[0023] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 , the present utility model provides an embodiment: a nut that is easy to replace, including a nut body 1. A fitting tube 3 is installed on the top of the nut body 1. The nut body 1 fixes the fitting tube 3 on the top to ensure the stability of the fitting tube 3. A first internal thread 2 is arranged inside the nut body 1, and the first internal thread 2 is arranged inside the fitting tube 3. A first anti-slip gasket 8 is installed at the bottom of the nut body 1. The first internal thread 2 extends inside the nut body 1 and the fitting tube 3. After the thread is sleeved inside the first internal thread 2, the user rotates the nut body 1 to make the internal first internal thread 2 rotate. The first internal thread 2 moves on the outside of the screw rod, so that the nut body 1 moves downward. During the downward movement of the nut body 1, the first anti-slip gasket 8 at the bottom increases the friction between the nut body 1 and the device to ensure the stability of the nut body 1. A through thread 4 is arranged on one side of the first internal thread 2, and the through thread 4 is arranged on the inner wall of one side of the nut body 1. A detachable fastening screw 5 is movably installed inside the through thread 4 through the thread. One end of the fastening screw 5 is installed with an internal hexagonal round head 6, and the other end of the fastening screw 5 is installed with an anti-slip plate 7. The anti-slip plate 7 is located inside the first internal thread 2. The user inserts the fastening screw 5 into the through thread 4. The inside of the nut body 1 limits the inner fastening screw 5 through the through thread 4. The fastening screw 5 moves into the nut body 1, so that the anti-slip plate 7 closely adheres to the outside of the screw rod. Through the contact between the anti-slip plate 7 and the screw rod, the friction is increased to ensure the stability of the nut body 1 and reduce the probability of the overhaul nut falling off after installation.
[0024] A second anti-slip gasket 11 is movably installed on the top of the nut body 1. A fastening cap 9 is installed on the top of the second anti-slip gasket 11.

[0026] Working principle: The user rotates the nut body 1 to make the internal first internal thread 2 rotate. The first internal thread 2 moves on the outside of the screw, causing the nut body 1 to move downward. During the process of the nut body 1 moving downward, the first anti-slip gasket 8 at the bottom increases the friction between the nut body 1 and the device, ensuring the stability of the nut body 1. The fastening screw 5 is inserted into the internal through thread 4. The inner side of the nut body 1 limits the inner fastening screw 5 through the through thread 4. The fastening screw 5 moves into the nut body 1. Through the contact between the anti-slip plate 7 and the screw, the friction is increased, ensuring the stability of the nut body 1. The probability of the nut falling off after the maintenance nut is installed is checked. The screw is installed inside the second internal thread 16 by means of a thread. During the process of the second internal thread 16 rotating and descending, the second anti-slip gasket 11 comes into contact with the nut body 1. The tightness between the nut body 1 and the fastening cap 9 is increased through the second anti-slip gasket 11, ensuring the stability of the nut body 1.
