The arc-shaped cover 332 is arranged on the outer periphery of the mounting seat 32 and connected with the rotating sleeve 31 through the rotating shaft 331 penetrating the mounting seat 32. It can be understood that the number of protective cover bodies 33 should correspond to the number of welding points 50 of the workpiece to be welded, that is, each welding point 50 should be equipped with a corresponding protective cover body 33 for covering. In this embodiment, the protective cover body 33 comprises five, which are equally arranged on the outer periphery of the mounting seat 32. The rotating sleeve 31 can drive each protective cover body 33 to rotate synchronously relative to the mounting seat 32 to the lower side of the clamping tool 10 and cover the welding point 50 of the workpiece.

[0027] Before use, the workpiece to be welded 40 is fixed on the clamping tool and the welding base 20 respectively, and then the clamping tool 10 is driven to move downward so that the guide column 21 is aligned and the welding point 50 of the welding tool is aligned. Since the protective cover body 33 is arranged on the outer periphery of the mounting seat 32, it does not affect the installation of the workpiece to be welded 40 and the movement of the clamping tool 10.

[0028] In use, the rotating sleeve 31 is driven to rotate clockwise, at this time the rotating sleeve 31 can drive each protective cover body 33 to rotate synchronously relative to the mounting seat 32. During the rotation process, the arc-shaped cover 332 will rotate into the lower side of the clamping tool 10 and cover the corresponding welding point 50, as shown. Figure 6 As shown, the arc-shaped cover 332 is arranged on the inner side of the welding point 50, which can limit the welding slag in a limited area and prevent it from splashing, and also serves as a protective cover for the workpiece to prevent the welding slag from contacting the workpiece. After welding is completed, the rotating sleeve 31 is driven to rotate counterclockwise, at this time the rotating sleeve 31 can drive each protective cover body 33 to rotate synchronously relative to the mounting seat 32. During the rotation process, the arc-shaped cover 332 will rotate out of the lower side of the clamping tool 10 and reset to the outer periphery of the mounting seat 32, as shown. Figure 5 As shown, the finished workpiece is finally taken down.
