Abstract

A push power tool includes a motor, a body, a traveling device, a handle, and an operating device. The handle is connected to the body and configured for a user to hold. The operating device is configured for the user to operate. The operating device includes a first operating member and a second operating member. The first operating member is movable relative to the handle to control the traveling mode of the push power tool. The second operating member is movable relative to the handle to control the output power of the push power tool. In the push power tool, the first operating member includes a first operating portion disposed on a side of the handle facing away from the user, and the second operating member includes a second operating portion disposed on a side of the handle facing the user.

Claims (38)
