Abstract

The invention provides an electric tool battery protective sleeve, which is characterized in that a flange is arranged on the upper side of the surface of an inner shell, a limiting groove is formed in the outer side of the flange, and a supporting shaft is installed in the inner shell; an outer shell is arranged on the outer side of the inner shell, a convex block is arranged on the upper side of the outer shell, one side of the convex block extends into the limiting groove, and the convex block is in clearance fit with the limiting groove; and according to the electric tool battery protective sleeve provided by the invention, a protection box is arranged outside the battery, so that the battery is prevented from being in direct contact with an external hard object to cause damage, the protection box is divided into the inner shell and the outer shell, a supporting reed is arranged in the buffer cavity formed between the inner shell and the outer shell, the impact force can be buffered and absorbed, and the outer shell is provided with displacement spaces in multiple directions relative to the inner shell, and is matched with the supporting reed to buffer the impact in multiple directions, so that the battery is better protected.

Description

technical field [0001] The invention relates to the field of battery protection, in particular to an electric tool battery protection case. Background technique [0002] A battery refers to a cup, tank or other container or part of a composite container that contains an electrolyte solution and a metal electrode to generate an electric current, and is a device that converts chemical energy into electrical energy. [0003] Batteries include power batteries, which are power sources that provide power for tools, and mostly refer to batteries that provide power for electric vehicles, electric trains, electric bicycles, and golf carts; [0004] For electric tools powered by batteries, the value and price of the battery often account for a large proportion of the entire machine combination, and the battery is expensive. Currently, the battery is located at the bottom of the electric tool, which is easy to directly contact with external hard objects and scratches easily. Or damage...
