The supporting device includes a first rod body provided with a first collar and a second rod body provided with a second collar, the first collar has a first chamber and a first positioning part arranged in the first chamber, the second The second collar and the first collar are interfitted with each other and have a second chamber communicating with the first chamber and a second positioning part arranged in the second chamber. The first and second chambers are provided with elastic members and clips. The locking piece is pushed by the elastic piece and is located between the first and second chambers, and the locking piece is provided with a restricting part that interferes with the first and second positioning parts, so as to limit the relative movement of the first rod body to the second The rod body is pivoted, and an actuating unit is provided on one side of the second collar, which has a driving part that extends into the second chamber and abuts against the clamping part. The first chamber allows the second positioning portion to break away from the restraint of the restricting portion, so that the first rod can pivot relative to the second rod.

Description

technical field [0001] The invention relates to a support device, in particular to a support device applied to a foldable stroller, a foldable stroller frame and an operation method for folding the stroller frame.
