[0015] Figure 3 The utility model DETAILED DESCRIPTION

[0016] A battery test clamp comprises a sampling body 1, an upper clamping plate 2 and a lower clamping plate 3, wherein the sampling body 1 is arranged on the upper clamping plate 2 and the lower clamping plate 3, the upper clamping plate 2 and the lower clamping plate 3 are rotatably connected via a rotating shaft 4, protrusions 5 are arranged on the upper clamping plate 2 and the lower clamping plate 3, notches 6 are arranged on the protrusions 5, a roller 7 is rotatably connected to the notch 6, spring holes 9 are arranged on the inner walls of the upper clamping plate 2 and the lower clamping plate 3, and springs 10 are fixed on the spring holes 9.

[0017] The upper clamping plate 2 is provided with a groove 12, the lower clamping plate 3 is provided with a sleeve 11, the sleeve 11 and the groove 12 are rotatably connected, and the rotating shaft 4 is inserted into the sleeve 11; the side ends of the roller 7 and the rotating shaft 4 are both provided with limiting rings 8; the number of the springs 10 is several; in a stress-free state, the upper and lower rollers 7 abut against each other.

[0018] Specifically, the upper clamping plate 2 and the lower clamping plate 3 are rotatably connected so that the sampling body 1 can clamp and release the battery.

[0019] Specifically, through the design of the spring 10, the upper clamping plate 2 and the lower clamping plate 3 are supported by the spring, so that the upper clamping plate 2 and the lower clamping plate 3 do not have a clamping force on the battery in the original state.

[0020] Specifically, through the design of the roller 7, the roller 7 can be inserted into a wedge block (not shown in the figure), so that the upper and lower clamping plates rotate around the rotating shaft 4, so that the sampling body has a clamping force, thereby clamping the battery.

[0021] Specifically, conventionally, the battery is directly plugged in and out of the sampling body, which causes great wear and tear on the battery. The utility model inserts a wedge-shaped block between the upper and lower rollers, which rotates when rolling, so that the wedge-shaped block is not easily worn and can always be inserted smoothly. After insertion, the sampling body ends of the upper and lower clamps can clamp the battery, and the wedge-shaped block is pulled out. Under the action of the spring, the upper and lower clamps are reset and the battery is released.

[0022] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
