[0019] When the present invention is in use, in the fixed component, when the blade to be welded is welded, the device moves to the required welding position, the engine starts, and drives the output shaft to run, the output shaft will drive the arc surface rotating plate to run, the arc surface rotating plate will drive the arc surface column to run, when the arc surface column runs, it will drive the connecting arc plate to run, the connecting arc plate will drive the pulling column on the inner wall of the other end to run, the pulling column will drive the push plate to slide along the surface of the push groove plate, and at the same time the push plate will also push the telescopic bottom plate to telescope and increase the force bearing area, when the telescopic bottom plate is telescoped, it will also drive the surface telescopic plate and the end telescopic plate to telescope and run. The surface telescopic plate and the end telescopic plate will protect the device. At the same time, when the telescopic bottom plate is telescoped, the outer tooth plate and the inner tooth plate on the inner wall will be driven to move relative to each other. The outer tooth plate and the inner tooth plate drive the internal threaded tooth column to rotate along the inner wall of the fixed connecting plate through the meshing action. The internal threaded tooth column drives the external threaded column to slide up and down along the inner wall of the fixed connecting plate through the thread action of the inner wall. When the external threaded column slides up and down, it will drive the adsorption plate to move up and down. Finally, the adsorption plate contacts the ground, increases the force points of the device, and fixes the position, so that the device can operate safely during welding.

[0020] When the present invention is in use, when the blade to be welded is placed between the fixed clamping plate and the sliding clamping plate in the clamping component, the control plate is started to drive the horizontal threaded shaft to operate, and the horizontal threaded shaft drives the internal threaded U-plate to slide along the surface of the U-plate groove through the action of the thread. When the internal threaded U-plate operates, it will drive the clamping plate groove plate to operate, and the clamping plate groove plate will drive the sliding clamping plate to operate. At the same time, the surface of the clamping plate groove plate and the inner wall of the fixed clamping plate slide and operate. After operating to the required position, the blade is finally clamped and fixed. At the same time, when the fixed clamping plate and the sliding clamping plate are close to each other, an elastic effect is generated on the spring plate, and the blade is elastically protected by the elastic force generated by the spring plate, so that the device can be operated. In order to better protect the device, at the same time, the lifting rod and the lifting column operate to adjust the height of the blade, drive the protection slot plate to operate, the protection slot plate will drive the protection spring to operate, the protection spring will drive the collision plate to operate, when the blade is welded, if it is tilted, it will collide with the collision plate, the collision plate will squeeze the protection spring, and the protection spring will buffer and protect it through its own elastic force. At the same time, when the protection slot plate is running, it will drive the telescopic rotating column to telescope and operate, and at the same time, the other end of the telescopic rotating column will rotate along the surface of the end telescopic plate. The telescopic rotating column is connected to the end telescopic plate, and when the protection slot plate is running, it can better protect the device.

[0021] When the present invention is in use, in the adjustment component, after the blade is fixed in position, when welding is performed, if angle adjustment is required, the output shaft will drive the adjustment plate to operate, and when the adjustment plate operates, it will drive the lifting welding gun on the surface to operate, and the rotation of the adjustment plate will drive the angle adjustment of the lifting welding gun. When the position is adjusted, the arc rope collection box operates, driving the arc rope to slide along the inner wall of the slide plate to perform the retracting and releasing effect. When collecting, the arc rope will drive the lifting welding gun to slide along the surface of the welding gun slide groove. After running to a certain position, welding is performed. When the position runs excessively, it will collide with the telescopic slider, and the telescopic slider will collide with the reset spring. The reset spring will generate elastic force, and finally react to the lifting welding gun. When the arc rope is relaxed, the auxiliary lifting welding gun returns to its original position. At the same time, when the lifting welding gun runs along the welding gun slide groove, it will drive the elastic sleeve plate to rotate along the surface of the fixed shaft, and elastic deformation will occur at the same time, together with the telescopic slider, the position of the lifting welding gun is operated to assist, so that the blade can be better welded.

The surface telescopic plate 10 and the end telescopic plate 11 will protect the device. At the same time, when the telescopic bottom plate 7 is telescoped, the outer tooth plate 33 and the inner tooth plate 34 on the inner wall will be driven to move relative to each other. The outer tooth plate 33 and the inner tooth plate 34 drive the internal threaded tooth column 30 to rotate along the inner wall of the fixed connecting plate 29 through the meshing action. The internal threaded tooth column 30 drives the external threaded column 31 to slide up and down along the inner wall of the fixed connecting plate 29 through the thread action of the inner wall. When the external threaded column 31 slides up and down, it will drive the adsorption plate 32 to move up and down. Finally, the adsorption plate 32 contacts the ground, increases the force points of the device, and fixes the position, so that the device can operate safely during welding.

When collecting, the arc rope 66 will drive the lifting welding gun 6 to slide along the surface of the welding gun slide 62. When it runs to a certain position, it is performed. During welding, when the position is excessively moved, it will collide with the telescopic slider 63, and the telescopic slider 63 will collide with the reset spring 64. The reset spring 64 will generate elastic force, which will eventually react on the lifting welding gun 6. When the arc rope 66 is relaxed, the lifting welding gun 6 will be assisted to return to its original position. At the same time, when the lifting welding gun 6 moves along the welding gun slide 62, the elastic sleeve 69 will be driven to rotate along the surface of the fixed shaft 68, and elastic deformation will occur at the same time. Together with the telescopic slider 63, the position movement of the lifting welding gun 6 will be assisted, so that the blades can be better welded.
