[0002] The bucket teeth of an excavator are important parts of the excavator. They are similar to human teeth and are also vulnerable parts. They are composed of a tooth seat and a tooth tip, which are connected by a pin. During the use of the excavator, the tooth tip of the bucket teeth will be worn due to the large impact. When the tooth tip of the bucket teeth is severely worn, the tooth tip needs to be replaced.

[0003] When the tooth tip of the bucket tooth is subjected to a large impact, the pin located at the tooth tip will be impacted and the pin will be bent. After the two ends of the pin are bent, it is not easy to knock it out from the connecting hole, which makes it inconvenient to remove the tooth tip. When removing the tooth tip from the tooth seat, the pin connecting the tooth seat and the tooth tip needs to be removed. However, when removing the pin, it is necessary to use a tool to forcefully knock the pin out of the connecting hole to disconnect the connection between the old tooth tip and the bucket tooth, and then remove the old tooth tip from the tooth seat. At the same time, when installing the new tooth tip on the tooth seat, it is also necessary to use a tool to forcefully knock the pin into the connecting hole. This tooth tip replacement process is time-consuming and labor-intensive, which greatly increases the workload of the operator.

[0004] Based on this, it is necessary to provide an excavator bucket tooth connection assembly. Utility Model Content
