The mutual abutment between the first matching portion 710 and the inner periphery of the connecting tube 110 is conducive to improving the positioning accuracy of the connecting tube 110 and achieving the limitation of the connecting tube 110 in the transverse plane.

[0070] Reference Figure 1 、 Figure 3 and Figure 4 As shown, specifically, the first matching part 710 is a positioning ring, the inner periphery of the positioning ring can abut against the outer periphery of the positioning column to achieve the limitation of the pressure cover 700 and the center tube 300 in the transverse plane, and the outer periphery of the positioning ring can abut against the inner periphery of the connecting tube 110 to achieve the limitation of the pressure cover 700 and the connecting tube 110 in the transverse plane.

[0071] Reference Figure 1 、 Figure 3 and Figure 4 As shown, it can be understood that, specifically, a handle 800 is connected to the upper end of the pressure cap 700, so that the user can manipulate the pressure cap 700 from a distance to connect or separate the pressure cap 700 and the connecting tube 110, which is beneficial to reduce the risk of the user touching the welding part of the connecting tube 110 when manipulating the pressure cap 700, or reduce the impact of the heat generated by the welding part of the connecting tube 110 on the user's manipulation of the pressure cap 700.

[0072] Reference Figure 1 、 Figure 3 and Figure 4 As shown, the handle 800 includes a first sub-rod extending laterally and a second sub-rod extending vertically. The upper end of the second sub-rod is fixedly connected to the middle part of the first sub-rod, and the lower end of the second sub-rod is fixedly connected to the upper end of the pressure cover 700. After the user holds the first sub-rod, the user can apply downward pressure to the pressure cover 700 to make the pressure cover 700 fit into the center tube 300, or apply upward pulling force to the pressure cover 700 to make the pressure cover 700 withdraw from the center tube 300, and then the user can take out the connecting tube 110 that is sleeved on the center tube 300.

[0073] Reference Figure 1 、 Figure 2 and Figure 3As shown, a welding device of an embodiment of the present invention includes a welding workbench as shown in any of the above embodiments. The center tube 300 and the support assembly 400 are both connected to the upper end of the workbench 200, and a plurality of support assemblies 400 are arranged around the center tube 300. The center tube 300 is constructed to place the connecting tube 110. When the star-shaped chair leg 100 is mounted, the user can put the connecting tube 110 on the upper end of the center tube 300, and use the mutual contact between the connecting tube 110 and the center tube 300 to achieve the positioning of the connecting tube 110. Then, the support leg 120 can be placed on the upper end of the first bracket 410 and the second bracket 420, and use the support of the first bracket 410 and the second bracket 420 to support the support leg 120, so as to preliminarily achieve the positioning of the support leg 120 and the connecting tube 110. The welding workbench also includes a pressure arm 500, and a plurality of pressure arms 500 are provided. Each support assembly 400 is connected to at least one pressure arm. Corresponding to 500, the pressure arm 500 is rotatably connected to the upper end of the workbench 200 so that the pressure arm 500 can rotate around the horizontal axis. By rotating the pressure arm 500, the user can make the pressure arm 500 apply downward pressure to the support leg 120 placed on the support assembly 400 to limit the support leg 120, so as to ensure that the support leg 120 remains in contact with the connecting tube 110, which is beneficial to improving the positioning accuracy of the support leg 120 and the connecting tube 110, and reducing or avoiding the problem of the support leg 120 offsetting relative to the connecting tube 110 during the welding process. The welding tooling table can achieve contact with support legs 120 of different shapes or sizes by adjusting the rotation angle of the pressure arm 500 relative to the workbench 200. The operation is simpler and the applicability is higher, which is beneficial to improving the welding efficiency of the star-shaped chair leg 100.

[0074] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
