[0002] The operating lever handle usually consists of components such as a handle rod, a pilot valve, and hydraulic pipelines. The handle rod is the part directly held by the operator. By pushing, pulling, or rotating the handle rod, the opening size and direction of the pilot valve can be changed, thereby controlling the flow direction and pressure of the hydraulic oil, and further driving the movement of each actuator of the drilling rig (such as a rotary motor, a lifting cylinder, a telescopic cylinder, etc.); for the operating handle of a rotary drilling rig, a fiber plastic sleeve is sleeved and installed outside the operating lever. The fiber plastic sleeve is treated with wrinkles to facilitate following the rotation angle of the operating lever. However, the lifespan of the fiber plastic is limited. After long-term use, it splits, which is not conducive to long-term use. It is necessary to strengthen the structure, add a disassembly function for convenient use, replace the support of the fiber plastic with other structures, and extend the service life.

[0021] An embodiment of this application discloses an operating handle for a rotary drilling rig. Referring to Figure 1 and Figure 3 , it includes an operating rod 1. A linkage block 2 is threadedly connected to the outer side of the operating rod 1. Two connecting blocks 3 are fixedly connected to the four sides of the linkage block 2. A first rotating rod 4 is threadedly connected to one side of the connecting block 3. One end of the first rotating rod 4 penetrates through the outer side of the connecting block 3 and is connected to a telescopic rod 5. Nuts 6 are threadedly connected to both ends of the telescopic rod 5, and the nuts 6 are located on one side of the connecting block 3. One end of the telescopic rod 5 is rotatably connected to a second rotating rod 7, and a connecting block 8 is sleeved on the outer side of the second rotating rod 7. When the operating handle needs to be used, by shaking the operating rod 1, the operating rod 1 deflects, and the rotating ball 14 rotates around the sensing rotating groove of the mounting seat. The telescopic rod 5 on the deflected side of the operating rod 1 contracts, and the other three telescopic rods 5 all extend to varying degrees. The telescopic rod 5 rotates around the first rotating rod 4 and the second rotating rod 7 of the connecting block 3 and the connecting block 8, achieving the functions of a stable structure and convenient operation.

[0022] Referring to Figure 1 and Figure 3 , one end of the second rotating rod 7 penetrates through the outer side of the connecting block 8 and is connected to the telescopic rod 5. One end of the second rotating rod 7 penetrates through the outer side of the telescopic rod 5 and is connected to another connecting block 8. Nuts 2 are threadedly connected to the outer sides of both ends of the second rotating rod 7 located on the outer side of the connecting block 8. When disassembly is required, the linkage block 2 moves along the outer side of the operating rod 1, the linkage block 2 is rotated and fixed to the operating rod 1, then the first rotating rod 4 passes through the connecting block 3 and the telescopic rod 5. The first rotating rod 4 located on the outer side of the connecting block 3 rotates along the outer side of the first rotating rod 4 through the nut 6, and then by rotating the telescopic rod 5, the bottom end of the telescopic rod 5 is located between the two connecting blocks 8. Then the second rotating rod 7 passes through the connecting block 8, the telescopic rod 5, and another connecting block 8. The second rotating rod 7 is located on one side of the connecting block 8, and the nut 2 rotates along the outer side of the second rotating rod 7 to fix the telescopic rod 5.

[0023] Referring to Figure 5 , a mounting plate 9 is fixedly connected to the bottom surface of the connecting block 8. A mounting ring 10 is fixedly connected to the bottom surface of the mounting plate 9. Four card slots are opened on the bottom surface of the mounting ring 10.

The main control handle is provided with control buttons and a rocking rod for operating the rotary drilling rig. When the operating rod 1 is rocked, the rotating ball 14 also rotates accordingly, facilitating gear shifting and other operations.

[0027] The implementation principle of an operating handle of a rotary drilling rig in an embodiment of the present application is as follows: First, when disassembly is required, the linkage block 2 moves along the outside of the operating rod 1, rotates the linkage block 2 to fix it to the operating rod 1, then passes the first rotating rod 4 through the first connecting block 3 and the telescopic rod 5. The first rotating rod 4 located outside the first connecting block 3 rotates along the outside of the first rotating rod 4 through the first nut 6, and then rotates the telescopic rod 5 so that the bottom end of the telescopic rod 5 is located between the two second connecting blocks 8. Then, pass the second rotating rod 7 through the second connecting block 8, the telescopic rod 5, and another second connecting block 8. The second rotating rod 7 is located on one side of the second connecting block 8, and the second nut rotates along the outside of the second rotating rod 7 to fix the telescopic rod 5. Secondly, the clamping block 11 is inserted into the card slot of the mounting ring 10, then the screw 12 passes through the mounting ring 10 and is connected to the clamping block 11 and rotated. Then, the bottom surface of the clamping block 11 is inserted into the external mounting seat, the fixing rod 13 passes through the mounting plate 9 and is connected to the external mounting seat, and is connected and rotated. Finally, when the operating handle needs to be used, by rocking the operating rod 1, the operating rod 1 deflects, the rotating ball 14 rotates around the sensing rotating groove of the mounting seat, the telescopic rod 5 on the side where the operating rod 1 deflects contracts, and the other three telescopic rods 5 all extend to varying degrees. The telescopic rod 5 rotates around the first rotating rod 4 and the second rotating rod 7 of the first connecting block 3 and the second connecting block 8, achieving the functions of a stable structure and convenient operation.
