[0002] Oil is mainly used as fuel, gasoline and some chemical industrial products. With the continuous development of the times, there are more and more car users, and the consumption of oil is also increasing. The number of machines for oil exploration and mining is also increasing. When conducting exploration and mining operations, some parts need to be clamped for replacement and use, and the demand for clamping tools is also increasing.

[0003] In the process of clamping the drilling rod, the existing clamping tools generally use two arc-shaped clamping plates to clamp and fix from both sides of the clamping part at the upper end of the drilling rod. This form of clamping causes the drilling rod to move in the vertical direction when in use, thereby causing the clamping stability to decrease, affecting the normal use of the drilling rod. In addition, the existing quick clamping tools can generally only clamp the drilling rod from one direction, and have low flexibility. Therefore, the utility model proposes a quick clamping tool for petroleum machinery to solve the deficiencies in the prior art. Utility Model Content
