[0002] The pin is an important component of the excavator, mainly used to connect and fix various parts of the excavator, such as the arm, dipper arm, etc. The pin is usually made of high-strength alloy steel, and has the characteristics of wear resistance, corrosion resistance and high temperature resistance. It can withstand the huge pressure and impact force of the excavator during operation. The excavator pin needs to be drilled to connect other parts or fix accessories. Before drilling the excavator pin, it is necessary to use a clamp to fix the pin to avoid the pin from shifting during drilling. However, most of the excavator pin drilling fixtures in the prior art still have problems that need to be solved during use.

[0003] Most of the excavator pin shaft drilling fixtures in the prior art require workers to manually adjust the driving handle to provide power to enable the fixture to move closer to the pin shaft when fixing the pin shaft. This method is only suitable for one-time processing of a single pin shaft. When performing large-scale processing, manual operation is inefficient, time-consuming and labor-intensive, and will have a negative impact on the efficiency of the processing work. Therefore, it is necessary to design an excavator pin shaft drilling fixture to solve the above problems. Utility Model Content
