To open the cover, the lock of the present invention must be operated in accordance with the following two steps to complete the unlocking operation. 11 1293658 Referring to Figure 9, π, before the lock is unlocked, the lock core 313 of the lock block 31 of the latch unit 3 of the lock is in the locked position. In the locked position, the rear portion of the lock body 312 of the squat body and the 31 is completely hidden in the lock case 311 of the lock body module 31, and the limit piece 315 of the lock body module 31 is exactly The limiting members 411 of the fixing base 41 of the interlocking unit 4 are mutually engaged, so that the locking body 312 is pinched by the limiting piece 315 and the locking core 313 and cannot be pushed through. Therefore, in the first phase, the lock cylinder 313 must be switched from the lock position to the non-lock position. Then, the key is inserted into the key hole 371 of the lock cylinder 313. At this time, the lock cylinder 313 can be rotated to the non-locking position in the rotation direction as indicated by an arrow 61 in FIG. 9, during the rotation of the lock cylinder 313. The locking piece 314 and the limiting piece 315 are rotated, and the limiting piece 366 of the locking body 312 is slid by the locking end 3141 of the limiting groove 3140 of the locking piece 314 to the non-locking of the limiting groove 314 End 3142. When the non-locking position is β, the limiting piece 315 is away from the limiting piece 411, so that the locking body 312 is not restricted by the limiting piece 3 15 and the locking core 313, and can be limited to the locking case 3 The position of the hole 351 slides. Referring to FIGS. 10 and 12, in the second stage, the lock body 312 of the lock body module 31 of the latch unit 3 is slidable relative to the lock case 311 in a snap-like state and a non-snap state. unlock. In the latching state, the rear portion of the lock body 312 is completely hidden in the lock housing 311, and the latch 421 of the snap module 42 of the linkage unit 4 is inserted into the latch unit < And the two latching portions 4211 are fastened to the two latching blocks 52. In the direction indicated by the arrow 62 in FIG. 11 , during the process of pushing the end face of the lock body 12 1293658 body 3 12 to the non-card type, the lock body 312 drives the lock core 313 to slide, and the inside of the lock body 313 is slid. And the rack module 32 is slid at the same time, and the rack handle 322 and the (4) strip portion 322 of the second block 322 further drive the driven gear 422 of the buckle module 42 and the driven gear 432 of the transmission rod mold 1 and 43, When the lock bolt 421 and the transmission rod are rotated 431, the force is not on the α, and the second lock portion 4211 of the lock 421 is no longer buckled. The card slot of the card is 521, so that the cover can be separated. Referring to FIGS. 6 and 7 ′ for the convenience of operation, the elastic member 316 of the lock body module 31 of the unit (10) surrounds the small peripheral diameter portion 362 of the lock body 312 of the lock body module 31, and the two ends respectively abut the lock.
