　　1. Introduction
　　The tooth holder is an important digging component equipped on engineering machinery such as excavators and loaders. Careful operation is required during installation to ensure stability and reliability. This article mainly introduces how to install the tooth holder on the bucket lip for reference by engineering machinery users.
　　2. Installation Steps
　　1. Clean the surfaces of the bucket lip and tooth holder
　　Before installation, clean the surfaces of the bucket lip and tooth holder to remove deposits, dust, and other debris, ensuring the surfaces are clean.
　　2. Confirm alignment position
　　Align the tooth holder with the tooth groove on the bucket lip and position it as close as possible to the upper edge of the bucket lip. Verify whether the installation position of the tooth holder is correct.
