[0002] With the development of the security market, laser beam detectors play a crucial role in security applications. Laser beam detectors offer advantages such as long detection range, concentrated energy, and small divergence angle, making them usable even in adverse weather conditions like rain and fog. However, beam detectors require optical path calibration before use. This calibration is quite complex, especially when there are many optical paths, requiring calibration of multiple layers individually. This process is difficult and inefficient. Utility Model Content

[0004] Therefore, the technical solution of this utility model is: a multi-optical path adjustment device, including a base, an adjustment seat, a first adjustment plate, and a second adjustment plate. The base has a C-shaped structure and a groove at the front end to accommodate the adjustment seat. Multiple optical path generators are rotatably mounted on the adjustment seat. A spherical adjustment component is provided on the outside of each optical path generator, and an adjustment rod is provided at the rear end of each optical path generator. An adjustment groove is provided inside the adjustment seat, and the first and second adjustment plates are placed in the adjustment groove. The first adjustment plate has several vertically arranged first sliding grooves, and the second adjustment plate has several horizontally arranged second sliding grooves. The adjustment rod passes through the first and second sliding grooves in sequence.

Multiple first springs 6 are provided between the back of the adjustment seat 2 and the base 1. The base 1 has spring mounting slots, and the first springs 6 are placed in these slots. The first springs 6 exert an outward force on the adjustment seat 2, causing it to abut against the first set screws 5. The first set screws 5 are located at the four corners of the adjustment seat 2. The tilt of the adjustment seat 2 can be adjusted using the first set screws 5, thereby changing the optical path direction of the optical path generator on the adjustment seat 2.

The second set screw 8 adjusts the left and right positions of the first adjusting plate 3. The adjusting rod 72 at the rear end of the optical path generator 7 is placed in the first sliding groove 31. After being driven by the first sliding groove 31, it moves horizontally along the second sliding groove 41, so that the optical path generator 7 rotates horizontally.

[0022] The adjusting seat 2 has a second adjusting hole 24 below it, and the base 1 has a through hole below it. The third set screw 9 passes through the through hole and is threaded into the second adjusting hole 24.
