Angle-adjustable fixing mechanism

The utility model discloses an angle-adjustable fixing mechanism, which belongs to the technical field of laser welding machines and comprises a support frame, a mounting frame is arranged above the support frame, a cross-shaped sliding table is embedded below the mounting frame, and a fixing mechanism convenient for adjusting welding angles and fixing a welding machine is arranged below the cross-shaped sliding table. According to the laser welding head fixing device, the tail of a laser welding head is clamped into the fixing shell through the fixing mechanism, the two fixing rods are pushed by another worker, so that the fixing clamps are tightly clamped on the two sides of the laser welding head, at the moment, the buckles just penetrate out of the through holes in the other ends of the fixing rods, the elastic pieces eject out to limit the buckles, and then the fixing rods are fixed; and the laser welding head can be conveniently mounted and dismounted, so that the laser welding head is more convenient a
