212 end of pipe limits the rotary sleeve 250 and rotates.
Preferably, the height of salient point 254 described in every group is unequal, the quantity of the salient point 254 is the mandril 230 number
Therefore the integral multiple of amount can change mounting height of every group of 230 one end of mandril relative to 210 end face of terminal pad, can be realized
The replacement of key bit increases key bit number of structures, improves safety in utilization, 230 both ends of mandril are ball head structure, are subtracted
Resistance when few rotary sleeve 250 rotates, avoids mandril 230 from being stuck in the gap between adjacent salient point 254.
Specifically used process, 1. are adjusted, and are first oppositely arranged 110 end face of fixed disk and 210 end face of terminal pad, and make
Every group of mandril 230 and pin 120 before every group be luxuriant to be correspondingly arranged and end is in contact, and then, loosening round nut 190 can rotate
With mobile lock collar 170 in the position of mandrel 142, pin 150 consolidates lock collar 170 after being placed in open slot 175 after adjusting every group
Fixed, loosening lock-screw 260 and so that rotary sleeve 250 is rotated any one by coil 251 makes salient point 254 and 230 one end of mandril
The position of contact, since the height of every group of salient point 254 is unequal, so as to change, every group of 230 other end of mandril is opposite to be connected
The height of 210 end face of disk, pin 150 moves axially in open slot 175 after being made by the linkage of mandril 230 and preceding pin 120, most
Afterwards, every group of adjusting ring 130 is screwed come relative position of the pin 150 in open slot 175 after adjusting, and pin 150 is equipped with ring after making every group
Shape slot structure corresponds to the snap-gauge 174 in every group of annular groove 173, therefore, the ring channel structures of pin 150 after snap-gauge 174 can be made to be placed in
It is interior, realize the rotation of lock collar 170 and switch 180, and then after making pin 150 relative position lockset position of coupler；And then it can pass through
Change mandril 230 to be in contact from different salient points 254 and change lockset position of coupler by screwing adjusting ring 130, therefore, can adjust
The cooperation position of lock and key, and then the functional reliability and safety of lock and key are improved, avoid key from being carved again.
2. it uses, it is first that 110 end face of fixed disk is opposite with 210 end face of terminal pad by the above-mentioned lockset position of coupler set
Setting, and relative position is determined, then each mandril 230 is contacted with the correspondence of each salient point 254 that last time sets, so as to
It is aligned snap-gauge 174 and the ring channel structures of rear pin 150, the rotation of lock collar 170 He switch 180 can be made, pin 150 enters after making
In annular groove 173, realizes and unlock；Pin 150 is placed in open slot 175 after opposite direction screws switch 180 and makes when locking, by key assembly
200 are detached from lock assembly 100, and snap-gauge 174 and the ring channel structures of rear pin 150 is made to be staggered, and make lock collar 170 and switch 180 can not
Locking is realized in rotation, can play the role of security protection by upper shield 270, therefore, has convenient to use and safety excellent
Point.
Taking the above-mentioned ideal embodiment according to the present invention as inspiration, through the above description, relevant staff is complete
Various changes and amendments can be carried out without departing from the scope of the technological thought of the present invention' entirely.The technology of this invention
Property range is not limited to the contents of the specification, it is necessary to which the technical scope thereof is determined according to the scope of the claim.
