[0023] Based on the above structure, the mounting plate 1 is brought close to the pipeline, and one of the arc-shaped clamping blocks 5 is rotated along the corresponding rotating shaft 10. Under the meshing action of the gear 4, the two arc-shaped clamping blocks 5 are synchronously rotated in opposite directions and can be moved away from each other. Under the torsion force of the torsion spring 9, the two arc-shaped clamping blocks 5 are brought close to each other and form a clamping effect on the pipeline, thereby achieving rapid clamping. When it is necessary to clamp a pipeline with a larger diameter, the extension rod 6 can be slid out along the sliding hole 14 and fixed by the limit unit, so that the length of the arc-shaped clamping block 5 is lengthened, so that a pipeline with a larger diameter can be clamped, which is convenient and quick to use.

[0024] like Figure 3 As shown, the limiting unit includes a tooth block 7, a side of the arc-shaped clamping block 5 away from one end of the rotating shaft 10 is provided with an avoidance hole, an elastic rod 13 is installed on one side of the arc-shaped clamping block 5 at the position of the avoidance hole, the tooth block 7 is installed at one end of the elastic rod 13, a groove is provided on one side of the extension rod 6, a rack 11 is installed in the groove, one side of the tooth block 7 is plugged and matched with the rack 11, after the extension rod 6 slides to a suitable position, the tooth block 7 approaches one side of the extension rod 6 under the elastic action of the elastic rod 13 and is plugged and matched with the rack 11, thereby limiting the movement of the extension rod 6 and realizing the limiting function.

[0025] like Figure 3 As shown, a pull block 12 is installed on one side of the tooth block 7. The setting of the pull block 12 facilitates pulling the tooth block 7 to separate it from the rack 11 and release the limit.

[0026] like Figure 1 and 4 As shown, a suction cup 8 is installed on one end of the extension rod 6 away from the arc-shaped clamping block 5 through a rotating assembly. Through the setting of the suction cup 8, when clamping a pipe with a larger diameter, the suction cup 8 can be rotated to the concave side surface of the arc-shaped clamping block 5, so that the suction cup 8 is adsorbed on the surface of the pipe, thereby increasing the clamping stability.

The suction cup 8 is installed at one end of the sleeve 20, and a pulling unit is installed at one end of the suction cup 8. The limit block 22 slides along the rotating rod 17 with the sleeve 20. When the sleeve 20 is away from the fixing block 15, the limit block 22 and the limit groove 19 are separated. The pulling unit can pull the sleeve 20 close to the fixed block 15 and insert the limit block 22 into the limit groove 19 to achieve fixation.

[0029] like Figure 4 As shown, the pulling unit includes a tension spring 21, which is located inside the sliding sleeve 20, one end of the tension spring 21 is installed at one end of the rotating rod 17, and the other end of the tension spring 21 is installed on one side of the suction cup 8. The tension of the tension spring 21 pulls the sliding sleeve 20 close to the fixed block 15, and inserts the limit block 22 into the limit groove 19 to achieve fixation.

Under the torsion force of the torsion spring 9, the two arc-shaped clamping blocks 5 approach each other and form a clamping effect on the pipeline, thereby achieving rapid clamping. When it is necessary to clamp a pipeline with a larger diameter, the extension rod 6 can be slid out along the sliding hole 14 to lengthen the length of the arc-shaped clamping block 5, and the limit is achieved by plugging and matching the tooth block 7 and the rack 11, so that the pipeline with a larger diameter can be clamped, which is convenient and quick to use.

[0032] By rotating the rotating rod 17 through the rotating shaft 18, the rotating rod 17 can be rotated 180° and the suction cup 8 can be rotated to the concave side of the arc-shaped clamping block 5. The tension spring 21 can pull the sliding sleeve 20 close to the fixed block 15, and the limit block 22 is inserted into the limit groove 19 to fix the position of the suction cup 8. Therefore, when clamping a pipe with a larger diameter, the suction cup 8 can be rotated to the concave side of the arc-shaped clamping block 5, so that the suction cup 8 is adsorbed on the surface of the pipe, thereby increasing the clamping stability.
