[0032] A specific application of this embodiment is:

[0033] When the staff needs to use the device, they first place the car door panel between the multiple clamping plates 309, and then control the multiple hydraulic rods 304 to start simultaneously through the controller 101. The hydraulic rods 304 shorten and drive the connecting block 305 to move closer to the hydraulic rods 304. When the connecting block 305 moves, it drives the fixed shaft 306 to slide in the arc groove 311, and then pulls the L-shaped connecting rod 310 to rotate around the fixed shaft 2 308. When the fixed shaft 2 308 rotates, it drives the fixed shaft 313 to slide in the arc groove 2 312, and then The third fixed shaft 313 is squeezed to drive the clamping plate 309 to move toward the middle at the same time in the second slide rail 307. When the second slide rail 307 is close to the outer wall of the car door panel, the hydraulic rod 304 is continuously started to shorten the appropriate distance and apply pressure, so that the car door panel can be clamped and fixed by the second slide rail 307. Then, the car door panel can be welded by an external welding device. When the welding head cannot contact the car door panel, the motor 207 can be started by the controller 101. The rotation of the motor 207 can drive the left bidirectional threaded rod 206 to rotate, so that the left leather panel can be fixed. The pulley 212 rotates, and the rotation of the pulley 212 on the left can drive the belt 213 to rotate, so that the pulley 212 on the right rotates at the same time, and then the bidirectional threaded rod 206 on the right can rotate at the same time. When the bidirectional threaded rod 206 rotates, it can drive the slider 208 to slide in the slide rail 205. When multiple sliders 208 move toward the middle at the same time, the movement of the slider 208 can drive the limit shaft 209 to move, so that it squeezes the connecting rod 210. Since the limit shaft 211 limits the position of the connecting rod 210, the connecting rod 210 can gradually stand upright. The connecting plate 202 can be supported and raised, and the telescopic rod 201 can make the movement of the connecting plate 202 more stable. When one side of the automobile door panel is welded, the controller 101 simultaneously starts multiple electric telescopic rods 203. The extension of the electric telescopic rods 203 can drive the rack 204 to rise, thereby rotating the gear 302. The rotation of the gear 302 can drive the rotating shaft 301 to rotate as a whole, thereby turning the clamped automobile door panel over to facilitate welding on the other side.
