1. Improved compatibility of mounting flange: compatible with iso125, iso160-m12 and iso160-m10 flange standards;
2. The gas path control module integrates the design of tool gas supply. One path of gas can realize the simultaneous gas supply of gun disc change and tools, and simplify the layout of pipeline and air pipe;
3. Optimization of body locking mechanism: after upgrading, the locking force is increased by about 45%;
4. Cylinder detection: fixed inductive proximity switch, anti magnetic field interference, no adjustment required;
5. Share qt-650 locking mechanism and some functional modules.
