[0037] Furthermore, a first detection hole 9 is formed at the bottom of the positioning groove 21 .

[0038] Furthermore, the fixture body 1 is also provided with a second detection hole 10 for detecting the battery cell 12 , and the second detection hole 10 is located at the left and right sides of the adapter plate positioning structure 2 .

[0040] Furthermore, a limiting protrusion is provided at the bottom of the short side limiting member 42 , and the limiting protrusion is used to prevent the short side limiting member 42 from sliding out of the transverse sliding groove 6 .

[0041] The working principle of this utility model:

[0042] In this embodiment, the fixation and positioning of the battery cell 12 can be ensured. The lever 7 on one of the limiting movable parts 4 is moved to cause it to move and prompt the other two limiting movable parts 4 to move synchronously to loosen or clamp the battery cell 12. That is, the clamp is controlled to clamp or loosen the battery cell 12 by moving the lever 7, thereby improving safety and convenience.

[0043] An adapter plate positioning assembly is provided between the two battery cell 12 positioning assemblies. One end of the battery cell 12 in each battery cell 12 positioning assembly can extend into the positioning groove 21 and overlap with one end of the adapter plate, so that part of the battery cell 12 and part of the adapter plate can be identified or processed together. The pad 11 is located above the connector 8, and the limiting fixture 3 is located on the side of the pad 11 close to the positioning groove 21. Figure 1 As shown, the long side limiter 41 is located on the upper and lower sides of the pad 11, the short side limiter 42 is located on the side of the pad 11 away from the positioning groove 21, and the battery cell 12 is placed above the pad 11. The adapter plate positioning structure 2 is provided with two positioning grooves 21 symmetrically arranged up and down about the center horizontal line. The positioning groove 21 is adapted to the shape and size of the adapter plate. The top limiter 22 is used to limit the top of the adapter plate in the positioning groove 21 to prevent the top of the adapter plate from sliding out of the positioning groove 21. The positioning guide 23 is located on the bottom concave side of the positioning groove 21, which is conducive to the adapter plate sliding into the positioning groove 21 and has a limiting effect on the bottom bend of the adapter plate in the positioning groove 21. As shown in the attached Figure 2 As shown, the first detection hole 9 provided at the bottom of the positioning groove 21 can be used to detect whether there is a transfer plate in the positioning groove 21. The second detection hole 10 below the pad 11 can be used to detect the position of the battery cell 12.

[0044] The battery cell 12 is placed above the backing plate 11. One connection end of the battery cell 12 extends into the positioning groove 21. The long-side limiting member 41 is used to limit the position of the long side of the battery cell 12. The short-side limiting member 42 is used to limit the position of one short side of the battery cell 12. The limiting and fixing member 3 is used to limit the position of the other short side of the battery cell 12. The shifting member 7 can move back and forth in the through groove 51. When the shifting member 7 is shifted, it drives the long-side limiting member 41 connected to the shifting member 7. At the same time, since the two long-side limiting members 41 are respectively connected to a short-side limiting member 42 through corresponding connections, a linkage relationship is generated among the three. When one of the long-side limiting members 41 is shifted, the two long-side limiting members 41 move away from the battery cell 12 synchronously up and down, and the left and right sides of the short-side limiting member 42 move away from the battery cell 12, or the two long-side limiting members 41 move closer to clamp the battery cell 12 synchronously up and down, and the left and right sides of the short-side limiting member 42 move closer to clamp the battery cell 12, completing the clamping or loosening of the battery cell 12. A reset element 13 can be arranged in the longitudinal chute 5. In this embodiment, the reset element 13 is selected as a spring. One end of the spring is connected to the bottom of the short-side limiting member 42, prompting the short-side limiting member 42 to maintain a tendency to approach the battery cell 12, so that the two long-side limiting members 41 also clamp the battery cell 12 simultaneously. In this embodiment, two copper adapter plates and two aluminum adapter plates can be placed in the two positioning grooves 21 respectively. The fixed limiting member is of a columnar structure to avoid blocking the connection end of the battery cell 12 from extending into the positioning groove 21. A limiting protrusion is arranged at the bottom of the short-side limiting member 42 and is clamped and limited with the bottom of the fixture body 1 to avoid the short-side limiting member 42 completely sliding out of the longitudinal chute 5. To improve the sliding efficiency, slide rails are arranged in both the transverse chute 6 and the longitudinal chute 5. Sliders are arranged at the bottoms of the long-side limiting member 41 and the short-side limiting member 42, and the sliders are in sliding fit with the corresponding slide rails to improve the sliding accuracy. In this embodiment, the connecting member 8 of the clock is a connecting piece. When the fixture clamps the battery cell 12, the connecting piece is in an inclined state relative to the long-side limiting member 41. When the fixture loosens the battery cell 12, the connecting piece is in a vertical state relative to the long-side limiting member 41 or the included angle formed between the two is greater than the included angle formed in the clamping state.

[0045] The technical means disclosed in the solution of the present utility model are not limited to the technical means disclosed in the above embodiments, but also include technical solutions formed by any combination of the above technical features. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present utility model.
