The cylinder drive on the side wall of the support frame 8 can perform horizontal reciprocating motion. The bottom end of the movable seat 9 is movably connected with a power contact 10. The power contact 10 is driven by a cylinder fixed on the side wall of the movable seat 9. The cylinder is a prior art and will not be described in detail here. The power contact 10 is located above the limit seat 3. The contact finger at the bottom end of the power contact 10 is driven by installing an electric push rod, so that the length of the power contact 10 can be easily adjusted to have screen contact. When the bottom end of the power contact 10 is pressed on the surface of the screen, the movable seat 9 and the power contact 10 are driven to reciprocate, so that the screen touch test can be realized. The bottom end of the workbench 1 is bolted Two supporting legs 4 are symmetrically fixed to support the workbench 1. Support plates 5 are fixed on the side walls of the two supporting legs 4 by bolts for support, and the overall stability of the two supporting legs 4 is improved. A condenser 6 is fixed on the top of the supporting plate 5 by bolts for heat dissipation and cooling of the coolant. A compression pump 7 is fixed on the surface of the supporting plate 5 close to the condenser 6 and is connected to the condenser 6. The compression pump 7 can compress the coolant and transport it to the inside of the condenser 6. A notch 12 is opened inside the base 2, and a heat dissipation pipe 13 is installed at the bottom of the notch 12. The heat dissipation pipe 13 is made of stainless steel. The two ends of the heat dissipation pipe 13 are connected with the output end of the condenser 6 and the input end of the compression pump 7 in sequence.

When the temperature of the mobile phone display screen rises, the operator starts the compression pump 7 to compress the coolant into the condenser 6 for condensation and cooling, and then transports the coolant through the pipeline to the heat pipe 13 for heat exchange. The coolant is a prior art and will not be repeated here. The heat pipe 13 is spirally shaped to increase the contact area with the bottom end of the limit seat 3.
