Abstract

The invention provides a power tool, which includes: a casing, an electric motor accommodated in the casing, a storage battery for supplying electric power to the electric motor, a handle arranged on the casing, and a handle arranged on the handle for controlling the electric motor A trigger switch for the power supply of the battery, a remaining energy display for displaying the remaining energy of the storage battery, and a lock-release switch, which is arranged on the handle and is configured to allow the trigger switch to be operated and to lock-release switch Started showing remaining energy on the remaining energy display while maneuvering.

Description

technical field [0001] The present invention relates to a power tool driven by a battery as a power source, and more particularly, the present invention relates to a power tool provided with a display portion for displaying remaining energy of the battery. Background technique [0002] A power tool driven by a battery and provided with a display section for displaying the remaining energy of the battery has been proposed. For example, Japanese Patent Application Publication No. 2009-72892 discloses a power tool provided with a display portion and a display switch located beside the display portion. The display is partly provided by light emitting elements such as LEDs. Once the display switch is pressed, the remaining capacity of the battery is displayed on the display section. [0003] However, according to such conventional power tools, the display switch is to be pressed by one hand of the user, and at the same time, the handle of the power tool is grasped by the other ...
