[0019] Furthermore, a handle 16 is fixedly mounted on one side of the splint 15 . The handle 16 is arranged in a U-shaped structure, so that the splint 15 can be adjusted by the handle 16 .

[0020] Furthermore, two limiting plates 17 are fixedly mounted on the top side of the tailor-welded base 1 , and the sides of the two limiting plates 17 that are close to each other fit in with the left outer plate 2 , so as to facilitate limiting the left outer plate 2 .

[0021] In use: During the welding process of the left platform of the medium-sized excavator, the welder adjusts the two handles 16 outward at the same time, so that the two sets of clamps 15 drive the mounting blocks 13 to slide outward in the corresponding mounting grooves 12, so that the two second springs 14 are deformed and compressed under the force. Then, the left outer plate 2 is placed on the welded base 1, so that the left outer plate 2 is inserted into the two limit plates 17, and then the threaded rod 10 is adjusted to rotate in the threaded barrel 9, thereby driving the circular push plate 11 to move rightward to squeeze the left outer plate 2 onto the U-shaped fixing plate 4.
