The present invention relates to the technical field related to electric hand tools, and in particular, to an electric tool battery plug-in structure.

Electric hand tools are commonly used in various production and maintenance environments. Among them, electric tools used with battery boxes are common standard tools in repair stations everywhere.

Although battery boxes bring convenient power to power tools, their assembly methods are limited to one direction and the center of gravity is fixed. However, the limitations of the maintenance work environment or the narrow space will make it difficult to extend the battery box, thereby causing restrictions and inconvenience to the user's operation.

In view of this, there is a need to improve the structure of existing electric hand tools so that users can freely adjust the insertion direction of the battery box assembly and the position of the center of gravity of the battery box according to their needs.

In view of the above-mentioned problems and deficiencies in the prior art, one of the main purposes of the present invention is to provide a power tool battery plug-in structure that overcomes the deficiencies in the prior art through structural innovation.

According to the above object of the present invention, the present invention discloses an electric tool battery plug-in structure, which includes an electric tool body and a battery box. The electric tool body has a power part and a handle at both ends respectively. The bottom end of the handle has a plug-in portion, which includes a plurality of side slide grooves, a bottom slide groove, and a plurality of working grooves recessed at a predetermined position of the plug-joint portion. The battery box corresponds to the socket plug part and has a slot matching the plug part, a plurality of hard rails matching the slide grooves on each side, and a terminal slot matching a plurality of electrical terminals in the working slot. By being composed of the above components, the battery box can be assembled in multiple directions according to needs, and can achieve requirements such as changing the center of gravity, effectively solving the shortcomings of the one-way assembly of traditional battery boxes.

Ribs 13, a plurality of working grooves 14, and reset positioning grooves 15.

The side slide grooves 11 are symmetrically recessed and formed on the end surfaces of both sides of the plug-in part 10, and both ends of the side slide grooves 11 in the extending direction are open.

The bottom slide groove 12 is recessed on the bottom end surface of the plug-in part 10 and matches the extending direction of each side slide groove 11 .

Each of the guide ribs 13 is symmetrically protruded at a predetermined position at the bottom of the bottom chute 12 .

Each of the working slots 14 is recessed and formed in the sectional surfaces at both ends of the plug-in part 10 , communicates with the bottom chute 12 and provides electrical terminals S for electrical coupling with the power part T1 .

Each of the positioning grooves 15 is recessed in the groove walls on both sides of each working groove 14 respectively.

The above-mentioned battery box 20 has a mounting groove 21, a plurality of hard rails 22, a plurality of guide grooves 23, and a plurality of terminal slots 24.

The embedding groove 21 is formed on the top surface of the battery box 20 to match the outer contour of the plug-in part 10, and has a slot that is upward and open at one end.

Each of the hard rails 22 is matched with the sliding grooves 11 on each side of the plug-in part 10 and is symmetrically protruding from the groove walls on both sides of the embedding groove 21 .

The guide grooves 23 are matched with the guide ribs 13 of the plug-in part 10 and are recessed at the bottom of the embedding groove 21 .

Each of the terminal slots 24 is matched with each electrical terminal S of the plug-in part 10 and is recessed in a predetermined position of the embedding groove 21 .
