[0026] See also Figure 3 The connecting rod group 10 includes a card frame 1001 and a card slot 1004. The card frame 1001 can limit the magnetic blackboard 9. The card frame 1001 is slidably connected to the magnetic blackboard 9. Both ends of the front side of the card frame 1001 are threadedly connected with bolts 1002 through nuts. The bolts 1002 can fix the magnetic blackboard 9. The ends of the two card frames 1001 that are away from each other are fixedly connected with connecting arms 1003. The connecting arms 1003 can support the card frames 1001 to rotate, and the connecting arms 1003 are rotatably connected to the frame 7. The card slot 1004 is connected to the outside of the frame 7.

[0027] See also Figure 4 , Figure 5 and Figure 6The twisting wheel group 11 includes a twisting wheel 1101, and one end of the twisting wheel 1101 close to the connecting rod group 10 is made of rubber material, so that the position of the connecting rod group 10 can be fixed in cooperation with the frame of the frame 7. The end of the twisting wheel 1101 close to the connecting rod group 10 is fixedly connected with a threaded rod 1107, and the threaded rod 1107 is threadedly connected to the connecting arm 1003, and the threaded rod 1107 can be threadedly connected to the inside of the clamping rod 1103, and then the twisting wheel 1101 is fixed. The inside of the twisting wheel 1101 is slidably connected with a slide plate 1102, and the slide plate 1102 can slide inside the twisting wheel 1101, and the outside of the slide plate 1102 is evenly connected with springs 1106, and the springs 1106 can drive the slide plate 1102 to move. The spring 1106 is connected to the inside of the twisting wheel 1101, and the end of the slide plate 1102 away from the spring 1106 is evenly connected with the clamping rod 1103, and the clamping rod 1103 can prevent the twisting wheel 1101 from reversing. The outside of the clamping rod 1103 is provided with an inclined surface 1104, and the inclined surface 1104 is designed to be low at the back and high at the front. The inclined surface 1104 can rotate clockwise inside the slot 1004, but cannot rotate counterclockwise. The end of the slide plate 1102 away from the clamping rod 1103 is fixedly connected with a short arm 1105, and the staff can pull the short arm 1105 outward, and then drive the clamping rod 1103 to return from the inside of the slot 1004, so that the twisting wheel 1101 can rotate normally counterclockwise.

[0028] The present invention facilitates the movement of the bottom frame 1 by means of the universal wheels 5 and the directional wheels 6, and at the same time, facilitates the position of the bottom frame 1 to increase the stability of the bottom frame 1 when in use by means of the directional wheels 6. The cooperation of the mesh plate 4 and the mesh frame 3 facilitates the stacking of goods, and the magazine box 8 is provided to facilitate the staff to place brochures. The added magnetic blackboard 9 facilitates the promotion of goods, and the magnetic blackboard 9 can also fix the promotional materials by its magnetic attraction characteristics. The connecting rod group 10 is provided to facilitate the rotation of the magnetic blackboard 9, so that the magnetic blackboard 9 can achieve the promotional display effect at different angles on the front and back sides, and at the same time, by screwing the threaded rod 1107 into the connecting arm 1003, the magnetic blackboard 9 can be rotated to achieve the promotional display effect at different angles on the front and back sides. The internally coordinated twisting wheel 1101 rubs against the frame 7 to fix the angle of the connecting arm 1003. At the same time, when the twisting wheel 1101 rotates, the clamping rod 1103 can be inserted into the inside of the clamping slot 1004. The clamping rod 1103 can only rotate clockwise due to the external inclined surface 1104 of the twisting wheel 1101. When rotating counterclockwise, the clamping rod 1103 will be restricted by the clamping slot 1004, and then the twisting wheel 1101 will be limited to prevent the twisting wheel 1101 from being hit by external force, and then the limit of the connecting rod group 10 will be released, so that the magnetic blackboard 9 can rotate, reducing the publicity effect, and at the same time, it can also prevent objects fixed outside the magnetic blackboard 9 from falling.
