[0033] Kerosene lighter self-locking stage:

[0034] After the kerosene lighter is used, the cap 2 is manually closed, the cap 2 drives the support plate 305 to move, the support plate 305 drives the locking rod 304 and the second spring 306 to move, the end of the second spring 306 is attached to the frame 301 until the second spring 306 is compressed, so that the cap 2 can be opened when it is used next time, and the locking rod 304 is inserted into the interior of the frame 301, the locking rod 304 contacts the sliding rod 302, the locking rod 304 first drives the sliding rod 302 to slide to the left, the first spring 303 is compressed, and when the groove position of the locking rod 304 corresponds to the end of the sliding rod 302, the first spring 303 drives the sliding rod 302 to slide to the right under the elastic action, the sliding rod 302 fixes the position of the locking rod 304, and the locking rod 304 fixes the position of the support plate 305, thereby self-locking the cap 2 above the shell 1, so that the cap 2 of the kerosene lighter will not be accidentally opened relative to the shell 1, and it is convenient to self-lock when the kerosene lighter is not in use;

[0035] Kerosene lighter refilling stage:

[0036] When the kerosene lighter needs to be refilled with kerosene, a tool is inserted into the groove 403 and rotated. The groove 403 makes it easy to use the tool to rotate the disc 402. The disc 402 drives the stud 401 to rotate. The threaded column 401 is detached from the inside of the shell 1, and kerosene is added to the oil storage cotton 6 through the hole below the shell 1. After the kerosene is added, the threaded column 401 is put back, and the disc 402 is rotated in the opposite direction through the groove 403. The threaded column 401 is screwed into the inside of the shell 1. The disc 402 presses the rubber ring 404. The rubber ring 404 increases the sealing between the threaded column 401 and the shell 1 to prevent kerosene from leaking. The operation is relatively simple and it is not easy to cause kerosene to spill. When in use, it is convenient to add kerosene to the kerosene lighter.
