[0042] The telescopic rod 11 and the auxiliary sleeve rod 12 on the docking plate 10 can push the limiting plate 13 to approach the automobile parts, and limit the automobile parts in the horizontal direction; the auxiliary sleeve plate 14 slidably connected with the outer wall of the limiting plate 13 is connected with the silica gel pad 15 at one end; under the action of the air pump 16, the gas in the telescopic pipe of the limiting plate 13 expands to push the silica gel pad 15 to approach and contact the automobile parts; the silica gel pad 15 plays a buffering role to avoid damaging the surface of the automobile parts; and the air volume of the air pump 16 can be adjusted according to the material and surface requirements of the automobile parts, so as to control the pressure of the silica gel pad 15 on the automobile parts, and the practicability of the whole is improved.
