The working principle is as follows: in the device, a bottom spring 8 and an inner spring 12 in fig. 2 are both in an unstressed natural state, a spring at the bottom end of a trigger magnet plate 16 in fig. 3 is in a compressed state, a track 4 is arranged at an entrance of a supermarket, when a worker pushes a long-row shopping cart body 1 to advance to be close to the track 4, the bottom wheel 3 at the bottom end of the first shopping cart body 1 is adjusted to slide into the track 4, the long-row shopping cart body 1 is continuously pushed to advance, the bottom wheels 3 at the bottom end of the subsequent shopping cart body 1 can also slide into the track 4 under the guidance of a front cart, and the long-row shopping cart body 1 can integrally and neatly advance;

the shopping cart body 1 is pushed to move forward continuously, the shopping cart body 1 is pushed to the state shown in figures 1 and 2, the first shopping cart body 1 is close to the fixed-point parking position, the shopping cart body 1 is pushed continuously, the bottom wheels 3 roll leftwards in figure 2, the front bottom wheels and the rear bottom wheels 3 simultaneously press the first trigger plate 6 and the second trigger plate 7 to be completely slid into the foundation 5, the first trigger plate 6 and the second trigger plate 7 drive the side lugs 9 to synchronously slide downwards and compress the bottom springs 8 and the arc edges of the 2 side lugs 9, simultaneously press the pulleys arranged at the sides of the first horizontal plate 10 and the second horizontal plate 11, simultaneously push the first horizontal plate 10 and the second horizontal plate 11 towards the trigger magnet plate 16 and compress the inner springs 12, so that the first horizontal plate 10 in figure 4 slides rightwards with the connecting plate 13 connected with the first horizontal plate 10, the second horizontal plate 11 in figure 5 slides leftwards with the connecting plate 13 connected with the second horizontal plate 13 connected with the first horizontal plate, specifically, 2 connecting plates 13 in fig. 3 all slide in the direction far away from the triggering

magnet plate

16, 2 connecting plates 13 drive the clamping blocks 14 at two sides to far away from the sliding-out side grooves 15, the triggering magnet plate 16 is no longer clamped by 2 clamping blocks 14, and slides upwards under the action of a spring with the bottom end in a compressed state, and at this time, the fixed magnet 2 at the bottom end of the shopping cart body 1 in fig. 1 just moves right above the triggering magnet plate 16, the magnets at the tops of the fixed magnet 2 and the triggering magnet plate 16 are neodymium magnets with strong magnetic force, and the opposite poles are arranged oppositely, so that the fixed magnet is adsorbed together, and the vertical plate-shaped structure made of 304 stainless steel at the bottom of the triggering magnet plate 16 still has most part remained in the foundation 5, so that the head cart of the shopping cart body 1 cannot continue to advance and is magnetically attracted to stop, the situation that the long shopping cart body 1 is too large in inertia and is not easy to stop colliding with walls and objects is avoided;

because the triggering magnet plate 16 in fig. 3 is clamped by the clamping blocks 14 and the side grooves 15 on both sides, when the first bottom wheel 3 in fig. 2 passes through the second triggering plate 7, although the second triggering plate 7 is pressed downwards, the connecting plate 13 and the clamping blocks 14 connected with the second horizontal plate 11 can move to be separated from the side grooves 15, because the first horizontal plate 10 is not triggered, the triggering magnet plate 16 cannot slide upwards, the problems of mistaken touch and early triggering are avoided, the stable operation of the device is ensured, and the magnetic attraction parking effect is achieved.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
