In a specific implementation, an overall length of the functional component 2 is designed as the same as a length of the housing 1. Therefore, when the functional component 2 is in a normal state, the tool pull rod 21 is hidden in the accommodating cavity 11, and the top surface of the windshield sheet 22 is flush with the housing 1, and thus the windshield sheet 22 does not affect the normal use of the ignition device; when the tool pull rod 21 is slipped out from the bottom of the housing 1, the bottom of the tool pull rod 21 can be used as a cigarette presser or a screwdriver, which is convenient for a user to carry outdoors, reduces an occupation space and improves the practicability of the ignition device. Secondly, when the tool pull rod 21 is slipped from the top of the housing 1, the windshield sheet 22 can provide a protection function for a flame generated by the ignition device to prevent the flame from being blown out by wind.

In the above embodiment, most preferably, a circular mounting groove 221 is provided on the windshield sheet 22 starting from a side wall away from the housing 1, and a heat-insulating sheet 222 is embedded at the mounting groove 221 to prevent scalding the user. Therein, anti-slip strips 2221 are disposed horizontally on one side of the heat-insulating sheet 222 away from the windshield sheet 22 and are arranged evenly along the height, to facilitate the user to slip out the windshield sheet 22.

Please continue to refer to FIG. 1, FIG. 3 and FIG. 4. A limiting projection 31 is provided on a bottom outer side of the clamping sleeve 3, and the limiting projection 31 is arranged in a direction away from the slip through port 12; a limiting groove 111 in clamping connection with the limiting projection 31 is provided at the bottom of an inner side wall of the accommodating cavity 11; a length of the clamping sleeve 3 is less than a length of the housing 1; a limiting face 112 for abutting against the top end face of the clamping sleeve 3 is provided at a near top end of the accommodating cavity 11; and under the coordination of the limiting groove 111 and the limiting projection 31, the limiting face 112 is abutted against the top surface of the clamping sleeve 3 to subsequently fix two ends of the clamping sleeve 3.
