Bearing seat and electric tool

The utility model discloses a bearing seat and an electric tool, the bearing seat is used for interference installation of a bearing, the bearing seat comprises a base, an installation part and a supporting part, an assembling space matched with the bearing is arranged in the base, the installation part is arranged in the assembling space, and the installation part and the bearing are in an interference fit assembling relation; the supporting part is arranged on the mounting part and comprises a plurality of flexible cantilevers arranged around the bearing. According to the scheme, the grooves are formed in the two sides of the supporting part, namely the multiple flexible cantilevers, so that the flexible cantilevers can partially fall into the grooves in the two sides when a bearing is assembled, the influence of the size of the flexible cantilevers on the bearing seat is reduced, the structural design is easy to achieve compared with other cantilever type structures, and the manufacturing cost is reduced.
