The first rotating shaft 32 is rotatably connected to the inside of the speed reduction box shell 1. The first pinion 33 is engaged with the outside of the first gear 35. The second pinion 36 is engaged with the outside of the second gear 37. The first pinion 33 and the first gear 35 are engaged with each other to reduce the speed by the first step. The second pinion 36 and the second gear 37 are engaged with each other to reduce the speed by the second step. Thus, the speed reduction effect is achieved, and the construction is facilitated.

[0027] When working, the inside of the rotating frame 21 is placed with certain disc springs 214 according to the need. The mounting frame 22 is bolted to the rotating frame 21. The drill rod is inserted into the middle of the mounting frame 22 and the rotating frame 21 to press the disc springs 214. The extending hydraulic telescopic rod 26 is rotated and connected to the polished rod 28 through the rotating block 210.

The clamping blocks 213 clamp and fix the drill rod to achieve the purpose of clamping the drill rod, which facilitates the installation of the drill rod. Then, the motor 31 drives the first rotating shaft 32 to rotate in the inside of the speed reduction box shell 1. The first pinion 33 and the first gear 35 are engaged with each other to rotate the second rotating shaft 34 in the inside of the speed reduction box shell 1. The second pinion 36 and the second gear 37 are engaged with each other to rotate the rotating frame 21 in the inside of the speed reduction box shell 1.

The clamping blocks 213 clamp and fix the drill rod to achieve the purpose of clamping the drill rod, which facilitates the installation of the drill rod. Thus, the problem that the entire installation process is long and the drilling efficiency of the equipment is reduced due to the need to disassemble the rubber barrel shell and replace the slip assembly when installing the drill rod is solved.
