Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and by embodiment, and following examples are to explanation of the present utility model and the utility model is not limited to following examples.
Embodiment.
Referring to Fig. 1 to Fig. 6, straight tube 1, preceding straight tube fixed mount 2, back straight tube 3, back straight tube fixed mount 4, tong-test ammeter stand 5, cylinder 6, piston rod 61, cylinder fixed mount 7, line slideway 8, flexible coupling 9 and gas meter, flow meter 10 before the clamp device that is used for the gas meter, flow meter detection of present embodiment comprises.Wherein, back straight tube 3 is fixed on the tong-test ammeter stand 5 by back straight tube fixed mount 4, preceding straight tube 1 is fixed with preceding straight tube fixed mount 2, line slideway 8 is arranged on the tong-test ammeter stand 5, preceding straight tube fixed mount 2 matches with line slideway 8, before straight tube fixed mount 2 be slidingly connected by line slideway 8 and tong-test ammeter stand 5, thereby straight tube 1 can slide along line slideway 8 before making, and can offset direction when straight tube 1 compresses before being arranged so that of line slideway 8.
