The specific embodiment
From accompanying drawing as seen, 1-2 reducing pellet shot from a slingshot (11) is equipped with in the inboard of tapered end (3) top tack pellet shot from a slingshot, shows T type (shown in Fig. 1 being 2); 1-2 major diameter pellet shot from a slingshot (8) is equipped with in the inboard of tapered end bottom tack pellet shot from a slingshot, and the diameter of major diameter pellet shot from a slingshot is greater than the lock core marble bore dia.The block (14) that can contact with the finger of unblanking (12) is arranged at tapered end (3) bottom, and block top and finger contact surface are inclined-plane (21).Be provided with stopper spring (16) between the bottom of the lower end of block (14) and tapered end (3).The axis of stopper spring is not with the lock body central lines but deflection finger one side.On lock core (6) perisporium, have 2-3 bar positioning groove.Unblanking has a finger spring (5) in the pin-shifting hole at finger (12) place.The front end of lock core (6) and lock core axis normal embed 2-4 hard metal material cylinder (17), can make lock core prevent that drilling from destroying.When this lock was installed, lock core (6) entered tapered end (3) fully, is in the installation position, and this lock can be lowered to the front fork lockhole from vertical tube of front fork is suitable for reading.Insert key then, lock core is moved to open position, lock core stretches in the front fork lockhole.At this moment, last reducing pellet shot from a slingshot falls because of deadweight in the lock body, exposes pellet shot from a slingshot hole retaining on the lock core aft end face, makes lock core can't get back to the installation position, but stays in the front fork lockhole, keeps tapered end (3) allocation really in vertical tube of front fork.When the need locking bicycle, insert key lock core is moved to locking bit, lock core enters front fork lockhole and vehicle frame lockhole simultaneously, and front fork is locked.This makes front fork to dismantle, and also can't sweep away tapered end by vertical tube of front fork.Lock internal stop this moment and rise fully, lock core (6) is blocked by block can not retraction.Even applied shock power, lock core is directly passed to vertical tube of front fork (26) by block with impulsive force along its axis direction, so also can't lean on the positive way of pounding lock core of dashing to break lock.Lock is installed under stem (23) position, on the vertical tube of front fork reducing position, does not influence the lifting levelling of handlebar, also need not do any adjustment to former body construction; The Front fork lock hole site is to open in the side of vertical tube of front fork (26) to well, and handlebar location steering angle is 10 degree-50 degree.Vertical tube of front fork position of opening scope cross-sectional strength is checked through methods of mechanics, does not influence front fork original design intensity.
