When the two first moving rods 209 are moved to a suitable position (the automobile parts need to be supported), the two electric push rods 105 are suspended at the same time. When the two soft pads 215 are tightly in contact with the surface of the automobile parts, the corresponding two hand screws 212 are stopped, and then the four second moving rods 210 on the corresponding placement plate 216 are moved inside the corresponding mounting holes 208. At this time, each of the moved second moving rods 210 will drive the anti-slip pad 211, the corresponding hand screw 212, the corresponding mounting seat 213 and the corresponding soft pad 215 connected thereto to move. When each second moving rod 210 is moved to a suitable position, each hand screw 212 is screwed in turn.
