[0002] Conductive foam is a flame-retardant sponge wrapped with conductive cloth. After a series of treatments, it has good surface conductivity and can be easily fixed on the device to be shielded with adhesive tape. During the production process of conductive foam, special testing equipment is required to detect its conductive properties.

[0003] In the process of conducting conductivity performance test of existing conductive foam, it is necessary to first attach two positive and negative electrode sheets to the top of the conductive foam, and then energize the two electrode sheets through the detection equipment to start the conductivity performance test of the conductive foam.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1.

When the inclined surface at one end of the trapezoidal block contacts the spherical rod, the spherical rod is pushed to drive the sliding seat to move away from the conductive foam. When the spherical rod is separated from the inclined surface at one end of the trapezoidal block and rests on its plane, the pressure plate continues to move downward and contacts the conductive foam for detection. The two sliding seats move away from the conductive foam respectively, thereby pulling the conductive foam to make it straight, thereby eliminating the deformation effect of the conductive foam in the soft state during the placement process, so that the subsequent conductive foam can maintain a good fit with the electrode sheet, thereby ensuring the accuracy of the detection.
