[0019] See also Figures 1 to 3 Preferably, a plurality of vertical rods 12 are provided below the fixed plate 1 of the utility model, and the plurality of vertical rods 12 are all slidably connected to the upper magnetic plate 11 .

[0020] See also Figures 1 to 3 In addition, the upper magnetic plate 11 of the utility model is rotatably connected with a cross bar 5, and a cam 6 is provided at the end of the cross bar 5, and two sides of the cam 6 are respectively abutted against the upper gear plate and the fixed plate 1.

[0023] Working principle: The strain gauge is clamped between the left clamping jaw 3 and the right clamping jaw 31. At this time, the main elastic member 33 is forced to contract, and the upper magnetic plate 11 below the fixed plate 1 is placed on the lower magnetic plate 41. The upper magnetic plate 11 and the lower magnetic plate 41 are adsorbed on each other to achieve a quick connection. The upper magnetic plate 11 is rotatably connected with a cross bar 5, and a cam 6 is provided at the end of the cross bar 5. At this time, the minimum diameter of the cam 6 abuts against the fixed plate 1;

[0024] The support column 4 is set as a telescopic rod. By adjusting the height of the support column 4, the fixed plate 1 with several strain gauges is driven to abut against the measuring position of the pier. At this time, the strain gauge is brushed with fixing glue. The cross bar 5 is rotated to drive the maximum diameter of the cam 6 to abut against the fixed plate 1 to ensure that the strain gauge on the fixed plate 1 is tightly abutted against the pier. After the fixing glue is dry, the cross plate 2 is pulled to facilitate the left clamp 3 to detach from the strain gauge, ensuring that the support device quickly detaches from the strain gauge to facilitate the stress monitoring of the pier.
