Tray shallow mechanism

The utility model provides a tray shallow mechanism, which comprises a frame, be equipped with a plurality of pushing rod support in the frame, pushing rod support is connected with the frame through linear bearing the bottom, and one side of pushing rod support articulates has the push rod, and pushing rod support's opposite side is equipped with the cylinder. Tray shallow mechanism, the cylinder provides the power that advances for shallow mechanism push rod, linear bearing guarantees that the push rod is in the horizontality at the in -process that advances, is unlikely to to fluctuate. Thereby guarantee that a whole set of mechanism is steady at the operation in -process, the smoothness. The spring provides automatic re -setting the function for the push rod, carries when coming when the tray, does benefit to the weight of tray self, pushes down the push rod, treats that the tray passes through the back, and the push rod is automatic to rebound. Its main characterized in that tray is when push rod top, an
