[0002] When conducting trial construction of a building, the foundation must first be treated. Excavators can efficiently remove soil from the ground, reducing the labor pressure on workers and greatly improving construction efficiency.

[0003] Common excavators use a boom to drive the bucket for digging. In most excavators, the bucket is bolted to the boom. Disassembling the bucket for maintenance is cumbersome and inconvenient. Furthermore, during operation, the bucket's contact with the ground, impacts, and movement generate vibrations, which can loosen the bolts over time, affecting equipment operation. Additionally, the bucket carries soil during excavation, creating dust that impacts the work area and affects workers. Moreover, during excavation, the boom and bucket rotate under the excavator's drive. If workers accidentally enter the boom's range of motion, the operator, focused on the front, may miss them, and the powerful boom and bucket could strike them, causing injury. Utility Model Content
