A through hole penetrating through the upper and lower surfaces of the rocker arm 11 is formed in the center of the groove, and an internal thread is formed in the through hole. The adjusting screw 15 passes through the rocker arm 11 through the through hole and is threadedly connected with the internal thread in the through hole. The top of the adjusting screw 15 is movably connected with a lifting strip 14, the bottom of the adjusting screw 15 is provided with a knob 16, and the lifting strip 14 is lifted on the surface of the rocker arm 11 by rotating the knob 16.

By providing the lifter bar 14, it is possible to adapt to a weldment having a more specific shape, and the groove shape described above is the same as the lifter bar 14, and when it is not necessary to use the lifter bar 14 for assistance, the lifter bar 14 can be entirely entered into the groove by rotating the knob 16, and after the lifter bar 14 is entered into the groove, the upper surface thereof is flush with the upper surface of the rocker arm 11.

The specific working process and working principle are as follows:

firstly, the angles of two rocker arms 11 are adjusted according to the welding angle of a weldment, the rocker arms 11 with the adjusted angles are fixed with the back plate 1 through locking screws 10 and locking blocks 17, and then whether the lifting strips 14 are used for auxiliary fixing is selected according to needs. Then the weldment is placed on the surfaces of the two rocker arms 11, the pressing position of the pressing block 9 is determined by rotating the rotating block 5, finally the weldment is pressed by the pressing block 9 by rotating the driving rod 3, and finally welding is carried out after fixing is finished.

Example 2:

as shown in fig. 5, the present embodiment is different from embodiment 1 in that: in this embodiment, the rotating block 5 rotatably connected to the surface of the slider 6 is eliminated, and a through hole with threads on the inner surface is formed in the slider 6 at a position along the upper and lower sides of the slider 6, and the lifting screw 4 passes through the slider 6 from the top to the bottom and is threadedly connected to the slider 6.
