A limiting part 6 is arranged between the handrail tube 3 and the handrail seat 1, and the limiting part 6 comprises two limiting rods 61 and two limiting grooves 62. Wherein, two spacing grooves 62 are axisymmetrical about the guide groove 13, and two spacing grooves 62 are arc-shaped, and the distance from each position of the spacing groove 62 to the rotating shaft 31 is consistent. The limiting rod 61 penetrates through the limiting groove 62 and is connected to the handrail tube 3 in a rotating mode, and the rotating direction of the handrail tube 3 can be limited, so that the handrail tube 3 can rotate into the notch 17.

Referring to fig. 4, the two handrail tubes 3 are both provided with a groove 32, the groove 32 is arranged on one side away from the notch 17, and when the two handrail tubes 3 are arranged on the same straight line, the two folding rivets 4 abut against the groove 32, so that the support strength of the folding rivets 4 to the handrail tubes 3 is stronger.

The implementation principle of the embodiment is as follows: initially, the two folding rivets 4 are positioned in the locking holes 15, and the folding rivets 4 abut against the grooves 32 on the handrail tubes 3, so that the two handrail tubes 3 are positioned on the same straight line; when the handrail needs to be folded, the key 2 is pressed, the folding rivets 4 are separated from the locking holes 15 and are closed under the action of the rails 22 and the strip-shaped holes 14, the two folding rivets 4 are separated from the handrail tubes 3, the two handrail tubes 3 are rotated along the limiting grooves 62 until the two handrail tubes 3 fall into the notches 17, and the two handrail tubes 3 are folded. After the key 2 is released, the reset spring 5 drives the adjusting rod 16 to move towards the end close to the guide rod 21 along the adjusting groove 23, and drives the key 2 to reset, namely, the two folding rivets 4 can be driven to move towards the end far away from the other side until the folding rivets 4 move into the locking holes 15, and the folding rivets 4 can support the handrail tube 3 tightly again, so that the handrail tube 3 is prevented from rotating randomly.

Example two:

referring to fig. 5, the difference from the first embodiment is that: the limiting member 6 is a flexible strip 63, a mounting hole 64 is formed in one side, facing the notch 17, of the handrail tube 3, one end of the flexible strip 63 is inserted into the mounting hole 64, a limiting portion 65 is arranged at one end inserted into the mounting hole 64, and the other end of the flexible strip is connected to the inner side wall of the connecting portion 12 of the handrail seat 1.

When the two handrail tubes 3 are in the unfolding state, the flexible strips 63 are tensioned, the limiting parts 65 are abutted against the inner side walls of the handrail tubes 3 to limit the rotating angle of the handrail tubes 3, and the handrail tubes 3 can be driven to rotate towards the direction of the notch 17 when being folded. The flexible strip 63 can be connected to the armrest seat 1 by fixing means such as bonding. The flexible strip 63 can be a rope, a cloth strip, a nylon belt, a plastic belt and the like, can be bent and folded, and is a strong-toughness part. Compared with the arrangement of the limiting rod 61 and the limiting groove 62 in the first embodiment, the flexible strip 63 in the first embodiment is low in cost, the punching process of the mounting hole 64 is simpler than that of the arc-shaped limiting groove 62, the production efficiency can be improved, and the cost is saved.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
