[0034] The limiting mechanism includes a moving rod 6, which passes through and is slidably connected to the inner wall of the support frame 2. A slot corresponding to the moving rod 6 is opened on the support frame 2, which can meet the vertical movement of the moving rod 6 along the support frame 2. The bottom end of the moving rod 6 is elastically connected to the support frame 2 through a return spring 5. The bottom end of the moving rod 6 is fixedly connected to a wedge block 7. The wedge block 7 is an inclined surface. When the inclined surface is squeezed, the wedge block 7 will move the moving rod 6 along the inner wall of the support frame 2.

[0035] Reference Figure 1 、 Figure 5 and Figure 6 The connecting assembly includes an insertion rod 9, which is fixedly connected to the top of the moving wheel 8. The inner wall of the left end of the insertion rod 9 is elastically connected to a pressing plate 11 through a positioning spring 10. The pressing plate 11 can move laterally along the inner wall of the insertion rod 9 with a card block 12. The right end of the pressing plate 11 is fixedly connected with a card block 12. The inner wall of the left end of the insertion rod 9 is fixedly connected to one end of the positioning spring 10. When the pressing plate 11 moves to the left, the positioning spring 10 is compressed. When resetting, the reverse elastic force of the positioning spring 10 is used to reset the pressing plate 11. The other end of the positioning spring 10 is fixedly connected to the left end of the pressing plate 11.

[0036] The pressing plate 11 passes through and is slidably connected to the inner wall of the insertion rod 9. The insertion rod 9 is provided with a notch corresponding to the pressing plate 11, which can satisfy the left and right movement of the pressing plate 11. The card block 12 passes through and is slidably connected to the inner wall of the insertion rod 9. The insertion rod 9 is provided with a notch corresponding to the card block 12, which can allow the card block 12 to be exposed and plugged into the inner wall of the connecting frame 1. The card block 12 is plugged into the inner wall of the connecting frame 1, and the insertion rod 9 is plugged into the inner wall of the connecting frame 1. The connecting frame 1 is provided with notches corresponding to the insertion rod 9 and the card block 12, such as Figure 6 shown.

[0037] Reference Figure 2-Figure 4The bottom end of the moving rod 6 is fixedly connected to one end of the reset spring 5. When the moving rod 6 moves upward, the reset spring 5 is stretched. When resetting, the reverse elastic force of the reset spring 5 is used to reset the moving rod 6. The other end of the reset spring 5 is fixedly connected to the top inner wall of the support frame 2. The wedge 7 passes through and is slidably connected to the inner wall of the support frame 2. The wedge 7 is inserted into the side wall of the placement frame 4. Figure 2 As shown, the side wall of the placement frame 4 has a raised portion, and a notch corresponding to the wedge block 7 is opened on the raised portion.

[0038] Working principle: First, when it is necessary to add or reduce the placement frame 4 according to the amount of transported drugs, it is only necessary to insert the added placement frame 4 into the support frame 2, and let the outer wall of the placement frame 4 squeeze the inclined surface of the wedge block 7 and stretch the reset spring 5, so that the wedge block 7 moves upward with the moving rod 6 to allow the wedge block 7 to be retracted into the support frame 2. When the placement frame 4 is completed and connected with the fixed frame 3, the notch on the side wall of the placement frame 4 coincides with the wedge block 7, and the elastic force of the reset spring 5 is used to move the moving rod 6 and the wedge block 7 downward to allow the wedge block 7 to be inserted into the notch on the side wall of the placement frame 4 to complete the one-way limiting of the placement frame 4. If it is necessary to reduce the placement frame 4, it is only necessary to move the moving rod 6 upward to move the wedge block 7 upward and stretch the reset spring 5 to separate the wedge block 7 from the notch on the side wall of the placement frame 4, and then move one group of placement frames 4 or multiple groups of placement frames 4 out of the notch of the fixed frame 3 and the support frame 2 at the same time.

[0039] When the moving wheel 8 needs to be replaced or maintained, it is only necessary to press the pressing plate 11 to allow the pressing plate 11 to move the card block 12 to the left and compress the positioning spring 10, so that the card block 12 is retracted into the insertion rod 9, so that the slot of the connecting frame 1 and the card block 12 are separated, and finally the insertion rod 9 is removed from the inner wall of the connecting frame 1. During installation, it is only necessary to keep the card block 12 in a pressed state to allow the insertion rod 9 and the connecting frame 1 to be plugged in. When the card block 12 coincides with the slot of the inner wall of the connecting frame 1, release the pressing plate 11 and use the elastic force of the positioning spring 10 to restore the pressing plate 11 and the card block 12 to their original position, and allow the card block 12 to be inserted into the inner wall of the connecting frame 1 to complete the installation of the moving wheel 8.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
