Through the setting of the protection mechanism, it can shield and protect between the welding part of the metal component and the operator's eyes, eliminating the operation of the operator wearing protective glasses and avoiding the discomfort caused by the operator wearing protective glasses for a long time;

[0024] The telescopic ends of the two telescopic mechanisms are fixedly connected to the side walls of the opposite mounting plates 5. The telescopic mechanism includes a first fixed plate 2 fixedly installed on the top of the mounting frame 1. An electric push rod 4 is fixedly installed on the side wall of the first fixed plate 2. The telescopic end of the electric push rod 4 is fixedly connected to the side wall of the opposite mounting plate 5;

[0025] Chutes 14 are respectively penetrated through the two mounting plates 5. Rotating rods 6 are respectively rotatably connected through the two mounting plates 5. A fixture 7 is fixedly installed at one end of the rotating rod 6. A rotating handle 8 is fixedly installed at the other end of the rotating rod 6. A rubber sleeve is sleeved on the handle of the rotating handle 8. Connection mechanisms are provided on the two rotating rods 6. The connection mechanism includes a circular block 17 fixedly installed on the rotating rod 6. Four clamping grooves 18 are opened on the circular block 17;

[0026] Limit plates 9 are fixedly installed on the side walls of both mounting plates 5. A limiting mechanism is arranged between the two limit plates 9. The limiting mechanism extends into the two connecting mechanisms and abuts against the inner top thereof. The limiting mechanism includes sliding rods 10 that are slidably connected through the two limit plates 9. At the top ends of the two sliding rods 10, clamping blocks 16 are fixedly installed. The two clamping blocks 16 both extend into the corresponding card slots 18 and abut against the inner top thereof. Between the bottom of each of the two clamping blocks 16 and the top of the corresponding limit plate 9, a spring 15 is fixedly connected. The two sliding rods 10 both penetrate through the corresponding sliding grooves 14 and are slidably connected thereto. A sleeve 11 is slidably connected between the ends of the two sliding rods 10.

[0027] The functional principle of the present utility model can be elaborated through the following operation method:

[0028] When welding metal parts is required, first, the operator fixes the two metal parts on the corresponding clamps 7 respectively. Then, the operator starts the two electric push rods 4 to extend. The two electric push rods 4 drive the two metal parts on the two clamps 7 to approach through the mounting plates 5. The two sliding rods 10 slide in the sleeve 11, so that the ends of the two metal parts abut against each other. Then, holding a welding torch, the operator welds the two metal parts through the protective mirror 13 on the second fixing plate 12. When welding other parts of the metal parts is required, the operator pulls the sleeve 11 downward. The sleeve 11 drives the two sliding rods 10 to move downward. The sliding rods 10 drive the clamping blocks 16 to move downward, so that the clamping blocks 16 are separated from the circular blocks 17. Then, the operator rotates the rotating handle 8 at one end. The rotating handle 8 drives the clamp 7 to rotate through the rotating rod 6. The clamp 7 drives the two metal parts to rotate by 90 degrees. When the metal parts are rotated to the position where welding is required, the operator releases the sleeve 11. The clamping blocks 16 slide into another card slot 18 under the action of the elastic force of the springs 15. The clamping blocks 16 fix the circular blocks 17, so that the two metal parts are fixed. Then, continue to weld the metal parts. After the welding of this part is completed, rotate the metal parts for welding according to the above method.

[0029] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
