Through the guiding chute 703, the limiting member 702 can move along the surface of the guiding slider 701, so that the two groups of limiting members 702 move inwards, thereby driving the positioning pin 705 on the surface of the connecting member 704 to move inwards until the positioning pin 705 is clamped into the pin hole for positioning on the surface of the automotive steering part. At the same time, through the threaded connection between another group of positioning pins 705 and the front end of the upper surface of the support frame 3, the positioning of the automotive steering part is further fixed.

[0026] Please refer to Figure 4, a connecting member 704 is installed at the lower end of the front surface of the limiting member 702, positioning pins 705 are provided on the inner surface of the connecting member 704 and the front end of the upper surface of the support frame 3, a reference surface 706 is installed at the upper end of the front surface of the support vertical plate 5, a limiting frame 707 is provided at the lower end of the front surface of the support vertical plate 5, a support bar 8 is installed at the lower end of the rear surface of the support vertical plate 5, and a pressing assembly 9 for pressing the steering member is provided on the surface of the support bar 8.

[0027] The specific operation is as follows. When in use, start the electric push rod 901, so that the electric push rod 901 drives the support rod 902 to move forward, thereby driving the linkage plate 903 to extend outwards. During the movement of the linkage plate 903, its inner end rotates around the front end of the support rod 902, thereby driving the pressing clamp 904 to rotate around the surface of the fixed shaft 905, so that the rear end of the pressing clamp 904 rotates outwards, and then the upper end of the automotive steering member is clamped and fixed by the front end of the pressing clamp 904.

Further, the positioning pin 705 on the surface of the connecting part 704 is driven to move inward until the positioning pin 705 is clamped into the pin hole for positioning on the surface of the vehicle steering part. At the same time, through the threaded connection between another group of positioning pins 705 and the front end of the upper surface of the support frame 3, the positioning of the vehicle steering part is further fixed. Subsequently, the electric push rod 901 is started, causing the electric push rod 901 to drive the support rod 902 to move forward. Further, the linkage plate 903 is driven to extend outward. During the movement of the linkage plate 903, its inner end rotates around the front end of the support rod 902. Further, the pressing clamp 904 is driven to rotate around the surface of the fixed shaft 905, causing the rear end of the pressing clamp 904 to rotate outward. Further, the upper end of the vehicle steering part is clamped and fixed by the front end of the pressing clamp 904. At the same time, the hydraulic push rod 906 is started, causing the hydraulic push rod 906 to drive the pressing part 907 to move forward. Since the pressing part 907 is limited by the linkage rod 908, after the pressing part 907 moves forward to a certain position, its front end will rotate upward around the front end of the hydraulic push rod 906 until the upper end of the pressing part 907 fixes and limits the lower front side of the vehicle steering part. After welding is completed, the electric push rod 901 and the hydraulic push rod 906 are started to drive the pressing clamp 904 and the pressing part 907 to rotate and reset. Then, the limiting part 702 is moved outward to release the positioning of the positioning pin 705. The electric telescopic rod 10 is started, causing the electric telescopic rod 10 to drive the pushing plate 11 to move forward. The pushing plate 11 drives the ejector rod 12 to slide forward along the lower end of the support vertical plate 5, and the welded vehicle steering part can be pushed down.
