[0023] Specifically, first, the base plate 1 is firmly installed at the position to be processed; next, the transmission shaft is placed above the rotating wheel 1203; then, by starting the motor 3, the connecting rod 5 on the outer wall of the connecting shaft 4 is driven to rotate smoothly; the rotation of the connecting rod 5 further drives the connecting plate 6, so that the connecting rod 7 slides within the mounting shell 2, thereby achieving the effect of precise adjustment according to the length of the transmission shaft; at the same time, by turning the knob 10, the screw rod 9 is limited by the telescopic rod 1201, driving the lifting plate 1202 to move up and down, thereby achieving the effect of precise adjustment according to the different diameters of the transmission shaft; in this way, through a series of operations and adjustments, it can be ensured that the transmission shaft is always in the best position and state during the processing, thereby improving the processing accuracy and efficiency.

[0024] Reference Figure 1 , Figure 2 and Figure 3 , the upper surface of the mounting shell 2 is fixedly connected with a left-right symmetrical electric slide rail 13, and the outer wall of the electric slide rail 13 is slidably connected with an electric slider 24; one side of the upper surface of the electric slider 24 is fixedly connected with a left-right symmetrical hinge seat 14, and the hinge seat 14 is rotatably connected with a support plate 15; one side of the support plate 15 is fixedly connected with a motor 2 16, and the output end of the motor 2 16 is fixedly connected with a rotating shaft 17, and the rotating shaft 17 is rotatably connected to the inside of the support plate 15, and the outer wall of the rotating shaft 17 is fixedly connected with an auxiliary wheel 18; the other side of the upper surface of the electric slider 24 is fixedly connected with a hinge seat 2 19, and the hinge seat 2 19 is rotatably connected with a hinge block 1 20; one side of the outer wall of the hinge block 1 20 is fixedly connected with an electric push rod 21, and the output end of the electric push rod 21 is fixedly connected with a hinge block 22; the support plate 15 is rotatably connected with a transmission rod 23, and the hinge block 22 is rotatably connected to the outer wall of the transmission rod 23;

[0025] Specifically, when the transmission shaft is stable, the electric slide rail 13 is first started to drive the electric slider 24 to slide smoothly, thereby achieving a precise adjustment effect according to the length of the transmission shaft; then, the electric push rod 21 is started to make the hinge block 1 20 rotate smoothly inside the hinge seat 2 19, thereby driving the transmission rod 23 inside the hinge block 22 to move smoothly, thereby achieving precise adjustment of the angle of the support plate 15; through the movement of the support plate 15, the auxiliary wheel 18 is driven to clamp the transmission shaft downward to ensure the stability of the transmission shaft; at the same time, the motor 2 16 is started to drive the auxiliary wheel 18 to rotate smoothly; due to the friction between the auxiliary wheel 18 and the transmission shaft, the transmission shaft is further driven to rotate on the outer wall of the rotating wheel 1203, thereby achieving the effect of multi-angle rotating transmission shaft for processing; this series of operations ensures that the transmission shaft can be accurately adjusted and stably rotated as needed during the processing process, thereby improving the flexibility and accuracy of the processing.

[0026] Working principle: When in use, first install the bottom plate 1 at the position to be processed, then place the transmission shaft above the rotating wheel 1203, and then start the motor 3 to drive the outer wall connecting rod 5 of the connecting shaft 4 to rotate, and then drive the connecting plate 6 to drive the connecting rod 7 to slide within the installation shell 2 through the rotation of the connecting rod 5, thereby achieving the effect of adjusting according to the length of the transmission shaft, and at the same time, by rotating the knob 10, the screw rod 9 drives the lifting plate 1202 to move up and down under the limit of the telescopic rod 1201, thereby achieving the effect of adjusting according to the different diameters of the transmission shaft;

[0027] Secondly, when the transmission shaft is stable, the electric slide rail 13 is started to drive the electric slider 24 to slide, thereby achieving the effect of adjusting the length of the transmission shaft. At the same time, the electric push rod 21 is started to make the hinge block 1 20 rotate inside the hinge seat 2 19, and then the transmission rod 23 inside the hinge block 22 is driven to move, thereby achieving the effect of adjusting the angle of the support plate 15. Through the movement of the support plate 15, the auxiliary wheel 18 is driven to clamp the transmission shaft downward. At the same time, the auxiliary wheel 18 is driven to rotate by starting the motor 2 16. Due to the friction between the auxiliary wheel 18 and the transmission shaft, the transmission shaft is driven to rotate on the outer wall of the rotating wheel 1203, so as to achieve the effect of rotating the transmission shaft at multiple angles for processing.
