The shaping process was carried out by pressing the parts a2 and a4 after snap-fit assembly on the part a 00a so that the amount of pressing at the part a4 was larger than that at the part a2, and at the same time, the part A, B, C was bent and molded.

The A, B, C parts are assembled by the following method: the B, C parts are inserted into the threaded cavities of the a-parts 00a, respectively, with B, C parts and a arranged correspondingly, respectively, and then the B, C parts are adjusted, respectively, to move radially along the a-parts 00a to provide a snap fit between the a-parts 00a, respectively B, C parts.

Clamping the B part 00B by B1 and B2 clamping devices to insert into the A part 00a, then moving the B1 and B2 clamping devices to enable A, B parts to carry out primary snap-fit assembly, then extracting the B1 clamping devices 210 positioned in the B part 00B from the B part 00B, and continuously moving the B1 and B2 clamping devices to enable A, B parts to be completely snap-fit assembled;

the C-part 00C is inserted into the a-part 00a by clamping the C-part 00C with the C1, C2 clamps, then moving the C1, C2 clamps so that the A, C parts make a preliminary snap fit, then withdrawing the C1 clamps 230 located inside the C-part 00C from the C-part 00C, and continuing to move the C1, C2 clamps so that the A, C parts are fully snap fit.

The ABC part 00c was molded by inserting the a1 molded sub-portion 410 into the lumen of the a part 00 a.

A21 and A22 molds 421 and 422 are also provided on the outer sides of the parts A2 and A4 of the part A00 a to press the part A00 a for molding.

After the shaping treatment, the B, C screw rod section is bent at the outer side body section of the A part 00a with the smaller diameter end to avoid the stretching of the A2 and A4 parts.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of the present invention, and these improvements and modifications should also be construed as the protection scope of the present invention. Structures, devices, and methods of operation not specifically described or illustrated herein are generally practiced in the art without specific recitation or limitation.
