The lower end of the buffer module is provided with a lifting screw hole. The rotating cavity 26 is located at the bottom of the base 1. The bottom wall of the rotating cavity 26 is rotatably connected to the first threaded rod 2 through a bearing. The first threaded rod 2 is located in the rotating cavity 26 and is interference-fitted with a second bevel gear 5. The base 1 is rotatably connected to the spline shaft 3 through a bearing. One end of the spline shaft 3 located in the rotating cavity 26 is interference-fitted with a first bevel gear 4, and the first bevel gear 4 is meshed with the second bevel gear 5. The rising column 6 is driven up and down by the first threaded rod 2.

[0026] In one embodiment, Figure 1 As shown, the buffer module includes a push slot 14 provided at the lower end of the rising column 6, a push column 11 is slidably provided in the push slot 14, the upper end of the push column 11 is connected to the top wall of the push slot 14 through a first spring 15, and the first threaded rod 2 is threadedly connected to the push column 11. By providing the buffer module, when installing the support frame, the pressure of the rising column 6 on the push column 11 can be effectively reduced, reducing the excessive loss of the first threaded rod 2 under the pressure.

[0027] In one embodiment, Figure 1 As shown, the stabilizing assembly includes a pressure block 7, a second threaded rod 8, a support block 9, and a rotating block 10. Four support blocks 9 are fixedly connected to the lower surface of the support plate 12, wherein two support blocks 9 located on the same side are commonly threadedly connected to the second threaded rod 8, one end of the second threaded rod 8 close to the rising column 6 is fixedly connected to the rotating block 10, and one end of the second threaded rod 8 away from the rising column 6 is fixedly connected to the pressure block 7.

The second spring 20 is fixedly connected between the first limit block 19 and the base 1. The side wall of the first limit block 19 close to the second spring 20 is rotatably connected to the moving rod 21 through a bearing. Two opposite limit grooves 13 are opened on the side wall of the base 1 away from the opening, and the second limit block 23 is slidably connected in the limit groove 13. The moving rod 21 penetrates the base 1 and extends into the limit groove 13 and is fixedly connected to the second limit block 23. The side wall of the second limit block 23 away from the moving rod 21 is fixedly connected with the pull ring 18, and the side walls on both sides of the rising column 6 are provided with a number of buckle grooves 22 corresponding to the first limit block 19. The first limit block 19 cooperates with the buckle groove 22 for one-way locking, providing a certain support and stability to the rising column 6, thereby preventing the first threaded rod 2 from being damaged by excessive pressure from above during construction.

[0029] In one embodiment, Figure 2 As shown, the receiving assembly includes a receiving groove 24, a spline sleeve 17, and a rotating handle 16. The receiving groove 24 is arranged on the right side of the rotating cavity 26. The spline sleeve 17 is slidably connected in the receiving groove 24.

Through the cooperation of the spline sleeve 17 and the spline shaft 3, the rotating handle 16 can be inserted into the receiving groove to prevent the rotating handle 16 from being touched during construction, causing the height of the support frame to change, causing hazards such as tilting and collapse, and protecting the personal safety of the construction workers. Example

[0030] In one embodiment, Figure 1 As shown, the thread lead angle of the first threaded rod 2 is smaller than the equivalent friction angle of the spiral pair formed by the first threaded rod 2 and the push column 11, so that the first threaded rod 2 achieves a self-locking effect.

[0031] In one embodiment, Figure 3 As shown, the height of the second limiting block 23 is greater than the width of the limiting groove 13 , so that the second limiting block 23 can be stuck outside the limiting groove 13 .

[0032] In the utility model, the rotating handle 16 is rotated, the rotating handle 16 drives the spline shaft sleeve 17 to rotate, the spline shaft sleeve 17 drives the spline shaft 3 to rotate, the spline shaft 3 drives the first bevel gear 4 to rotate, the first bevel gear 4 drives the second bevel gear 5 to rotate, the second bevel gear 5 drives the first threaded rod 2 to rotate, the first threaded rod 2 drives the push column 11 to rise and fall, the push column 11 drives the rising column 6 to rise and fall, the rising column 6 drives the support plate 12 to rise and fall, when the support plate 12 reaches the required height, the rotating block 10 is rotated, the rotating block 10 drives the second threaded rod 8 to move to both sides, so that the support frame is fixed. When the installation is completed, the rotating handle 16 can be pushed into the storage groove 24 to prevent the height of the support frame from changing due to touching the rotating handle 16 during construction. When the support frame needs to be recovered, first pull the pull ring 18 to pull the second limit block 23 out of the limit groove 13, and then rotate it 90 degrees so that the second limit block 23 can be stuck outside the limit groove 13. The second limit block 23 drives the moving rod 21 to move, and the moving rod 21 drives the first limit block 19 to move, so that the first limit block 19 leaves the buckle groove 22, and then turn the rotating handle 16 to lower the rising column 6 to complete the recovery.
