If it exceeds the preset value, the electric air pressure valve performs pressure relief operation to avoid damage to automobile parts due to excessive pressure and deformation. At the same time, the hexagonal rubber plate is a flexible structure to better protect the parts and prevent the hard structure from causing wear to the parts or damage caused by excessive extrusion force.

The end of the sliding cylinder 11 away from the fixed cylinder 9 is rotatably connected to a universal joint 12, and the end of the universal joint 12 away from the sliding cylinder 11 is fixedly connected to a hexagonal rubber plate 13. The hexagonal rubber plate 13 is rotated at multiple angles through the universal joint 12 to adapt to the surface of automobile parts. At the same time, the hexagonal rubber plate 13 is made of rubber and is not a hard material, which can better protect the surface of automobile parts.
