[0032] A second plug rod 141 is fixedly connected to the bottom end of the second column 14, a replacement hole 151 is vertically opened on the top wall of the replacement column 15 at a position relative to the second plug rod 141, and a replacement transverse hole 152 is horizontally opened on the side wall of the replacement hole 151, a replacement rod 153 is horizontally inserted inside the replacement transverse hole 152, and a through hole is horizontally opened at the position of the second plug rod 141 relative to the replacement rod 153. When the second plug rod 141 is extended into the replacement hole 151, the replacement rod 153 can be extended into the through hole of the second plug rod 141 to fix the second plug rod 141, thereby relatively connecting the second column 14 and the replacement column 15.

[0033] A replacement plug rod 154 is fixedly connected to the bottom end of the replacement column 15, a first plug hole 131 is vertically opened on the top wall of the first column 13 at a position relative to the replacement plug rod 154, and a first transverse hole 132 is horizontally opened on the side wall of the first plug hole 131, a first rod 133 is horizontally inserted inside the first transverse hole 132, and a through hole is horizontally opened at the position of the replacement plug rod 154 relative to the first rod 133. When the first rod 133 extends into the first plug hole 131, the first rod 133 can extend into the through hole of the replacement plug rod 154 to fix the replacement plug rod 154, thereby connecting the replacement column 15 to the first column 13 relatively.

[0034] Reference Figure 1 , Figure 2 A C-shaped groove 16 is provided on the side walls of the first column 13, the replacement column 15 and the second column 14. The interiors of the first column 13, the replacement column 15 and the second column 14 are hollow structures, and the interiors of the first column 13, the replacement column 15 and the second column 14 are relatively connected to the outside through the C-shaped groove 16.

[0035] The lifting assembly 3 includes a transmission shaft 31 located inside the column 1, and a base plate 32 is horizontally arranged at the bottom end of the transmission shaft 31. The base plate 32 is a circular structure, and the base plate 32 and the transmission shaft 31 are coaxially arranged. A first rotating motor is arranged below the base plate 32, and the motor shaft of the first rotating motor is coaxially arranged with the transmission shaft 31 and relatively fixedly connected. A second rotating motor is also arranged below the base plate 32, and the motor shaft of the second rotating motor is coaxially arranged with the base plate 32 and relatively fixedly connected.

[0037] A slide 33 is provided on the outer wall of the transmission shaft 31 , and the slide 33 includes an ascending slide and a descending slide which are relatively parallel to each other at the bottom ends. The ascending slide 33 and the descending slide 33 are relatively connected at the top of the slide 33 , and the slide 33 is spirally arranged along the outer wall of the transmission shaft 31 .

[0038] The two ends of the hanger 2 are respectively fixedly connected with a hanger ring 21, which is an annular structure and is sleeved on the outside of the transmission shaft 31. The inner wall of the hanger ring 21 is fixedly connected with a slider at a position relative to the slideway 33. The slider is located inside the slideway 33 and is relatively slidably connected. When the transmission shaft 31 is rotated, the slideway 33 pushes the slider to move inside the slideway 33, thereby driving the hanger 2 to move along the height direction of the transmission shaft 31.

[0039] Reference Figure 2 , Figure 4 A clamping plate 23 is fixedly connected to the top of the side wall of the hanger ring 21. Multiple clamping plates 23 are arranged equidistantly along the circumference of the hanger ring 21, and the clamping plates 23 are of an "L"-shaped structure. A clamping slot 17 is provided at the top of the inner side wall of the second column 14 at a position relative to the clamping plate 23. An adjustment plate 18 is vertically arranged inside the clamping slot 17. The sides and the top of the adjustment plate 18 are spaced from the side walls of the clamping slot 17. The inside of the clamping slot 17 is divided into an entry portion 171 and an exit portion 173 located on both sides of the adjustment plate 18, and a clamping portion 172 located at the top of the adjustment plate 18. The entry portion 171 is relatively connected to the clamping portion 172, and the exit portion 173 is relatively connected to the clamping portion 172.

[0040] A limiting groove 181 is provided at the top of the adjustment plate 18. When the card plate 23 enters the clamping portion 172 from the position of the entry portion 171, the card plate 23 is limited by the limiting groove 181. After being limited, the card plate 23 is moved upward so that the card plate 23 re-enters the interior of the clamping portion 172, and then enters the interior of the exit portion 173 through the guidance of the clamping portion 172.

[0041] The bottom end of the adjustment plate 18 is a deformable elastic structure. In the initial state, the bottom end of the adjustment plate 18 contacts the side wall of the limiting groove 181 close to the exit portion 173, so that one side of the entry portion 171 is opened, and the clamping plate 23 can enter the inside of the clamping portion 172 through the entry portion 171. When the clamping plate 23 moves downward from the exit portion 173, it pushes the bottom end of the adjustment plate 18 to move toward the side close to the entry portion 171, so that the bottom end of the exit portion 173 is opened, and then the clamping plate 23 can be separated from the inside of the exit portion 173. The detached clamping plate 23 abuts against the side wall of the limiting groove 181 close to the exit portion 173 again under the action of elastic deformation.

[0042] Reference Figure 2 , Figure 5 The locking assembly 4 includes a first locking plate 41 and a second locking plate 42 which are relatively arranged on the bottom plate 32. The first locking plate 41 and the second locking plate 42 are arc-shaped structures, and the center of the arc is the same as the axis of the transmission shaft 31. The first locking plate 41 and the second locking plate 42 are sleeved on the outside of the transmission shaft 31.

[0043] A spring 43 is disposed at one end of the first locking plate 41 and the second locking plate 42. One end of the spring 43 is fixedly connected to the first locking plate 41, and the other end of the spring 43 is fixedly connected to the second locking plate 42. One end of the first locking plate 41 close to the spring 43 is rotatably connected to the bottom plate 32, and one end of the second locking plate 42 close to the spring 43 is rotatably connected to the bottom plate 32.

[0044] A driving groove 321 is formed on the bottom plate 32 at one end of the first locking plate 41 away from the spring 43 . The driving groove 321 is a strip-shaped groove body and is inclined along the circumference of the bottom plate 32 from the side close to the center of the bottom plate 32 toward the side away from the center of the bottom plate 32 .

[0045] A driving column 44 is vertically arranged inside the driving groove 321, and the driving column 44 is slidably connected to the bottom plate 32. A first driving rod 441 is fixedly connected to the driving column 44, and one end of the first driving rod 441 away from the driving column 44 is rotatably connected to the first locking plate 41. A second driving rod 442 is also fixedly connected to the driving column 44, and one end of the second driving rod 442 away from the driving column 44 is rotatably connected to the second locking plate.

[0046] The second rotating motor drives the bottom plate 32 to rotate, and then the driving slot 321 on the bottom plate 32 drives the internal driving column 44 to move along the direction of the driving slot 321. When the driving column 44 is located at the end of the driving slot 321 close to the center of the bottom plate 32, the driving column 44 drives the first driving rod 441 and the second driving rod 442 to be located at the end close to the center of the bottom plate 32, so that the first locking plate 41 and the second locking plate are opened, and the transmission shaft 31 can rotate freely. When the driving column 44 is located at the end of the driving slot 321 away from the center of the bottom plate 32, the driving column 44 drives the first driving rod 441 and the second driving rod 442 to be located at the end away from the center of the bottom plate 32, so that the first locking plate and the second locking plate hold the transmission shaft 31 tightly, thereby limiting the rotation of the transmission shaft 31.

[0047] The hanger 2 includes a first hoisting portion 24 and a second hoisting portion 25 which are arranged horizontally. The first hoisting portion 24 and the second hoisting portion 25 are rotatably connected, and the first hoisting portion 24 and the second hoisting portion 25 are connected by a latch so that they can rotate relative to each other. A lifting ring 26 is fixedly connected to the bottom end of the first hoisting portion 24, and an object to be hoisted from the outside can be hoisted through the provided lifting ring 26.
