Description

Switch assembly and electric tool Technical Field The utility model relates to the technical field of electric tools, in particular to a switch assembly and an electric tool. Background The electric tool has the advantages of high efficiency and convenience, is widely applied to the fields of building manufacture, home maintenance, gardening operation and the like, and remarkably improves the production life efficiency. The switch of the electric tool is usually provided with a locking mechanism for locking and unlocking the pressing trigger of the switch, so that safety accidents caused by the fact that a user touches the switch by mistake are avoided. However, in order to realize the press locking and unlocking under the external operation control, the existing switch assembly can introduce a complex linkage structure, the self-locking structure uses a large number of parts, the linkage relationship between the parts is complex, the switch assembly is complex, the structure reliability is low, for example, the translational self-locking structure realizes the translational movement of a locking piece driven by an external operation piece through the linkage of multiple connecting arms, and the stress of the locking piece is unbalanced in the use process, so that the problem of functional failure is easy to occur.
