[0028] Working principle: All electrical components appearing in this application are externally connected to a power supply and a control switch during use. After this utility model is installed, first check the installation and fixation as well as the safety protection of this utility model, and then it can be used; during use, the user rotates the sleeve 61, and through the external thread 71 and the internal thread 72, the sleeve 61 is rotationally installed on the fixed sleeve 4, so that the splash-proof sleeve 63 covers the outside of the welding head 5; then, by sliding the connecting rod 12, the distance between the connecting rod 12 and the connecting cylinder 13 is adjusted. When the appropriate distance is adjusted, the bolt 16 is tightened with the threaded hole 15, so that the bolt 16 enters the corresponding bayonet 14, and the distance between the connecting rod 12 and the connecting cylinder 13 is fixed. Under the pulling of the connecting rod 12 and the connecting cylinder 13, the corrugated pipe 62 is compressed and deformed, so as to adjust the distance between the splash-proof sleeve 63 and the sleeve 61 to match different welding heads 5.

[0029] Embodiment 2: Please refer to Figures 5 to 6 , a fully automatic welding robot, which is different from Embodiment 1 in that the fixing component 7 includes: a straight groove 73, an arc groove 74 and a slider 75. Two straight grooves 73 and two arc grooves 74 are symmetrically opened on the outer wall of the fixed sleeve 4. The straight grooves 73 and the arc grooves 74 correspond one by one. The arc groove 74 is located between the straight groove 73 and the connecting arm 3. The arc groove 74 communicates with the straight groove 73.

[0030] As a preferred solution, further, a side groove 8 is opened on the inner wall of one end of the arc groove 74 away from the straight groove 73. A spring 9 is welded on the inner wall of the side groove 8. A circular chuck 10 is slidably connected in the side groove 8. The circular chuck 10 is connected to the spring 9. A card slot 11 is opened on the outer wall of the slider 75. The circular chuck 10 is adapted to the card slot 11; the circular chuck 10 extends out of the side groove 8 in the normal state.

[0031] The user inserts the slider 75 into the straight groove 73 in alignment, and slides the slider 75 upward so that the slider 75 slides into the arc groove 74. Then, the sleeve 61 is rotated to make the slider 75 slide into the end of the arc groove 74. The slider 75 presses the circular chuck 10, causing the circular chuck 10 to press the spring 9 and enter the side groove 8 until the card slot 11 is aligned with the circular chuck 10. The spring 9 drives the circular chuck 10 to slide outward, making the circular chuck 10 enter the card slot 11, thereby fixing the sleeve 61 on the fixed sleeve 4 and making the splash guard 63 cover the outside of the welding head 5. Then, by sliding the connecting rod 12, the distance between the connecting rod 12 and the connecting cylinder 13 is adjusted. When the appropriate distance is adjusted, the bolt 16 is tightened with the threaded hole 15 to make the bolt 16 enter the corresponding bayonet 14, fixing the distance between the connecting rod 12 and the connecting cylinder 13. Under the pulling of the connecting rod 12 and the connecting cylinder 13, the corrugated pipe 62 is compressed and deformed, thereby adjusting the distance between the splash guard 63 and the sleeve 61 to match different welding heads 5.
