By the rebounding mode of the guide blocks 44, the guide blocks 44 push the lifting plate 41 to move longitudinally towards the direction of approaching the lead bucket barrel cover 3, so that the storage device 1 placed on the top end of the lifting plate 41 is pushed to the top of the lead bucket barrel 2, thereby reducing the case that the staff needs to bend over greatly to stretch the arm into the inside of the lead bucket barrel 2 in order to take out the medicine. By placing the storage device 1 for storing medicine on the top end of the lifting plate 41, and then pressing the pressing rod 61, the guide blocks 44 are extruded and vertically move away from the lead bucket barrel cover 3, until the pressing rod 61 cannot continue to move vertically, then the pressing rod 61 is rotated, the pressing rod 61 drives the insertion rod 62 to rotate, the insertion rod 62 drives the locking block 63 to rotate into the clamping groove 7, when the locking block 63 is blocked by the clamping groove 7 and cannot continue to rotate, the top end of the inner wall of the clamping groove 7 and the top end of the locking block 63 are mutually attached, thereby limiting the vertical movement of the locking block 63, the locking block 63 limits the movement of the pressing rod 61 through the insertion rod 62, the bottom end of the pressing rod 61 and the top end of the guide block 44 are attached, thereby limiting the vertical movement of the lifting plate 41, and the storage device 1 is stored in the inside of the lead bucket barrel 2. When the storage device 1 needs to be taken out, the pressing rod 61 is rotated in the opposite direction, the locking block 63 moves out of the clamping groove 7, under the action of the rebounding force of the main spring 42, the lifting plate 41 is pushed to move towards the direction of approaching the lead bucket barrel cover 3, the lifting plate 41 drives the storage device 1 to move synchronously, thereby pushing the storage device 1 to the top of the lead bucket barrel 2, so that the staff can reduce the case of bending over greatly to take out the storage device 1, and reduce the damage to the waist.

[0027] Further, the storage device 1 is a storage container for existing radioactive medicine, and the lead bucket barrel 2 and the lead bucket barrel cover 3 are existing lead buckets for isolating the radioactivity of the radioactive medicine.

By sleeving the secondary spring 43 in the inside of the primary spring 42, the lifting plate 41 can be prevented from swinging greatly under the restoring force of the primary spring 42 under the action of two springs with different stiffness. The primary spring 42 and the secondary spring 43 are coaxially nested, and the distance between the primary spring 42 and the secondary spring 43 is 0.1mm, so as to avoid the contact friction between the primary spring 42 and the secondary spring 43. The primary spring 42 is used to bear static pressure, and the secondary spring 43 is used to provide damping and absorb high-frequency vibration. The stiffness of the primary spring 42 is greater than that of the secondary spring 43, and the number of turns of the secondary spring 43 is greater than that of the primary spring 42. For example, the stiffness of the primary spring 42 is 8N / mm, and the stiffness of the secondary spring 43 is 2N / mm. The number of turns of the primary spring 42 is 4 turns, and the number of turns of the secondary spring 43 is 8 turns. The primary spring 42 responds to low-frequency pressure changes and maintains the stability of contact. The secondary spring 43 is more sensitive to deformation under high-frequency vibration due to its low stiffness and large number of turns, and provides damping effect and energy absorption. The top end and the bottom end of the primary spring 42 and the secondary spring 43 are respectively bonded with the bottom end of the lifting plate 41 and the bottom end of the inner wall of the lead barrel body 2.

[0032] Further, in order to limit the movement of the penetrating rod 62, the outer wall of the penetrating rod 62 is fixedly connected with a locking block 63, and one side of the inner wall of the guide groove 5 is provided with a clamping groove 7 for clamping the locking block 63. By rotating the pressing rod 61, the pressing rod 61 drives the penetrating rod 62 to rotate, so that the locking block 63 on the outer wall of the penetrating rod 62 rotates to the inside of the clamping groove 7, thereby limiting the vertical movement of the penetrating rod 62, limiting the vertical upward movement of the lifting plate 41, and ensuring the storage of the storage device 1 in the barrel body 2. The end of the locking block 63 is welded and fixed with the outer wall of the penetrating rod 62, the clamping groove 7 is an arc-shaped groove, and the clamping groove 7 is arranged at the end of the inner wall of the guide groove 5 away from the barrel cover 3.
