[0016] Such as Figure 1-2As shown in the figure, the utility model provides a detection tooling for a laser rangefinder detector, which includes a mounting base 7, a laser emission component 1 for emitting laser pulses, a transmitting antenna component 2 for laser beam expansion, an attenuation component 3 for attenuating laser energy, a receiving antenna component 4 for converging laser pulses, a detector mounting component 5, and a three-axis fixing seat 6. The laser emission component 1, the transmitting antenna component 2, the attenuation component 3, the receiving antenna component 4, the detector mounting component 5, and the three-axis fixing seat 6 are sequentially mounted on the upper surface of the mounting base 7 from right to left. The axes of the transmitting antenna component 2, the attenuation component 3, and the receiving antenna component 4 coincide. The detector mounting component 5 includes a structural member 5.1 and a circuit board 5.2 connected to the structural member 5.1 by screws. The circuit board 5.2 is used to process electrical signals and connect to an external display to display the detection results. The structural member 5.1 is mounted to the three-axis fixing seat 6 by screws. During detection, the detector 8 is mounted on the circuit board 5.2 for processing electrical signals by soldering, and the detector 8 is located at the laser exit of the receiving antenna component 4 after installation.

[0017] Preferably, the laser emission component 1 is connected to the transmitting antenna component 2 by screws, and the transmitting antenna component 2, the attenuation component 3, the receiving antenna component 4, and the three-axis fixing seat 6 are respectively mounted on the mounting base 7 by screws.

[0018] Preferably, as Figure 3 shown in the figure, the structural member 5.1 is formed by connecting two side walls through a connecting rod. The first side wall 5.11 is connected to the three-axis fixing seat 6 by screws. The second side wall 5.12 is attached to the side of the receiving antenna component 4 away from the attenuation component 3. The circuit board 5.2 is mounted on the second side wall 5.12.

The circuit board 5.2 is connected to an external display. Then, the detector mounting component 5 is mounted on the three-axis fixing seat 6. At this time, the detector 8 is at the laser exit of the receiving antenna component 4. Subsequently, the laser emission component 1 is started to emit laser pulses. The laser pulses are expanded by the transmitting antenna component 2, and then the laser energy is attenuated by the attenuation component 3. Finally, the laser pulses are converged by the receiving antenna component 4 onto the photosensitive surface of the detector 8 to be tested. The detector 8 to be tested converts the optical signal into an electrical signal and transmits it to the circuit board 5.2. The circuit board 5.2 processes the electrical signal and displays the detection result on the display.

[0020] The detector 8 to be measured is placed at the laser exit position of the receiving antenna assembly 4 by using the structural member 5.1.
