[0034] The technical scheme of the utility model sets the clamping groove on the battery pole piece, sets the containing groove for inserting the plug-in part on the shell, recesses the clamping groove on the part corresponding to the clamping groove of the shell, when the plug-in part is inserted into the containing groove, the clamping groove coincides with the clamping groove, it can be understood that the number of the battery pole pieces is multiple, so the number of the clamping grooves is multiple, and the number of the clamping groove is one, that is, a whole recess groove through the shell, the clamping groove is communicated with the containing cavity, so that the clamping groove on the battery pole piece in the containing cavity is also communicated with the clamping groove, so that the clamping assembly can abut against the groove wall of the clamping groove and the clamping groove, so that the clamping assembly can simultaneously limit the shell and the battery pole piece. When installing, the pressing end of the clamping piece is pressed, so that the clamping end moves to the working position away from the clamping groove, at this time, the shell is pressed down to the battery pole piece and the plug-in part is inserted into the containing groove, which will not be blocked by the clamping end, after insertion, the pressing end is released to return to the initial position, the elastic restoring force of the reset piece pushes the clamping end into the clamping groove, so that the clamping end abuts against the clamping groove and the clamping groove to complete the fixation, thereby completing the installation, when disassembling, only the pressing end needs to be pressed, so that the clamping end is separated from the clamping groove, and then the shell can be dismounted from the battery pole piece.
