sleeve 7 is rotated so that the via holes 70 of the protectingsleeve 7 are aligned to the rotary blocks in thewindow 21 of the lockingseat 2. Then the rotary blocks 41, 42, 43, 44 and 45 are rotated sequentially so that the lock numbers of the lock are aligned to the positioning scales 28 of the lockingseat 2. As a result, theeccentric holes rings annular grooves 83 on the locking means 80. Thetelescopic rod 8 is pulled outwards so as to form a first unlocking stage. - When the
telescopic rod 8 is pulled until the bucklingpin 87 on therod body 85 is stopped by the bucklingend 92 of thestud lock rod 9, thetelescopic rod 8 is rotates so that thenumber scale 88 of thetelescopic rod 8 is aligned to thepositioning scale 55 of the retainingseat 5. Then, the bucklingpin 87 on therod body 85 of thetelescopic rod 8 also rotates to be aligned to thenotch 94 of the bucklingend 92 of the stud lock rod 9 (referring to Figs. 9 and 10). Then the bucklingpin 87 will not be stopped by the bucklingend 92. Then thetelescopic rod 8 can be pulled outwards (referring to Figs. 11). Thelinkage 86 on thetelescopic rod 8 is positioned on theinsertion groove 54 of the retainingseat 5. Thus, therod body 85 of thetelescopic rod 8 will not pass through theinsertion groove 93 of the bucklingend 92 of thestud lock rod 9. Thus the second unlocking stage is formed. - When the
stud lock rod 9 is unlocked, thestud lock rod 9 is buckled to the rim of a wheel of a bicycle, and the bucklingend 92 of thestud lock rod 9 inserts into theinsertion hole 54 of the retainingseat 5, thereby, thenotch 94 of thestud lock rod 9 is coupled to thelinkage 85 of thetelescopic rod 8 until theinsertion groove 93 is aligned to therod body 85 of thetelescopic rod 8. Then thetelescopic rod 8 is pushed toward the lockingseat 2 and therod body 85 of thetelescopic rod 8 passes through theinsertion groove 93 of thestud lock rod 9. The bucklingend 92 of thestud lock rod 9 is fixed in the retainingseat 5 by thetelescopic rod 8. The rotation of thetelescopic rod 8 will cause that the set number is aligned to thepositioning scale 55 of the retainingseat 5, while the bucklingpin 87 of thetelescopic rod 8 is aligned to the slidinggroove 61 of thestopper 6. Then thetelescopic rod 8 can be pushed inwards. Next, the rotary blocks of the combination lock 4 in the lockingseat 2 can be rotated to other position so that theeccentric holes blocks annular grooves 83 of the locking means 80 of thetelescopic rod 8. Thereby, the operation of locking is completed. - In the present invention, the combination lock 4 is locked and then by the stopping effect of the buckling
pin 87 of thetelescopic rod 8, then the two locking effect is presented in the present invention. If a thief is desired to unlock the lock of the present invention, he (or she) must unlock the five numbers of the combination lock 4 and the number set in the bucklingpin 87 of thetelescopic rod 8 must be resolved. It is very difficult to unlock the lock of the present invention. A preferred burglar-proof effect is achieved. - When it is desired to unlock the lock, the user only needs to rotate the rotary blocks of the combination lock 4 to the unlock numbers of the lock. The
eccentric holes telescopic rod 8 can be pulled outwards to a first unlocking length, and thentelescopic rod 8 rotates so that the scales of the set unlock number of the bucklingpin 87 is aligned to thepositioning scale 55 of the retainingseat 5. Then the bucklingpin 87 on therod body 85 of thetelescopic rod 8 also rotates to be in thenotch 94 of the bucklingend 92 of thestud lock rod 9, thereby, the bucklingpin 87 will not be stopped. Then thetelescopic rod 8 is pulled outwards through a second length (referring to Fig. 11). Thelinkage 86 of thetelescopic rod 8 is positioned in theinsertion groove 85 of thetelescopic rod 8, while thenotch 94 of thestud lock rod 9 will fall out of thelinkage 86 of thetelescopic rod 8. Hence, unlocking operation is completed and the operation is easily. - In the present invention,
eccentric holes rings telescopic rod 8 is eccentric. One side of thetelescopic rod 8 has a larger cut surface and another side thereof has asmaller cut surface 82. The eccentric design causes that the lock only has only correct number. Referring to Fig. 12, theeccentric holes telescopic rod 8 is stopped by the confiningrings telescopic rod 8 can not protrude out or reduce inwards. Thereby, the effect of burglar-proof is achieved. - Advantages of the present invention is that there are two locking stages so as to have a preferred burglar-proof is achieved. The locking and unlocking of the present invention are not performed by using any key. Thus the operation is convenient.
- The present invention is thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the present invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
