Distance of the narrow edge to 137 center line of rotating cylinder.
The operation principle of the present embodiment：Upon insertion, first, it keeps holding helping pull rod 146 so that card column 141 is far from slotting
Enter in hole and be inserted into, card column 141 can be kept to be inserted into the state for being inserted into hole under the elastic force of third spring 144, avoid and do not having
Have to pull to hold to help pin 22 can be inserted into when pull rod 146 and insert in the hole, avoids the generation of maloperation phenomenon；Then,
The pin 22 of controller 2 is inserted into and is inserted in the hole so that pin 22 starts to compress stripper plate 131 so that mobile bar 133 is to appearance
Intracavitary of receiving is flexible, and the first driven rod drives the second driven rod to the movement of accommodating chamber direction (when the first driven rod is located at installation
When the length long enough of intracavitary (state for being not inserted into pin 22), under the elastic force of wind spring 138, the second driven rod and first drives
Angle is acute angle between bar, that is to say that the second driven rod is larger to the distance between accommodating chamber with 137 junction of rotating cylinder, therefore
When the first driven rod enables to the second driven rod that rotating cylinder 137 is driven to rotate when length reduces in installation cavity) so that second
Driven rod is pulled on the position parallel with the first driven rod, and then rotating cylinder 137 and eccentric wheel 130 is driven to rotate so that
130 broad edge squeezing roller 121 of eccentric wheel forces the 4th spring 128 to be compressed so that and the length of the first spring 127 shortens, this
When have the tendency that strongly being pushed into conducting ring 126 and insert in the hole under the effect of the first spring 127, due to helping pull rod 146 to pass through
The effect of card column 141 and third mounting blocks 142 so that conducting ring 126, which is appointed, is so in original position, but the warp-wise of motion bar 124
Stretched into conducting ring 126, avoid drawing conducting ring 126 and pin 22 interaction when being inserted into and wear so that conducting ring 126 with draw
The phenomenon that foot 22 is not in poor contact, while after being inserted into pin 22, conducting ring 126, which just has to stretch to, to insert in the hole
Trend ensures just to connect electricity after pin 22 is inserted into.When extracting pin 22, and pulls help pull rod 146 so that card column 141 is released first
It puts in pin 22 and guide ring retraction to pilot hole, then extracts pin 22, when extracting pin 22, the first driven rod is to peace
Interior elongation of behaveing affectedly drives the second driven rod and rotating cylinder 137 to rotate so that the narrow side of eccentric wheel 130 under 138 elastic force of wind spring
Edge and idler wheel 121 are tangent, under the elastic force of the 4th spring 128 and the first spring 127 so that motion bar 124 is to away from guide ring
Direction move, if also need continue to 130 direction of eccentric wheel move, pulling claw 123 pull the second mounting blocks 125 drive conducting ring
126 move together, solve the problems, such as that motion bar 124 is moved to eccentric wheel 130 and conducting ring 126 cannot be moved to eccentric wheel 130.
Finally illustrate, above example is merely intended for describing the technical solutions of the present application, but not for limiting the present application, although ginseng
The utility model is described in detail according to preferred embodiment, it will be understood by those of ordinary skill in the art that, it can be to this
The technical solution of utility model is modified or replaced equivalently, without departing from the objective and model of technical solutions of the utility model
It encloses, should all cover in the right of the utility model.
