The torque pressure-resistant assembly includes a protective sleeve 3 located outside the torsion bar polishing rod 1, and a plurality of support rods 7 are evenly and fixedly connected to the inner side of the protective sleeve 3. A mounting sleeve 4 is threadedly connected to the upper side of the outer side of the protective sleeve 3, and a connecting ring 5 is fixedly connected to the top of the mounting sleeve 4. The outer sides of the support rods 7 are respectively and correspondingly slidably connected to the inner sides of the limiting grooves 6, and the inner side of the connecting ring 5 is threadedly connected to the outer upper side of the torsion bar polishing rod 1.

[0024] The multiple support rods 7 on the inner side of the protective sleeve 3 are respectively nested in the inner side of the limiting groove 6, and the protective sleeve 3 is pressed downward, so that the protective sleeve 3 is sleeved on the outside of the torsion bar polishing rod 1. At this time, the outer side of the mounting pad 14 fits the inner side of the protective sleeve 3 to increase the friction force on the protective sleeve 3. When the bottom end of the protective sleeve 3 contacts the top end of the supporting ring 2, the inner side of the connecting ring 5 is sleeved on the outside of the torsion bar polishing rod 1. When the connecting ring 5 and the mounting sleeve 4 contact the external thread of the torsion bar polishing rod 1 and the external thread of the protective sleeve 3 respectively, the protective sleeve 3 is fixed to the outside of the torsion bar polishing rod 1. When the torsion bar polishing rod 1 rotates, the rotational force generated by the torsion bar polishing rod 1 is transmitted to the outside of the support rod 7 through the limiting groove 6, thereby reducing the force and ensuring stability, thereby further ensuring the torque resistance of the polishing rod itself and improving the service life of the polishing rod.

[0025] Reference Figure 1 and Figure 4The auxiliary rotation assembly includes a plurality of mounting notches 8 located around the outside of the mounting circular groove 13, a fixed disc 9 is nested inside the mounting circular groove 13, and a plurality of driving blocks 12 are evenly fixedly connected around the outside of the fixed disc 9.

The outside of the driving blocks 12 are respectively nested in the inside of the mounting notches 8, and the top of the connecting sleeve 10 is attached to the bottom end of the fixed disc 9.

[0026] The fixed disc 9 and the driving block 12 are respectively nested in the mounting circular groove 13 and the mounting notch 8, and the mounting disc 11 is fitted to the bottom of the torsion bar polishing rod 1. The outer part of the connecting sleeve 10 contacts the inner thread of the mounting circular groove 13, and the connecting sleeve 10 moves upward, thereby pushing the fixed disc 9 upward to fix it. When the torsion bar polishing rod 1 rotates, the driving block 12 further provides the force for rotation, thereby ensuring the rotation rate. When the outer part of the polishing rod rotates, the rotation rate generated on the object will not be lost too much, further ensuring the stability of the rotation.

At this time, the outer side of the mounting pad 14 fits on the inner side of the protective sleeve 3 to increase the friction force on the protective sleeve 3. When the bottom end of the protective sleeve 3 contacts the top end of the supporting ring 2, the inner side of the connecting ring 5 is sleeved on the outside of the torsion bar polishing rod 1. When the connecting ring 5 and the mounting sleeve 4 contact the external threads of the torsion bar polishing rod 1 and the external threads of the protective sleeve 3 respectively, the protective sleeve 3 is fixed to the outside of the torsion bar polishing rod 1. When the torsion bar polishing rod 1 rotates, the rotational force generated by the torsion bar polishing rod 1 is transmitted to the outside of the support rod 7 through the limit groove 6, thereby reducing the force and ensuring stability. The fixed disc 9 and the driving block 12 are respectively nested in the inside of the mounting circular groove 13 and the mounting notch 8, and the mounting disc 11 is fitted to the bottom of the torsion bar polishing rod 1. The outside of the connecting sleeve 10 contacts the inner thread of the mounting circular groove 13, and the connecting sleeve 10 moves upward, thereby pushing the fixed disc 9 upward for fixing. When the torsion bar polishing rod 1 rotates, the driving block 12 further provides a force for rotation, thereby ensuring the rotation rate.
