Description

technical field [0001] The invention relates to a wrench, in particular to a ratchet wrench with a detachable sleeve and can be stored in a handle. Background technique [0002] Hand tools play a role in promoting productivity in various societies. Due to the invention and application of screws, bolts and nuts, wrenches have become a pivotal tool in the field of mechanical hand tools. Since the invention of the wrench, various types of wrenches have appeared, such as combination wrenches, open-end wrenches, ring wrenches, socket ratchet wrenches and so on. [0003] In the field of socket wrench technology, due to the different sizes of nuts or screws used in different occasions, the sleeves used to drive these nuts or screws also require different inner diameters to cooperate with them, so there is a kind of The toolbox contains a socket ratchet wrench and a series of sockets with different inner diameters. These sockets can be detachably combined with the socket wrench to ...
