The setting of the spring 84 allows the end ring 83 to be connected and used.

[0021] Please see Figure 1 , Figure 2 , Figure 3A moving mechanism 9 is provided on the base frame 1. The moving mechanism 9 includes a support frame 90. The support frame 90 is fixedly connected to the inner side wall of the base frame 1. A reinforcing rib 91 is fixedly connected to the surface of the support frame 90.

[0023] The specific implementation process of this utility model is as follows: In use, by pulling the end ring 83 to move to the left, the limiting rod 82 is moved along the inner wall of the fixed ear 81, causing the spring 84 to deform. Then, the clamp 4 is pushed to drive the washer 5 to pass through the threaded rod 6, so that the clamp 4 contacts the rotating end of the robotic arm 3. Then, the nut 7 is pushed to contact the threaded rod 6. Rotating the nut 7, under the threaded connection, the nut 7 can be fixed, and the clamp 4 can be fixed and installed for use. Then, the end ring 83 is loosened so that the spring 84 returns to its deformation, so that the limiting rod 82 is pulled to insert into the limiting hole 80, and the nut 7 is inserted for use, limiting the nut 7 and avoiding the problem of the nut 7 vibrating and loosening. The output shaft is driven by motor 92 to rotate, which in turn drives screw 93 to rotate. With the threaded connection, the movable frame 94 can be moved, allowing it to slide along the surface of movable plate 98 to ensure stable movement. This also drives roller 95 to move, eventually bringing roller 95 into contact with the ground and lifting the base frame 1 for easy relocation. Under the deformation of spring 99, movable plate 98 can be pushed to move guide plate 990, ensuring that guide plate 990 always slides on the surface of screw 93. This limits the rotation of screw 93, preventing centrifugal vibration and ensuring good driving effect of screw 93.
