[0030] The bottoms of the two clamping members 1 are both rotatably connected to the transmission members 2, the ends of the two transmission members 2 away from the clamping members 1 are both rotatably connected to the connecting members 4, and the ends of the two connecting members 4 away from the transmission members 2 are respectively rotatably connected to the two ends of the lifting seat 5.

[0031] By adopting the above technical solution, when in use, the motor 8 can control the rotation of the screw 9, and the screw 9 can drive the lifting seat 5 threadedly connected thereto to perform lifting movement when rotating. When the lifting seat 5 rises, the lifting seat 5 can respectively drive the two transmission members 2 through the two connecting members 4 to rotate with the connection between the transmission members 2 and the support seat 6 as the center of the circle. While the two transmission members 2 are rotating, they can synchronously drive the two clamping members 1 to allow the two clamping members 1 to rotate synchronously. According to the diameter of the steel pipe 13 to be clamped, the lifting and lowering of the lifting seat 5 is used to adjust the distance between the two clamping members 1, so that the two clamping members 1 can clamp the steel pipe 13 normally, and the two clamping members 1 are both arc-shaped on one side close to the steel pipe 13, which can increase the contact area between the two clamping members 1 and the steel pipe 13, thereby increasing the stability of the two clamping members 1 when clamping the steel pipe 13.

While the two transmission members 2 are rotating, they can synchronously drive the two clamping members 1, so that the two clamping members 1 rotate synchronously. According to the diameter of the steel pipe 13 to be clamped, the lifting and lowering of the lifting seat 5 is used to adjust the distance between the two clamping members 1, so that the two clamping members 1 can clamp the steel pipe 13 normally, and the two clamping members 1 are both arc-shaped on one side close to the steel pipe 13, which can increase the contact area between the two clamping members 1 and the steel pipe 13, thereby increasing the stability of the two clamping members 1 when clamping the steel pipe 13;

[0038] The multiple positioning bolts 11 sleeved in the slide grooves 10 of the two clamping members 1 can all move in the slide grooves 10. When the positioning bolts 11 need to be moved, the nuts of the positioning bolts 11 are loosened, and then the positions of the positioning bolts 11 are adjusted according to the diameter of the steel pipe 13 to be clamped, so that the curvature between the two positioning bolts 11 in the slide grooves 10 is the same as the curvature of the outer diameter of the steel pipe 13, and the curvature of the two clamping members 1 themselves can better fit with the outer wall of the steel pipe 13, thereby further increasing the stability of the steel pipe 13 and preventing the steel pipe 13 from shaking or tipping over; in addition, rubber rings 12 are sleeved on the outer sides of the multiple positioning bolts 11, and the multiple rubber rings 12 are directly fitted with the steel pipe 13.
