[0030] The top of the fixed bracket 1 is equipped with a first linear guide rail 4, and at least two sets of first sliders 41 are slidably mounted on the first linear guide rail 4.

[0031] A clamping assembly 5 for clamping pressure pipes is installed on the first slider 41 near the tail of the fixed bracket. The clamping assembly 5 includes a rectangular lower mounting plate 51, a rectangular upper mounting plate 52, screws 53, and round nuts 54. The lower mounting plate 51 is installed on the first slider 41 near the tail of the fixed bracket 1. Two screws 53 are vertically fixed to the top ends of both ends of the lower mounting plate 51. A through hole 521 is opened at each end of the upper mounting plate 52. The top end of the screw 53 is inserted into the through hole 521 from bottom to top. A round nut 54 is screwed onto each screw 53. Three handles 541 arranged in a circular array are fixed to the outside of the round nut 54. A set of V-shaped wheels 9 are installed at the middle of the top end of the lower mounting plate 51 and the middle of the bottom end of the upper mounting plate 52.

[0032] Each screw 53 is fitted with a compression spring 55, which is clamped between the upper mounting plate 52 and the lower mounting plate 51, so that the upper mounting plate 52 is in a suspended state without the pressure of the round nut 54, so that the clamping assembly 5 can be clamped on the pressure pipe.

[0033] The remaining first slider 41 is equipped with a first support assembly 6 for supporting the pressure pipe. The first support assembly 6 includes a rectangular first mounting plate 61, and a set of V-shaped wheels 9 are mounted on the top of the first mounting plate.
