There are two magnetic bases 101, which have switches on them. When started, the entire bracket can be adsorbed to the rod near the scaffolding upright 5 by magnetic force. The magnetic base 101 and the base rod 103 are connected to each other through the ball joint 102, and the ball joint 102 can realize free rotation in all directions; the base rod 103, the connecting seat 104, the horizontal rod 106 and the horizontal rod 2 108 are connected to each other through the rotating shaft 105, and the rotating shaft 105 can only realize the rotation within the plane of the rotating shaft 105. A level 107 is provided on the side of the horizontal rod 106 to facilitate the leveling of the horizontal rod 106.

[0028] like Figure 1-4 As shown, the clamping device 3 is provided with two, which can adjust and fix the relative position of the top rod extensometer 4 and the scaffolding upright pole 5. When in use, the top rod extensometer 4 passes through the upright frame 304 of the clamping device 3, and the contact head of the top rod extensometer 4 is placed on the scaffolding upright pole 5 whose deformation is to be measured, so that the displacement deformation of the upright pole in two horizontal directions during the construction process can be measured.

[0029] like Figure 1-6 As shown, the limiting device 2 includes a circular rod 201, a sliding buckle 202, and a pin 203. The circular rod 201 is a hollow arc-shaped sliding track groove, and the circular rod 201 is connected to the end of the horizontal rod 108 of the fixing device 1 through a rotating shaft 105. The upper part of the sliding buckle 202 is an L-shaped iron sheet, and the lower part is a flat iron sheet, which is connected and fixed in the middle by a cylindrical iron block, and the cylindrical iron block is located in the hollow groove of the circular rod 201, so that the sliding buckle 202 can slide freely in the hollow groove of the circular rod 201. There are two sliding buckles 202, and the two sliding buckles 202 are arranged at intervals. When the sliding buckle 202 moves to a suitable position, the sliding buckle 202 is fixed by tightening the side wall of the circular rod 201 through the pin 203.

The upper part of the stand 304 has a round hole, and the fastening screw 305 passes through the upper round hole of the stand 304. The stand 304 and the fastening screw 305 cooperate to fix the top rod extensometer 4.

[0034] 2.
