Set key;Ring tooth has a release link, and being rotated backward after key insertion lock core makes the release link of ring tooth act on described set
Set key.
It is additionally provided with to position the positioning device of the handle position between handle base and handle, handle base has with handle
The interconnection face that mutual face contacts and is slidably connected, the positioning device includes being set in the interconnection face
At least one of the positioning recess can be sticked by being correspondingly arranged on several positioning recess and another joint face on one joint face
Positioning convex point, the positioning recess is along handle rotating direction and the setting that mutually spaces out.
The positioning recess is set on handle, and the positioning convex point is can be along the circle of handle rotating axis axial stretching
Ball, handle base have an axial limit chamber axially in the same direction with handle rotating axis, and ball is arranged in limit chamber and energy by limitation
Part is stretched out outside limit chamber, and tower spring is provided in limit chamber and is stretched out outside limit chamber with supporting rounded portion to stick into corresponding positioning
In recess.
Positioning recess shares eight, and each recess that positions is equally spaced same circumference centered on by handle rotating axis
On.

Specific implementation mode
As shown in attached drawing 1 to attached drawing 6, a kind of door lock includes handle base 100 and is connected with handle base 100 and can be opposite
The handle 101 that handle base 100 rotates is provided with to limit between handle base 100 and handle 101 or allows handle 101 opposite
The arrangement of clutch that handle base 100 rotates, the arrangement of clutch include the mounting base 102 being fixedly mounted on handle 101 and fix
Locking bolt seat 103 in handle base 100, the mounting base 102 be provided with locking bolt 1 and to drive locking bolt 1 be inserted into or from
The driving device of unlocking bolt seat 103.
The locking bolt 1 can be axially along slidably arranged in the mounting base 102, have plug division 11 on locking bolt 1;
The driving device includes motor 21, and the output shaft of motor 21 is provided with worm screw 211, and the mounting base 102 is provided with slide bar 22,
Impeller 23 is provided on slide bar 22, impeller 23 is extended from one end of slide bar 22 to the worm screw 211 there are two promotions
Bar 231, two catch bars 231 are inserted into after being each passed through the adjacent between cog of worm screw 211 in the plug division 11 of locking bolt 1, plug division 11
For along the circumferential recessed circumferential slot of locking bolt 1.
The sliding block 24 that can be axially slided along slide bar 22 is arranged on the slide bar 22, be arranged on the slide bar 22 there are two
Balancing spring 25 and the both sides for being respectively arranged at the sliding block 24;The impeller 23 is made of elastic material, and impeller 23 wraps
The wound portion being wrapped on sliding block 24 is included, two catch bars 231 are extended from wound portion to the worm screw 211 respectively.
It is made of elastic material by the way that balancing spring 25 and the impeller 23 is arranged, therefore, even if in the feelings of 21 continuous work of motor
Under condition, motor 21 will not be caused to burn due to being blocked by impeller 23, or lead to the increase of power consumption.
The driving device further includes the lock core 31, ring tooth 32 and actuating member 33 being arranged on handle 101, the ring
The setting of tooth 32 is in the and then key turns on lock core 31 and when key is inserted into lock core 31, and as shown in Fig. 9, ring tooth 32 is provided with
Several ring teeth 321, actuating member 33 are installed in rotation on handle 101, and several and ring tooth 321 is provided on actuating member 33
The effect tooth 331 being meshed, effect tooth 331 and ring tooth engagement, actuating member 33 are additionally provided with one and act on institute with its rotation
State the service portion 332 that locking bolt 1 makes locking bolt 1 be inserted into or leave locking bolt seat 103.
As shown in attached drawing 7 and attached drawing 8, service portion 332 is arc body, and the rotation axis of the circle core shaft and actuating member 33 of arc is same
Axis, arc body include thicker section 41, compared with light filling bar 42 and the thicker section 41 of smooth connection and compared with the changeover portion 43 of light filling bar 42, actuating member 33
Rotation make thicker section 41 act on the locking bolt 1 to be inserted into locking bolt seat 103 to push away it, the rotation of actuating member 33 makes compared with light filling bar 42
When acting on the locking bolt 1, locking bolt 1 leaves locking bolt seat 103 under the action of the catch bar 231.
Ring tooth 32 is linked by a lock pin and the lock core 31, and being rotated forward after key insertion lock core 31 makes ring tooth 32
When, actuating member 33 acts on the locking bolt 1 to thicker section 41 compared with light filling bar 42 certainly and acts on the rotation of 1 direction of the locking bolt;It is described to hold
Hand 101 is provided with fingerprint and retouches module, master control borad 51 and power supply 52, and the motor 21 is connected electrically on master control borad 51, the master control
Plate 51 is provided with that the set key of 51 function of master control borad is arranged;There is ring tooth 32 release link 322, key to be inserted into lock core 31
Rotating backward afterwards makes the release link 322 of ring tooth 32 act on the set key.
It is additionally provided with to position the positioning device of 101 position of the handle, handle base between handle base 100 and handle 101
100 have the interconnection face that mutual face contacts and is slidably connected with handle 101, and the positioning device is including being set to institute
Be correspondingly arranged on several positioning recess 61 and another joint face on a joint face in the interconnection face of stating can stick into it is described
At least one positioning convex point of recess 61 is positioned, the positioning recess 61 is along 101 rotation direction of handle and mutually spaces out
Setting.
The positioning recess 61 is set on handle 101, and the positioning convex point is that can axially be stretched along 101 rotation axis of handle
There is an axial limit chamber axially in the same direction with 101 rotation axis of handle, ball to be existed by limitation setting for the ball of contracting, handle base 100
It in limit chamber and can partly stretch out outside limit chamber, tower spring is provided in limit chamber and is stretched out outside limit chamber with card with supporting rounded portion
Into in corresponding positioning recess 61.Positioning recess 61 shares eight, and each recess 61 that positions is equally spaced with 101 turns of handle
On same circumference centered on moving axis.Therefore, there is stronger pause feel when handle 101 rotates 45 degree and handle can be made
101 rest on corresponding position, increase the diversity of selection, suitable for a variety of occasions for needing 101 placement angle of handle.
