[0025] The effect achieved by the entire embodiment 1 is as follows: Figure 3 and Figure 1As shown, when the rotating shaft 13 is rotated forward or reversed by the dual-axis motor 14, the threaded rod 12 will be driven to rotate, and the threaded rod 12 can drive the slider 3 to slide back and forth in the slide groove 11, and the slider 3 will drive the connecting plate 4, the connecting rod 5 and the rubber clamp 6 to move. Since the first half shaft 1 and the second half shaft 18 are fixed in the two rubber clamps 6, the first half shaft 1 and the second half shaft 18 are driven together by force, so that precise alignment can be achieved during assembly, which can reduce the dependence on the technician's hand feel.

[0026] Embodiment 2, as Figure 1-Figure 5 As shown, the outer surface of the threaded rod 12 is threaded through the outer surface of the slider 3, one end of the rotating shaft 13 is fixedly connected to the output end of the dual-axis motor 14, the other end of the rotating shaft 13 is fixedly connected to the outer surface of the threaded rod 12, the outer surface of the rubber clamp 6 is slidably connected to the outer surfaces of the first semi-shaft 1 and the second semi-shaft 18, the outer surface of the rubber clamp 6 is fixedly connected with a connecting block 8 near the bottom front and back, the center of the front outer surface of the connecting block 8 is threadedly penetrated with a first bolt 7, the front outer surface of the connecting block 8 is provided with a first threaded hole 9 at the position of the first bolt 7, the inner surface wall of the first threaded hole 9 is connected to the outer surface of the first semi-shaft 18, and the inner surface wall of the first threaded hole 9 is connected to the outer surface of the first semi-shaft 18.

After inserting, screw the first bolt 7 into the corresponding first threaded hole 9, and screw it in to achieve that the first half-shaft 1 and the second half-shaft 18 can be stably in the two rubber clamps 6, and then the dual-axis motor 14 starts to run, so that the rotating shaft 13 can rotate forward or reverse, and the rotating shaft 13 will also drive the threaded rod 12 to rotate, and its rotating shaft body 10 is rotated together with the force, so that the slider 3 can move back and forth in the slide groove 11 When sliding, the connecting rod 5, the connecting plate 4, the rubber clamp 6, the first semi-axle 1 and the second semi-axle 18 can be translated. After a certain translation position, the clamping block 19 can be inserted into the clamping groove 16. After being inserted, the user screws the second bolt 15 into the corresponding second threaded hole 17 to achieve that the first semi-axle 1 and the second semi-axle 18 can be stably spliced ​​together. Then the user unscrews the first bolt 7 to separate the rubber clamp 6 from the first semi-axle 1 and the second semi-axle 18 to complete the overall disassembly. After the overall operation is completed, it can be accurately aligned and fixed in place during assembly, reducing the dependence on the technician's hand feel.
