When the clamp is used for clamping the arc-shaped plate A, the arc-shaped convex surface can be downward or upward according to actual requirements, as shown in fig. 3 and 4. Before clamping, the orientation of the inclinable screw 400 is adjusted according to the curvature radius of the circular arc-shaped plate a, so that the inclinable screw 400 points to the center of the circle of the circular arc-shaped plate a, specifically, the upper slider 220 and the lower slider 320 are driven to move by the upper driving screw 210 and the lower driving screw 310, and as the upper rotating block 230 and the lower rotating block 330 are respectively rotatably arranged on the upper slider 220 and the lower slider 320, the inclinable screw 400 does translation and rotation, and finally points to the center of the circle of the circular arc-shaped plate a. It should be noted that the tiltable screw 400 is screwed with the upper through hole 231 but is slidably connected with the lower through hole 331, so that the tiltable screw 400 slides in the lower through hole 331 with the change of the distance between the upper through hole 231 and the lower through hole 331. Meanwhile, the tiltable screw 400 may be screwed to adjust the height of the first jaw 410, and finally the first jaw 410 may be rotated and clamped to the circular arc-shaped plate a.

The structure of the lower through-groove 121, and the arrangement and the function of the lower drive screw 310 and the lower guide bar 122 in the lower through-groove 121 are the same as those of the upper through-groove 111.
Still further, a lower transmission threaded hole 321 and a lower guide hole 322 are formed in the lower slider 320, the lower driving screw 310 is in threaded connection with the lower transmission threaded hole 321, and the lower guide rod 122 is in sliding connection with the lower guide hole 322. Here, a structure is specifically shown in which the lower slider 320 is in threaded transmission connection with the lower drive screw 310, and the lower slider 320 is in sliding connection with the lower guide rod 122.
Further, a vertical threaded through hole 130 is formed in the vertical support column 100, a vertical fixing screw 140 is connected to the vertical threaded through hole 130 in a threaded manner, and a second clamping jaw 141 is rotatably disposed at the top end of the vertical fixing screw 140. Before clamping, the vertical fixing screw 140 points to the center of the circle of the circular arc-shaped plate a, and the tiltable screws 400 at the two sides of the vertical fixing screw are symmetrical and also point to the center of the circle of the circular arc-shaped plate a, so that the circular arc-shaped plate a is clamped by the first clamping jaw 410 and the second clamping jaw 141.
