By the cooperation of the first inclined surface 521 and the second inclined surface 511, the downward movement of the operating rod 51 is conveniently converted into the transverse movement of the pushing block 52, and the structure is simple and compact.

As shown in fig. 6 and 7, the linkage member 5 further includes a rotation block 53 disposed between the lower end of the support rod 14 and the upper end of the rear leg 11 and capable of rotating in a space enclosed by the support rod 14 and the rear leg 11, the rotation block 53 is provided with a plurality of inclined grooves 54 having inclined bottom surfaces along a circumferential direction, the lower end of the support rod 14 is provided with an inclined protrusion 55 capable of being engaged with the inclined groove 54 and pushing the rotation block 53 to move transversely when the rotation block 53 rotates, a pushing block 56 capable of being pushed by the rotation block 53 to move transversely when the rotation block 53 moves transversely is disposed between the rotation block 53 and the rear leg 11, the pushing block 56 is provided with a driving inclined surface 57, the upper end of the operation rod 51 is provided with a driven inclined surface 58 capable of being pushed by the driving inclined surface 57 to move the operation rod 51 downwardly when the pushing block 56 moves transversely, and a return spring 59 capable of pushing the pushing block 56 to return is further disposed between the rear leg 11 and the pushing block 56. When the stroller needs to be folded, the rotation block 53 is rotated by operating the stroller, and during the rotation process, the rotation block 53 moves transversely by the cooperation of the inclined groove 54 and the inclined protrusion 55, so as to push the pushing block 56 to move transversely, and the driving inclined plane 57 on the pushing block 56 pushes the driven inclined plane 58 on the operating rod 51, so that the operating rod 51 moves downwards, and the structure is simple and ingenious.

As shown in fig. 1, 6 and 7, a handle 10 is rotatably connected to the upper end of the support bar 14, and a pull rope 50 capable of pulling the rotation block 53 to rotate when the handle 10 is rotatably folded with respect to the support bar 14 is provided between the handle 10 and the rotation block 53. The length of the supporting rod 14 can be prolonged by the aid of the handle 10, so that the stroller can be pushed by an adult conveniently, and the handle 10 is rotatably connected with the supporting rod 14, so that the handle 10 can be folded on the supporting rod 14 when the stroller is folded, and the stroller is small in folded state and convenient to carry. More importantly, when the handle bar 10 is rotated and folded, the handle bar 10 can pull the rotating block 53 to rotate through the pulling rope 50, so that the pushing and pushing block 56 moves transversely, and the locking device 4 and the backrest locking mechanism 3 are synchronously unlocked through the operating rod 51, thereby realizing the folding of the stroller. Therefore, the backrest locking mechanism 3 and the locking device 4 can be unlocked only by rotating the hand push handle 10 forwards, and the operation is very convenient and fast.

As shown in fig. 6 and 7, an adjusting mechanism capable of adjusting the angle of the backrest 2 is further disposed between the moving block 33 and the outer seat 162, the adjusting mechanism includes a rotating block 61 disposed between the moving block 33 and the outer seat 162, an inclined protrusion 62 is disposed on the moving block 33, an inclined groove 63 capable of being engaged with the inclined protrusion 62 is disposed on the rotating block 61, when the rotating block 61 rotates, a groove wall of the inclined groove 63 pushes the moving block 33 to move laterally so that the engaging portion 35 is disengaged from the second engaging groove 32, a sliding sleeve 64 capable of sliding relative to the backrest 2 is disposed on the backrest 2, and a cable 65 capable of pulling the rotating block 61 to rotate is disposed between the sliding sleeve 64 and the rotating block 61. Therefore, the backrest 2 can also be adjusted in angle, so that the infant can ride more comfortably. The specific adjusting process is as follows: through the sliding sleeve 64, the sliding sleeve 64 pulls the rotating block 61 to rotate through the pull cable 65 in the sliding process, the rotating block 61 pushes the inclined protrusion 62 on the moving block 33 through the inclined groove 63 on the rotating block 61 in the rotating process, so that the moving block 33 moves transversely, the clamping portion 35 on the moving block 33 is separated from the second clamping groove 32 on the outer seat 162, the backrest 2 can be pulled to rotate the backrest 2 at the moment, when the sliding sleeve 64 is rotated to a proper position, the second spring 36 pushes the moving block 33 to reset, the clamping portion 35 is clamped with the other second clamping groove 32, and the adjustment of the angle of the backrest 2 is completed. Although the angle of the backrest 2 and the unfolding of the backrest 2 are locked by the clamping part 35 and the second clamping groove 32, the angle adjustment of the backrest 2 and the unlocking of the frame 1 are two independent operations, namely, the folding of the frame 1 and the backrest 2 can be realized by separating the clamping part 35 from the second clamping groove 32 when the frame 1 is folded, and the angle adjustment of the backrest 2 can be realized by separating the clamping part 35 from the second clamping groove 32 when the frame 1 is unfolded, so that the design is very ingenious.

As shown in fig. 6 and 7, the second engaging groove 32 is a ratchet groove, and the engaging portion 35 is a ratchet. Therefore, when the angle of the backrest 2 is adjusted forwards, the backrest 2 can be pulled forwards directly without pulling the sliding sleeve 64, so that the forward angle adjustment of the backrest 2 is more convenient and faster.
