When it is necessary to release the limiting of the steel pipe, the second spring 202g can drive the moving frame 201c to return to the original position through the rebounding force of the second spring 202g, so that the clamping frame 102 can return to the original position and be separated from the steel pipe.

[0044] Specifically, the sliding disc 202f is inserted with a positioning column 202h on one side, and the positioning column 202h is movably connected with the sliding disc 202f.

[0055] When the mobile strip 203c is moved to drive the limiting block 203b to separate from the limiting groove X, the mobile disc 203e can be moved at this time. The movement of the mobile disc 203e can exert a squeezing force on the third spring 203f. The pull plate 203d is released when the mobile frame 201c returns to the original position. At this time, the force of the third spring 203f rebounding drives the limiting block 203b to engage with the limiting groove X, so that the mobile frame 201c can be limited again.

At this time, in order to prevent the bracket 101 from rotating, the user manually supports the bracket 101. Since the threaded sleeve and the threaded rod 103 are threadedly connected, rotating the threaded sleeve can drive the threaded rod 103 to move in the support sleeve 104, so that the height of the bracket 101 can be adjusted, thereby achieving the adjustment of the height of the bracket 101.

[0059] Then the bracket 101 is inclined, the bracket 101 is close to the steel pipe, prepares the clamping operation to the steel pipe, pushes the moving frame 201c and moves, the moving frame 201c moves and drives the sliding block 202e to slide in the chute Y on the side of the handle 106, the sliding block 202e moves and drives the sliding disc 202f to move, the sliding disc 202f moves and exerts the force of extrusion to the second spring 202g, the moving frame 201c moves and drives the limiting block 203b to move on the limiting groove X of the limiting plate 203a, the limiting block 203b is inclined, and the limiting groove X is one-way limited to the same, to prevent the moving frame 201c from returning to the original position, the moving frame 201c moves and drives the pull rope 201b to move, the pull rope 201b moves and drives the sliding column 201a to move, the sliding column 201a moves and drives the sliding bar 202a to slide in the bracket 101, the sliding bar 202a moves and drives the moving plate 202b to move, the moving plate 202b moves and exerts the force of extrusion to the first spring 202c, the sliding column 201a moves and drives the clamping frame 102 to move, until the clamping frame 102 contacts with the steel pipe and clamps the same, holds the handle 106 and pushes the trolley body 105 to move, the trolley body 105 drives the supporting sleeve 104, the bracket 101 and the steel pipe clamped by the clamping frame 102 to move together, and the steel pipe is transported to the designated position.

[0060] When the steel pipe is transported to the designated position, if the clamping of the steel pipe is released, the pull disc 203d is pulled, the pull disc 203d moves and drives the moving strip 203c to move, the moving strip 203c moves and drives the limiting block 203b to separate from the limiting groove X, the limiting of the moving frame 201c is released, then the rebounding force of the second spring 202g drives the moving frame 201c to return to the original position, the moving frame 201c returns to the original position and drives the pull rope 201b, the sliding column 201a and other related components to return to the original position in turn, the sliding column 201a returns to the original position and drives the clamping frame 102 to separate from the steel pipe, in the process, the moving plate 202b also returns to the original position under the rebounding force of the first spring 202c, the moving strip 203c drives the moving disc 203e to move and exerts the force of extrusion to the third spring 203f, when the pull disc 203d is released, the rebounding force of the third spring 203f drives the limiting block 203b to engage with the limiting groove X again, and the moving frame 201c is limited again, so as to be used next time.
