[0032] The working principle of the soft and hard adjustable flamethrower provided by the utility model is as follows:

[0033] Working principle of embodiment 1:

[0034] The soft and hard adjustable flamethrower described in the present invention adopts a unique design in the connection between the ceramic ring 2 and the flamethrower body 1. Specifically, the outer side of the ceramic ring 2 is fixedly connected with an external thread 6, and the end of the flamethrower body 1 is provided with an internal thread 7 matching it. Through the threaded connection between the external thread 6 and the internal thread 7, the ceramic ring 2 is firmly fixed on the flamethrower body 1.

[0035] When the ceramic ring 2 needs to be replaced, the operator only needs to rotate the ceramic ring 2 counterclockwise to gradually separate the external thread 6 from the internal thread 7 of the flamethrower body 1, thereby easily removing the ceramic ring 2 from the flamethrower body 1. Subsequently, the new ceramic ring 2 is aligned with the end of the flamethrower body 1 and rotated clockwise to tightly engage the external thread 6 with the internal thread 7, and the ceramic ring 2 can be replaced.

[0036] Working principle of embodiment 2:

[0037] Press the push rod 55 to compress the spring 56, so that the tooth ring 1 57 on the push rod 55 moves toward one end of the spring 5, and the tooth ring 1 57 disengages from the tooth ring 3 59 in the second connecting hole 54. At this time, the arc-shaped rotating part 52 is not restricted and can rotate arbitrarily. At this time, the arc-shaped rotating part 52 is rotated to expose the placement groove 510. At this time, the ceramic ring 2 can be easily removed for replacement.

[0038] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
