By sliding one side of the upper splint 505 in the sliding groove 12 inside the groove 502, the upper splint 505 can slide vertically at the groove 502 toward the lower splint 503.

[0032] refer to Figure 1 The left and right sides of the base plate 1 are symmetrically fixed with mounting blocks 10. The mounting blocks 10 are L-shaped. By using the mounting blocks 10 on the base plate 1, the base plate 1 can be easily installed and fixed.

[0033] refer to Figure 1 The upper end of the first mounting column 2 is fixedly installed with a serpentine tube 7, and the upper end of the serpentine tube 7 is fixedly installed with a lamp 8. The lower end of the first mounting column 2 is fixedly connected with a fixing plate 11, and the fixing plate 11 is fixedly installed on the upper end of the base plate 1 by screws. The serpentine tube 7 on the first mounting column 2 can meet the shape adjustment of the use angle of the lamp 8, and the lamp 8 can also be used to provide good lighting during clamping, docking or welding, making it convenient for the staff to operate.

[0034] Principle and advantages of use: During use, first, two automobile shaft parts are clamped by the clamping mechanisms 5 on the first mounting column 2 and the second mounting column 3 respectively. When fixing the shaft parts, one end of the shaft parts is placed on the V-shaped groove 504 of the lower clamping plate 503 at the groove 502 of the clamping seat 501. Then, the operating handle 507 is rotated to make the stud 506 connected to the handle 507 threaded and retracted on the clamping seat 501. At the same time, the lower end of the stud 506 rotates to push the upper clamping plate 505 to slide toward the lower clamping plate 503. The upper clamping plate 505 and the lower clamping plate 503 cooperate to facilitate the stable clamping and fixing of the shaft parts.

[0035] When docking two fixed shaft parts, the crank handle 907 on the front side of the base plate 1 is used to shake the rotating rod 908 to rotate in the bottom groove 906, so that the second bevel gear 905 on the outside of the rotating rod 908 engages and transmits the first bevel gear 904, and the second screw 902 connected to the first bevel gear 904 can rotate at the mounting hole 901. Due to the rotation of the second screw 902, the moving block 903 connected to the outer thread drives the second mounting post 3 to slide horizontally on the base plate 1 toward the first mounting post 2 until the welding parts of the two shaft parts are docked. Then, when the welding parts of the two shaft parts are docked in size, the crank handle 601 is rotated to make the first screw 603 connected to the crank handle 601 rotate in the mounting groove 602. Due to the rotation of the first screw 603, the adjusting block 604 connected to the outer thread slides and rises and falls in the mounting groove 602, thereby driving the shaft parts fixed by one of the clamping mechanisms 5 to adjust the welding parts of the other fixed shaft parts.
