The staff rotates the rotating shell 3, and the rotating shell 3 makes the end of the arc-shaped top block 8 with a higher arc line press against the extrusion block 5, so that the extrusion block 5 drives the insertion rod 6 to be inserted into the slot 7, so that the sucker rod body 2 is fixed inside the self-lubricating wear-resistant joint body 1, so that the staff can connect the self-lubricating wear-resistant joint body 1 and the sucker rod body 2.

[0023] Reference Figure 1 - Figure 5 As shown, in this embodiment: slide grooves 9 are provided on both sides of the inner wall of the adjustment groove 4, and sliders 10 are fixedly connected on both sides of the extrusion block 5. The surface of the slider 10 is slidably connected to the inside of the slide groove 9. When the staff moves the extrusion block 5, the extrusion block 5 drives the slider 10 to slide inside the slide groove 9. Through the above arrangement, the stable movement of the extrusion block 5 is achieved, and the flexibility of operation is guaranteed. The close fit between the slider 10 and the slide groove 9 effectively reduces the friction and improves the service life of the overall device.

[0024] Reference Figure 1 - Figure 5 As shown, in this embodiment: the size of the rod 6 is adapted to the size of the slot 7, and the surface of the rod 6 is plugged into the interior of the slot 7. By carefully designing the size of the rod 6 to be adapted to the size of the slot 7, the size matching between the rod 6 and the slot 7 is ensured, so that the rod 6 can be tightly inserted into the interior of the slot 7, thereby ensuring that the connection between the two is extremely stable.

[0025] Reference Figure 1 - Figure 5 As shown, in this embodiment: the side of the extrusion block 5 close to the slot 7 is fixedly connected with a storage spring 11, and the side of the storage spring 11 close to the slot 7 is fixedly connected to the inside of the adjustment slot 4. When the staff rotates the rotating shell 3 to squeeze the extrusion block 5 to move, the extrusion block 5 squeezes the storage spring 11 to compress and store force, and drives the insertion rod 6 to be inserted into the slot 7 for fixation. When the staff rotates the rotating shell 3 to cancel the abutment between the arc-shaped top block 8 and the extrusion block 5, the storage spring 11 rebounds quickly and pushes the extrusion block 5, so that the insertion rod 6 releases the limit between the slot 7, so that the staff can disassemble the self-lubricating wear-resistant joint body 1 and the sucker rod body 2.

[0026] Reference Figure 1 - Figure 5 As shown, in this embodiment: both ends of the self-lubricating wear-resistant joint body 1 are provided with an annular groove 12, and the inner wall of the rotating shell 3 is fixedly connected with a ring block 13, and the surface of the ring block 13 is slidably connected to the inside of the annular groove 12. When the staff rotates the rotating shell 3, the rotating shell 3 drives the ring block 13 to rotate inside the annular groove 12. Through the above arrangement, the stability and durability of the joint during operation are guaranteed. The matching design between the annular groove 12 and the ring block 13 not only reduces friction and extends service life, but also reduces maintenance costs to a certain extent. In addition, this structural design also allows the joint to maintain a good working condition under certain pressure and impact, thereby ensuring the reliability of the entire system.

[0027] Reference Figure 1 - Figure 5 As shown, in this embodiment: a sealing gasket 14 is installed on the side of the inner wall of the self-lubricating wear-resistant joint body 1 close to the sucker rod body 2. By installing a sealing gasket 14 on the side of the inner wall of the self-lubricating wear-resistant joint body 1 close to the sucker rod body 2, direct friction between the sucker rod body 2 and the inner wall of the self-lubricating wear-resistant joint body 1 can be effectively prevented, thereby extending the service life of the sucker rod body 2.

[0028] Reference Figure 6 As shown, in this embodiment: a threaded rod 15 is provided at the front end of the rotating shell 3, and a threaded hole 16 is opened on the side of the sucker rod body 2 close to the threaded rod 15. In order to prevent the rotating shell 3 from shifting during operation, the staff aligns the threaded rod 15 with the threaded hole 16 and rotates it so that the threaded rod 15 is inserted into the threaded hole 16 to fix the rotating shell 3, so that the position of the rotating shell 3 will not shift.

[0029] Working principle: The staff rotates the rotating shell 3, and the rotating shell 3 makes the end of the arc-shaped top block 8 with a higher arc line press against the extrusion block 5, so that the extrusion block 5 drives the insertion rod 6 to be inserted into the slot 7, so that the sucker rod body 2 is fixed inside the self-lubricating wear-resistant joint body 1, so that the staff can connect the self-lubricating wear-resistant joint body 1 and the sucker rod body 2. When the staff moves the extrusion block 5, the extrusion block 5 drives the slider 10 to slide inside the slide groove 9. Through the above arrangement, the stable movement of the extrusion block 5 is achieved, while the flexibility of operation is guaranteed, and the close fit between the slider 10 and the slide groove 9 is guaranteed. , effectively reducing friction and improving the service life of the entire device. By carefully designing the size of the plug rod 6 to match the size of the slot 7, the size matching between the plug rod 6 and the slot 7 is ensured, so that the plug rod 6 can be tightly inserted into the interior of the slot 7, thereby ensuring that the connection between the two has extremely high stability. When the staff rotates the rotating shell 3 to squeeze the squeezing block 5 to move, the squeezing block 5 squeezes the storage spring 11 to compress and store force, and drives the plug rod 6 to be inserted into the slot 7 for fixation. When the staff rotates the rotating shell 3 to cancel the abutment between the arc-shaped top block 8 and the squeezing block 5, the storage spring 11 rebounds quickly and pushes the extrusion block 5, so that the insertion rod 6 releases the limit between the slot 7, so that the staff can disassemble the self-lubricating wear-resistant joint body 1 and the sucker rod body 2. When the staff rotates the rotating shell 3, the rotating shell 3 drives the ring block 13 to rotate inside the ring groove 12. Through the above arrangement, the stability and durability of the joint during operation are timely guaranteed. The matching design between the ring groove 12 and the ring block 13 not only reduces friction and prolongs service life, but also reduces maintenance costs to a certain extent. In addition, this structural design also allows the joint to withstand certain pressure and In the event of impact, it still maintains a good working condition, ensuring the reliability of the entire system. The sealing gasket 14 is installed on the side of the inner wall of the self-lubricating wear-resistant joint body 1 close to the sucker rod body 2, which can effectively prevent the sucker rod body 2 from directly rubbing against the inner wall of the self-lubricating wear-resistant joint body 1, thereby extending the service life of the sucker rod body 2. In order to prevent the rotating shell 3 from shifting during operation, the staff aligns the threaded rod 15 with the threaded hole 16 and rotates it, so that the threaded rod 15 is inserted into the threaded hole 16 to fix the rotating shell 3, so that the position of the rotating shell 3 will not shift.
