[0024] A quick connecting locking device of a laser probe, the overall structure of the laser probe is as shown in Figure 1 , the upper end of the main body is provided with four insertion ears 7, the overall structure is in a cylindrical structure, the present application is designed to utilize the characteristics of the four insertion ears 7 to design a connecting joint capable of quick connection or separation, the explosion structure diagram of the overall connecting joint is as shown in Figure 2 , it is mainly composed of a probe card 1 as shown in Figures 11-12 , a cover plate 2 as shown in Figures 6-9 , a reset spring 3, a rotating disc 4 as shown in Figure 10 , a connecting bolt 5 and a spring hanging rod 6, the connecting bolt 5 passes through the screw hole of the cover plate 2, the arc-shaped slot 4-1 of the rotating disc 4 and the screw hole of the probe card 1 to connect the three intoFigure 3 The integrated structure shown has four connecting bolts 5 and two arc-shaped grooves 4-1 to ensure balance during movement. The arc-shaped grooves 4-1 of the rotating disk 4 are designed to facilitate the rotation of the rotating disk 4, such as... Figure 10 As shown, the arc length matches the rotation angle of the rotary disk 4; the upper surface of the cover plate 2 is provided with a connecting lug 2-1 connected to the robotic arm to achieve a fixed connection between the entire connecting joint and the robotic arm, as shown. Figure 6 The number of connecting ears 2-1 is two, and each connecting ear 2-1 is provided with a pin hole 2-2 for connecting to the robotic arm and facilitating the rotation of the connecting joint relative to the robotic arm. The lower surface of the cover plate 2 is provided with an arc-shaped mounting groove 2-3 for installing a return spring 3, such as... Figure 7 As shown, the spring rod 6 is fixed on the rotating disk 4. Figure 2 One end of the spring rod 6 is fixed to the arc-shaped mounting groove 2-3, and the other end is fixed to the corresponding mounting groove 4-3 of the rotating disk 4. The elastic force generated by the reset spring 3 keeps the rotating disk 4 in its original state, ensuring that the insertion blind hole 4-2 on the rotating disk 4 is misaligned with the insertion through hole 1-1 on the probe card 1. When an external force drives the rotating disk to overcome the elastic force of the reset spring 3, the insertion blind hole 4-2 aligns with the insertion through hole 1-1, and the four insertion ears 7 on the laser probe head pass through the insertion through hole 1-1 and enter the insertion blind hole 4-2. A sliding platform is connected to one side of the insertion blind hole 4-2 of the rotating disk 4 to facilitate the insertion ears. 7. Rotate into the sliding platform. At the end of the sliding platform, the corresponding probe card 1 has a countersunk hole 1-2 for the insertion ear 7 to fall into. Release the rotating disk 4. The reset spring 3 drives the rotating disk to reset. The unprocessed part of the rotating disk 4 presses against the countersunk hole 1-2, so that the insertion ear 7 is positioned in the probe card 1 and cannot move. Rotate the rotating disk 4 again to push the laser probe head upward, forcing the insertion ear 7 to leave the countersunk hole and enter the sliding platform. Rotate the laser probe head to make the insertion ear 7 enter the insertion blind hole 4-2 and then remove it downward from the insertion through hole 1-1, thus completing the rapid separation of the laser probe head and the connector.

[0025] All parts not covered in this invention are the same as or can be implemented using existing technologies.
