The wrist tube portion 2 is cylindrical in shape as a whole. Both ends of the wrist tube portion 2 are open. The upper end of the wrist tube portion 2 is a welding connection. The lower end of the palm portion 1 is used for welding and connection with the lower end of the wrist tube portion 2.

[0024] The palm portion 1 is provided with a first straight-tube welding section 4 at its welding connection, the first straight-tube welding section 4 extends from the lower end of the palm portion 1, the length of the first straight-tube welding section 4 is 2mm-5mm, preferably 4mm, and the cross section of the first straight-tube welding section 4 is circular. The wrist barrel portion 2 is provided with a second straight-tube welding section 5 at its welding connection, the second straight-tube welding section 5 extends from the upper end of the wrist barrel portion 2, the length of the second straight-tube welding section 5 is 2mm-5mm, preferably 4mm, and the cross section of the second straight-tube welding section 5 is circular.

[0025] The first straight welding section 4 is welded to the second straight welding section 5, thereby realizing a fixed connection between the lower end of the palm portion 1 and the upper end of the wrist barrel portion 2. The base portion 3 is fixedly disposed at the lower end of the wrist barrel portion 2. In one embodiment, the base portion 3 is fixed to the lower end of the wrist barrel portion 2 by welding, and the base portion 3 is used for installation with a production line, thereby realizing the installation and fixation of the integral metal hand mold on the production line.

[0026] Therefore, the present application can solve the problem of the welding step difference between the palm 1 and the wrist tube 2 by welding the first straight tube welding section 4 and the second straight tube welding section 5, while ensuring the roundness of the palm 1 and the wrist tube 2 when they are welded, and will not cause welding problems between the palm 1 and the wrist tube 2 due to problems such as the oval shape of the palm 1, thereby effectively improving the production quality.

[0027] In order to solve the problem of welding alignment between the palm part 1 and the wrist tube part 2, refer to Figure 3 As shown, in the present application, the palm portion 1 has a first axis alignment member 6 embedded in the first straight tube welding section 4, and the wrist tube portion 2 has a second axis alignment member 7 embedded in the second straight tube welding section 5, and the first axis alignment member 6 and the second axis alignment member 7 are installed in coordination.

[0028] In one embodiment, referring to Figure 3 and Figure 4As shown, the first axial alignment member 6 includes a first mounting ring 61, a mounting column 62 and a plurality of first connecting pieces 63. The first mounting ring 61 is an annular structure. The mounting column 62 is arranged at the center of the first mounting ring 61.

One end of the first connecting piece 63 is connected to the inner wall of the first mounting ring 61, and the other end of the first connecting piece 63 is connected to the outer wall of the mounting column 62. The mounting column 62 is a solid columnar structure, and the length direction of the mounting column 62 is arranged along the axial direction of the first mounting ring 61.

[0029] It is worth noting that a plurality of first protrusions 8 are circumferentially arranged on the inner wall of the first straight tube welding section 4, and a first groove 9 is circumferentially arranged on the outer wall of the first mounting ring 61 to cooperate with the first protrusions 8. The cooperation between the first protrusions 8 and the first grooves 9 improves the installation stability of the first mounting ring 61 in the first straight tube welding section 4.

[0030] In one embodiment, referring to Figure 3 and Figure 5 As shown, the second axial alignment member 7 includes a second mounting ring 71, a mounting sleeve 72 and a plurality of second connecting pieces 73. The second mounting ring 71 is an annular structure. The mounting sleeve 72 is arranged at the center position of the second mounting ring 71. The plurality of second connecting pieces 73 are arranged between the second mounting ring 71 and the mounting sleeve 72 at intervals along the circumferential direction. One end of the second connecting piece 73 is connected to the inner wall of the second mounting ring 71, and the other end of the second connecting piece 73 is connected to the outer wall of the mounting sleeve 72. The mounting sleeve 72 is axially hollow. When the palm portion 1 and the wrist tube portion 2 are aligned, the mounting sleeve 72 is used to be plugged into and matched with the mounting column 62, thereby realizing axial alignment of the palm portion 1 and the wrist tube portion 2.

[0031] It is worth noting that a plurality of second protrusions 10 are circumferentially arranged on the inner wall of the second straight-tube welding section 5, and a second groove 11 is circumferentially arranged on the outer wall of the second mounting ring 71 to cooperate with the second protrusions 10.
