Secondly, a square groove-shaped slide groove 7 is opened on the side surface of the rotating plate 4, and the inner wall of the slide groove 7 is rotatably connected with a screw rod 8, and the outer surface of the screw rod 8 is screwed together with two plate-shaped clamping plates 5 by a ball screw, so that after adjusting the height and angle of the rotating plate 4, the screw rod 8 can be rotated by the staff, so that the two clamping plates 5 can slide relative to each other under the action of the ball screw, so as to clamp the photovoltaic panel and facilitate subsequent testing work.
[0022] Reference Figure 2 A driven wheel 9 is rotatably connected to the side surface of the sliding rod 3 through a rotating shaft, and the other end of the rotating shaft penetrates the sliding rod 3 and is fixedly connected to the side surface of the rotating plate 4, and a rotating column 10 is rotatably connected to the side surface of the sliding rod 3, and a driving wheel 11 is fixedly connected to the outer surface of the rotating column 10, and the driving wheel 11 and the outer surface of the driven wheel 9 are meshed with each other, so that the staff can rotate the rotating column 10 to drive the driving wheel 11 to rotate, and then drive the driven wheel 9 and the rotating shaft to rotate under the meshing action of the driving wheel 11 and the outer surface of the driven wheel 9, thereby driving the rotating plate 4 to rotate, so that the clamping plate 5 is parallel to the edge of the photovoltaic panel, so that when the two clamping plates 5 clamp the photovoltaic panel, they can fit with the surface of the photovoltaic panel to avoid damage to the photovoltaic panel.
