[0024] After the test of the previous model of lithium battery is completed, the coarse turning hollow knob 2 is turned to drive the fixedly connected hollow large gear 5. Through the meshing of the comb tooth bar 8 and the hollow large gear 5, the two test pieces 25 move outward, and the sliding column 12 fixedly connected to the test piece 25 slides along the sliding track 13. Since the sliding track 13 is arc-shaped, when the sliding column 12 slides along the sliding track 13, it will drive the hollow rotating plate 10 to rotate around the first rotating shaft 23, and the rotating hollow rotating plate 10 will drive the rotating connecting rod 25 to rotate around the first rotating shaft 23. The rod 17 rotates around the first rod hole 16, and the linked baffle 20 rotates around the second rotating shaft 22 through the rotation connection between the vertical rod 19 and the second rod groove 18. Since the top of the test groove 27 and the linked baffle 20 are provided with a chamfered structure, when the linked baffle 20 rotates to be nearly horizontal, the lithium battery to be tested placed in the test groove 27 will roll downward along the slope to the buffer plate 11, and slowly stop at the bottom of the buffer plate 11 through the buffering effect of the buffer plate 11, completing automatic loading.
[0025] The working principle and use process of the utility model are as follows: after placing the lithium battery to be tested on the buffer plate 11, the coarse-turn hollow knob 2 is turned to drive the fixedly connected hollow large gear 5, and through the meshing of the comb tooth bar 8 with the hollow large gear 5, the two test pieces 25 move inward, and the test piece 25 close to the lithium battery pushes the lithium battery away from the buffer plate 11 to the hollow rotating plate 10, and then performs preliminary clamping, and then the fine-turn knob 3 is turned to drive the fixedly connected small gear 7, and through the meshing of the small gear 7 with the dense rack 9, the two test pieces 25 slowly move inward for further clamping, and then the lithium battery can be subjected to more accurate electrical testing, and the coarse-turn hollow knob 2 is turned to drive the fixedly connected hollow large gear 5, and through the meshing of the comb tooth bar 8 with the hollow large gear 5, the two test pieces 25 move outward, and the sliding column 12 fixedly connected to the test piece 25 slides along the sliding track 13. Since the sliding track 13 is arc-shaped, the sliding column 12 When sliding along the sliding track 13, the hollow rotating plate 10 will be driven to rotate around the first rotating shaft 23, so that the tested lithium battery will slide into the buffer pad in the unloading trough 28, protecting the lithium battery from damage by impact. The lithium battery slides along the inclined unloading trough 28 to the bottom of the unloading trough 28 to complete automatic unloading. When the hollow rotating plate 10 rotates around the first rotating shaft 23, the rotating hollow rotating plate 10 will push the rotating connecting rod 17 to rotate around the first rod hole 16, and the linked baffle plate 20 is connected to the second rod groove 18 through the rotation of the vertical rod 19 to rotate around the second rotating shaft 22. Since the top of the slot to be tested 27 and the linked baffle plate 20 are provided with a chamfered structure, when the linked baffle plate 20 is rotated to nearly horizontal, the lithium battery to be tested placed in the slot to be tested 27 will roll downward along the inclined surface to the buffer plate 11, and slowly stop at the bottom of the buffer plate 11 through the buffering effect of the buffer plate 11, thereby completing automatic loading.
