Annulus 3-3 is radially also equipped with the second key pin 3-12 of the small step axle construction in the big one end in one end, which determines
Some stretches into keyhole to position pin 3-12 small ends, and the half slot that rotating ring 3-3 lower ends open up is opposite with the block of lock tongue 3-4
Should：A part for block is movably disposed in half slot；
Lock tongue 3-4 is slidably placed with below rotating ring 3-3, lock tongue 3-4 includes sliding block, and sliding block one end is provided with block, cunning
The block other end is provided with " L " shape latch hook, the fixation cotter way of strip is offered on sliding block, block side offers threaded hole, spiral shell
Screw 3-5 is fixed with pit, screw 3-5 one end is fixed with compression spring 3-6, and compression spring 3-6 one end withstands on handle lock housing 3-1 inner walls
Lock tongue 3-4 is arranged in lock tongue slot 1-4, and the latch hook of lock tongue 3-4 stretches out lock tongue slot 1-4 and part is stretched into handle groove 1-1,
The locking realized to handle 2 can be contacted with the handle locking groove 2-1 of handle 2；
Bottom plate 3-8 offers pin hole, which is provided with positioning pin 3-7, positioning pin 3-7 through lock tongue 3-4 fixation cotter way with
Rotating ring 3-3 connections, lock tongue 3-4 can be realized by the cooperation of the fixation cotter way of strip on positioning pin 3-7 and lock tongue 3-4
Horizontally slip guiding and it is spacing；
Bottom plate 3-8 is fixedly connected by flat head screw 3-9 with handle lock housing 3-1.
In above-mentioned, the clamping rings 3-2 and rotation of the first key pin 3-11 and the second key pin 3-12 installations
Also correspondence offers step pore structure to annulus 3-3, and the diameter of bore of the stepped hole is smaller than outer bore dia, its effect is only to allow
Corresponding positioning pin can only be put inward from outside, be dropped out to prevent positioning pin from keyhole, in the case where being acted on from external force, above-mentioned two
Stepped hole is on the same line and the straight line is parallel with its axis；
In main latch fitting 4 using in the case of contact opening ways, main lock lockhole is further opened with the corresponding pedestal 1 of main latch fitting 4
1-3, the main lock lockhole 1-3 are used to be inserted into main lock key；
Main latch fitting 4 is fixed on pedestal 1 in the following, and the main lock pin 4-1 in main latch fitting 4 and main lock by main lock fixed screw 4-5
Lockhole 1-3 is corresponding；
2 one end of handle offers handle locking groove 2-1, and 2 other end of handle, which is provided with, rotates pin hole 2-3, and rotation pin hole 2-3 leads to
Cross rotational pin 2-4 and handle fixing base 2-6 to be hinged, torsional spring 2-5 is also equipped with rotational pin 2-4, one end of torsional spring withstands on handle 2
Bottom surface, the other end of torsional spring are withstood on handle fixing base 2-6, and handle fixing base 2-6 is fixed on handle by handle fixed pin 2-7
In bottom tub 2-9, whole combination can realize that handle 2 is rotated upwardly and downwardly along handle groove 1-1 one end；In addition, in order to protect main lock
The lock core of part 4, the bottom surface corresponding with main lock pin 4-1 of handle 2 are further opened with dust-proof cushion film trap 2-2, are glued in dust-proof cushion film trap 2-2
Post dustproof gasket 2-8；Handle base groove 2-9 is to be fixed on 1 bottom surface of pedestal and cylinder corresponding with handle lock housing 3-1 sky
Core structure, the cylinder hollow-core construction radially offer the mounting hole for wearing handle fixed pin 2-7.
During unlocking, key 6 is inserted into handle lockhole 1-2 first, refer to Fig. 7 and Fig. 6, key 6 includes key body
60,60 side of key body is provided with cylindrical key bar 61, and key bar one end offers guide groove 63,63 one end of guide groove and rotation
Locating slot 62 connects, and rotational positioning groove 62 is opened up along key bar circumferencial direction；The key bar 61 of key 6 enters clamping rings 3-
When 2, it is necessary to the guide groove 63 of key 6 is directed at the small end that the first key pin 3-11 extend into endoporus, key bar 61 could be suitable
Profit enters clamping rings 3-2, and rotating ring 3-3, and at this time, the small end that the second key pin 3-12 stretches into keyhole is also clipped in
In guide groove 63；It can be rotated after key is fully-inserted, during rotation, guide groove 63 drives the second key pin 3-12 to stretch into
The small end rotation of keyhole, since the second key pin 3-12 is installed on rotating ring 3-3, also drives rotating ring
3-3 rotates, since rotating ring 3-3 lower ends offer half slot and the half slot is corresponding with the block of lock tongue 3-4,
Rotatory force when being rotated using half slot drives lock tongue 3-4 to move along a straight line, the lock of lock tongue 3-4 when lock tongue 3-4 is slided to the right
Hook departs from handle locking groove 2-1, and handle 2 is upspring under the action of torsional spring 2-5, completes the unlock work of handle 2；Complete handle 2
Unlock work after, key is become a full member so that guide groove 63 is corresponding with the first key pin 3-11, then extracts key, when guide groove 63
Not with the first key pin 3-11 to it is corresponding when the first key pin 3-11 stuck due to rotational positioning groove 62, can not
Key 6 is extracted, key can be unlocked main latch fitting 4 after extracting, because the present embodiment is preferentially using Application No.
Lock core disclosed in 200710165666.2 " a kind of electronic lock cylinder with arrangement of clutch and the electronic lock containing the electronic lock cylinder ", its
The corresponding patent document of unlocking manner is recorded in detail, is not detailed herein.
