[0002] At present, in the field of loaders in my country, the main traditional models are only equipped with one bucket, which is mainly used for shoveling powdery and small-particle materials such as sand, soil, coal, and ore. However, with the rapid development of various industries such as industry, agriculture, forestry, and mining, the single function of the original loader is far from meeting the actual needs of users. It is necessary to invent a loader with multiple functions. The key to solving the problem is to invent a simple and convenient quick-change device for buckets and shovels, which can fundamentally solve this problem. For this reason, we designed and invented a loader quick-change working device, which solves the problem of multiple functions for users and saves them a lot of money. It is very popular with users and has a very promising market prospect. Utility Model Content
