[0023] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0024] Embodiment:

[0025] Please refer to Figures 1-2 The utility model provides a kind of ignition needle for facilitating installation of perforation, including needle body 1, needle body 1 is fixedly sleeved and installed sleeve 2, sleeve 2 includes inner ring 201, outer cover 202, limiting ring 203 and slit 204, the bottom of inner ring 201 is equipped with ring body, ring body outside is integrally connected outer cover 202, the top of outer cover 202 is equipped with limiting ring 203, outer cover 202 and limiting ring 203 are equipped with slit 204 around axis.

[0026] Specifically, the height of inner ring 201 is between one third and two thirds of the height of outer cover 202, and does not block the deformation of outer cover 202.

[0027] Specifically, as Figure 1 Indicated, outer cover 202 is outer convex arc shape, outer cover 202 is fixed, and forms two side limitings with limiting ring 203 on the inner and outer sides of stove head mounting hole, so that needle body 1 does not fall off.

[0028] Specifically, outer cover 202 is elastic metal material, and is heat-resistant and deformable.

[0029] Specifically, the ring diameter of ring body is less than 3mm, which provides space for the deformation of outer cover 202.

[0030] Specifically, the cut seam 204 is less than 2mm in width, the cover 202 is retracted, and the two sides of the cut seam 204 are not pressed against each other.

[0031] Working principle:

[0032] In use, the sleeve 2 is sleeved and fixed on the needle body 1, the body diameter of the needle body 1 is less than the diameter of the installation hole of the burner, then the needle body 1 is inserted into the installation hole of the burner, the cover 202 is elastically deformed and retracted, the limiting ring 203 is clamped at the position of the installation hole, the cover 202 is elastically counter-pressed, and the fixing of the needle body 1 is realized.

[0033] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
