[0026] Refer to Figures 1-2 , a disk buckle support is fixedly arranged at the bottom end of the bottom plate 1. A chute 16 is formed on the top surface of the slide plate one 6. A fixing block 17 is fixedly arranged at the inner bottom end of the sliding sleeve 7. The fixing block 17 is located in the chute 16. Three-directional balls 18 are inlaid in the fixing block 17. The balls 18 are in contact with the inner side surface of the chute 16. Three-fourths of the volume of the balls 18 is inlaid in the fixing block 17. By controlling the second hydraulic rod 5, the secondary slide plate two 8 having an indirect connection relationship with it is driven to move on the slide plate one 6, and the sliding sleeve 7 generates a displacement on the slide plate one 6. The fixing block 17 at the inner bottom end of the sliding sleeve 7 is located in the chute 16. Three-directional balls 18 are inlaid in the fixing block 17. The designed direction of the balls 18 is three-sided, just corresponding to each inner side surface of the chute 16. The balls roll in the chute 16, ensuring that the moving friction is greatly reduced and the movement is more labor-saving. The designed direction of the balls 18 is three-sided, and there are several balls 18 facing each side.

[0027] Refer to Figure 1 and Figure 3, a secondary chute 19 is provided on the top surface of the secondary slide plate 8.

By controlling the third hydraulic rod 14 to drive the secondary sliding sleeve 9 indirectly connected thereto to move on the secondary slide plate 8, the secondary fixed block 20 at the inner bottom end of the secondary sliding sleeve 9 is located in the secondary chute 19. A three-direction secondary ball 21 is embedded in the secondary fixed block 20. The design direction of the ball 18 is three-sided, just corresponding to each inner side surface of the secondary chute 19. The ball rolls in the secondary chute 19, ensuring that the moving friction is greatly reduced and the movement is more labor-saving. The design direction of the secondary chute 19 is three-sided, and each side-facing secondary chute 19 is several, ultimately comprehensively changing the lateral relative position of the secondary sliding sleeve 9.

[0028] Refer to Figure 1 , four corners of the top end of the bottom plate 1 are fixedly provided with stabilizing cylinders 22, and four corners of the bottom end of the lifting plate 3 are fixedly provided with stabilizing rods 23 inserted into the stabilizing cylinders 22.

The lifting baffle 24 can extend out in the corresponding side baffle 12 and can be selected with different lengths according to the construction conditions to correspond to different required arch rib segments. The driving motor 26 drives the threaded rod 27 to rotate, and the lifting baffle 24 is threadedly sleeved on the threaded rod 27, ultimately driving the lifting and lowering of the lifting baffle 24. In Figure 4 , a vertical chute is provided on one side of the lifting baffle 24, and a small slider penetrating into the vertical chute is fixed on the side baffle 12, aiming to prevent the lifting baffle 24 from rising too much and avoid the lifting baffle 24 rising out of the side baffle 12.

[0030] During specific operation, the lifting plate 3 indirectly connected to the hydraulic rod 1 is driven to move up and down to change the height of the lifting plate 3 in the vertical direction. The secondary slide plate 2 is driven by the hydraulic rod 5 to move on the slide plate 1, and the secondary sliding sleeve 9 is driven by the hydraulic rod 3 to move on the secondary slide plate 2 to comprehensively change the lateral relative position of the secondary sliding sleeve 9.
