Description

Battery pack [ Field of technology ] The present utility model relates to a battery pack, and more particularly, to a battery pack for a cordless tool. [ Background Art ] In many existing cordless power tools and other cordless devices, a battery pack is typically selected as the power source for ease of movement and portability. Nowadays, the battery pack is widely applied to electric tools such as electric drills, electric hammers, electric picks, angle grinders, blowers, grass cutters, lawn mowers, electric shears and other electric equipment, lighting lamps, sound equipment, outdoor power supplies and other electric equipment, and is popular among masses. However, the battery pack is mechanically and electrically connected with the cordless device through the plugging part, and under some special working conditions, the small battery pack sliding rail can break, for example, the vibration of the cordless device can occur due to the vibration working condition of the cordless device or unexpected falling and other conditions, and the guide rail of the plugging part can break and other adverse conditions. In view of the foregoing, it is desirable to provide an improved battery pack that overcomes the shortcomings of the prior art. [ Invention ] Aiming at the defects of the prior art, the utility model aims to provide a battery pack with high structural strength and convenient insertion and extraction.
