[0026] Working principle: When in use, first place the object between the two sets of limit clamping plates 14, then start the motor three 12, and drive the two-way screw 13 to rotate through the motor three 12.

After sliding a suitable distance, the two sets of limit clamping plates 14 will limit and fix the object. After fixing, start the motor one 3 again, and drive the screw 4 to rotate through the motor one 3. When the screw 4 rotates, it will drive the connecting rod 5 to slide upward inside the slide rail 2. During the upward sliding process, the connecting rod 5 will drive the installation box 6 and the fixed object to be lifted upward together. When the object needs to be turned, first start the motor two 7. When the motor two 7 works, it will drive the gear one 8 to rotate. When the gear one 8 rotates, it will drive the gear two 10 to rotate. During the rotation process, the gear two 10 will drive the cylinder 9 to rotate inside the installation box 6. During the rotation process, the cylinder 9 will drive the connecting shell 11 and the fixed object to rotate. After rotating to a suitable angle, turn off the motor two 7. When the robot base 1 is in use, the handle 19 can be turned in sequence to drive the threaded rod 17 to rotate inside the fixed plate 16. The threaded rod 17 will drive the anti-skid plate 18 to move downward during the rotation.
