The specific embodiment

Shown in Fig. 1-6, a kind of handle tumbler of door lock includes lock panel 10, handle 20 and handle set 30, has rotating shaft through hole 11 on the lock panel 10, and handle 20 radially is fixedly connected through rotating shaft through hole 11 with handle set 30; Between lock panel 10 and handle set 30, also be provided with bidirectional spring 40; Bidirectional spring 40 is shaped to the internal diameter of helical form and bidirectional spring 40 greater than rotating shaft through hole 11 diameters; The bottom 41 of bidirectional spring 40 and the top 42 of bidirectional spring are bent into U-shaped bayonet socket 43 after spiraling and interlocking, and on the inwall of lock panel 10, are provided with positioning convex column 12, on handle set 30, have slide block 31; After the assembling; Bidirectional spring 40 is set in the outside of rotating shaft through hole 11, is stuck on the said positioning convex column 12 behind U-shaped bayonet socket 43 pretensions on the bidirectional spring 40, and said slide block 31 is connected in this U-shaped bayonet socket 43.

The inboard of said rotating shaft through hole 11 is extended with cartridge type centring ring 111, and bidirectional spring 40 is socketed on the cartridge type centring ring 111.

Also be provided with the spacing ring 32 with breach on the said handle set 30, after the assembling, said spacing ring 32 is on the same circumference with said positioning convex column 12.

The diameter of said spacing ring 32 is greater than the external diameter of bidirectional spring 40, and after the assembling, said spacing ring 32 is fastened on the outside of bidirectional spring 40.

Said handle set 30 is made up of the connecting axle 33 on handle set 30 tops and the junction plate 34 of handle set 30 bottoms, and said positioning convex column 31 is located on the junction plate 34, and after the assembling, the connecting axle 33 on the handle set 30 passes rotating shaft through hole 11 backs and radially is fixedly connected with handle 20.

Said connecting axle 33 is provided with the clamping key, is provided with the keyway of corresponding clamping key in the axis hole 21 of said handle 20.

Said handle set 30 is made up of the connecting axle 33 on handle set 30 tops and the junction plate 34 of handle set 30 bottoms, and said spacing ring 32 is located on the junction plate 34.

Said lock panel 10 is the lock panel on the electronic lock, and the bottom of handle set 30 has and is used for the connection keyhole 35 that is connected with electronic lock core.

During use; When the user clockwise rotated handle 20, handle 20 drove handle set 30 to turning clockwise, and the slide block 31 on the handle set 30 is stirred the top 42 of bidirectional spring 40 clockwise; Make bidirectional spring 40 to clockwise screw-pinch; In handle set 30 rotation processes, having a end on the spacing ring 32 of breach on the handle set 30, to turn to positioning convex column 12 limited, and handle set 30 is transferred to and realizes unlocking action in the electronic lock core through connecting keyhole 35; After answer was loosed one's grip, bidirectional spring 40 was replied deformation, and the slide block 31 that the top 42 of bidirectional spring 40 drives on the handle set 30 rotates counterclockwise, and is stuck in again on the positioning convex column 12 up to the top 42 of bidirectional spring 40, so just can realize accurately resetting;

In like manner; When the user rotated counterclockwise handle 20, handle 20 drove handle set 30 to being rotated counterclockwise, and the slide block 31 on the handle set 30 is stirred the bottom of bidirectional spring 40 clockwise; Make bidirectional spring 40 to counterclockwise screw-pinch; In handle set 30 rotation processes, having the other end on the spacing ring 32 of breach on the handle set 30, to turn to positioning convex column 12 limited, and handle set 30 is transferred to and realizes unlocking action in the electronic lock core through connecting keyhole 35; After answer was loosed one's grip, bidirectional spring 40 was replied deformation, and the slide block 31 that the bottom 41 of bidirectional spring 40 drives on the handle set 30 clockwise rotates, and is stuck in again on the positioning convex column 12 up to the bottom 41 of bidirectional spring 40, so just can realize accurately resetting;

By on can know that the present invention has is simple in structure, cost is low, the characteristics of easy accessibility, and the positioning function after realizing automatically reseting through bidirectional spring.
