Description

Technical Field

[0001] The utility model belongs to the technical field of lithium-ion electric tools, and in particular relates to a lithium-ion electric tool with a firmly fixed battery. Background Art

[0002] At present, commonly used lithium-ion power tools and garden tools, such as electric saws, electric scissors, electric wrenches, electric drills, lawn mowers, hedge trimmers, etc., are usually equipped with lithium batteries for power supply for convenience of use. When installing lithium batteries in such lithium-ion power tools and garden tools in the prior art, the lithium batteries are directly clamped on the outside of the power tool housing. Since the connector on the power tool housing that is coupled with the lithium battery is a coupling iron sheet, the method of fixing the lithium battery in the prior art, in actual use, will easily cause the lithium battery to shake relative to the power tool housing because the power tool will generate a certain amount of vibration. When the lithium battery shakes, the coupling iron sheet on the power tool housing and the coupling connector of the lithium battery are likely to have poor contact, and even cause electric sparks, reducing the service life of the lithium battery.
