When the shopping trolley is used, as shown in fig. 1-3, when a child is carried for shopping, the backrest 303 is taken out and then the child is placed in the fence 308, the two feet are spread to extend out of the fence 308 at the front side, and the backrest 303 is correspondingly sleeved on the fence 308 according to the body shape of the child; if the baby is carried for shopping, the backrest 303 is taken out and sleeved on the rail 308 at the front side, and then the baby is placed in the rail 308; the design of the guardrail of the rocking chair 3 can adjust the position of the backrest 303 according to the body shape of the child, and the problem that the common shopping cart seat is suitable for only young children and infants and children with larger body shapes cannot be used is solved.

Step two, as shown in fig. 4-7, when the rocking chair 3 is started, the handle 223 is pulled backwards, the handle 223 drives the push rod 203 to rotate backwards around the second fixing shaft 221, so as to pull the torque spring 201, when the push rod 203 is located in the strip-shaped groove 224, the push rod 203 is pushed leftwards and rightwards, the push rod 203 drives the sliding barrel 215 to slide along the first fixing shaft 213, and meanwhile, the guide platform 216 slides along the sliding groove 214, so that the sliding barrel 215 moves horizontally and does not rotate; when the push rod 203 corresponds to the transmission groove 225, the gear shaping 217 and the brake gear 210 are in a suspended state, the auxiliary gear 219 is meshed with the driven gear 205, then the handle 223 is released, the push rod 203 rotates forwards under the action of the torque spring 201 and is clamped in the transmission groove 225, the starting state of the control box 2 is adjusted, then the shopping cart is pushed, the shopping cart drives the rear wheel 102 to rotate in the forward moving process, the main shaft 101 drives the driving belt wheel 103 to rotate, and therefore the driven belt wheel 106 is driven to rotate through a belt; when the driven pulley 106 rotates, the input shaft 211 and the driving gear 212 are driven to rotate, in this state, the driven gear 205 and the driving gear 212 are in meshing transmission through the auxiliary gear 219, so that the output shaft 204 and the first rotary disc 108 are driven to rotate, the first tension shaft 109 and the second tension shaft 306 are connected through rotating shafts at two ends of the linkage rod 301, so that the first rotary disc 108 rotates to drive the second rotary disc 305 to rotate through the linkage rod 301, so that the first linkage rod 304 is driven to rotate, and the first tension shaft 109 and the transmission shaft 107 are not concentric; the second tension shaft 306 is not concentric with the second turntable 305; the first link 304 is shorter in length than the second link 307; the first connecting rod 304 can be driven to swing left and right in the rotating process of the first connecting rod 304, and finally the swinging action of the rocking chair 3 is realized; the design of rocking chair 3 can realize driving the function that the seat rocked at shopping cart walking in-process, has solved that children's seat generally is fixed state, and more lively children sit relatively restraint on fixed seat and produce the problem of boring the taste, and this process does not have additional motor to provide power, and is energy-concerving and environment-protective.

Step three, as shown in fig. 4-7, the rocking chair 3 is fixed, the handle 223 is pulled backwards and then the push rod 203 is pushed leftwards and rightwards in the same way, when the push rod 203 corresponds to the fixing groove 226, the gear shaper 217 and the driven gear 205 are clamped with each other at the moment, the auxiliary gear 219 and the brake gear 210 are in a suspended state, and the auxiliary gear 219 is always in an idle state in the process of pushing the shopping cart; since the guide table 216 slides along the slide groove 214, the slide cylinder 215 can only move horizontally but cannot rotate, so that the gear shaper 217 blocks the driven gear 205, the output shaft 204 is in a fixed state, and the rocking chair 3 stops working; the rocking chair 3 is in a stationary state during pushing of the shopping cart.

Step four, as shown in fig. 1-7, in the braking state, when the shopping cart only needs to be braked, the push rod 203 is pulled backwards in the same way, then the push rod 203 is pushed leftwards and rightwards, when the push rod 203 corresponds to the braking groove 227, the driven gear 205 and the gear shaping 217 are in a suspended state, the auxiliary gear 219 and the braking gear 210 are meshed with each other, because the braking gear 210 and the sleeve are fixedly arranged, the sleeve is fixedly connected with the shell 202 through a screw, the braking gear 210 blocks the auxiliary gear 219, the driving gear 212 is in a fixed state, and therefore the two rear wheels are in a braking state; similarly, when the rocking chair is fixed by braking, the push rod 203 is adjusted into the brake fixing groove 228226, at the moment, the gear shaping 217 is meshed with the driven gear 205, the auxiliary gear 219 is meshed with the brake gear 210, and the brake gear 210 and the gear shaping 217 are in a fixed state, so that the rocking chair is in a fixed state, and the rear wheel is in a brake state; the thickness of the driving gear 212 is larger than the distance between the brake gear 210 and the driven gear 205, the distance between the gear shaping 217 and the auxiliary gear 219 is larger than the thickness of the driven gear 205, and the phenomenon that the gear operation of the control box does not interfere under four control states can be realized; the design of the control box can realize four functions of braking, starting the rocking chair, fixing the rocking chair and braking the fixing rocking chair.

It is to be understood that the above-described embodiments of the present invention are merely illustrative of or explaining the principles of the invention and are not to be construed as limiting the invention. Therefore, any modification, equivalent replacement, improvement and the like made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention.
