[0002] At present, the existing shaft-to-shaft docking equipment is composed of a guide head and an in-place detection mechanism. The guide head is composed of a female head of a passive device and a male head of an active docking device, which plays a guiding and limiting role when the shafts are docked. When the docking is completed by the guide head, the in-place detection mechanism of a touch-type or inductive type is usually used to determine that the shafts are docked completely and send a signal to allow the next step to be performed. The in-place detection mechanism of the existing shaft docking equipment has defects in accuracy and durability;

[0003] Accuracy means that when the shaft docking is not completed or not completely docked, and the in-place detection mechanism is not 100% triggered, the in-place signal can still be sent; durability means that in the event of manual misoperation or errors in operating accuracy, the in-place detection mechanism is at a higher risk of damage. Therefore, an in-place detection mechanism and guide head assembly that can solve both accuracy and durability problems are needed. Utility Model Content
