With the above structure, an electric vacuum pump is installed to extract the air in the pillar and the suction cup, so that the suction cup is adsorbed on the touch screen body to fix the touch screen body. When the touch screen body is removed, the electric vacuum pump is used to put air into the suction cup, and the suction cup releases the adsorption of the touch screen body. Through the slide groove and the slider, the electric vacuum pump moves with the pillar.

Compared with the prior art, the external protection structure of the touch screen has the following advantages:

1. Place the touch screen body on the suction cup in the protective shell, so that the suction cup can absorb the touch screen body, and then fix the touch screen body in the protective shell through the fixing mechanism. After fixing, fix the protective frame on the protective shell. The shockproof sponge layer can protect the screen of the touch screen body.

2. By installing shock-absorbing springs and pillars, the suction cup is made elastic, so that there is an elastic space at the rear of the touch screen body adsorbed on the suction cup. When the protective shell falls on the ground and the rear collides with the ground, it plays a shock-absorbing and protective role on the back of the touch screen body.

3. By installing the fixing plates and springs, the distance between the two fixing plates can be adjusted according to the width of the touch screen body. The touch screen body is clamped between the two fixing plates. The rubber pad can prevent the tension between the fixing plates from damaging both sides of the touch screen body. At the same time, the springs and rubber pads also provide protection for the touch screen body.

4. By installing an electric vacuum pump, the air in the pillar and the suction cup is extracted through the electric vacuum pump, so that the suction cup is adsorbed on the touch screen body to fix the touch screen body. When the touch screen body is removed, the electric vacuum pump is used to put air into the suction cup, and the suction cup releases the adsorption of the touch screen body. Through the slide groove and the slider, the electric vacuum pump moves with the pillar.
