[0012] Preferably, the adjusting rod is threadedly connected to the support sleeve, and the outer wall of the adjusting rod is threaded.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model provides a tight fit between the fixed sleeve and the high-performance rubber sleeve. When using the device, the fixed sleeve and the high-performance rubber sleeve work together to achieve a flexible connection and buffer function, without exerting excessive binding force on the oil well pipe body. This achieves a flexible connection and avoids internal stress caused by the limited expansion and contraction of the oil well pipe body due to rigid connection. When the formation creeps or the mining operation generates vibration, the high-performance rubber sleeve can absorb and disperse this vibration energy, minimizing the impact of vibration on the oil well pipe body. Its elastic deformation capacity can effectively buffer the impact force brought by vibration, preventing fatigue damage and cracking of the oil well pipe body due to frequent vibration. Through the synergistic work of the fixed sleeve and the high-performance rubber sleeve, a reliable flexible connection and buffer protection are provided for the oil well pipe body, ensuring the safe and stable operation of oil well mining, effectively extending the service life of the oil well pipe body, and reducing maintenance costs and production interruption risks caused by pipeline connection problems.

[0015] 2. This utility model uses adjusting rods to provide threaded adjustment for the support sleeve. In mountainous or hilly areas with uneven terrain, the support sleeve may not be able to make direct and stable contact with the ground. It is necessary to flexibly adjust the extension length of the adjusting rods at different positions according to the unevenness of the terrain. By repeatedly measuring and adjusting the length of each adjusting rod, it is ensured that the fixed platform remains level on complex terrain. Then, the adjusting rods are locked to the support sleeve. If the fixed platform tilts due to foundation settlement, it can be finely adjusted again using the adjusting rods to restore the level of the fixed platform. Finally, the adjusting rods are locked using anti-loosening bolts, which increases the practicality of the device. Attached Figure Description
