[0002] A loader is a large-scale engineering machinery widely used for loading and unloading bulk materials such as coal, sand, stone, ore, and building materials. It has the advantages of strong power, high operating efficiency, convenient operation, and maneuverability. The loader shovel tooth is one of the auxiliary tools of the loader. It is usually used at the front end of the loader for digging, shoveling and moving land, sand, gravel, and other materials. It is located at the end of the loader's bucket arm and is fixed to the loader by a clamp or a clamping fixture. During the installation of the existing clamping fixture, the hydraulic system is usually used to clamp the shovel teeth for installation. Due to the different sizes of the shovel teeth, the mismatched hydraulic system can easily cause the shovel teeth to shake or shift during the installation process, reducing the operating accuracy and safety. In addition, hydraulic systems with different shovel tooth sizes need to frequently replace the matching equipment for auxiliary installation during installation, which increases the complexity of the system and reduces the installation efficiency. Therefore, we proposed a loader shovel tooth clamping fixture to solve the above-mentioned problems. Utility Model Content
