[0030] Furthermore, a photoelectric switch 11 for detecting the positions of the two clamping sliders 10 is provided on the substrate 1 .

[0031] Furthermore, it also includes a moving element 12, which is slidably set on the guide rail 9 and located between the first clamping jaw 3 and the second clamping jaw 4. The middle part of the first connecting member 5 is rotatably connected to the moving element 12.

[0032] Furthermore, the reset element 8 is a spring, and both the first clamping jaw 3 and the second clamping jaw 4 are provided with connecting ends, and both ends of the spring are respectively connected to the two connecting ends.

[0033] Furthermore, elastic members 13 are provided between the first connecting member 5 and the moving element 12 , the first clamping jaw 3 , and the second clamping jaw 4 .

[0034] Furthermore, the side walls of the first clamping jaw 3 and the side walls of the second clamping jaw 4 are both provided with sensing elements 15 .

[0035] The working principle of this utility model:

[0036] In this embodiment, the direction of the inner end of the first jaw 3 and the direction of the inner end of the second jaw 4 are toward the battery cell 14. The first jaw 3 and the second jaw 4 are connected by multiple connecting parts, namely the first connecting part 5, the second connecting part 6, and the third connecting part 7. The multiple connecting parts can be selected from connecting rods, hinges, hinges and other connecting structures; in this embodiment, the first connecting part 5, the second connecting part 6, and the third connecting part 7 form a hinge-like structure. When the telescopic element 2 drives the first jaw 3, the multiple connecting parts can limit the maximum relative distance between the first jaw 3 and the second jaw 4 and produce a linkage effect at the same time, so that the first jaw 3 and the second jaw 4 move after the maximum distance is separated. At the same time, the reset element 8 can provide elastic force to cause the first jaw 3 and the second jaw 4 to move closer to each other. When the battery cell 14 needs to be released, , driving the telescopic element 2 to drive the first clamping jaw 3 and the second clamping jaw 4 to separate, so that the first clamping jaw 3 and the second clamping jaw 4 move away from each other after overcoming the elastic force provided by the reset element 8; when it is necessary to clamp the battery cell 14, driving the telescopic element 2 to drive the first clamping jaw 3 and the second clamping jaw 4 to move closer to each other, at this time, the telescopic element 2 drives the first clamping jaw 3 to move in the same direction as the elastic force direction of the reset element 8. When the distance between the first clamping jaw 3 and the second clamping jaw 4 reaches a certain degree, the elastic force direction of the reset element 8 on the first clamping jaw 3 and the second clamping jaw 4 is the direction in which the first clamping jaw 3 and the second clamping jaw 4 move away from each other, so as to avoid collision between the first clamping jaw 3 and the second clamping jaw 4 or avoid excessive clamping force between the first clamping jaw 3 and the second clamping jaw 4 to damage the battery cell 14.

[0037] In addition, the upper end of the first jaw 3 and the upper end of the second jaw 4 are both provided with a detachable structure, and the detachable structure is provided with a slot. The upper end of the first jaw 3 extends horizontally into the slot. The bottom of the detachable structure (hinged, etc.) is movably provided with an L-shaped anti-slip block to press against the bottom of the upper end of the first jaw 3. The bottom surface of the upper end of the detachable structure is provided with a protrusion to press the groove of the upper end of the first jaw 3. The upper end of the first jaw 3 and the upper end of the second jaw 4 are both provided with a groove. The midpoint of the protrusion and the midpoint of the anti-slip block are not on the same vertical line, so that the two horizontal parts of the first jaw 3 are respectively subjected to vertical upward and vertical downward clamping forces. Furthermore, the protrusion cooperates with the groove to prevent the first jaw 3 from loosening in the vertical and horizontal directions. Similarly, the upper end of the second jaw 4 is also provided with a detachable structure to facilitate the replacement of the first jaw 3 and the second jaw 4. The detachable structures can be fixedly connected to the corresponding sliders so that the first jaw 3 and the second jaw 4 slide in cooperation with the guide rail 9;

[0038] In addition, the upper end of the first clamping jaw 3 and the upper end of the second clamping jaw 4 can also be connected to the corresponding clamping jaw slide 10 through other detachable connection structures, or the upper end of the first clamping jaw 3 and the upper end of the second clamping jaw 4 can be directly connected to the corresponding clamping jaw slide 10; wherein, the upper end of the first clamping jaw 3 can be connected to the telescopic end of the telescopic element 2 through a detachable mechanism, or the upper end of the first clamping jaw 3 can be directly connected to the telescopic end of the telescopic element 2. In this embodiment, the telescopic element 2 is a cylinder.

[0039] The photoelectric switch 11 detects the position of the corresponding clamping slider 10, thereby determining the position of the first clamping jaw 3 and the second clamping jaw 4. The sensing element 15 detects whether the battery cell 14 is clamped. The elastic member 13 maintains a certain connection between the first, second, and third connectors 5, 6, and 7, further providing elastic force to hold the battery cell 14. The elastic member 13 can also be a spring or other elastic element.
