Abstract: The present invention provides an electric tool comprising a body, an operating component, an output shaft, and a stop mechanism. An arresting disc is disposed on the output shaft, and a groove is formed on the arresting disc; the stop mechanism comprises a protrusion, for example, a pin, which is operable so that the protrusion extends to insert into the groove to lock the output shaft. A stop mechanism of the present invention is easy to operate, delivers good safety performance, and has a relatively simple structure, which allows convenient production and subsequent maintenance. Further, a stop mechanism of the present invention automatically springs back to a non-stop position at which it detaches from the output shaft or the transmission gear of the transmission mechanism when the external force is lost, which prevents possible damage to the output shaft or transmission mechanism when a user starts the electric tool before releasing the stop mechanism.

Abstract: The present invention provides a lawn mower for cutting grass and maintaining the lawn surface. The lawn mower has a mower deck, a cutting blade driven by a motor, and a blade changing mechanism. The blade changing mechanism includes a fastener for securing the cutting blade to the motor, a blade securement tool for limiting the cutting blade from rotating, and at least one opening on the mower deck for removably receiving the blade securement tool. An edge guide is also provided on the mower deck. The lawn mower also includes a dynamic power management system configured to adjust a rotation speed of the motor dynamically based on a duty condition of the cutting blade.
