[0029] A ring plate is provided at the end of the gun barrel 5, and five groups of return spring columns 7 distributed in a ring shape are fixedly connected between the ring plate and the end of the welding head 4; wherein, the arrangement of each group of return spring columns 7 can ensure that the gun barrel 5 is at the front side of the welding head 4, and directly contacts and collides with the welding instead of it, and the elasticity of the return spring columns 7 themselves is used to offset the mutual pressure between them, so as to avoid the situation that the laser emitted by the laser gun head 1 deviates and affects the subsequent welding.

[0030] Five groups of slide grooves 41 that are opposite to each other and open at the front are provided on the inner side of the front end of the welding head 4, and a slide card 51 that matches the specifications of the slide groove 41 is fixedly installed on the outer wall of the gun barrel 5; wherein, the setting of the slide groove 41 and the slide card 51 can ensure that the gun barrel 5 slides back and forth on the inner side of the welding head 4, while ensuring its stability and avoiding the occurrence of rotation and shaking due to force.
