Problems solved by technology

At this time, it is also required to make the electric tool shell as small as possible. If the electric tool shell is fixed with screws like traditional electric tools, and the components inside the shell are fixed with reinforcing ribs, the size of the electric tool is difficult to change. smaller, and the screws on the surface of the power tool will also affect the appearance and feel of the power tool

Abstract

The invention discloses an electric tool shell and an electric tool. The electric tool shell comprises at least one first shell element and at least one second shell element. The first shell elementsand the second shell elements are connected together along at least one contact line and / or contact face. The first shell elements and the second shell elements are connected without screws. Modularized assembling structures are adopted inside the electric tool, including at least one drive system unit module, at least one controller unit and at least one battery unit module which are all fixedlyconnected with the electric tool shell, wherein a locking structure is arranged on the drive system unit module. The electric tool is compact in structure and smaller in size, no screws are adopted for connection of the shell, and the surface of the shell is provided with visual holes as few as possible.

Description

technical field [0001] The invention relates to the field of electric tools, in particular to an electric tool casing, an electric tool provided with the casing, and an assembly method of the electric tool. Background technique [0002] As one of the common application tools, power tools can be seen everywhere, such as electric drills, electric saws, cutting machines, angle grinders, etc., and are widely used, including machinery industry, architectural decoration, landscaping, wood processing, financial processing, etc. It plays an indispensable role in social and economic development. Benefiting from the breakthrough of lithium battery technology, electric tools are gradually converted to clean energy for power supply. The battery capacity and safety of electric tools are expected to be greatly improved, while the cost of batteries will continue to decrease. As the penetration rate in households increases, electric tools need to be used for multiple purposes. With breakth...
