Problems solved by technology

[0002] At present, electric tools are usually powered by a single battery pack. However, due to the manufacturing technology of the battery pack, the capacity of a single battery pack cannot support the long-term work of wireless electric tools. Therefore, in actual operations, when the battery pack capacity When it drops to a certain level, it is necessary to stop the operation to charge the battery pack, or replace the spare battery pack, which usually reduces the operator's work efficiency and brings great inconvenience to the operator

Abstract

The invention discloses an electric tool, comprising: a tool host, the tool host includes: a tool housing, an electrical device, and a host interface capable of introducing external electric energy into the electrical device, the host interface includes a host terminal, the electrical device and the host terminal Constitute an electrical connection; the electric tool also includes: a power component capable of supplying power to the electrical device through the host terminal, the power component includes: at least one battery pack and at least one auxiliary adapter, the battery pack includes a battery interface, and the battery interface includes battery terminals The auxiliary adapter includes: at least one collector interface that can be connected to the battery interface, at least one power supply interface that can be connected to the host interface or the collector interface of another auxiliary converter, and a conversion module that can realize voltage adjustment. The electric tool of the present invention can use a plurality of battery packs to supply power at the same time, which increases the working time and stability of the electric tool.

Description

technical field [0001] The invention relates to a power tool, in particular to an electric tool capable of connecting multiple battery packs and a charger adapted thereto. Background technique [0002] At present, electric tools are usually powered by a single battery pack. However, due to the manufacturing technology of the battery pack, the capacity of a single battery pack cannot support the long-term work of wireless electric tools. Therefore, in actual operations, when the battery pack capacity When it drops to a certain level, it is necessary to stop the operation to charge the battery pack, or replace the spare battery pack, which usually reduces the work efficiency of the operator and brings great inconvenience to the operator. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the object of the present invention is to provide an electric tool capable of connecting multiple battery packs at the same time. [0004] In order to a...
