[0024] Specifically, the dual-axis motor 201 is turned on, and the dual-axis motor 201 drives the two threaded rods 202 to rotate. The rotation of the two threaded rods 202 drives the movable plate 205 to move through the threaded block 203 and the connecting rod 204, and then the distance between the two movable plates 205 is adjusted according to the length of the driving shaft body 4.
[0025] Two sliding grooves are provided on the top surface of the base 1 , and the tops of the two connecting rods 204 are fixedly connected to the bottom of the moving plate 205 .
[0026] Specifically, the slide groove is provided so that the connecting rod 204 can slide inside the slide groove when moving, thereby driving the moving plate 205 to move.
[0027] The locking assembly 3 includes two cavities 301, and the two movable plates 205 are each provided with a cavity 301. Servo motors 302 are fixedly installed on the inner top walls of the two cavities 301. Gears 303 are fixedly installed on the output shafts of the two servo motors 302. Two tooth plates 304 are meshed on the outer surfaces of the two gears 303. Two clamping plates 305 are movably installed on the opposite sides of the two movable plates 205.
[0028] Specifically, when the two servo motors 302 are turned on, the two tooth plates 304 are driven to approach each other, so that every two clamping plates 305 move relative to each other to clamp the drive shaft body 4. The drive shaft body 4 is locked by the support of the two clamping plates 305 to facilitate the next step of processing.

[0030] Specifically, the clamping plate 305 can be driven to move by the connecting block when the tooth plate 304 moves, and the connecting block will slide inside the movable groove when moving.
[0031] Each clamping plate 305 is designed as an arc-shaped plate, and anti-skid pads are installed on opposite sides of every two clamping plates 305, and both ends of the driving shaft body 4 are in contact with the surface of the protective pads.
[0032] Specifically, the clamping plate 305 is configured to be arc-shaped, so that it can better fit the appearance of the driving shaft body 4 and achieve a better clamping effect.
[0033] When implementing, follow these steps:

When adjusting, it is only necessary to turn on the dual-axis motor 201, and the dual-axis motor 201 drives the two threaded rods 202 to rotate. The rotation of the two threaded rods 202 drives the movable plate 205 to move through the threaded block 203 and the connecting rod 204, so as to adjust the distance between the two movable plates 205.
