[0028] Working Principle: This invention proposes a mobile phone screen touch sensitivity testing device. In use, a set of first fixed plates 3 are pulled outwards by the handle 31. The first fixed plates 3 drive the rack 33 to move synchronously, causing the gear 26 to rotate. The gear 26 then drives another set of racks 33 to move in the opposite direction, thus causing the two sets of first fixed plates 3 to move away synchronously. The mobile phone is then placed between the two sets of first fixed plates 3 with the screen facing upwards. The handle 31 then moves the two sets of first fixed plates 3 closer together, abutting against both ends of the mobile phone. The assist rod 51 drives the bidirectional screw 5 to rotate, causing the control plate 6 to move the two sets of control plates 6 closer together. During the movement, the control plate 6 guides the guide post 43 through the guide groove 61, causing the guide post 43 to move. The column 43 drives the two sets of second fixing plates 4 to move closer to each other. When the second protective pad 45 abuts against the side of the mobile phone, the telescopic block 44 is pressed into the interior of the second telescopic groove 46, causing the support rod 441 to squeeze the second airbag 47. The gas inside the second airbag 47 enters the interior of the first airbag 36 through the air guide tube 7, opening the first airbag 36 and causing the positioning block 37 to abut against the side wall of the positioning groove 22. When the positioning block 37 abuts against the side wall of the positioning groove 22, the bidirectional screw 5 will no longer be able to rotate. At this time, the first fixing plate 3 and the second fixing plate 4 abut against the four sides of the mobile phone, thereby achieving all-round fixation of the mobile phone and avoiding the problem of displacement of the mobile phone when the contact 13 performs actions on the mobile phone screen, thus improving the accuracy of the test.
