[0007] The locking hook is provided with a clamping hole on one side corresponding to the locking ring for clamping the locking ring, and is provided with a fixing plate on the other side for fixing the unlocking pull belt.

[0008] In the above scheme, the reset member is two respectively arranged on the left and right sides of the locking hook, and both are torsional springs.

[0009] In the above scheme, the locking ring is arranged in the cup holder mounting base frame, and a notch is arranged on the edge of the cup holder mounting base frame corresponding to the unlocking pull belt, so that a gap is left between the cup holder mounting base and the cup holder, and a through hole is formed for the unlocking pull belt to pass through.

[0010] In the above scheme, the cup holder mounting base is provided with an arc-shaped supporting plate corresponding to the unlocking pull belt for supporting the unlocking pull belt. The edges are reduced, the wear on the unlocking pull belt is reduced, and the unlocking pull belt is also easy to pull.

[0011] In summary, the beneficial effects of the utility model are: simple and compact structure, the locking hook is embedded in the cup holder assembly, the outside of the handrail is as clean as possible, and the appearance is improved. Meanwhile, the locking hook is installed on the cup holder mounting base, which can use the cup holder mounting base as an installation structure, without the need to separately provide a supporting member for the locking hook in the handrail, reducing the setting of parts in the handrail, and the structure is compact. The locking ring can be hooked together with the locking hook, so as to lock the handrail in the folded state. When unlocking, only the unlocking pull belt needs to be pulled, the structure is simple, and the operation is convenient. BRIEF DESCRIPTION OF DRAWINGS
