In this embodiment, since the frame is substantially rectangular, the cross section of the fixing notch 124 is substantially right-angled, so that the corners of the frame can be snapped into the fixing notch 124, thereby fixing the frame.
The cross section of the fixing notch 124 is substantially direct, so that the corners of the rectangular frame can be completely attached to the fixing notch 124, and the frame can be positioned outside the frame under the matching of the plurality of fixing members 122.
In the present embodiment, the fixing member 122 is slidably connected to the base plate 110. The fixing member 122 slidably coupled to the base plate 110 can adjust a distance between the fixing member and the bezel, that is, the size of the fixing groove can be adjusted to adapt to different sizes of the bezel.
When the frame is installed, the first positioning member 130 is used as an installation reference, one wide side of the frame abuts against the first positioning member 130, and the distance between the fixing member 122 and the frame is adjusted, so that the plurality of fixing members 122 can fix the frame from the outer side of the frame. Then, the position of the second positioning member 140 is adjusted, so that the second positioning member 140 can fix the frame from the inner side of the other broad side.
In this embodiment, the fixing assembly 120 further includes a stopper 126, and the stopper 126 is disposed between two adjacent fixing members 122 and forms a fixing groove together with the plurality of fixing members 122.
Because the frame is the rectangle, the length of frame is longer relatively, in order to improve the fixed effect to the frame, sets up stop part 126 on the length direction of frame, can avoid the frame because the problem that the frame that length overlength leads to warp.
Because the frame is rectangular, the number of the stop parts 126 is at least two, and the two stop parts 126 are respectively arranged at the outer sides of the two long edges of the frame, so that the long edges of the frame are positioned.
Also, since the stopper 126 is disposed outside the long side of the bezel, the length of the stopper 126 should be substantially equal to the length of the bezel.
In this embodiment, the stopper 126 includes a stopping portion 1262 and a plurality of connecting portions 1264, the plurality of connecting portions 1264 are disposed on the stopping portion 1262 at intervals, and the stopping portion 1262 is fixedly connected to the bottom plate 110.
Both the stopper portion 1262 and the connecting portion 1264 are in contact with the long side direction of the frame, so that the positioning effect on the frame can be improved.
In this embodiment, the welding device 100 further includes a connecting member 150, the connecting member 150 is installed on the bottom plate 110, and the second positioning member 140 is fixedly connected to the connecting member 150 under the condition that the second positioning member 140 slides relative to the bottom plate 110 to abut against the frame.
