The specific embodiment

Below in conjunction with a preferred embodiment and accompanying drawing the technical solution of the utility model is further described:

Consult Fig. 1-5, this case inventor provides a kind of stepless handrail, it comprises movable hand rail 7 and handrail fixed bar 12, the tail end of movable hand rail 7 offers axis hole, one side of axis hole is provided with a fixed head 2, and described handrail fixed bar 12 passes fixed head 2 and is set in the described axis hole, it is characterized in that, this handrail also comprises a handrail locking mechanism, and described handrail locking mechanism mainly comprises to be separated locking plate 1, separate lock dog 6 and hold spring 10; The described spring 10 of holding is arranged in the described axis hole and is set on the handrail fixed bar 12, and a side of holding spring 10 is connected with fixed head 2 conflicts, opposite side with separate locking plate 1 and be connected; Described separating on the inwall that lock dog 6 is arranged at axis hole, an end of separating lock dog 6 with hold the spring port and be connected, the other end of separating lock dog 6 is connected in fixed head 2 by a lock dog steady pin 5, separates and also is provided with a torsion spring 8 between lock dog 6 and the fixed head 2; Separate on the lock dog 6 and be provided with a return pin 16 near the position of holding spring 10, return pin 16 is connected with a jump ring 9 with the sidewall of separating lock dog 6.

As a kind of preferred version, a side relative with separating lock dog 6 is provided with one and holds spring fixed block 14 on the inwall of described axis hole, describedly holds spring fixed block 14 and holds spring 10 and conflict and be connected.

As a kind of preferred version, the described spring 10 of holding is connected on the handrail fixed bar 12 by a spring fixed column 3; Wherein, described spring fixed column 3 can be structure as a whole with handrail fixed bar 12.
