Abstract

The invention discloses an electric circular saw. The electric circular saw comprises an output shaft, an electric motor and a shell; the output shaft is used for mounting a saw blade; the electric motor is used for driving the output shaft to rotate; and the shell comprises handles which are symmetrical with respect to a first plane. The shell further comprises a first containing part and a combining part, wherein the first containing cavity used for containing an electric motor is formed in the first containing part, and the first containing part comprises a first part arranged on the left side of the first plane and a second part arranged on the right side of the first plane; and the combining part is used for combining a power supply device capable of supplying power to the electric circular saw. Each handle is provided with a first end and a second end located at the two ends in the extending direction of the handle correspondingly, the first containing part is connected to the first end of the handle, and the combining part is connected to the second end of the handle. The electric circular saw is good in balance performance.

Description

[0001] This application is a divisional application of the patent application with application number 201811521769.2 (the filing date of the original application is December 13, 2018, and the name of the invention is electric circular saw). technical field [0002] The invention relates to an electric tool, in particular to an electric circular saw.
