[0029] The swing rod 10 is fixedly connected with one end of an L-shaped rod 13 on both sides, and the other end of each L-shaped rod 13 is fixedly connected with an arc-shaped pressing plate 16, which is used to press the upper arc surface of the water meter.
[0030] The upper pressing plate 15 is a semi-circular ring, and the arc-shaped pressing plate 16 is an arc-shaped plate with a downward notch. Both the upper pressing plate 15 and the arc-shaped pressing plate 16 are rubber plates.
[0031] Further, in order to adapt to more types of water meters, the positioning block 9, the upper pressing plate 15 and the arc-shaped pressing plate 16 can be adjusted and replaced. For example, the middle positioning block 9 can be adjusted in position up and down by a top screw, and the upper pressing plate 15 and the arc-shaped pressing plate 16 can be screwed to facilitate replacement and disassembly, or customized according to different types of devices.
[0032] The lower end of the swing rod 10 is fixedly connected with the upper end of a connecting rod 8, the connecting rod 8 passes through a clamping groove at one end of a guide shaft 7, the guide shaft 7 penetrates the base 4, and two limiting shafts are fixed in the clamping groove at one end of the guide shaft 7. The connecting rod 8 passes through the two limiting shafts, and the guide shaft 7 can move forward and backward with the swing of the connecting rod 8. The lower end of the connecting rod 8 is rotatably connected with a fixed block 6, and the fixed block 6 is fixed on one side of the base 4.
[0033] The straight-line distance between the axes of the two limiting shafts is slightly greater than the width of the connecting rod 8.
