm, thickness 8mm, 2M 3 screw holes through the side border are connected with slide rail frame 1, the upper and lower border of panel 8 one side stretches out length 10 mm's arch, the width is 4mm and 7mm respectively, thickness is 1.5mm, it is spacing to be used for the upset, panel 8's centre is equipped with length 21mm, width 6.4 mm's long circular slot, the groove back face is equipped with 2 heavy platforms, the size is 65mm x 12mm x 1.1mm respectively, 46mm x 8.5mm x 5.4mm, be used for installation spring 9 and latch hook 11.

The spring 9 is a compression spring, the diameter of the outer ring is 4mm, and the length is 20 mm.
