[0022] In this embodiment, the bracket base 1, the clamping assembly 2, the welding assembly 3 and the smoke processor 8 constitute the main structure of the bracket for horizontal welding of folding leaves involved in this application. The bracket not only realizes the rapid positioning and clamping of the welding of the folding leaves, but also facilitates the processing of the generated smoke.

[0023] It should be noted that the rolled edge of the folded leaf is located at the upper side after clamping, and the rolled edge of the rolled edge faces the laser welding head 34 at the rear side.
