[0024] In this embodiment: the drive motor 85, the output end of the motor 85 drives the second bevel gear 83 through the rotating shaft 84, the second bevel gear 83 drives the first bevel gear 82, the first bevel gear 82 drives the flat threaded disk 81, the flat threaded disk 81 pushes the moving block 7 while rotating, the moving block 7 moves closer to each other through the cooperation of the processing table 1, thereby clamping the outer surface of the controller housing 5, so that the user can process the inner wall of the controller housing 5.

[0025] Example 2

[0026] This embodiment aims to facilitate the solution of the problem of how to adjust the orientation of the gripper 6. This embodiment is an improvement based on Embodiment 1. For details, please refer to [link to Embodiment 1]. Figures 1-5 The elastic mechanism 9 includes two rectangular blocks 91 respectively disposed inside the gripper 6. The rectangular blocks 91 are fixedly connected to the moving block 7. Each gripper 6 has a matching rectangular groove 92 near the rectangular blocks 91.

A fixing rod 93 is fixedly connected to the top center of each rectangular block 91. The top of each fixing rod 93 passes through the gripper 6 and extends to the limiting plate 94. The limiting plate 94 is fixedly connected to the fixing rod 93. The gripper 6 can... Rotating around the fixed rod 93 and the limiting plate 94 as the center, the orientation of the gripper 6 is adjusted. A spring 95 is provided between the limiting plate 94 and the gripper 6. The spring 95 can apply a downward force to the gripper 6. The spring 95 is respectively sleeved on the outer surface of the fixed rod 93.

[0029] Rubber pads 10 are fixedly connected to the adjacent sides of the two grippers 6 to protect the controller housing 5 and prevent the grippers 6 from scratching the controller housing 5 and affecting the processing quality.

[0030] In this embodiment: the user can lift the gripper 6 upwards, and the gripper 6 slides upwards on the surface of the fixing rod 93, so that the rectangular groove 92 at the bottom of the gripper 6 separates from the rectangular block 91, and the positioning groove 962 separates from the positioning pin 961. Then, the gripper 6 is rotated 180 degrees around the fixing rod 93 and the limiting plate 94 as the center. Finally, the gripper 6 is released, the upward force of the gripper 6 disappears, the spring 95 elastically recovers, and then pushes the gripper 6 to slide downwards on the outer surface of the fixing rod 93, so that the rectangular groove 92 at the bottom of the gripper 6 fits on the surface of the rectangular block 91, and the positioning groove 962 fits on the surface of the positioning pin 961, thereby positioning and fixing the gripper 6 after adjusting its orientation. Therefore, when the two grippers 6 are far apart, the inner wall of the controller housing 5 can be fixed by the external support, which makes it convenient for the user to process the outer surface of the controller housing 5.
