[0009] In the figure, 1. tube plate; 2. brass sleeve; 3. mounting plate; 4. positioning external teeth; 5. positioning tooth grooves; 6. abutment platform; 7. shaft platform; 8. connecting main shaft; 9. connecting plate. DETAILED DESCRIPTION

[0010] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0011] like Figure 1 , Figure 2 As shown, the brass insert structure of the arc tube comprises a tube plate 1, and the brass insert structure comprises a brass sleeve 2. The tube plate 1 is provided with a mounting plate 3 for inserting and installing the brass sleeve 2. The brass sleeve 2 is provided with a positioning outer tooth 4. The mounting plate 3 is provided with a positioning tooth groove 5 for positioning and installing the positioning outer tooth 4. The interior of the mounting plate 3 is hollow. The lower end of the positioning outer tooth 4 extends into the interior of the mounting plate 3. The interior of the mounting plate 3 is provided with a support platform 6 for the bottom of the positioning outer tooth 4 to support. The middle of the support platform 6 is provided with a middle hole for the brass sleeve 2 to pass through. The end of the sleeve 2 passes through the middle hole and out of the mounting plate 3. The bottom of the mounting plate 3 has a pillow block 7 for the end of the brass sleeve 2 to pass through. An axial hole is opened on the pillow block, and the end of the brass sleeve 2 has a corresponding hole corresponding to the axial hole. The axial hole and the corresponding hole are connected by a laterally inserted connecting spindle 8. The radial positioning effect is achieved by the positioning cooperation of the positioning external teeth 4 and the positioning tooth grooves 5. In addition, the setting of the abutment 6 can longitudinally position the brass sleeve 2 to achieve a directional embedding effect of the brass sleeve 2. Finally, the brass sleeve 2 is fixed by the connecting spindle 8.

[0012] Preferably, the other end of the tube sheet 1 has a connecting plate 9 .

[0013] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0014] Although the terms such as tube sheet 1, brass sleeve 2, mounting plate 3, positioning outer teeth 4, positioning tooth grooves 5, abutment table 6, pillow block 7, connecting spindle 8, connecting plate 9 are used more frequently in this article, the possibility of using other terms is not excluded. The use of these terms is only for more convenient description and explanation of the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
