This prior art can adjust the workpiece by rotating the second rotating handle, and has self-locking properties. After the adjustment is completed, the device will automatically lock, and the workpiece can be fixed in the middle position of the device by rotating the first rotating handle, which can quickly position the workpiece, and the height of the device can be adjusted by rotating the rotating thread ring.

[0004] However, when the prior art is actually used, it is necessary to rotate various handles to adjust the workpiece fixation, which is time-consuming to use and affects the efficiency of the welding process. In addition, this type of fixing device cannot remove the odor during the welding process. During the use of the welding machine, smoke and gas will be generated due to the welding materials and the welding process. These smoke and gases may contain harmful substances, such as carbon monoxide, nitric oxide, hydrogen chloride, etc., which are potentially harmful to human health.

[0005] Therefore, the present application provides a fixing device for a welding machine to solve the above technical problems. Utility Model Content
