A cross-hole structure 11 is recessed at the lower end of the connecting rod 1. A cross-shaped boss 21 is provided on the upper end face of the main body block 2 corresponding to the cross-hole structure 11. The cross-shaped boss 21 is embedded in the cross-hole structure 11. A U-shaped groove 22 is formed in one side wall of the main body block 2. A group of sliding grooves 25 are formed at the lower end of the main body block 2, and the sliding grooves 25 are arranged along the same horizontal line. The sliding pressing blocks 3 are respectively sleeved in the sliding grooves 25. One end of each sliding pressing block 3 extends out of the sliding groove 25 and extends into the U-shaped groove 22, and each sliding pressing block 3 can slide relatively along the sliding groove 25.

[0024] In this embodiment, the connection between the connecting rod 1 and the main body block 2 of the welding nozzle is set as a detachable four-axis adjustable cross-shaped structure, and then combined with the sliding pressing blocks 3 that can slide bidirectionally in the sliding grooves 25, the width between the two pressing head parts 33 can be effectively adjusted, realizing an increase in the laser light input amount, and the way that can be adjusted arbitrarily according to nickel sheets 4 of different lengths makes the welding nozzle have better practicability. Specifically, when it is necessary to adjust the direction of the main body block 2, the main body block 2 is removed from the connecting rod 1, the angle of the main body block 2 is rotated according to actual needs, and then the cross-shaped boss 21 of the main body block 2 is inserted into the cross-hole structure 11 of the connecting rod 1 for locking, so as to adapt to the pressing and welding of nickel sheets 4 of different lengths; when adjusting the width between the sliding pressing blocks 3, the sliding pressing blocks 3 can be manually slid to adapt to the pressing and welding of different nickel sheets 4.
