A threaded rod B8 is rotatably connected to the bottom end of the inner surface of the support frame 1, allowing the threaded rod B8 to rotate along the bottom end of the inner surface of the support frame 1. A hinge B16 is threadedly connected to the outer surface of the threaded rod B8, allowing the threaded rod B8 to move laterally due to the threaded connection. The hinge B16 is hinged to the left side of the inner surface of the planar surveying rod 2 via a hinge rod A10, allowing the planar surveying rod 2 to move laterally along the inner surface of the support frame 1. The front end is unfolded. There are two sets of planar surveying rods 2, which can measure the angle of the corner when unfolded. The rear end of the outer surface of the support frame 1 is fixedly connected to the positioning rod 4, which provides fixed support for the positioning rod 4. The inner surface of the positioning rod 4 is provided with a telescopic component, which can keep the positioning rod 4 on the diagonal of the corner when measuring corners at different angles. The left side of the threaded rod A7 and threaded rod B8 are provided with anti-slip rotating handles, which makes it easier to rotate the threaded rod A7 and threaded rod B8.

[0040] Reference Figure 2 , Figure 9 - Figure 10The telescopic assembly comprises the gear 9, the toothed plate 14 and the telescopic rod A6. The outer surface of the gear 9 is rotationally connected with the middle part of the inner surface of the positioning rod 4, so that the gear 9 can rotate along the middle part of the inner surface of the positioning rod 4. The outer surface of the toothed plate 14 is slidably connected with the inner surface of the positioning rod 4, so that the toothed plate 14 can move laterally along the inner surface of the positioning rod 4. The inner surface of the toothed plate 14 is engaged with the outer surface of the gear 9, so that the gear 9 can drive the toothed plate 14 to move laterally when the gear 9 rotates.
