It can be understood that, in other embodiments, other threaded workpieces can be disassembled and assembled by using the combustion chamber disassembling and assembling tool, and the disassembling and assembling of the swirler 30 is not limited to the embodiment.
Example two
Compared with the first embodiment, the present embodiment is different only in that: the adjusting groove is a through groove 22 penetrating through the positioning plate 2, and the limiting column 3 can be relatively movably inserted in the through groove 22. When the relative mounting groove 11 of locating plate 2 removed the regulation, spacing post 3 can remove logical 22 interior adaptability, and lead to the cooperation of groove 22 and spacing post 3 and can also realize spacing to locating plate 2, avoid locating plate 2 to deviate from mounting groove 11, the regulation of locating plate 2 was followed logical 22 of seting up the region and is carried on about, control the regulation about this moment. In this embodiment, the through groove 22 is a strip-shaped through hole opened in the height direction of the positioning plate 2, and when the positioning plate 2 is moved and mediated along the height direction of the mounting groove 11, the limiting column 3 can move in the strip-shaped through hole relatively, so that the height of the positioning plate 2 can be adjusted.
It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. This need not be, nor should it be exhaustive of all embodiments. And obvious variations or modifications therefrom are within the scope of the invention.
