[0024] The inner wall of the protective cover 2 is provided with two reset grooves 201 , and reset springs 202 are arranged inside the two reset grooves 201 . One end of the reset spring 202 is connected to a limit block 203 . Both sides of the test head 103 are provided with a slot 204 that matches the limit block 203 .

[0025] The protective cover 2 can protect the test head 103, so as to prevent the test head 103 from being squeezed and damaged. When the lithium battery 104 needs to be tested, the protective cover 2 can be grasped and pulled downward. When the protective cover 2 moves, the limit block 203 starts to move downward. The limit block 203 moves toward the inside of the reset groove 201 due to the shape of the slot 204. When the limit block 203 enters the reset groove 201, it will continue to squeeze the reset spring 202. After being squeezed, the reset spring 202 will become compressed, causing the limit block 203 to leave the slot 204. When the limit block 203 enters the reset groove 201, the protective cover 2 The fixation is released, so that the protective cover 2 can be removed and the lithium battery 104 can be tested. When the test head 103 is to be protected, the protective cover 2 is pushed in the direction of the test head 103, so that the test head 103 enters the protective cover 2. When the test head 103 enters the protective cover 2, the limit block 203 enters the reset groove 201. When the test head 103 completely enters the protective cover 2, the slot 204 corresponds to the position of the reset groove 201, so that the reset spring 202 begins to return to its original state. When the reset spring 202 returns to its original state, it will push the limit block 203 back to its original position, so that the limit block 203 enters the slot 204, so as to fix the protective cover 2.

[0026] A cylindrical test head 303 is arranged between the clamping plate 3 and the lithium battery 104, a fixed block 304 is connected to one side of the slider 301, a threaded hole 305 is opened on the top of the fixed block 304, a threaded rod 306 is connected to the inside of the threaded hole 305 through threaded engagement, and a pressure plate 307 is connected to the top of the threaded rod 306.

[0027] When the lithium battery 104 is to be fixed, the clamping plate 3 is pushed in the direction of the lithium battery 104. The clamping plate 3 will start to move in the direction of the lithium battery 104 due to the sliding connection between the slider 301 and the slide groove 302. The clamping plate 3 will contact the lithium battery 104 when moving in the direction of the lithium battery 104, so as to fix the lithium battery 104. When the clamping plate 3 contacts the lithium battery 104, the pressing plate 307 is rotated. After the pressing plate 307 rotates, it will rotate with the threaded rod 306. When the threaded rod 306 rotates, it will gradually move downward due to the threaded engagement connection with the threaded hole 305. When the threaded rod 306 moves, it will move with the pressing plate 307. When the pressing plate 307 moves, it contacts the surface of the base 1 for compression and fixing. Therefore, the clamping plate 3 can be fixed, so as to limit the position of the lithium battery 104.

[0028] One side of the cylindrical test head 303 is connected to the limiting block 24, one side of the clamping plate 3 is provided with a limiting groove 401 that matches the limiting block 24, both side surfaces of the limiting block 24 are connected with movable blocks 402, the inside of the limiting groove 401 is provided with a movable groove 403 that matches the movable block 402, both side surfaces of the movable block 402 are provided with fixing holes 404, both side surfaces of the clamping plate 3 are provided with positioning holes 405, and pins are arranged inside the fixing holes 404, one side of the clamping plate 3 is connected with two sliders 301, one side of the connecting plate 101 is provided with a sliding groove 302 that matches the slider 301, one side of the movable plate 102 is connected with two moving blocks 105, and one side of the connecting plate 101 is provided with a moving groove 106 that matches the moving block 105.

[0029] Before the lithium battery 104 needs to be clamped, the pin is grasped, and then the pin is pulled outward to make the pin leave the fixing hole 404. When the pin leaves the fixing hole 404, the movable block 402 can be taken out of the movable groove 403, so that the clamping plate 3 can contact the lithium battery 104, so as to limit and fix the lithium battery 104. When facing a cylindrical lithium battery, the movable block 402 can be aligned with the movable groove 403, and the movable block 402 is placed after alignment so that the movable block 402 enters the movable groove 403. When the position of the fixing hole 404 on the movable block 402 corresponds to the positioning hole 405, the pin is inserted into the positioning hole 405, so that the pin passes through the positioning hole 405 and enters the fixing hole 404, so that the movable block 402 can be limited and fixed, so as to install the cylindrical test head 303, so that the cylindrical lithium battery 104 can be tested through the cylindrical test head 303.

[0030] The specific workflow is:

[0031] Before the lithium battery 104 needs to be clamped, the pin is grasped, and the pin is pulled outward after being grasped to make the pin leave the fixing hole 404. After the pin leaves the fixing hole 404, the movable block 402 can be taken out of the movable groove 403, so that the clamping plate 3 can contact the lithium battery 104, so as to limit and fix the lithium battery 104. When facing a cylindrical lithium battery, the movable block 402 can be aligned with the movable groove 403, and the movable block 402 is placed after alignment so that the movable block 402 enters the movable groove 403. When the position of the fixing hole 404 on the movable block 402 corresponds to the positioning hole 405, the pin is inserted into the positioning hole 405, so that the pin passes through the positioning hole 405 and enters the fixing hole 404, so that the movable block 402 can be limited and fixed, so as to install the cylindrical test head 303, so that the cylindrical lithium battery 104 can be tested through the cylindrical test head 303;

[0032] When the lithium battery 104 is to be fixed, the clamping plate 3 is pushed in the direction of the lithium battery 104. The clamping plate 3 will start to move in the direction of the lithium battery 104 due to the sliding connection between the slider 301 and the slide groove 302. The clamping plate 3 will contact the lithium battery 104 when moving in the direction of the lithium battery 104, so as to fix the lithium battery 104. When the clamping plate 3 contacts the lithium battery 104, the pressing plate 307 is rotated. After the pressing plate 307 rotates, it will rotate with the threaded rod 306. When the threaded rod 306 rotates, it will be engaged with the threaded hole 305 and gradually move downward. When the threaded rod 306 moves, it will move with the pressing plate 307. When the pressing plate 307 moves, it will contact the surface of the base 1 to compress and fix it, so that the clamping plate 3 can be fixed, so as to limit the position of the lithium battery 104.

[0033] The protective cover 2 can protect the test head 103, so as to prevent the test head 103 from being squeezed and damaged. When the lithium battery 104 needs to be tested, the protective cover 2 can be grasped and pulled downward. When the protective cover 2 moves, the limit block 203 starts to move downward. The limit block 203 moves toward the inside of the reset groove 201 due to the shape of the card slot 204. When the limit block 203 enters the inside of the reset groove 201, the reset spring 202 will continue to be squeezed. After being squeezed, the reset spring 202 will become compressed, so that the limit block 203 leaves the inside of the card slot 204. When the limit block 203 enters the inside of the reset groove 201, the fixation of the protective cover 2 is released, so that the protective cover 2 can be disassembled, and the lithium battery 104 can be tested.

[0034] When the test head 103 is to be protected, the protective cover 2 is pushed toward the test head 103 so that the test head 103 enters the protective cover 2. When the test head 103 enters the protective cover 2, the limit block 203 enters the reset groove 201. When the test head 103 completely enters the protective cover 2, the slot 204 corresponds to the position of the reset groove 201, so that the reset spring 202 begins to return to its original state. When the reset spring 202 returns to its original state, it will push the limit block 203 back to its original position, so that the limit block 203 enters the slot 204, so as to fix the protective cover 2.
