Abstract

The invention relates to a rechargeable lithium battery electric tool, comprising a clamping head part, a gearbox, a motor, a handle and a battery pack, wherein the battery pack is arranged inside the handle and comprises 4 lithium batteries, a battery shell and a battery base, the four lithium batteries are installed inside the battery shell the bottom of which is provided with the battery base, and the battery base is in inserted connection with the handle; the rechargeable lithium battery electric tool has the advantages that: the structure is simple and novel, the use is convenient; based on the basic design concept that the advantages of compact rechargeable lithium battery electric tools and large-power output rechargeable lithium battery electric tools are combined, the rechargeable lithium battery electric tool of the invention, on one hand, meets the power demand of large power output by adopting a 14.4V(14.4V to 16V) lithium battery system as power base and platform, and on the other hand, shortens own overall volume because the battery pack including the 4 lithium batteries is designed inside the handle. At the same time, the power of the tool is improved while the overall volume is reduced owing to the use of short rare earth motor.

Description

[technical field] [0001] The invention relates to the technical field of electric tools, in particular to a rechargeable lithium electric power tool using a 14.4V (14.4-16V) lithium electric system as the power basis, such as electric drills, electric wrenches, angle grinders, jig saws and the like. [Background technique] [0002] At present, there are mainly two types of rechargeable lithium-ion electric tools: one is compact, and the other is high-power output. On the market, the voltage output of 3.6V, 7.2V and 10.8V is the compact category, and the voltage output of 14.4V (14.4-16V), 18V, 21.6V and 36V is the high-power output category (see figure 1 ). [0003] The advantage of the compact type is that it is light and portable, but its disadvantage is that it has low power and cannot be used for high-power output products (such as impact drills, angle grinders, and jig saws, etc. cannot be applied to 3.6V, 7.2V, and 10.8V platforms). Therefore, among the compact lithiu...
