The fixing plate 5 is a rectangular plate whose side is fixedly connected to the inner side of the supporting tube 4. A limiting rod 6 is slidably provided in the supporting tube 4 on the front side of the fixing plate 5. The rear end of the limiting rod 6 is connected to the fixing plate 5 through a spring 7, and the front end extends out of the front end opening of the supporting tube 4. The front end surface of the limiting rod 6 is an inclined surface with the lower end inclined backward. A driving member for driving the front and rear limiting rods 6 to move relative to each other is provided on the supporting tube 4; in the two adjacent grid plates 1 on the left and right, the supporting tube 4 on the right grid plate 1 is located in the accommodating groove 2 on the left grid plate 1, and the limiting rods 6 at the front and rear of the supporting tube 4 are provided with an inclined end, both of which extend into the card groove 3 on the same side.

[0023] The size of the supporting tube 4 matches that of the containing groove 2 . The supporting tube and the containing groove on the same grid plate are opposite to each other on the left and right. The limiting rod 6 is a rectangular rod that slides sideways in contact with the inner wall of the supporting tube 4 .

[0024] When the front end of the limiting rod 6 at the front of the supporting tube 4 extends into the slot 3 on the same side, the spring 7 connected to the limiting rod 6 is in a natural state, the lower end of the front side surface of the limiting rod 6 is located in the supporting tube 4, the front end of the top surface of the limiting rod 6 contacts the top surface of the slot 3, the front end of the left side surface of the limiting rod 6 contacts the left side surface of the slot 3, the front end of the right side surface of the limiting rod 6 contacts the right side surface of the slot 3, and the front end of the top surface of the limiting rod 6 contacts the front side surface of the slot 3.

[0025] The driving member includes a rotating rod 8, which is a round rod. The rotating rod 8 is located between the two fixed plates 5 on the supporting tube 4. The two ends of the rotating rod 8 respectively penetrate the middle of the top plate and the bottom plate of the supporting tube 4. The lower end of the rotating rod 8 is rotatably connected to the bottom plate of the supporting tube 4 via a bearing 12. The front and rear ends of the peripheral wall of the rotating rod 8 are respectively connected with a pull rope 1 9 and a pull rope 2 10.

In the process of the supporting tube 4 extending downward into the corresponding receiving groove 2, the inclined front end surface of the limiting rod 6 at the front of the supporting tube 4 is pressed by the upper end of the front side surface of the receiving groove 2. After the limiting rod 6 is pressed, it moves backward, and the spring 7 connected to the limiting rod 6 is compressed. Similarly, the limiting rod 6 at the rear of the supporting tube 4 is pressed by the upper end of the rear side surface of the receiving groove 2 and moves forward. When the supporting tube 4 is completely located in the receiving groove 2, the front end opening of the supporting tube 4 is opposite to the card groove 3 on the front side of the receiving groove 2, and the limiting rod 6 at the front of the supporting tube 4 moves forward under the restoring force of the connected spring 7, and the front limiting rod The front end of the rod 6 extends into the slot 3 on the front side of the accommodating groove 2.
