[0028] Several of the present applications are used at the same time to support the backfill pipe. The backfill pipe is placed in the arc groove of the arc support seat 32. The relative height of the two arc support seats 32 is adjusted by the first lifting mechanism 31 to adjust the inclination angle in the extension direction of the pipe to facilitate the transportation of the filler. The backfill pipe is then clamped by the clamping mechanism 33 to fix the backfill pipe to the present application. The fixing anchor 5 is used to fix the present application to the ground to prevent accidental movement after the present application supports the backfill pipe.

[0029] Specifically, an adjustment rail 2 is disposed on the top of the movable base 1 . The adjustment rail 2 extends in the front-rear direction and has two slide seats 21 slidably disposed on the top. The first lifting mechanism 31 is vertically disposed on the top of the slide seats 21 .

[0030] The adjustment rail 2 adjusts the distance between the two support mechanisms 3 to enhance the flexibility of the present application. A fixing bolt that penetrates the side wall of the slide 21 and contacts the adjustment rail 2 is provided on one side of the slide 21 to fix the slide 21 to the adjustment rail 2.

[0031] Specifically, the clamping mechanism 33 includes a mounting seat 331 arranged at the top of the arc-shaped support seat 32, a lifting groove is opened on the top of the mounting seat 331, the lifting groove extends to the inside of the arc-shaped support seat 32 and a lifting rod 332 is slidably arranged in the lifting groove, a spiral seat 334 is arranged on the top of the lifting rod 332, and a screw 335 is spirally penetrated by the spiral seat 334 along its left and right directions, a pressure plate 333 is rotatably arranged on one end of the screw 335 close to the center of the arc-shaped support seat 32, and a rotating handle 336 is arranged on the end away from the center of the arc-shaped support seat 32.

When the second lifting mechanism 52 drives the rotating motor 53 to descend, the rotating motor 53 drives the spiral cone 54 to rotate, so as to rotate the spiral cone 54 toward the ground, thereby enhancing the stability of the mobile base 1.

[0039] Preferably, there are two fixing anchors 5 , which are symmetrically arranged at the bottom of the mobile base 1 .

[0040] Preferably, a handle 6 is provided on the front of the mobile base 1 .
