[0016] Furthermore, a limiting plate is provided on the end face of the connecting seat near the base rod B. The limiting plate has an arc-shaped surface that conforms to the shape of the end of the base rod B. After the base rod B rotates a certain angle, it abuts against the limiting plate.

[0017] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:

[0018] This invention enables the instrument to perform origin calibration, making the instrument more accurate in use;

[0019] Base rod A and base rod B are hinged together. Base rod A can be rotated 180° at the hinge to achieve folding. Base rod B is hinged together with the connecting seat. Base rod B can be rotated 90° at the hinge to achieve storage.

Detailed Implementation

[0028] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0029] like Figures 1-6 As shown in the figure, this utility model provides a foldable origin coordinate bracket, including a base rod A1, a base rod B2 and a connecting seat 3 connected in sequence. The coordinate origin 4 is provided above the end of the base rod A1 away from the base rod B2. The connecting seat 3 is fixed to the bottom of the base plate 15 by bolts.

[0030] The maximum rotation angle between the base rod A1 and the base rod B2 is 180°, and the maximum rotation angle between the base rod B2 and the connecting seat 3 is 90°.

[0031] A pivot pin 5 is provided at the hinge joint between the base rod A1 and the base rod B2. The base rod A1 can rotate 180° along the axis of the pivot pin 5. The pivot pin 5 is sequentially inserted into the thrust washer A9 and the copper sleeve A8 in the vertical direction. The thrust washer A9 is located between the two end faces of the base rod A1 and the base rod B2. The copper sleeve A8 is embedded and fixed inside the base rod A1.

[0032] The bottom end of the pivot pin 5 is connected to the fastening screw 6, and a washer 7 is installed at the connection end face.

[0033] The connecting seat 3 is provided with a rotating shaft 10. The base rod B2 can rotate 90° along the axis of the rotating shaft 10. The rotating shaft 10 is sequentially inserted into the thrust washer B12 and the copper sleeve B11 in the vertical direction.
