The upper end of the connecting base 1 is connected to a main frame 2 by bolts. The connecting base 1 and the main frame 2 are separated to facilitate welding of supports of different specifications. Supports of different specifications have different volumes. Supports of small volume can directly use the main frame 2, and supports of large volume can increase the height of the main frame 2 by connecting the base 1.

[0020] The connecting plate 6 is connected to the fixing plate 8 by bolts, and a first positioning seat 9 is connected to the end face of the fixing plate 8. A connecting rod 10 is connected to the end of the first positioning seat 9, and a mounting shaft structure is provided at the end of the connecting rod 10. A second positioning seat 11 is inserted and provided on the outer side of the mounting shaft structure. An internal thread is provided at the end of the mounting shaft structure, and an end connecting bolt 12 is threadedly connected to the inner side of the internal thread. A clamping plate is provided between the end connecting bolt 12 and the second positioning seat 11. The support of the excavator is set on the outer side of the connecting rod 10 and positioned by the first positioning seat 9. The second positioning is performed at the other end of the support by the second positioning seat 11, and the clamping plate is clamped by the end connecting bolt 12, thereby clamping the second positioning support to complete the fixation.

[0021] The motor is electrically connected to a control panel 4 through a wire. An emergency stop button, a start button, and a stop button are provided on the control panel 4. The start button is used to control the motor to rotate. Workers can choose to weld while rotating, or they can choose to rotate a certain angle and stop before welding, and then rotate again. There are two operating modes.

[0022] Connecting holes 7 are provided on the end surface of the connecting plate 6, and there are three groups of connecting holes 7. Each group of connecting holes 7 is evenly distributed in a circle with equal angles. The circumferential radii of the three groups of connecting holes 7 are different.
