Optionally, the upper pressure plate is a transparent acrylic plate.

Optionally, the base is further provided with an elastic thimble which abuts against the lower bottom plate.

Optionally, the device further comprises a pen rack, wherein a magnetic control pen is arranged on the pen rack, the bottom of the pen rack is exposed out of the magnetic control pen point, and a guide pillar is arranged at the bottom of the pen rack and matched with the guide groove.

Optionally, a hook is further disposed on the base, and the hook is engaged with one end of the guide plate away from the pivot.

Optionally, the device further comprises a converter, one end of the converter is provided with a connector, the other end of the converter is provided with a USB interface, the connector is connected with a power line and a signal line of the touch screen, and the USB interface is connected with a computer for testing.

Compared with the prior art, the touch screen testing device of the die disclosed by the invention has the advantages that the lower base plate is arranged on the base, the touch screen is clamped between the guide plate and the lower base plate, the guide plate is rotated, the touch screen is pressed, and the magnetic control pen is subjected to continuous scribing movement along the guide groove, so that the scribing action is completed. And the power line and the signal line of the touch screen are connected with a converter and further connected with a testing computer, and the testing computer is used for supplying power to the touch screen and displaying a testing result. Because the scribing test is carried out before the touch screen is not assembled on the electronic product, unqualified scribing test after assembly is avoided, and screen disassembly and screen replacement are required, so that manpower and material resources are saved.
