Description

Technical Field

[0001] The utility model relates to the field of lithium-ion drilling machines, in particular to a shell structure of a lithium-ion drilling machine. Background Art

[0002] At present, the Chinese utility model with the announcement number CN213859099U discloses a shock-absorbing and anti-fall lithium electric drill housing, including a main body, an elastic spring and a Velcro. The interior of the main body is connected with an annular airbag, and the inner side of the annular airbag is connected with a protective cabin. The outer surface of the main body is provided with a fixing ring, and the left end face of the fixing ring is connected with a sleeve. The elastic spring runs through the interior of the sleeve, and the left end face of the elastic spring is connected with an anti-slip ring. The right end face of the main body is connected with an auxiliary handle, and the lower end face of the main body is connected with a grip. The Velcro is fixed to the side surface of the grip, and the outer surface of the Velcro is provided with an auxiliary handle. This product has an annular airbag, which can protect the surroundings of the protective cabin. The characteristics of the annular airbag can protect the motor in the protective cabin after the product accidentally falls to the ground, preventing the motor from being injured. This product is provided with an anti-slip ring, so that the direction of the product can remain unchanged during operation, preventing the device from screwing the screw crooked during operation.

[0003] The existing lithium-ion drill shell structure cannot be adapted to different types of lithium batteries. The traditional lithium-ion drill shell structure can only install one type of controller component, and a single type of controller can only be paired with a lithium battery pack of the corresponding type of controller. Different lithium batteries on the market are equipped with different types of controller components. Therefore, if customers buy lithium-ion drills of different brands, the lithium batteries cannot be used interchangeably, which reduces practicality and applicability. In addition, during the tightening process of the screws, the screws and screwdrivers of the lithium-ion drills on the market do not have a fixed placement, which is not conducive to the operator's taking, resulting in reduced efficiency and insecurity, and inconvenient to use. It is also not convenient to install and disassemble the base. The lithium battery is installed at the bottom of the base. During use, the lithium battery needs to be replaced frequently, which makes the parts in the base easy to be damaged and needs to be repaired. During maintenance, the base needs to be disassembled for maintenance, and the base is generally fixed and installed with bolts and the housing. When disassembling the base, tools need to be used to disassemble and assemble it. The disassembly and assembly process is relatively cumbersome, which increases the workload and reduces the work efficiency. In order to solve the above problems, we propose a lithium-ion drill shell structure. Utility Model Content
