[0007] By rotating the nut cap and the support tube to make a threaded movement, the nut cap squeezes the block, and the square rod drives the clamping rod to move and contact the steel pipe, so that the steel pipe is clamped and positioned at multiple points, making it easy for the device to clamp steel pipes of different diameters while stably clamping the steel pipes.

[0008] Further, a rotating disk is welded to the right end of the bidirectional screw rod, and the rotating disk is in contact with the screw rod. By arranging the rotating disk, the bidirectional screw rod is easy to rotate.

[0009] Furthermore, a slide groove is provided inside the base, and the slide groove is slidably connected to the slide rod. The slide groove is provided to guide the movement of the slide rod.

[0010] Furthermore, the clamping mechanism includes a square rod, a clamping rod, a block, a spring, and a screw cover.

[0011] Furthermore, the clamping rod is a cylindrical structure and is made of metal. By rotating the screw cap and the support tube to make a threaded motion, the screw cap squeezes the block, and the square rod drives the clamping rod to move and contact the steel pipe, so that the steel pipe is clamped and positioned at multiple points, so that the device is convenient for clamping steel pipes of different diameters and the steel pipe is clamped stably.

[0012] Further, one end of the spring contacts the stopper, and the other end of the spring contacts the support tube. By arranging the spring, the stopper is easy to reset.

[0013] Furthermore, the screw cap contacts a stopper, and the stopper is a semicircular convex block structure. By providing the stopper, the square rod is easy to move. BRIEF DESCRIPTION OF THE DRAWINGS
