The height of the outer shell 4 is greater than the height of the inner shell 3. The upper end of the inner shell 3 is an open end, and the upper end of the outer shell 4 is a closed end. The lower end of the inner shell 3 passes through the upper surface of the base 2 and is fixed in the base 2 by bolts. A partition 31 is arranged in the position near the upper end of the inner shell 3, and an electric push rod 5 for driving the outer shell 4 to rise and fall along the inner shell 3 is installed on the partition 31. The push rod 51 of the electric push rod 5 passes through the upper end of the inner shell 3 and is fixedly connected to the top of the outer shell 4. The outer shell 4 is lifted and lowered by the extension and retraction of the push rod 51 of the electric push rod 5. The electric push rod 5 can also be installed on the top of the outer shell 4. The push rod 51 of the electric push rod 5 passes through the upper end of the inner shell 3 and is fixedly connected to the partition 31 of the inner shell 3. In this way, the outer shell 4 can also be lifted and lowered by the extension and retraction of the push rod 51.

[0033] like Figure 1-Figure 2 As shown, multiple elastic buffer pads 6 are respectively arranged on each outer side wall of the inner shell 3, and the multiple elastic buffer pads 6 are arranged vertically and spaced apart on the corresponding outer side wall of the inner shell 3, and each elastic buffer pad 6 is provided with multiple arc-shaped buffer convex strips 61 elastically contacting with the corresponding inner side wall of the outer shell 4. By arranging the elastic buffer pads 6 on the outer side wall of the inner shell 3, the arc-shaped buffer convex strips 61 on the elastic buffer pads 6 can be elastically deformed during the lifting process of the outer shell 4, ensuring that the outer shell 4 is always in elastic contact with the corresponding elastic buffer pads 6 during the lifting process, thereby ensuring the stability of the lifting.

[0034] A hanging arm 41 for hanging the sandbag 1 is provided on one side of the upper end of the outer shell 4. The sandbag 1 is connected to the hanging arm 41 through a hanging ring 7. An oblique support arm 42 is connected between the outer shell 4 and the hanging arm 41 to increase the hanging strength of the hanging arm 41.

[0035] The outer shell 4 is symmetrically provided with a mounting arm 43 on both sides corresponding to the bottom of the sandbag 1, and the angle between each mounting arm 43 and one side of the sandbag 1 is 90°. Each mounting arm 43 is provided with a group of shock absorbing mechanisms for buffering the force applied to the sandbag 1. The two groups of shock absorbing mechanisms are symmetrically arranged, and each group of shock absorbing mechanisms includes two damping shock absorbers 8, a total of four damping shock absorbers, each damping shock absorber 8 has a fixed end and a movable end, and the movable ends of the two damping shock absorbers 8 in each group of shock absorbing mechanisms are crossed up and down, and two sleeve rods 11 corresponding to each group of shock absorbing mechanisms are respectively provided at the bottom of the sandbag 1, and the movable ends of the damping shock absorbers 8 are respectively sleeved with the corresponding sleeve rods 11. The fixed ends of the two damping shock absorbers 8 in each set of shock absorbing mechanisms are rotatably fixed to the corresponding positions of the same corresponding mounting arm 43, and the angle between the two damping shock absorbers 8 is 15°, so that the expansion and contraction of the movable ends of the damping shock absorbers 8 can be used to achieve a good shock absorbing and buffering effect on the sandbag 1, ensuring that the sandbag 1 does not shake. The fixed ends of the two damping shock absorbers 8 in each set of shock absorbing mechanisms can also be arranged to be rotatably fixed to the corresponding positions of different mounting arms 43, and the angle between the two damping shock absorbers 8 can be adjusted to achieve the shock absorbing and buffering effect on the sandbag 1.

The controller is arranged in the base 2, and the remote control switch is at least one of a wired remote control switch and a wireless remote control switch. When a wired remote control switch is selected, the wired remote control switch can be installed on the base 2.

[0037] In this embodiment, the sandbag 1 is in a human-like shape. The sandbag 1 can also be set to other common shapes such as a cylinder.

[0038] After adopting the above structure, the present invention provides a multifunctional sandbag hanging device, in which the columns of the sandbag frame are arranged in a form in which the inner shell 3 and the outer shell 4 are socketed. The outer shell 4 can be raised and lowered along the inner shell 3 under the push of the electric push rod 5. The sandbag 1 is hung on the hanging arm 41 of the outer shell 4, so as to adjust the height of the sandbag 1. Two groups of shock absorbing mechanisms are also arranged on the outer shell 4. The damping shock absorber 8 in each group of shock absorbing mechanisms can play a shock absorbing and buffering role for the sandbag 1 subjected to the impact force, prevent the sandbag 1 from shaking significantly, thereby extending the service life of the sandbag 1. At the same time, it can also ensure the accuracy of the force sensor sensing in the sandbag 1.
