[0038] Specifically, see Figure 7 The purpose of this embodiment is to press the first annular product 7 against the inner wall of the second annular product 8. The first annular product 7 is a thin sheet component with a certain degree of elasticity. Several slide rails 4 are arranged in a ring or near-ring shape, and several sliders 6 are also arranged in a ring or near-ring shape. The second end 65 of the slider 6 is located outside the slide rail 4. The second end 65 has a contoured structure, and several second ends 65 can form a ring similar to the first annular product 7. A hook 64 is provided at the bottom of the second end 65, and the end of each hook 64 has a protrusion 641 facing the first annular product 7. Several hooks 64 are arranged in a ring or near-ring shape. The slide rail 4 has a first step 41, and the slider 6 has a second step 66. The two ends of the first spring 62 respectively abut against the second step 66 and the inner side of the rotating disk 8, and the two ends of the second spring 63 respectively abut against the second step 66 and the inner side of the rotating disk 8. The inner side of the second step 66 and the rotating disk 2; the bottom of the annular cavity 3 is provided with several arc-shaped waist holes 31, and the bottom of the rotating disk 2 is provided with several limiting posts 21, which are matched with the arc-shaped waist holes 31; two waist holes 32 are symmetrically provided on the outer side of the annular cavity 3, and two levers 22 are symmetrically provided on the outer side of the rotating disk 2, which pass through the waist holes 32 and are exposed on the fixed disk 1; a hollow part 642 is provided between the two hooks 64 located on the same slider 6, and several welding points are provided between the first annular product 7 and the second annular product 8. The welding points are aligned through the hollow part 642 and the first annular product 7 is welded to the inner wall of the second annular product 8, such as by laser welding.

[0039] See Figures 1 to 8 The process of pressing the first annular product 7 against the inner wall of the second annular product 8 is as follows: First, the second annular product 8 is fixed to the carrier, and the first annular product 7 is pre-placed inside the second annular product 8; Second, by turning any of the levers 22, the rotating disk 2 is rotated to a first predetermined position, as detailed below. Figures 2 to 4The schematic diagram shows that several arc-shaped protrusions 61 simultaneously disengage from several arc-shaped grooves 5, the arc-shaped protrusions 61 are pushed and approach the center of the rotating disk 2, and several hooks 64 simultaneously approach the center of the rotating disk 2 and retract inward.

During the rotation of the rotating disk 2, through the cooperation of the arc-shaped protrusion 61 and the arc-shaped groove 5, a number of sliders 6 are driven to move synchronously along the slide rail 4. During the movement of the sliders 6, a number of hooks 64 are synchronously retracted or expanded. When expanding, the first annular product 7 is welded to the inner wall of the second annular product 8. It has the advantage of consistent and synchronous pressing force in all directions, so that the first annular product 7 can be welded to the second annular product 8 with high precision.
