Electric planer is a handheld electric tool that is driven by a single-phase series excitation motor through a transmission belt to perform planing operations with a planer. It has the characteristics of high production efficiency, flat and smooth planing surface, etc. Widely used in housing construction, housing decoration, woodworking workshops, outdoor woodworking operations, as well as vehicle, ship, bridge construction and other occasions, for various types of wood plane planing, chamfering, and cutting operations. Electric planers have two types of structures: direct transmission and indirect transmission. The direct drive type is where the planer is directly mounted on the output shaft of the electric motor, while the indirect drive type is where the output shaft of the electric motor drives the cutter shaft through nylon. The electric planer is composed of an electric motor, a knife cavity structure, a planer depth adjustment mechanism, a handle, a switch, and a non rewirable plug. This series of electric planers adopts a double insulation structure. The electric planer shell and handle are integrated with plastic injection molding, and the plastic shell serves as an additional insulation for the stator core and the additional insulation for the rotor core to the ground, forming a dual insulation. The knife cavity structure has two layers: upper and lower, and the upper layer is a chip removal chamber, which is discharged by the cooling air of the electric motor fan. The planing depth adjustment mechanism is composed of an adjustment handle, anti loosening spring, front bottom plate, etc. By twisting the adjustment handle, the front bottom plate moves up and down to adjust the planing depth. The output shaft of the electric motor drives the nylon transmission belt to drive the planer on the cutter shaft for planing operations. The power cord adopts a double core sheathed flexible cable, which forms an integral part with the double column rubber plug and cannot be reconnected
