The top end of the adjusting ring 16 is connected with the movable support 1 through an inclined assembly. The upper side of the inner wall of the movable support 1 is connected with an adapter 2 through a second transmission assembly. The middle inner wall of the right end of the movable support 1 is fixedly connected with a signal controller 6. Through the signal controller 6, signals of operation commands from the space station operation console and the ground operation console can be received, enabling the operator to control the start of the electrical components inside and outside the movable support 1. The right end of the adapter 2 is fixedly connected with a connecting arm 3. The right end of the connecting arm 3 is rotatably connected with a robotic arm body 4. The other end of the robotic arm body 4 is provided with an electric control gripper 5. The robotic arm body 4 and the electric control gripper 5 are existing mature technologies, and their operation modes will not be elaborated in detail.

[0024] Specifically, the first transmission component includes a second motor 14 fixedly connected to the inner wall of the right side at the bottom end of the mounting disc 7 and a gear ring 17 fixedly connected to the upper side of the outer wall of the adjusting ring 16. The driving end of the second motor 14 penetrates through the outer wall of the mounting disc 7 and is fixedly connected with a spur gear 15. The outer diameter of the spur gear 15 is meshed and connected to the right end of the outer diameter of the gear ring 17. Control the second motor 14 to start, so that the spur gear 15 rotates, thereby enabling the gear ring 17 to rotate. Furthermore, under the traction of the electric push rod 18 through the adjusting ring 16, the connecting ring 9 rotates, and then the movable support column 1 rotates, so as to adjust the general working direction of the device. The second transmission component includes a transmission bolt 13 rotatably connected to the inner wall of the top end of the movable support column 1 and penetrating through the upper and lower sides, and a first motor 10 fixedly connected to the inner wall of the upper side of the right end of the movable support column 1.

The driven bevel gear 12 is meshed with the driving bevel gear 11. Control the first motor 10 to start, so that the driving bevel gear 11 rotates, thereby enabling the driven bevel gear 12 to drive the transmission bolt 13 to rotate, and then enabling the adapter 2 to drive the robotic arm body 4 on one side of the connecting arm 3 to rotate, so as to perform a fine adjustment of the angle of the robotic arm body 4 in the general working direction.

[0025] Specifically, the tilting component includes electric push rods 18 rotatably connected to the left and right sides of the top end of the adjusting ring 16 and a connecting ring 9 fixedly connected to the bottom end of the movable support column 1. The other ends of the electric push rods 18 are respectively rotatably connected to the left and right sides of the bottom end of the connecting ring 9. Control one electric push rod 18 to push the connecting ring 9, while the other electric push rod 18 shortens the driving stroke, causing the movable support column 1 to tilt.

The upper side of the outer wall of the universal shaft 8 is located between the inner diameters of the connecting ring 9. The top end of the universal shaft 8 is embedded in the inner wall of the middle part of the bottom end of the movable support column 1. When the movable support column 1 tilts, the inner wall of the bottom end moves along the surface of the universal shaft 8. Then control the robotic arm body 4 to start, so that the electric control gripper 5 approaches the working position, and then start the electric control gripper 5 to clamp an object, thereby completing a display operation of the robotic arm.

[0026] Working principle: First, the movable support column 1 is installed at the designated station through the mounting plates on both sides of the mounting disc 7 in cooperation with bolts. The signal controller 6 can receive the signal of the operation command, enabling the operator to control the start of the electrical components inside and outside the movable support column 1. First, control the start of the second motor 14, so that the straight gear 15 rotates, thereby enabling the toothed ring 17 to rotate. Then, through the adjusting ring 16 and under the traction of the electric push rod 18, the connecting ring 9 rotates, and then the movable support column 1 rotates, thus adjusting the general working direction of the device. Then, control the start of the first motor 10, so that the driving bevel gear 11 rotates, thereby enabling the driven bevel gear 12 to drive the transmission bolt 13 to rotate, and then enabling the adapter 2 and the robotic arm body 4 on one side of the connecting arm 3 to rotate, so as to finely adjust the angle of the robotic arm body 4 in the general working direction. Then, control the electric push rod 18 on one side to push the connecting ring 9, while the electric push rod 18 on the other side shortens the driving stroke, causing the movable support column 1 to tilt. Then, control the start of the robotic arm body 4, so that the electric control jaw 5 approaches the working position, and then start the electric control jaw 5 to clamp the object, thus completing a display operation of the robotic arm.
