[0006] Preferably, an inlet and outlet through hole is opened at the upper end of the oil cylinder body, and the limit pin extends out of the oil cylinder body through the inlet and outlet through hole, and the limit pin can move up and down in the oil cylinder body.
[0007] Preferably, an inlet and outlet through hole is opened at the upper end of the oil cylinder body, and the limit pin extends out of the oil cylinder body through the inlet and outlet through hole. The limit pin can limit the hollow shaft body on the solid shaft body.
[0008] Preferably, the limit pin is movably installed in the cylinder body through the piston block, one end of the return spring is fixedly installed at the bottom of the cylinder body, and the other end of the return spring is fixed to the piston block. The limit pin is embedded in the hollow shaft body through the limit hole, and the return spring provides elastic force for the piston block, so that the piston block has a tendency to move downward.
[0009] Preferably, a detection port is provided on the connecting pipe, and the hydraulic sensor is installed on the connecting pipe through the detection port. The hydraulic sensor can detect the oil pressure inside the cylinder body.
[0010] Preferably, the inner side of the sealing end cover is provided with threads, and the sealing end cover is installed on the control pipe through the threads.

[0012] Compared with the prior art, the beneficial effects of the present invention are:
[0013] 1. In this application, hydraulic oil is injected into the cylinder body through a control pipe. This injection of hydraulic oil causes the piston block to move upward. As the piston block rises, it drives the limit pin upward and eventually engages in the limit hole, allowing the hollow shaft to be quickly secured to the solid shaft for use.
[0014] 2. When the sealing end cap is opened, the hydraulic oil in the cylinder body is discharged. This discharge of hydraulic oil causes the return spring to pull the piston block downward. As the piston block descends, it drives the limit pin downward, causing the limit pin to disengage from the limit hole. Once the limit pin is out of the limit hole, the hollow shaft can move freely left and right, making it easy for users to quickly disassemble the hollow shaft for repairing the propeller blades.

Through the coordinated use of the control mechanism 7 and the limiting mechanism 6, the user can quickly remove the hollow shaft body 3 to facilitate the repair of the paddle 4.
[0022] like Figure 2 and Figure 3 As shown, the limiting mechanism 6 includes a cylinder body 603 fixedly installed in the solid shaft body 1, a return spring 605 is provided in the cylinder body 603, a piston block 604 is movably installed in the cylinder body 603, a limiting pin 601 is fixedly installed on the piston block 604, a docking hole 606 is provided at the bottom of the cylinder body 603, an inlet and outlet through hole 602 is provided at the upper end of the cylinder body 603, the limiting pin 601 extends out of the cylinder body 603 through the inlet and outlet through hole 602, and a mounting groove is provided on the solid shaft body 1, and the cylinder body 603 is mounted on the solid shaft body 1 through the mounting groove.
[0023] Specifically, the piston block 604 can drive the limiting pin 601 to embed into the limiting hole 5, thereby quickly fixing the hollow shaft body 3 on the solid shaft body 1 for use. At the same time, the reset spring 605 will pull the piston block 604 to move downward, so that the limiting pin 601 disengages from the limiting hole 5. After the limiting pin 601 disengages from the limiting hole 5, the hollow shaft body 3 can move left and right, which is convenient for users to quickly remove the hollow shaft body 3 and facilitate repair of the blade 4.
[0024] like Figure 2 and Figure 4 As shown, the control mechanism 7 includes a cross connector 707 fixedly mounted on the cylinder body 603, the cross connector 707 is connected to a connecting pipe 704, the connecting pipe 704 is connected to a hydraulic sensor 705, the end of the connecting pipe 704 is connected to a control pipe 702, one end of the control pipe 702 is provided with a one-way valve 701, the other end of the control pipe 702 is provided with a sealing end cover 703, the connecting pipe 704 is provided with a detection port 706, the hydraulic sensor 705 is mounted on the connecting pipe 704 through the detection port 706, the inner side of the sealing end cover 703 is provided with a thread, and the sealing end cover 703 is mounted on the control pipe 702 through the thread.
[0025] Specifically, hydraulic oil can be injected into the cylinder body 603 through the control pipe 702, so that the piston block 604 will move upward, driving the limit pin 601 to embed into the limit hole 5, and at the same time the sealing end cover 703 can be opened. After opening the sealing end cover 703, the hydraulic oil in the cylinder body 603 will be discharged, causing the reset spring 605 to pull the piston block 604 to move downward, driving the limit pin 601 to disengage from the limit hole 5.
[0026] Working principle: When in use, the solid shaft body 1 is installed on the beating filter through the bearing. After the solid shaft body 1 is installed on the beating filter, the hollow shaft body 3 can be connected to the solid shaft body 1. After the hollow shaft body 3 is connected to the solid shaft body 1, the hydraulic oil can be injected into the cylinder body 603 through the control pipe 702. Since one end of the connecting pipe 704 is connected to the cylinder body 603 and the other end of the connecting pipe 704 is connected to the control pipe 702, the piston block 604 will move upward after the hydraulic oil is injected into the cylinder body 603. After the piston block 604 moves upward, it will drive the limit pin 601 to move upward. After the limit pin 601 moves upward, it will be embedded in the limit hole 5, thereby quickly fixing the hollow shaft body 3 on the solid shaft body 1 for use. At the same time, the user can open the sealing end cover 703. After opening the sealing end cover 703, the hydraulic oil in the cylinder body 603 will be discharged. Since one end of the return spring 605 is fixedly installed at the bottom of the cylinder body 603, and the other end of the return spring 605 is fixed to the piston block 604, the limit pin 601 is embedded in the hollow shaft body 3 through the limit hole 5. Therefore, when the hydraulic oil in the cylinder body 603 is discharged, the return spring 605 will pull the piston block 604 to move downward. When the piston block 604 moves downward, it will drive the limit pin 601 to move downward, so that the limit pin 601 disengages from the limit hole 5. After the limit pin 601 disengages from the limit hole 5, the hollow shaft body 3 can move left and right, which is convenient for the user to quickly remove the hollow shaft body 3 and facilitate the repair of the blade 4.
