Description

TECHNICAL FIELD The present invention relates to the technical field of strollers, and specifically to a foldable stroller. BACKGROUND A device for receiving a child such as a carrycoat is usually suitable for babies from birth to about 15 months old. For a stroller with a device such as a carrycoat, the device is usually positioned on the two support rods of the frame of the stroller. In order to ensure the stability of the device, the two support rods must be spaced at a certain distance. Therefore, the two support rods are mounted on different components of the frame, causing that the distance between the two support rods changes with folding of the frame when the frame is folded, which makes it difficult to connect the device to the frame. When the stroller needs to be folded, the device is usually removed from the frame first, and then the frame is folded, which brings inconvenience to the folding. SUMMARY In view of the above-mentioned technical problem of the prior art, when a stroller with a device for receiving a child is folded, the device needs to be removed from the frame first, and then the frame is folded, which is troublesome in operation. The present invention provides the following technical solution to solve the technical problem: i.e. a foldable stroller, including a foldable frame and a foldable device for receiving a child, where the frame includes a first support rod and a second support rod, the distance between the first and second support rods being able to vary in the process of folding or unfolding the frame; and the device can be connected to both the first support rod and the second support rod, the device being provided with at least a first connecting assembly connected to the first support rod and at least a second connecting assembly connected to the second support rod, and when the frame is folded or unfolded, the second connecting assembly can move with the second support rod, so that said device remains connected to the first support rod through the first connecting assembly and connected to the second support rod through the second connecting assembly regardless of any changes in the distance between the first support rod and the second support rod. According to a particular aspect of the invention, the distance between said at least one first connecting assembly and said at least one second connecting assembly is aligned to the distance between the first support rod and the second support rod when the frame is folded or unfolded. According to a particular aspect of the invention, the first and second support rods, in the unfolded state of the frame, are in a substantially horizontal plane and support the device for receiving a child ; and wherein during the process of the frame being folded, the plane defined by the first and second support rods changes gradually from a substantially horizontal level to a non-horizontal level and thus turns the device into a non-used position; during the process of the frame being unfolded, the plane defined by the first and second support rods changes gradually from a non-horizontal level to a substantially horizontal level and thus turns the device into the position for receiving a child. According to a particular aspect of the invention, the second connecting assembly includes a guide rail and a sliding base, the guide rail being disposed on the bottom portion of the device, the sliding base being slidably connected to the guide rail, and the sliding base being connected to the second support rod. According to a particular aspect of the invention, an elastic member for driving the sliding base to reset is disposed at the bottom portion of the device. According to a particular aspect of the invention, the first connecting assembly is detachably connected to the first support rod, and the second connecting assembly is detachably connected to the second support rod. According to a particular aspect of the invention, the first connecting assembly includes a first connecting base, a first clamping hook, and a first torsion spring, the first connecting base being provided with a first concave groove for positioning the first support rod, a middle portion of the first clamping hook being pivoted to the first connecting base, and the first torsion spring being disposed on the first connecting base to drive the first clamping hook to lock the first support rod into the first concave groove; and the sliding base being provided with a second concave groove for positioning the second support rod, a second clamping hook and a second torsion spring being disposed on the sliding base, a middle portion of the second clamping hook being pivoted to the sliding base, the second torsion spring being disposed on the sliding base to drive the second clamping hook to lock the second support rod into the second concave groove, and a first unlocking mechanism simultaneously driving the first clamping hook and the second clamping hook to unlock being disposed
