The inductive head of the sensor (30) pass through sensor stand (29) fourth hole, and with the fourth hole (29) mistake
It is full of cooperation；
The sensor (30) can sense the position of the second contiguous block (19) of the self-locking link assembly (500).
7. telescopic pin according to claim 1, it is characterised in that self-locking link assembly (500) also includes jump ring；
The jump ring is mounted on the end of the 5th connecting portion (22), and forms the 3rd contiguous block (20), the pin rod
The restriction position of the first contiguous block (14) of component (100).
8. according to the telescopic pin described in any one of claim 1 to 7, it is characterised in that when compressed air entering by housing (1)
During gas port, the compressed air enters in the restriction position of the piston (12), and the piston (12) can be driven to move downward, this
When, the piston (12) drives the pin rod group by second bearing (28), the second contiguous block (19) and clutch shaft bearing (16)
Part (100) is moved upwards, and the pin rod (13) can be made to do extending action；
When air inlet of the compressed air by housing (1), the compressed air enters in the restriction position of the piston (12), energy
Enough drive the piston (12) upwards move, now, the piston (12) by second bearing (28), the second contiguous block (19) with
And clutch shaft bearing (16) drives the pin rod component (100) to move downward, and the pin rod (13) can be made to do retract action；
Wherein, the first translation direction of the piston (12) is converted into by turning for the second contiguous block (19) by second bearing (28)
Dynamic direction；
The rotation direction of second contiguous block (19) is converted into the second translation direction of the first contiguous block (14) by (25)；
Second translation direction of first contiguous block (14) is converted into the 3rd translation direction of pin rod (13) by (17), can
Pin rod (13) is set to do expanding-contracting action.
9. the control method of the telescopic pin described in a kind of claim 1 to 8, it is characterised in that using claim 1 to 9
The step of described telescopic pin realizes the action extended and retracted by compressed air.
