[0002] Anthropomorphic robots are not only an important symbol of a country's comprehensive high-tech level, but also have a wide range of uses in human production and life. According to the announcement number: CN204658456U, a high-simulation robot is disclosed. It includes a body assembly consisting of a head, a trunk and limbs, the outer surface of the body assembly is covered with simulated skin, the head is provided with a simulated skull, the trunk is provided with a simulated spine and simulated ribs, the limbs are provided with simulated arm bones or simulated femurs, the trunk is provided with a vacuum power device and multiple piston-type wire pulling mechanisms, the piston-type wire pulling mechanism is composed of a cylindrical shell with two ends closed and a piston installed in the inner cavity of the cylindrical shell, one end of the cylindrical shell is connected to the vacuum tank through a three-way valve, and the other end is provided with a wire skin and a wire, and the inner end of the wire is fixedly connected to the piston. The highly realistic robot has a simple structure, small size, and light weight. It can manipulate limb movements more flexibly, faster, more accurately, more powerfully, and more elastically. It has a high degree of simulation and is more like a real person in both appearance and movement. However, the above technology still has some defects. For example, the mechanical arms of existing robots are mostly directly fixed on both sides of the torso. After long-term use, when maintenance is required, the mechanical arms cannot be disassembled, which causes inconvenience in maintenance. The robot is not practical and needs to be improved.

A protective cover 22 is fixedly installed on the left side of the sliding plate 20 to better protect the motor B9. Before use, pinch the protective cover 22 to match the sliding plate 20 to the upper limit slot 19 and press downward, so that the sliding plate 20 slides downward at the top of the limit plate 18 through the limit slot 19. When the sliding plate 20 completely slides into the interior of the limit plate 18 through the limit slot 19, it is ready, and at this time, the sliding plate 20 drives the soft pad 21 to completely slide into the limit plate 18, so that the soft pad 21 firmly clamps the sliding plate 20 inside the limiting plate 18, thereby preventing the motor B9 from being unable to continue rotating due to dust floating into the inside of the motor B9 during use. The limiting plates 18 are symmetrically distributed at the left and right ends of the robot trunk 1, and the sliding plate 20 is slidably connected to the limiting plate 18, the soft pad 21 is slidably connected to the limiting plate 18, and the protective cover 22 is slidably connected to the limiting plate 18, which makes it easier for the sliding plate 20 and the soft pad 21 to slide, and avoids the sliding plate 20 and the soft pad 21 being stuck by the limiting plate 18 during use, causing the sliding plate 20 and the soft pad 21 to be unable to continue sliding.

[0027] Working principle: Before use, pinch the protective cover 22 and correspond the sliding plate 20 to the upper limit groove 19 and press downward, so that the sliding plate 20 drives the soft pad 21 to slide downward at the top of the limit plate 18 through the limit groove 19. When the sliding plate 20 drives the soft pad 21 to slide completely into the interior of the limit plate 18 through the limit groove 19, the sliding plate 20 can firmly clamp the protective cover 22 in the middle of the limit plate 18, thereby protecting the motor B9. After long-term use, when the motor B9 needs to be maintained, the handle 17 can be rotated with the help of a tool to make the threaded rod 16 rotate backward inside the robot trunk 1 through the rotating groove 15. At this time, the handle 17 is rotated out of the robot trunk through the groove 14. 1, and the threaded rod 16 rotates out of the robot body 1 through the rotating groove 15, and rotates out of the mounting block 3 through the card slot 13, and then pinches the rotating block 7 and pulls it to the side, so that the mounting block 3 slides out of the robot body 1 through the mounting groove 2. At this time, the motor A6 inside the mounting block 3 can be maintained through the fixed groove 5, and the motor B9 can be maintained, and the motor A6 can be started when in use. At this time, the motor A6 can drive the rotating block 7 to rotate through the rotating groove A4, and the rotating block 7 drives the mechanical arm 12 to rotate through the fixed block 11, and then the motor B9 is started again, so that the rotating rod 10 drives the fixed block 11 to rotate inside the rotating block 7 through the rotating groove B8, and the left and right adjustment of the mechanical arm 12 can be completed.
