[0029] In this embodiment, the movable pin 21 is loosened counterclockwise, and the movable block 20 is moved to the left along the connecting box 22. The leftward movement of the movable block 20 causes the support block 11 to move to the left, the leftward movement of the support block 11 causes the support plate 1 to move to the left, the leftward movement of the support plate 1 causes the connecting shaft 2 to move to the left, the leftward movement of the connecting shaft 2 causes the adjusting plate 3 to move to the left, the leftward movement of the adjusting plate 3 causes the adjusting frame 9 to move to the left, and the leftward movement of the adjusting frame 9 causes the contact plate 10 to move to the left. After the movement is complete, the movable pin 21 is tightened clockwise to press against the connecting box 22. The manipulator moves the contact piece 14 to the right, causing the moving column 13 to move to the right. The moving column 13 moves to the right along the support block 11, stretching the tightening spring 12. The contact piece 14 moves to the right, causing the insertion column 15 to move to the right. The insertion column 15 moves to the right and is pulled out from the insertion slot in the middle. The manipulator adjusts the plate 3 and flips it along the support piece 1 via the connecting shaft 2. The rotating connecting shaft 2 causes the fixed plate 16 to rotate, causing the adjustment plate 3 on the front side to flip downward and the adjustment plate 3 on the rear side to flip upward. After adjustment, the contact piece 14 is released, causing the tightening spring 12 to rebound and move the moving column 13 to the left. The moving column 13 moves to the left, causing the contact piece 14 to move to the left. The contact piece 14 moves to the left, causing the insertion column 15 to move to the left. The insertion column 15 moves to the left and inserts into the corresponding insertion slot, fixing the fixed plate 16. Loosen the adjusting pin 5 counterclockwise, and manipulate the adjusting block 4 located at the top to move outward along the adjusting plate 3. The outward movement of the adjusting block 4 at the top causes the first connecting frame 6 located at the top to move outward. The outward movement of the first connecting frame 6 at the top passes through the adjusting rod 7 located at the top and causes the second connecting frame 8 located at the top to move outward. The outward movement of the second connecting frame 8 located at the top causes the contact plate 10 to flip outward through the adjusting frame 9. At the same time, the contact plate 10 flips outward to pull the second connecting frame 8 at the bottom to move inward. The second connecting frame 8 at the bottom moves the first connecting frame 6 at the bottom inward via the adjusting rod 7 at the bottom. The first connecting frame 6 at the bottom moves inward to move the adjusting block 4 at the bottom inward. The adjusting block 4 at the bottom moves inward along the adjusting plate 3. After adjustment, the adjusting pin 5 is tightened clockwise. Move the automotive parts to the inside of the contact plate 10, rotate the fixing rod 18 clockwise, and the fixing rod 18 moves inward, causing the clamping plate 19 to move inward, and the clamping plate 19 moves inward to contact the workpiece; Loosen the fixing pin 27 counterclockwise, manipulate the upper column 28 to move upward, which in turn moves the support column 26 upward. The support column 26 moves upward along the lower column 25. The upper column 28 moves upward, which in turn moves the connecting plate 29 upward. The connecting plate 29 moves upward, which in turn moves the moving frame 30 upward. The moving frame 30 moves upward, which in turn moves the welding head 31 upward. After adjustment, rotate the fixing pin 27 clockwise to tighten the support column 26. The second push rod motor 32 is started. The output end of the second push rod motor 32 moves backward, driving the push frame 33 to move backward. The push frame 33 moves backward, driving the moving frame 30 to move backward. The moving frame 30 moves backward, driving the welding head 31 to move backward. After the movement is complete, the second push rod motor 32 is turned off, and the first push rod motor 23 is started. The output end of the first push rod motor 23 moves to the left, driving the push block 24 to move to the left. The push block 24 moves to the left, driving the lower column 25 to move to the left, so that the welding head 31 moves to the welding position of the automotive parts. After the external laser welding machine is started, the workpiece is welded through the welding head 31.
