Anchor rods are now used not only in mines, but also in engineering technology to reinforce the main body of slopes, tunnels, and dams. During tunnel excavation, an inappropriate anchor rod angle will greatly reduce the support strength of the surrounding rock. Existing anchor rod angle measurement devices do not have lighting functions. In dim tunnels, it is difficult for workers to see the scale lines clearly when measuring the anchor rod angle, which can easily cause reading errors, resulting in inaccurate angle data.

A pointer is rotatably arranged at the center of the semicircular scale, and the pointer rotates under the action of its own weight, so that the angle can be directly read through the position of the scale line indicated by the pointer, thereby realizing the measurement of the anchor rod angle, and the operation is simple. At the same time, when reading, the light emitted by the luminous ball is emitted from the arc-shaped transparent plate, which can play a certain lighting role in the dim alley, so that the surveying personnel can clearly see the scale line and read the number, so that the measured anchor rod angle data is more accurate.
[0007] Furthermore, the luminous balls are distributed in sequence along the arc direction of the arc-shaped cavity, the luminous balls are bonded into the arc-shaped cavity, and the luminous balls are of the light-storing and light-emitting type.
[0008] Furthermore, the fixing rod is arranged horizontally and located in the radial direction of the semicircular scale.
[0009] Furthermore, an internal threaded hole is provided in the fixing cap, and the fixing cap is threadedly connected to the end of the anchor rod through the internal threaded hole.
[0010] Furthermore, the cross section of the fixing cap is hexagonal.
