The first rod sleeve 19 is fixed to the mounting plate 3, and the first rod body 20 is movably inserted into the first rod sleeve 19, allowing it to slide along the first rod sleeve 19. The first lead screw 21 is rotatably mounted on the first rod body 20 and forms a threaded engagement with the first rod sleeve 19. Rotating the first lead screw 21 allows the first rod body 20 to extend or retract relative to the first rod sleeve 19.

[0038] The structure of the second telescopic rod 5 is the same as that of the first telescopic rod 4, except that the length is different. The second telescopic rod 5 is perpendicular to the first telescopic rod 4, and the fixed end of the second telescopic rod 5 is connected to the movable end of the first telescopic rod 4, so that the movable range of the second telescopic rod 5 is not only limited to its own telescopic, but also moves with the movable end of the first telescopic rod 4, so that the guiding position can be adjusted in two directions, and the flexibility of adjustment is increased.

[0039] The adjusting disc 6 is fixed to the movable end of the second telescopic rod 5, and serves as the support and adjustment basis of the swing plate 7. The swing plate 7 is connected to the adjusting disc 6 through an adjusting mechanism, and the inclination angle of the swing plate 7 on the adjusting disc 6 can be adjusted, so that the position of the guide wheel set 8 can be further adjusted according to the size of the welding wire disc.

[0040] As shown in Figure 2 , the guide wheel set 8 is arranged at one end of the swing plate 7, and is composed of a positioning frame 18 and two guide wheels. Figure 3 As shown in , the positioning frame 18 is rotatably installed on the swing plate 7, so that the guide wheel set 8 can be adjusted in direction as needed. The two guide wheels are rotatably installed on the positioning frame 18, and are used to guide the welding wire to smoothly pass between the two guide wheels. The guide wheels are provided with recesses in circular arc cross section, and the edges of the wheel surfaces of the two guide wheels are tangent, so that the welding wire can be better fitted, the friction and wear are reduced, the wire feeding efficiency is improved, and the welding wire is prevented from being separated from the two guide wheels.

[0041] Through the above arrangement, the front and rear positions and the left and right positions of the guide wheel set 8 can be adjusted by adjusting the lengths of the first telescopic rod 4 and the second telescopic rod 5, and the position and direction of the guide wheel can be further adjusted in detail by adjusting the angle and position of the swing plate 7 on the adjusting disc 6, so as to reduce the friction between the welding wire and the wire inlet 2, and enable the guide wheel set 8 to adapt to welding wire discs of different diameters.
