[0039] Working principle: When it is necessary to install or replace the tool 5, the hydraulic rod 6 expands and contracts to drive the moving plate 7 connected to it to move, and then pushes the limit block 8 and the connecting plate 9 to move synchronously. The movement of the connecting plate 9 directly affects the movement of the fixed rod 10. Through this transmission relationship, the movement of the fixed rod 10 can release the tool 5 from the fixed plate 4, so that the tool 5 can be easily removed or installed. After the replacement or maintenance of the tool 5 is completed, the hydraulic rod 6 operates in reverse, and the fixed rod 10 returns to its initial position, and the tool 5 is firmly fixed on the fixed plate 4 again, thus simplifying the operation process and significantly improving the production efficiency of the equipment. When the robotic arm 3 operates, vibrations will be generated. If directly transmitted to the sensor 12, it will cause measurement errors. Through the ingenious design of the first spring 18, the second spring 19 and the rotating shaft 15, the buckle 16 has an elastic function, and through the close cooperation of the buckle 16 and the fixed block 17, the first connecting block 13 also has a certain elasticity, thereby reducing the influence of the vibration of the robotic arm 3 on the sensor 12, helping to obtain a more stable and reliable signal output, and avoiding instantaneous signal fluctuations caused by vibrations.
