[0040] Working principle:

[0041] First, insert the fixing column 103 into the lithium battery injection port. Then, when the nail body 101 is parallel to the injection port, the column 207 will be pushed upward to disengage the second lock buckle 206 of the column 207 from the first lock buckle 205 of the connecting block 204. When both sides are disengaged, it can be proved that the nail body 101 is placed correctly. At this time, by rotating the rotating disk 202, the long connecting rod 201 is driven to move during the rotation of the rotating disk 202. The movement of the long connecting rod 201 drives the connecting block 204 to move at the same time, so that the support rod 208 The support rod 208 moves along the shape of the sliding groove 108, and at the same time, squeezes the storage air bag 203, so that the detection gas inside the storage air bag 203 enters the connecting pipe 211 through the outlet pipe 210, and then the detection gas pushes the ball 215 connected to the tension spring 214 to enter the compression chamber 212. When the compression chamber 212 is filled with detection gas, the sealing head 310 is forced to move downward, and then the horizontal plate 309 is driven to move downward together. In the process of the horizontal plate 309 moving downward, the movable When the wedge block 317 passes through one of the sets of snap rings 323, the wedge block 317 is reset under the push of the second spring 316, and the movable column 322 is restricted to prevent retreat. The downward movement of the cross plate 309 will force the short connecting rod 321 to move to both sides with the T-shaped key 315. When the T-shaped key 315 moves along the T-shaped slot 305, the push plate 304 fixed at one end of the push plate 304 will move to both sides. The push plate 304 is also provided with a rubber ring 311 to prevent it from falling off, and the connecting rod 314 will move downward together with the horizontal plate 309 when it moves downward, so that the piston 313 enters the second air outlet 303, and the air inside the annular groove 302 and the second air outlet 303 is compressed by continuously moving downward. When the internal pressure is sufficient, the air film 307 fixedly connected inside the annular groove 302 will expand outward to block the lithium battery filling port, prevent the internal electrolyte from flowing out, and facilitate subsequent welding.
