[0027] During operation, the baffle 2 is installed on the housing 1 by the mutual engagement between the card block 21 and the card slot in the housing 1, and the distance between adjacent baffles 2 can be changed by the mutual engagement between the card block 21 and the card slots at different positions in the housing 1, so as to adapt to the change of the relative diameter of the single cell within a certain range, thereby increasing the rationality of the device structure. The baffle 2 is installed on the extrusion assembly 3 through the installation opening 22, and the extrusion bottom plate 31 on the single baffle 2 has an elastic force to move away from each other under the elastic force of the elastic telescopic rod 32, thereby providing an elastic force for the extrusion rubber 33 to squeeze the outer wall of the single cell;

[0028] like Figure 2 and Figure 3 As shown, a clearance opening 23 is provided near the center of the top surface of the baffle 2, and the clearance opening 23 penetrates into the interior of the installation opening 22. An expansion opening 24 is provided above the clearance opening 23, and a limit assembly 4 is provided between the two extruded bottom plates 31;

[0029] When working, the baffle 2 is installed on the limiting component 4 through the mutual cooperation between the clearance opening 23 and the expansion opening 24. The limiting component 4 is a structure in the device that limits the position of the extrusion component 3 inside the single baffle 2;

[0030] like Figure 3 and Figure 4 As shown, the limiting assembly 4 includes a semicircular cover 41 and a rotating shaft 42. The semicircular cover 41 is fixed to the center of the side wall of one of the extruded bottom plates 31, and the rotating shaft 42 is vertically fixed to the side wall of the other extruded plate near the center.

[0031] During operation, the semicircular cover 41 and the rotating shaft 42 are respectively mounted on adjacent side walls of the two extrusion bottom plates 31 and move closer to or farther from each other following the movement of the extrusion bottom plates 31;

[0033] During operation, before installing the single battery, the extrusion bottom plate 31 on the extrusion baffle 2 is squeezed to make the semicircular cover 41 and the rotating shaft 42 close to each other. At this time, the limit lever 43 is pulled up by the lifting connecting rod 45 and the lifting handle 46 until the upper limit circular plate 44 and the semicircular cover 41 are engaged with each other, and the two extrusion bottom plates 31 are relatively fixed.

At this time, the limit lever 43 is pulled up by the lifting connecting rod 45 and the lifting handle 46 until its upper limit circular plate 44 and the semicircular cover 41 are engaged with each other, and the two extrusion bottom plates 31 are relatively fixed. After the battery is installed, press the lifting handle 46 downward. At this time, under the pressure of the lifting connecting rod 45, the limit lever 43 and the limit circular plate 44 are deflected downward as a whole, and the limit circular plate 44 is separated from the semicircular cover 41. At this time, the two extrusion bottom plates 31 are separated from each other under the elastic force of the elastic telescopic rod 32, so that the extrusion rubber 33 is pressed against the single battery. The extrusion of the outer wall is limited, wherein the baffle 2 is installed on the shell 1 to the baffle 2 by the mutual engagement between the clamping block 21 and the inner slot of the shell 1, the baffle 2 is installed on the extrusion assembly 3 through the installation opening 22, and the position of the extrusion bottom plate 31 is limited by the baffle cover 25 to prevent the extrusion bottom plate 31 from being separated from the baffle 2, and the extrusion bottom plate 31 on a single baffle 2 has an elastic force moving away from each other under the elastic force of the elastic telescopic rod 32, thereby providing an elastic force for the extrusion rubber 33 to extrude the outer wall of the single cell, and the baffle 2 is installed on the limit assembly 4 by the mutual cooperation between the clearance opening 23 and the expansion opening 24, thereby increasing the rationality of the device structure.
