A device for pressing materials guided by rollers for a carpentry cutting includes a device body, two base body fixing blocks, an adjustment mechanism and two pressing mechanisms. The device body includes a fist base body and a second base body. The two base body fixing blocks are arranged to press both sides of the base body, respectively. The adjustment mechanism includes a pushing mechanism configured to move the two pressing mechanisms along a direction from the first base body toward the second base body, two compressing mechanisms configured to compress a play between the first base body and the pressing mechanisms and a reset mechanism. Each of the pressing mechanisms includes a roller fixing block connected with the sliding block, and two rollers with a same rolling direction, the two rollers are respectively mounted on both sides of the roller fixing block.

The present invention provides an automated data destruction system to remove data effectively and reliably from a mobile communication device. The system comprises a platform, a securement mechanism, a positioning mechanism, a power drill, a vision recognition system, and a controlling system. The vision recognition system and the processor identify the mobile communication device, and the controlling system controls the securement mechanism, the positioning mechanism, and the power drill to a corresponding location based on the identified mobile communication device and activates the power drill to penetrate the mobile communication device at an exact depth to restrict the damage to the flash memory chip.
