A second connecting arm 55 is installed at the top, and a clamping claw seat 56 is installed at the top of the second connecting arm 55 through a pin shaft. A clamping claw 57 is fixedly installed on the clamping claw seat 56, and a third tightening knob 58 is installed on one side of the clamping claw 57. The sliding clamp 5 can be used to clamp the edge of the automobile pillar. Since the automobile pillar is an irregular shape, the sliding clamp 5 can slide at any position on the sliding rod 41, and then the sliding clamp 5 is fixed by the first tightening knob 51. A rotating shaft 53 is provided between the first connecting arm 52 and the second connecting arm 55, so that the first connecting arm 52 and the second connecting arm 55 can be adjusted at any angle, and then fixed by the second tightening knob 54.
