The dust cover 12 is installed inside the round opening. When it is necessary to adjust the distance between the moving base 12 and the moving base 23, first remove the dust cover 16. Then, use a wrench to insert into the actuating block 424 and rotate it. The actuating block 424 drives the rotation of the bevel gear 423 through the actuating column 422, which in turn drives the rotation of the bevel gear 421. This then drives the rotation of the transverse column 411 and its own worm gear 412. The worm gear 412 then drives the rotation of the worm wheel 414, which in turn drives the rotation of the connecting rod 413. This drives the movement of the two sets of sliding bars 13, thus adjusting the distance between the moving base 12 and the moving base 23. Then, replace the dust cover 16. When it is necessary to adjust the distance between the two sets of transverse bases 5,Simply pull the two sets of transverse bases 5 together, moving them away from or towards each other. After moving them to the appropriate position, use bolts to install them inside the threaded cylinder 85 and press the positioning tooth block 81 to move. The positioning tooth block 81 then inserts into the toothed groove on the sliding strip 10, locking the position of the sliding strip 10. This allows for the separate movement of the moving bases 2 and 3, enabling adjustments based on the width of the modular building. This makes the structure suitable for modular buildings of different widths, and its good self-locking effect prevents displacement, enhancing its mobility. Furthermore, the distance between the left and right sets of transverse bases 5 can be adjusted, allowing the structure to be used in modular buildings of different lengths with easy adjustment, further improving its applicability and practicality.

[0023] The positioning structure 8 includes a positioning toothed block 81, a rectangular block 82, a spring 83, a connecting rod 84, and a threaded cylinder 85. The sliding bar 10 has two sets of toothed grooves arranged equidistantly from left to right. The positioning toothed block 81 is slidably installed inside the U-shaped mounting plate 7. The U-shaped mounting plate 7 has two sets of square cavities distributed vertically. The rectangular block 82 is slidably installed inside the square cavity. The spring 83 is fixedly installed between the rectangular block 82 and the inner wall of the square cavity. One end of the connecting rod 84 is fixedly connected to the positioning toothed block 81, and the other end of the connecting rod 84 extends into the square cavity and is fixedly connected to the rectangular block 82. The U-shaped mounting plate 7 has a through hole, and the threaded cylinder 85 is fixedly installed on the inner wall of the through hole. The snap-fit ​​pad 11 on the modular house 21 is inserted into the bearing base 6. Then, by holding the lever 95 and turning the transmission rod 94 and the double-acting screw 91, the two sets of sliding seats 92 are brought closer together. Then, the L-shaped insert 93 is inserted into the positioning groove on the snap-fit ​​pad 11 and the connection is completed. Then, the dust cover 12 is put back on. The modular house 21 can be quickly and conveniently connected to the structure. Compared with the method of using multiple bolts to connect it, it avoids the inconvenience caused to the user by the cumbersome and laborious connection process. Moreover, the subsequent separation does not require the removal of multiple bolts, making it easier to assemble and separate, and facilitating the subsequent dismantling operation, thus enhancing the practicality of the structure.

[0024] Working principle: When adjusting the distance between movable seat 1 (2) and movable seat 2 (3), first remove dust cover 2 (16). Then, insert a wrench into the actuating block 424 and rotate it. The actuating block 424 drives the rotation of bevel gear 2 (423) through the actuating column 422, which in turn drives the rotation of bevel gear 1 (421). This, in turn, drives the rotation of the transverse column 411 and its own worm gear 412. The worm gear 412 then drives the rotation of the worm wheel 414, which in turn drives the rotation of the connecting rod 413. This, in turn, drives the movement of the two sets of sliding bars 2 (13) to adjust the distance between movable seat 1 (2) and movable seat 2 (3). Then, replace the dust cover 2 (16) and adjust the two sets of transverse sliding bars. When adjusting the distance between the bases 5, simply pull the two sets of transverse bases 5 to move them away from or closer to each other. After moving them to the appropriate position, use bolts to install them inside the threaded cylinder 85 and press the positioning tooth block 81 to move. Then, the positioning tooth block 81 inserts into the toothed groove on the sliding strip 10, which locks the position of the sliding strip 10. Then, insert the snap-fit ​​pad 11 on the modular house 21 into the bearing base 6. Then, hold the lever 95 and turn the transmission rod 94 and the double-acting screw 91 to rotate. This will drive the two sets of sliding seats 92 to move closer to each other. Then, the L-shaped insert 93 is inserted into the positioning groove on the snap-fit ​​pad 11 and the connection is completed. Then, put the dust cover 12 back on.
