Below in conjunction with accompanying drawing the utility model is done into explanation.

As shown in Figure 1, a kind of direction of traffic machine git, it comprises steering shaft 1, steering-column tube 5, snap close and locking bolt, is provided with gear 11 as snap close on steering shaft 1, be provided with on the steering-column tube 5 with steering shaft 1 on gear 11 corresponding inner geares 12 as locking bolt.

By Fig. 1 to Fig. 6 as can be known, an embodiment of the present utility model is to be provided with an overcoat 6 on steering-column tube 5, lifting nut 8 is contained in the bottom of overcoat 6, radially have a groove at overcoat 6 housing bottoms, handle 7 is connected on the lifting nut 8 by this groove, lower edge at lifting nut 8 has two round recesseds (two round recessed radial direction of the present utility model become an angle of 90 degrees), the upper end is by the alligator swivel nut 16 that has been threaded, be provided with inner gear 12 in the top of alligator swivel nut 16 and the steering shaft 1 11 ingear corresponding positions that cog, appearance is provided with spline, spline housing 9 is housed between overcoat 6 and alligator swivel nut 16 and is fixed on the overcoat 6, the inside face of spline housing 9 is provided with spline, spline on the alligator swivel nut 16 stretches in the spline of spline housing 9, in the bottom of overcoat 6 and the adjacent of lifting nut 8 lock core 23 and axial with it bonded assembly half-round bar 17 are housed, lock core 23 is by straight pin 21, spring 22 is fixed on the overcoat 6, and axle sleeve box 10 is fixed on the top of overcoat 6.

When handle 7 plates during to locked position of coupler, lifting nut 8 drives alligator swivel nut 16 and does axially to rise along steering shaft 1 in spline housing 9, when rising to locked position of coupler, the inner gear 12 of alligator swivel nut 16 all meshes with the gear 11 on the steering shaft 1, at this moment driving half-round bar 17 rotations with key rotation lock core 23 is aligned in the round recessed of lifting nut 8 its disc one side, extract key out, make lock core 23, half-round bar 17, lifting nut 8, alligator swivel nut 16 all can not move, because the gear 11 on the steering shaft 1 is enclosed in the inner gear 12 of the strong swivel nut 16 of tooth, therefore steering shaft 1 can't rotate, and reaches the locking purpose.

When opening git, driving half-round bar 17 rotations with key rotation lock core 23 makes its plane one side aim at lifting nut 8 edges, rotating lifting nut 8 with handle 7 makes another round recessed on its edge aim at half-round bar 17, at this moment, lifting nut 8 has driven alligator swivel nut 16 and has axially descended along steering shaft 1, make the inner gear 12 of alligator swivel nut 16 throw off gear 11 on the steering shaft 1 fully, drive half-round bar 17 with key rotation lock core 23 then and rotate the round recessed that makes its disc one side aligning lifting nut 8 edges, extract key out, make lifting nut 8, alligator swivel nut 16 all can not move, direction machine safe opening.

For overhauling conveniently, be provided with stopple 18 at an end of half-round bar 17, for moving axially of control half-round bar 17, in the groove of the peace position of overcoat 6, also be provided with straight pin 20, spring 19.

The modes such as eccentric wheel that can also adopt the utility model realize that the axial motion of inner gear 12 controls the keying of git.
