The restraining rod 8 passes through the connecting plate 2, the fixing plate 3 and the driven plate 4 respectively.

[0032] It should be noted that the fixing sleeve is used to fix the constraint rod 8, ensuring the stability and reliability of the constraint rod 8 and preventing it from loosening or shifting during use. The constraint rod 8 penetrates the connecting disk 2, the fixed disk 3 and the driven disk 4 respectively, playing the role of fixing and restraining, ensuring that these components maintain a relatively stable position relationship during the adjustment process and preventing them from shifting or deforming due to force. The fixed disk 3 and the driven disk 4 penetrate each other to play the role of fixing and restraining.

[0033] In this embodiment, a release spring 9 is directly fixedly connected between the connecting plate 2 and the fixing plate 3 , and the release spring 9 is sleeved on the anchor rod 1 .

[0034] It should be noted that when the adjusting mechanism adjusts the distance between the driven disk 4 and the fixed disk 3, the release spring 9 can provide a certain buffering effect to reduce the damage to the adjusting mechanism caused by sudden force. At the same time, the elastic force of the release spring 9 can also help maintain the stability of the steel cage to a certain extent.

[0035] In this embodiment, eight steel bars 10 arranged in a circular shape are disposed on the periphery of the anchor rod 1 , and a plurality of vertically distributed outer rings 11 are fixedly mounted on both ends of the outer wall of the steel bars 10 .

[0036] It should be noted that the steel bars 10 and the outer ring 11 together constitute the main structure of the steel cage.

[0037] Example 2

[0038] The adjustment mechanism includes eight fixed seats 5 arranged in a circle at the bottom of the driven disk 4 and the fixed disk 3. The middle of the fixed seats 5 is rotatably connected to a first rotating rod 6. The first rotating rod 6 is provided with a connecting rod 7 at one end close to the outer edge of the driven disk 4 and the fixed disk 3.

[0039] In this embodiment, eight circular notches are formed on the outer edge of the outer wall of the fixed plate 3 , and two connecting plates 12 are fixedly mounted on one end of the steel bar 10 close to the fixed plate 3 and the driven plate 4 .

[0040] It should be noted that the connecting plate 12 enables the steel bar 10 to move along with the rotation of the second rotating rod 13, thereby achieving adjustment of the diameter of the steel cage.

[0041] In this embodiment, a second rotating rod 13 is rotatably connected between the two connecting plates 12 on each steel bar 10 , and one end of the connecting rod 7 away from the fixing seat 5 is connected to the second rotating rod 13 .

[0042] It should be noted that the rotation of the second rotating rod 13 can accurately control the position of the steel bar 10, ensuring the accurate adjustment of the diameter of the steel cage.

[0043] To sum up, the variable diameter steel cage expansion anchor rod can realize flexible adjustment of the steel cage diameter by setting the adjustment mechanism and the mutual cooperation of the anchor rod mechanism and other components, as well as the connecting rod 7 that can be conveniently disassembled and adjusted on the first rotating rod 6 and the second rotating rod 13, thereby improving the adaptability and stability of the anchor rod 1 and facilitating the replacement and disassembly of the steel cage. At the same time, by setting the fixing sleeve and the constraint rod 8, the connecting plate 2, the fixed plate 3 and the driven plate 4 are penetrated and fixed, thereby ensuring the stability and reliability of the entire anchor rod mechanism. Moreover, the release spring 9 connected between the connecting plate 2 and the fixed plate 3 can provide a certain buffering effect during the adjustment process, protect the adjusting mechanism from damage, and facilitate the use of the user.
