[0023] The main body 1 includes an arc plate 11 and a connecting frame 12, which are used to provide a working environment for the entire device; the arc plate 11 is set in a fan-shaped plate shape; two arc plates 11 are symmetrically arranged up and down; a connecting frame 12 is fixedly arranged between the two arc plates 11, which is used to connect the two arc plates 11;

[0024] A first rotating shaft 2 and a second rotating shaft 3 are rotatably arranged in the vertical direction between the two ends of the two arc-shaped plates 11 along the arc direction; the two ends of the first rotating shaft 2 along the axial direction are rotatably connected to the two arc-shaped plates 11; the two ends of the second rotating shaft 3 along the axial direction are rotatably connected to the two arc-shaped plates 11; the fixing belt 5 is configured to be wide, and the two ends along the length direction are fixedly connected to the first rotating shaft 2 and the second rotating shaft 3 respectively.

[0025] In this embodiment, when fixing the rudder shaft, it is only necessary to start the motor 6, and the first rotating shaft 2 shrinks the fixing belt 5 to complete the fixing of the rudder shaft. When disassembling, the first rotating shaft 2 is reversed to easily remove the rudder shaft. The design of the fixing belt 5 enables the overall device to be applicable to rudder shafts of various specifications, with a simple structure, flexibility and practicality.

[0026] In a preferred embodiment, a third rotating shaft 4 is rotatably provided in the vertical direction at the middle portion between the two arc plates 11 along the arc direction; both ends of the third rotating shaft 4 along the axial direction are rotatably connected to the two arc plates 11 respectively.

[0027] Please refer to Figure 1 , Figure 2 In this embodiment, the third rotating shaft 4 is arranged to be closer to the center of the arc plate 11 along the diameter direction of the arc plate 11, and is not located at the center of the ring width of the arc plate 11.

[0028] In a preferred embodiment, a rubber ring 13 is fixedly provided on the outer wall of the third rotating shaft 4 ; one end of the rubber ring 13 close to the center of the arc plate 11 along the diameter direction of the arc plate 11 protrudes from the arc plate 11 .

[0029] Please refer to Figure 1 , Figure 2 In this embodiment, the third rotating shaft 4 is arranged close to the center of the arc plate 11, and one end of the rubber ring 13 surrounding the third rotating shaft 4 protrudes from the arc plate 11, so that it can be against the rudder shaft when fixing the rudder shaft, thereby fixing and protecting the rudder shaft.

[0030] In a preferred embodiment, the material of the fixing belt 5 is rubber.

[0031] In a preferred embodiment, the inner wall of the fixing belt 5 is provided with protrusions 14 arranged in an array.

[0032] Please refer to Figure 1 , Figure 2In this embodiment, the fixing belt 5 is used to wrap and fix the rudder shaft, and the protrusion 14 increases the friction between the two to prevent the rudder shaft from sliding down when it is fixed.

[0034] Please refer to Figure 1 , Figure 2 In this embodiment, the motor 6 is used to provide power support for the rotation of the first rotating shaft 2.

[0035] How this application works:

[0036] When fixing the rudder shaft: the rudder shaft is vertically placed between the arc plate 11 and the fixing belt 5, and the motor 6 is started. The motor 6 drives the first rotating shaft 2 to rotate, so that the end of the fixing belt 5 connected to the first rotating shaft 2 is wound around the outer wall of the first rotating shaft 2, and the remaining fixing belt 5 is contracted, so as to clamp and fix the rudder shaft, which is convenient for the processing of the rudder shaft;

[0037] When removing the rudder shaft: start the motor 6, which is a servo motor, and can drive the first rotating shaft 2 to rotate in the opposite direction, so that the wound fixing belt 5 is loosened, and the remaining fixing belt 5 becomes more. At this time, the rudder shaft is no longer clamped and fixed, and can be removed.
