The multifunctional push handle 6 is made of 45# steel that is quenched and blackened. The two holes at the bottom match and are locked with the chain conveyor chain. It can follow the movement of the chain when it moves, thereby playing the role of transporting thin plates. The long straight rib of the multifunctional push handle 6 is made into an 83° bevel. Through simulation analysis, it can be known that this design can effectively convert the force generated by the chain into thrust to a greater extent and reduce the force loss in the process. At the same time, the equidistant hollowing of the center can not only make it easier to release the internal stress of the push handle during production and ensure the accuracy of each size, but also reduce the weight of the push handle itself to ensure maximum force transmission.
