From hole slot (77) lock body on outwards extract latch hook (76) with external force this moment; Because of shell fragment termination (69,74) are arced terminus, or hole slot (70,75) is the hole slot that hypotenuse is arranged, and just can make latch hook take out and shell fragment (67,81) is moved from lock body; Length of spring compressed; Latch hook just can take out from lock body, if groove on each pellet shot from a slingshot or V-type groove have one not with shell fragment (67,81) on hole slot on same straight line, and contact with the pellet shot from a slingshot external surface; Shell fragment can not move with regard to jammed, and latch hook just can not take out.Take this lock can be widely used on the various motor vehicles, on the various padlocks, tamper-proof and anti-technical opening ability is strong, and cost is low.During locking, earlier latch hook (76) is inserted again in the lock body hole slot (72,77), make the convenient insertion of latch hook because of the latch hook head has slope (87); Backward rotation key then; Key body and pellet shot from a slingshot disengage, spring make on each pellet shot from a slingshot groove or V-type groove again with shell fragment on hole slot or ∧ shape groove not on same straight line, key takes out from the key channel hole; Latch hook can not move, and has just accomplished the locking work of lock.Lock body links to each other with sleeve pipe (78) one ends and becomes integral body.Also can be to have only a cannelure (34) on the tapered end in Figure 12 and Figure 17; An open slot (49); With this lock supporting on the key have only a crooked connecting rod (18) and a key body (4) (see figure 3), adopt this kind lock head structure, lock core intensity is increased.Because of having only an open slot, the pellet shot from a slingshot that contacts with key body can be further from the open slot setting, and technical opening is just more impossible, in order to improve close capacity, can two groups of pellets shot from a slingshot among Figure 12, Figure 17 be lined up two row backs and contact with a key body.In like manner the external surface (125) of the external surface (125) of Figure 12, Figure 17 middle sleeve (41) and the sleeve pipe (78) on the lock core also include with Fig. 1 to Fig. 8 in shaped form key body (25) or arc key body (21) or crooked key body (25) or the equiform shaped form of non-curve key body (4) or arc or curved or non-curved sleeve pipe (41,78).

Asking for an interview Figure 29, Figure 24, Figure 25, Figure 27, is on a kind of tapered end that does not have a lock core at Figure 29, constitutes retaining device by removable plate washer (113) on the lock body and key channel hole (101) to the non-circular aperture (114) that key inserts mouthful (39); Figure 29, Figure 24 lock when being in blocking; The pellet shot from a slingshot (61,103) that is contacted with key by removable plate washer (113) isolation between key insertion mouthful (39) to key channel hole (101) etc. is hidden in the key channel hole; Inserting mouth from key can't see; To be these terminations of two slopes (99) contact with aperture (114) on the lock body (35) removable plate washer (113) one ends; The other end of removable plate washer (113) contacts with spring (92); Bigger round platform post (107) surface of external diameter on the shell fragment (102) of the round bar shaped in bigger aperture (108), the aperture on the ladder hole slot (109) on the removable plate washer and the lock body is on the same line and do not contact, or removable plate washer does not contact with shell fragment (102); By the arc-shaped slot on the circle bar shaped shell fragment external surface be diameter than small stair (106) and diameter greatly the external diameter on the deep-slotted chip breaker that connects into naturally of important actor (107) and the pellet shot from a slingshot (61) etc. contact than large part; Be on each pellet shot from a slingshot deep-slotted chip breaker (126) with circle bar shaped shell fragment (102) on the arc hole slot be not in same straight line (this technology is narrated) in the patent document that I apply in February, 2006, this pellet shot from a slingshot can not be moved.Under the blocking, the special-shaped termination (97) of shell fragment (102) be positioned on the lock body irregularly-shaped hole (96) on the rotating handle (93) on same straight line, but contact; Boss on the shell fragment (90) contacts with spring (89) on the lock body, makes round bar shaped shell fragment stressed to handle (93) direction.The bigger position of the pellet shot from a slingshot that resets in addition (103) top external diameter that contacts with arc hole slot on the shell fragment can not be moved shell fragment under blocking, the less slope of diameter (104) is arranged on the pellet shot from a slingshot that resets.The planar dimension of removable plate washer (113) is greater than the aperture size of key channel hole (101).Size less than the hole (55) on the key handgrip (9) among Figure 37; The setting of the boundary line (112) on removable plate washer upslope (99) and removable plate washer plane should be in key channel hole (101) and lean on the limit in key channel hole; Slope on the termination, slope (60) on the key body (4) among Figure 37 can be contacted with the slope on the removable plate washer; Removable plate washer is moved; The termination of adopting the band slope is that the key channel hole is lived by complete shield; Insert the non-circular hole slot (110) that is useful on placement key handgrip (9) (seeing Figure 37) between mouthful (39) to key channel hole (101) at key, like rectangle or square hole slot, the aperture of the hole slot (105) that move greater than ccontaining removable plate washer in the aperture of this hole slot (110).(see Figure 37 key) when unblanking, in conjunction with Figure 25, Figure 27 with matched key; By the sloping termination of key (60) earlier with removable plate washer (113) on slope (99) contact, make removable plate washer left direction move mobile distance; And sloping termination is not also fully from hole slot (114) when withdrawing from; Aperture small apertures (111) on the ladder hole slot (109) on the removable plate washer moves to and justifies on the bar shaped shell fragment, and the important actor that external diameter is bigger (107) contact is because of hole (111) diameter less than important actor (107); Shell fragment can not be moved; So just prevent that non-matching key from inserting or instrument inserts when unblanking, removable plate washer can not move shell fragment, and lock can not be opened.Key continues in lock, to insert, and being made by key body has termination, slope (99) to move on to the other end from an end of hole slot (114) on the removable plate washer, and repeats to get in the non-circular aperture (55) on the key handgrip along the key handgrip; Spring (92) gets in the hole slot (114) the slope end of removable plate washer (113) again and lives for whole shields in the key channel hole, and removable plate washer and shell fragment (102) are disengaged, at this moment; Curve on the key body (4) or groove or boss or tool tooth etc. move pellet shot from a slingshot (61) etc., and the deep-slotted chip breaker (126) on the pellet shot from a slingshot is on the same straight line with arc groove on the shell fragment, and the step on the key body moves the pellet shot from a slingshot that resets (103) simultaneously; External diameter on this pellet shot from a slingshot is disengaged than large part and shell fragment; And by the arc hole slot on the low ebb of the groove on this pellet shot from a slingshot or slope (104) and the shell fragment on same straight line and do not contact with shell fragment, like this, spring (89) just can make shell fragment (102) move; Make special-shaped termination (97) get into contact with it in the special-shaped hole slot (96) of handle (93); And the other end of shell fragment is exactly sword iron (33), and this sword iron still contacts with dead bolt, at this moment; Rotate handle; Circle bar shaped shell fragment rotates, and through sword iron dead bolt is moved, and completion is opened the door.Then key is taken out from the key channel hole; Because of slope (56) (seeing Figure 37) is arranged on the aperture on the key handgrip (55); Contact with slope (99) on removable plate washer (113) another side by slope, removable plate washer is moved to spring (92) direction, and removable plate washer is contacted with shell fragment; Shell fragment can not move; Moving of key body no longer contacts the slope step on the key body with the pellet shot from a slingshot that resets (103), it is moving that the spring that elastic force is stronger (91) makes the slope on the pellet shot from a slingshot that resets that shell fragment is made complex displacement;
