The arc-shaped setting is more convenient for clamping and supporting the main body tube 24. Both ends of the clamping plate 4 are hinged with an arc-shaped rotating plate 12 that presses the side of the main body tube 24. The arc-shaped rotating plate 12 can rotate on the clamping plate 4. The center of the arc-shaped inner side of the clamping plate 4 is elastically connected with a limiting plate 11 stuck in the main body tube 24. After the clamping plate 4 and the arc-shaped rotating plate 12 clamp the main body tube 24, the limiting plate 11 limits the main body tube 24 to prevent the main body from being stuck. The tube 24 rotates radially or axially, and positioning guide columns 10 passing through one end of the splint 4 are vertically fixed at both ends of the interior of each mounting tube 3. The splint 4 is limited so that the splint 4 moves along the positioning guide columns 10, and then the first screw 13 is limited. When the first rotating outer tube 5 rotates, the first screw 13 rises and falls, and the two first screws 13 in one mounting tube 3 move in opposite directions. One end of the top surface of each splint 4 is provided with an adjusting member which is meshed with the positioning guide column 10 and drives the arc-shaped rotating plate 12 to rotate.

[0023] In order to realize the simultaneous rotation of multiple first rotating outer tubes 5, the driving member includes a worm 6 rotatably connected between the inner walls on both sides of the prefabricated box body 1 and multiple worm wheels 9 meshingly connected with the worm 6, and the worm 6 is located on the outside of the mounting tube 3, and the multiple worm wheels 9 are respectively fixedly sleeved on the outside of the first rotating outer tube 5, and one end of the worm 6 extends out of the prefabricated box body 1 and is fixedly connected with a handwheel 8. The transmission member 7 includes a sprocket fixedly connected to one end of the worm 6 and a chain connecting the two sprockets. Under the drive of the transmission member 7, any rotation of the two handwheels 8 can drive the two worms 6 to rotate. At the same time, the two handwheels 8 are respectively arranged on both sides of the prefabricated box body 1, and it is convenient to rotate the worm 6 no matter where the prefabricated box body 1 is.

[0024] Reference Figure 2-Figure 3Horizontal ear plates are extended from both ends of the clamp plate 4, and a through hole adapted to the positioning guide column 10 is provided on one side of the top surface of the ear plate to facilitate the clamp plate 4 to slide along the positioning guide column 10.

[0025] In order to realize the elastic setting of the limit plate 11 under the clamping plate 4, a sliding column 22 is fixedly connected to the top surface of the limit plate 11, and the top end of the sliding column 22 passes through the clamping plate 4 and slides in the second screw 19. The second screw 19 is hollow inside, and the lower end of the second screw 19 passes through a square notch, and the second screw 19 can be observed from the notch. The outer side of the sliding column 22 is located at the bottom end of the notch and is fixedly sleeved with a limiting retaining ring 23 to prevent the sliding column 22 from detaching from the second screw 19 under gravity, and a spring 21 is provided above the limiting retaining ring 23 and is sleeved on the outer side of the sliding column 22. Initially, the limiting retaining ring 23 is located at the bottom of the notch. When the limit plate 11 contacts the main body tube 24, it moves upward and compresses the spring 21. Under the rebound of the spring 21, the limit plate 11 contacts the main body tube 24 more closely.

[0026] Reference Figure 3-Figure 5 The adjusting member includes two shaft seats 16 fixed on the ear plate on one side of the through hole, a second rotating outer tube 18 rotatably connected between the two shaft seats 16, and a gear 17 fixedly sleeved on the outside of the second rotating outer tube 18. The gear 17 is located between the two shaft seats 16 and corresponds to the positioning guide column 10. A second screw 19 is threadedly connected inside the second rotating outer tube 18. A connecting rod 20 is connected between one end of the second screw 19 away from the second rotating outer tube 18 and the top surface of the arc-shaped rotating plate 12. The end of the second screw 19 away from the second rotating outer tube 18 is tilted downward so that the second screw 19 is hinged to the top of the connecting rod 20. The bottom end of the connecting rod 20 is hinged to the arc-shaped rotating plate 12, so that when the second screw 19 moves toward the first screw 13, the connecting rod 20 can push the arc-shaped rotating plate 12 to rotate downward. Similarly, when the second screw 19 moves in the opposite direction, the arc-shaped rotating plate 12 rotates upward.

[0027] Reference Figure 5-Figure 6 The upper and lower sides of the positioning guide column 10 are both provided with cutouts 14, the depth of the cutout 14 is the radius of the positioning guide column 10, and a plurality of teeth 15 are arranged in the cutout 14, the plurality of teeth 15 are linearly arranged and form a rack, one end of the gear 17 is inserted into the cutout 14 and meshes with the rack, when the gear 17 is at the top of the rack, it is the initial position, at this time, the main body tube 24 with the maximum diameter can be clamped between the two clamping plates 4, when the two clamping plates 4 move downward, the gear 17 rotates between the two shaft seats 16 due to the meshing with the rack.

[0028] Specifically, when installing the main pipe 24 of the prefabricated building, the prefabricated box 1 is first placed at the installation position of the main pipe 24 and fixed. Then, the main pipe 24 is passed through the installation tube 3 of the prefabricated box 1, and the main pipe 24 is rotated so that the groove position of the main pipe 24 corresponds to the position of the upper and lower limit plates 11 in the installation tube 3. Then, one of the hand wheels 8 is rotated. The rotation of the hand wheel 8 drives the connected worm 6 to rotate, and the other worm 6 is synchronously rotated under the drive of the transmission member 7. The two worms 6 rotate and drive the first rotating outer tube 5 to rotate under the meshing of the worm gear 9. When the first rotating outer tube 5 rotates, the first screw 13 starts to move downward in the first rotating outer tube 5 by the limit of the clamping plate 4 and the positioning guide column 10. The downward movement of the first screw 13 drives the clamping plate 4 to move downward until the clamping plate 4 contacts the surface of the main pipe 24. The upper and lower clamping plates 4 clamp the upper and lower ends of the main pipe 24, and the limit plates 11 are pushed into the groove.

[0029] At the same time, when the splint 4 moves downward, the gear 17 starts to rotate under the meshing of the teeth 15. The rotation of the gear 17 drives the second rotating outer tube 18 to rotate. The rotation of the second rotating outer tube 18 drives the second screw 19 to move toward the first screw 13 along the length direction of the second rotating outer tube 18. The second screw 19 moves and, under the action of the connecting rod 20, drives the arc-shaped rotating plate to rotate around the hinge with the splint 4, so that the arc-shaped splint 4 is tightly attached to both sides of the outer periphery of the main tube 24, further clamping the main tube 24.
