[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1 to 4 , the present utility model provides a technical solution:

[0022] A driving rod for a rotary drilling rig console, comprising a console 3 and a driving rod 1. The driving rod 1 is installed on the console 3. A grip 4 is provided at the upper end of the driving rod 1. A circular groove matching the driving rod 1 is opened at the bottom of the grip 4. The inside of the driving rod 1 is a central control structure. Slide holes are opened on both sides of the upper end of the driving rod 1. The driving rod 1 is provided with a locking unit through the slide holes that can lock with the groove wall of the circular groove. The locking unit can adjust the height of the grip 4. An internal thread ring 2 is provided on the outer wall of the rod wall of the driving rod 1. An unlocking mechanism for unlocking the locking unit is provided on the internal thread ring 2. The internal thread ring 2 is screwed down on the thread groove. At the same time, the internal thread ring 2 drives the pull rod 5 to move downward through the limiting rod 8. The pull rod 5 drives two locking blocks 7 to move outside the locking grooves through the connecting rod 6, thereby realizing unlocking. The outer ring wall of the internal thread ring 2 is provided with anti-slip lines, and the anti-slip lines increase the friction on the outside of the internal thread ring 2, facilitating the staff to rotate the internal thread ring 2.

[0023] The locking unit includes two locking blocks 7 and a pull rod 5. A connecting rod 6 is arranged inside the driving rod 1. The two locking blocks 7 are slidably arranged in the two slide holes. Both ends of the locking block 7 extend outside the slide holes. A plurality of locking grooves matching the locking blocks 7 are opened on the groove wall of the circular groove. One end of the two locking blocks 7 facing each other is hinged with a connecting rod 6, and the other end of the connecting rod 6 is hinged with the upper end of the pull rod 5. Chamfers are opened at the ends of the two locking blocks 7 facing away from each other, and the chamfers facilitate the locking blocks 7 to be inserted into the locking grooves. The plurality of locking grooves are arranged at equal intervals.

[0024] The unlocking mechanism includes a limiting rod 8. The rod wall of the driving rod 1 is provided with a thread groove matching the internal thread ring 2. The two limiting rods 8 are respectively fixedly arranged on both sides of the lower end of the pull rod 5. A strip-shaped hole 10 matching the limiting rod 8 is opened on the rod wall of the driving rod 1. An annular groove matching the limiting rod 8 is opened on the inner ring wall of the internal thread ring 2. Round heads 9 are provided at the ends of the two limiting rods 8 facing away from each other, and the round heads 9 reduce the friction between the limiting rods 8 and the annular groove.

[0025] During adjustment, rotate the internal thread ring 2. The internal thread ring 2 screws downward on the thread groove. At the same time, the internal thread ring 2 drives the pull rod 5 to move downward through the limit rod 8. The pull rod 5 drives the two locking blocks 7 to move outside the locking grooves through the connecting rod 6. At this time, the height of the grip 4 can be adjusted. After adjusting to the appropriate height, screw the internal thread ring 2 upward. The internal thread ring 2 drives the pull rod 5 to rise through the limit rod 8. The pull rod 5 drives the two locking blocks 7 to snap into the corresponding locking grooves through the connecting rod 6. The adjustment is completed, which is convenient to adjust the height of the grip 4 according to the height of the operator and improves the comfort of using the driving rod.
